CPAP Repair - My CPAP machine is broken!

Posted by Advans CPAP Staff on 7/16/2017 to Articles
So your CPAP or Bilevel machine is broken and needs repair? Let’s first talk about some of the most common issues people have with their CPAP machines. “Service required” showing up on Philips Respironics 50 / 60 Series or Respironics M-Series CPAP machine displays are probably what we currently encounter the most out of all CPAP repair inquiries. For the Philips Respironics 50 / 60 Series line of CPAPs, when you try and power the unit up, the motor will briefly attempt to spin and then stop. It will cycle on /off several times and then the display will flash “service required” along with a beeping chime. This typically means the blower motor will need replacement even though it seemed to operate completely normal the previous night. When this same symptom occurs on a Respironics M-Series CPAP, the majority of the time the component which regulates air pressure is corrupt. Replacement of the component will be needed to correct the issue. Whenever there is a loud noise such as scraping or roughness coming from the CPAP, it is caused by the motor as it’s the only moving component in CPAP machines. These noises are typically caused from a sudden impact such as a machine falling off a nightstand and hitting the floor. It can also be from either external dust or moisture contamination from an attached humidifier. Normal wear and tear on motors will be problematic over the years of nightly use as well.

More information will be posted about common CPAP machine problems and repair in future blogs. Check back soon!

I have the Philips respironics dreamstation. Auto cpap. I woke this morning to discover the blower is going (loud ,) but no air going to the mask. Wondering what that could be. Everything is attached etc and how would I repair it

Hello, Most likely the the Philips Respironics CPAP machine is loud and not blowing out any air pressure is because the motor has a broken flow connection. This can happen if the machine experienced some kind of sudden impact. Please complete our inquiry form in the CPAP repair navigation tab above and we can begin the process to repair your CPAP. Thank you.

The screen on my CPAP states the heater plate is not working and will be disabled. I use an airsense made by resmed. The machine still pumps air, but my mouth is drier than before. Is this something that can be repaired or serviced? I can't afford to by a new CPAP machine right now.

Hello, Your ResMed Airsense 10 CPAP can be repaired. There are two potential problems that can be causing the error on the display. Most likely, the heater plate has water damage will need replacement. The other issue can be caused by a corrupt main control board. We will not know exactly what the issue is until the unit is examined. Please check your email. Thank you.

My ResMed Airmini Travel CPAP that I just purchased makes a horrible wooshing sound as I breathe. I complained to the the place I purchased from, but they were of no help.

Travel CPAP machine like the ResMed AirMini are loud compared to home units. This is due to less sound insulation and them having smaller motors. The smaller motors have to work harder in order to keep up the proper air flow and volume. The AirMini has a heat moisture exchanger near the mask that creates lots of turbulence sounds as you breathe in and out. This is something you need to be aware of before purchase. Please see the video we created to help demonstrate the travel cpap noise and sound comparisons.

When I wake up in the morning there are small bits of black greenish colored material in the humidifier chamber. My machine is only 1 year old and I am worried about breathing it