No Delivery Alarms: 10 Questions to Ask When You Hear that 'Beep Beep Beep'

By Naomi Kingery

This morning when I was changing my site, I heard that “beep beep beep” that none of us likes to hear. I looked down at my insulin pump and saw an error that I have seen before “No Delivery.” I know many of you have asked why this occurs, so I reached out to our 24-Hour HelpLine Team to learn more.

First, they wanted me to remind you that “No Delivery” alarms, while they may seem annoying at times, serve an important safety function. Next, they provided me with a list of 10 questions to ask yourself to help you identify what’s triggering the alarm.

If the alarm occurs while priming:

1. Does my reservoir and infusion set have a secure and firm connection?
Make sure that it was a smooth connection when you were putting both of these together. If this is not connected correctly, the insulin may not properly flow from the reservoir through the tubing.

2. Could my insulin be bad or expired?
This is one of the main causes for a No Delivery alarm. If you have an extra bottle of insulin (preferably one with a different lot number) try using that to refill a reservoir with the new insulin to see if the error still occurs. Just because your insulin is not cloudy doesn’t mean it can’t be bad. If it occurs when you are wearing a set:

3. Does my infusion site hurt?
If your site is ever tender and you receive a No Delivery alarm, you may not be getting the insulin you need. If your site hurts, there may be a bend in the cannula underneath your skin, which is preventing the pump from delivering the insulin.

4. Am I using the right type and size of infusion set for my body type?”
As time goes by, our body types can change which means there may be a better suited infusion set for us. I personally used to wear a Quick-set and began to have site issues. So I worked with my doctor to try a few other options. I’m now using the mio, which has made a big difference (and it’s pink!).

5. Is the area of my body a site that is free of scar tissue?
If you have any scar tissue or areas of your skin where you commonly insert your infusion set, try inserting at another area so it doesn’t cause an unnecessary block for your infusion set. You can wear your site on the side of your arms, your abdomen, side of the thighs or your love handles.

6. Do I rotate the infusion sites enough?
Your infusion site should be at least 2 inches away from your belly button and 1 inch away from where you had your last set in. Try the “clock” method and “M” or “W” method to get into the habit of alternating site locations.   

7. Has it been longer than 3 days since I put on my last infusion set or
When you wear an infusion set longer than 3 days it can irritate the site and cause build up at the insertion area. If you use an infusion set like the Sure-T that uses a steel needle, you should only wear this up to 2 days.

8. Are there any bends in the tubing or kinks in the tubing?
If you wrap your tubing around your insulin pump or place it in a pocket, make sure there is not additional stress put on your tubing connection. If you wear your site under a belt line or in an area where your tubing commonly has pressure on it, this could also add additional bends in the tubing.

9. Is the adhesive or over tape still in place?
If you have a set that has its adhesive coming off and you decide to push it down with your fingers (I admit to doing this), make sure your blood glucose doesn’t go higher than normal because this could mean that while pushing down on the tape, your cannula may have shifted. This is also true for when you have put tape on top of your infusion set and try to take it off.

10. Is there insulin in my reservoir?
If there is no insulin in your reservoir this error can occur, perform a regular site change and make sure to fill up a new reservoir. When in doubt, change out your insulin, infusion set and reservoir (that’s what I did this morning, and it worked). If you decide to clear a No Delivery alarm the biggest precaution the 24-Hour HelpLine Team says to take is to keep a close eye on your blood glucose, because two unexplained high blood glucose numbers in a row can be a sign that you are not getting the insulin you should.

I hope this helped!

Thanks for the post, Naomi! The questions are pretty remedial, though, and that' likely the reason I never call the help line for that or even generally - because I can typically find more practical answers very quickly, rather than waiting a very long time and getting the form answers I knew before calling. Usually, it' one of the above issues, of course. But when it's not, I'm typically not interested in trial-testing every possible scenario and just getting the point across that something is up that really needs their attention. Overall, yes: No Delivery alerts are annoying but do serve a purpose.


Posted on Sun Jul 10 23:42:00 GMT 2011

Hi Mike - yeah, these may seem like pretty basic issues, but they are the most common reasons people get no delivery alarms and the reason behind a large majority of the calls our HelpLine receives on the topic, which is why Naomi wanted to address them here -- and why the HelpLine tries to tackle them first when customers call.

I really need help with my pump!! For the past month my Revel pump has been saying "no delivery" many times a day. I have changed my site, changed my tubing and so on. This past week I have found where the error is, but I don't know how to fix it. I disconnected my site from my body then took out my reservoir inserted the plunger and pushed as hard as I can, but NO Insulin will come out of the end of the tubing. With this problem I have gone through a whole box of supplies in a week. What am I doing wrong or what is going wrong with my supplies? I have called the help line many times and they have solved the problem while I'm on the phone with them, but about an hour or so after I hung up with them I get another "no delivery" alarm. My blood sugar has been so messed up because of the problem. It has effected my performance at work. Please help me!!!!!!

I have also been getting no delivery alarms off and on for the last few months. I have a medtronic paradigm pump (recently replaced). I cannot make sense of any of the errors. I have changed injection sites numerous times, changed insulin numerous times, changed batteries. There seems to be no logical reason I keep getting so errors. There is no kink in the tube either. It is getting to the point where I am considering going back to shots and giving up the pump altogether. Does anybody know if I can just admit myself to the hospital until this is figured out? Tjios is costing me a small fortune in pump supplies and insulin, as well as running out of supplies before insurance will pay for them so I have to pay out of pocket. Somebody please help.


Posted on Sun Sep 16 16:46:41 GMT 2012

Chris, I'm sorry you are experiencing this problem. I'm going to have someone contact you at the email address you provided to get additional contact information and to try to help.


Posted on Thu Nov 15 04:00:31 GMT 2012

Having the same issues chris. sometimes i can do a rewind and it will work ok for a few hours and then back to no delivery.... and when you call medtronic help they want to tell you when your warranty runs out and then have you do everything you have alreay done. and then they think you need to tell them what you want them to do since you don't want to hear about the warranaty and the other rigamarow they go through. it cost me more to buy my pump supplies if i turn it into my insurance so i buy it out of pocket cheaper than the insurance can get it for. Also my second pump in less than a year. my pump sounds like a thrashing machine. and the lady i talked to said she heard it before. I was wonder when she was at my house. I told her she had good ears LOLO. anyway as much as the PUMP cost it should work better than it does. I got so mad at this thing i took it off and I am going to start using the shots again and see if i can get my money back!!!!! and start looking for another pump company.

Happy and sad to see that others have had the SAME problems I am having here-have had about 12 pumps in past 4 YEARS and now a new model "update" to Revel has lasted for LESS THAN 6 WEEKS. And the CSR (2) were LESS than helpful and the NEW script seems to be--it is ALL THE CUSTOMERS FAULT. Um--no. I have gone thru 5 different sites and complete infusion set ups and reservoirs in past 48 HOURS to no avail-proved to CSR that THERE IS NO INSULIN GOING THRU CANNULA--still somehow MY FAULT and they don't wanna know or help. The REP here is no help when you can track her down. Sending me an email after I call is NOT customer support. We depend on these machines to keep us alive and the shocking failure of the company to care about this is malpractice in my book. Once AGAIN I AM ON MY OWN WITH A $7000 PAPERWEIGHT. Don't think that the FDA and other interests will remain ignorant of this. And all of the "company sponsored cheerleading" on the fake Blog---bah.

Wow this is great and awful at the same time! My sister and I both are pump users and have MANY of the same problems. always always always super tender and painful around the insert site, leaking- making it so we have to change the site every other day, and bleeding at the site-through the tube. I don't seem to have as many issues with the no delivery part but have had a few in my 5 years. I agree they are way too expensive to be wasting them as much as we do but no other choice really. I too will be returning to daily shots as soon as supplies run out. I was impressed at first but not anymore which saddens me because I know the pump is beneficial for many reasons but heck! This is my second pump within 5 years and now I have no insurance. It was barely affordable before and now not at all. 1 vial of insulin costs me $125! Put supply cost on top of that = broke! If they worked the way they were supposed to it would be easier to swallow but I hate throwing my hard earned money away on something I need to survive.

It is 2:30 am and I am on my 4th infusion set of the day! My blood sugars have been ridiculously high...every time I have changed the infusion set today I find a crimped cannula.
I use the medtronic quickset w/ 6 mm canula. I am very frustrated, also feeling sick as the blood sugars rise...I do not get "no delivery messages" on my pump so it is a total guessing game for me...when I get into the 300's I figure something is wrong. Today I have been right. I am also frustrated and think I should go back to injections. And IT IS NOT ME. YES I exercise at a gym and I ride bike, fast....I asked a trainer if that was a problem ..she just looked at me like she did not believe me and said don't put it where you bend...I don't.
I have tried many sites...I do not have "help" to put it on my arms or on my back, I have lost 20 lbs and am very active at 63 years old. Something has got to change.....HELP

I am having REPEATED NO Delivery alarm issues with my insulin pump. This pump is the upgraded Paradugm pump from 1 month ago. I had never had these issues with my old pump. My blood sugars are consistently 200-300 in the morning. Please contact me ASAP to discuss. I have claaed but I end up waiting 30 minutes to talk.

Glad to see I am not the only one to have had problems with this thing. I went back to the shots because it is much safer then the pump.

Doug, I’m glad to see you’re finding useful information on our various blogs. I’m sorry you had a negative experience, and again, if there is anything I can do to help you now or in the future, please let me know.

I am having the same problem. Either "No Delivery" errors or, worse, I get no error. I do not know anything is wrong until hours later when my blood sugar goes up into the 300's. Once, I ended up in emergency with 550 blood sugar.

I have called the help line so many times and tried everything they say.

I have tried the quick set and the Sure T. The Sure T would not work at all. I changed it 3 times and got nothing but "No Delivery. So I went back to the Quick set.

I change infusion sets at least once a day, sometimes twice. It works for a little while and then stops. I am very thin and have tried sites all over my abdomen and love handles area. There is no fat on my thighs, so that's out.

I think I will have to go back to shots because I cannot afford the cost of changing infusion sets twice a day, but the thought of sticking myself 5 times a day is so disheartening.

I have a radiology scan scheduled that requires no metal be worn, and normally I use the Sure-T infusion sets with the metal needle. I decided to switch temporarily to the Mio, watched the instructional video and inserted it as per instructions. Within an hour, my meter readings began to climb and I realized the skin around the infusion site was starting to get red and swollen. I began to get no delivery alarms. I immediately removed the Mio cannula to find it visibly bent and it appears that the insulin has infiltrated just under the skin. The site is bumpy and fluid filled. I inserted my regular Sure-T and injected a bolus to cover my high glucose reading but am concerned: what happens when the infiltrated insulin is eventually absorbed and how long will the swelling at the site take to go down?

I have noticed the resivors and the connector on the tubing do not fit tight like they have been cheaply made. I have had issues where one day the pump works and next time I change my site 2-3 days It does not work like it should. I use the quickset sites with the 6mm canula and I at times have removed perfectly good sites no canula kinks etc and the reservoir delivers insulin out of the connector on the site. If it works it works but lately I would rather throw it in the road than risk my well being I am disabled and that is bad enough then top it off with a pump and supplies that don't work like they should. I would rather take injections again. I have been pumping since 2004 I am not new at this and there have been more recalls and problems than it is worth. My pump acts like it is working fine no alarm site is good as well then I test my sugar 250+ and rising. Or I hear drink some water from the help line etc etc what bs it should work. I am so tired of the troubles of this piece of crap device I am about to try a different pump company. I can't take the stress any longer. I wish the owners of Medtronic were diabetic and used these and had to rely on devices and supplies that do not work properly. My pump is a paradigm 723 and the cheaply made supplies I have been getting for it are junk I love paying high dollars for stuff that is not reliable. Either help me with these issues or I will send my pump back and you can refund my money I can afford to die or become blind etc from the low quality products I have been receiving.

Bradley, I’m very sorry to hear this. Please know that, at Medtronic, making quality products that you can trust is our top priority.

I am having this same issue and I am seriously considering going back to shots. At first it was a great way to keep me from dropping (that was the reason for putting me on the pump) but this junk just continues to happen and I am like most of you that cannot afford to waste insulin or supplies because of this no delivery problem. Now I think this pump may be worse for me than shots and while I hate to do it, I think I may have to go back to shots as this all comes out or our pocket because it's cheaper than using insurance. I always call when I have a problem but this is getting really old. I guess Medtronic just seems to have more issues than I can afford to deal with.

I have been getting "no delivery" alarms when I change my set. I use the Mio and thought at first it was the reservoir, but now I think it is the connection with the Mio. It seems very wobbly and weak. Sometimes it connects and sometimes it does not. I never had this problem until recently. Going to stick with it and see what happens. Was a little frustrated today trying to get it to work, but finally did.

And this happens often lately.I am on egg shells every time I change my site.Anybody having the same problem ?

Upgraded to a Real Time Revel about a month and a half ago, constant No Delivery alarms. Constantly! Everything is changed, same alarm! New site, same alarm. Is it really this sensitive?! In the meantime, my BG is rising with little correction or food coverage. Never had this issue on this level before. While support is nice, nothing from my past experience in dealing with similar issues has had a resolve.

I've had priming problems with 4 sets so far in the past two weeks. I checked everything numerous times and ended up replacing infusion set. Unfortunately, now I am 4 sets fewer on my supplies. I'm afraid this may continue to be a problem with these sets.


Posted on Fri Apr 04 16:16:00 GMT 2014

Hi Harry. I am sorry to hear you’ve been experiencing priming problems with your infusion sets. I will have someone from my team reach out to help and make sure you are taken care of. Please keep in mind while changing an infusion set, if insulin, or any liquid, gets on the inside of the tubing connector on the infusion sets, it can temporarily block the vents that allow the pump to properly prime.

If there is a kink in the cath, should I be getting a "no delivery" alarm?

Hi Lorie, if you're getting a no delivery alarm please call the HelpLine at 1.800.646.4633, option 1. I will also notify them of your issue.

I have the same issues, 3rd paradigm pump from medtronic. 9 no deliveries in under a month with the new pump. It's so frustrating. Often I get a No Delivery, put in a new site, change the reservoir and almost immediately I get another no delivery (if I am bolusing). It's especially frustrating because the no delivery alarm seems to not occur until 2.5 to 3.0 units of insulin should have been delivered, which in effect, under basal conditions, means that for several hours I receive no insulin prior to the alarm occurring. My blood sugars are ridiculously high and I almost have no option but to go back to injections. It's not clear to me why these pumps have these problems with so many users, but it's incredibly frustrating. Sadly the best that medtronic can do is send a replacement pump, but I've had two so far, and it hasn't helped the problem. There is clearly another issue with some individuals with the medtronic pumps and infusion sites. I just wish there was a better solution than going back to injections; as Judith said above, I feel like I own a $7,000 paperweight.

I have been a user of Minimed/Medtronic pumps for nearly 14 years. Last year they discontinued the infusion set I had always used and I switched to the Quick-set with 6mm canula, In more than 13 years, I could count on one hand the number of no delivery alarms I got, now, one hand doesn't cover a typical week. I had a lot of trouble with the first box of infusion sets, but had better luck with the next two boxes. I started a new box on Sunday and had to change the set and sight 5 times to get one that worked. Today, completed a routine set change and have resumed with "No Delivery".
I'm on my second set so far and continue to have problems.

Aside from the added cost and waste of supplies and insulin, I can't always spend hours jerking around trying to get my pump working properly. I hate the new infusion sets and would give anything to go back to the old Soft Sets I used to use that seemed to have sturdier connections. Medronic - if you can hear me, these Made in Mexico and Made in Puerto Rico items are junk and if it continues, you can be sure that my next pump will not bear your name! I understand you are in business to make a profit but this business must have QUALITY products BEFORE PROFIT.


Posted on Thu Jun 12 16:51:47 GMT 2014

Hi Diane. I am sorry to hear you’re frustrated and have had a negative experience with the Quick-set infusion set. Please know that the safety and durability of our products is very important to us. I know it’s disappointing when a product is no longer available and we do not make the decision to discontinue lightly. Sof-set was our oldest cannula infusion set and, unfortunately, we’re unable to manufacture it any longer. We do have other infusion set options and are here to make the transition as seamless as possible. I will have someone from my team contact you to talk about other options. In the meantime, you may find this article on our different types of infusion sets helpful:

I have had nothing but problems with my paradigm pump for what seems to be years. In the last 6 days I have gotten numerous no delivery alarms. I have changed reservoirs, sites, infusion sets, insulin, anything and everything. This is my THIRD replacement pump and I am less than satisfied with it. I have ended up in the hospital DKA more than once due to the faulty insulin pump tubing and malfunction with no insurance. So, thanks for the thousands of dollars of medical debt I'm stuck with paying. Anyway I can return the last two boxes of infusion sets i bought and just get my money back? Im definitely returning to injections, I am more than sick and tired of feeling like death because of this garbage machine.


Posted on Mon Jul 14 14:55:40 GMT 2014

Ashley, I’m so sorry to hear you’re having issues and disappointed with your insulin pump. I understand that it must be frustrating. I will have someone from my team reach out to you to see if there is anything we can do to help. If there’s anything else I can do, please let me know.
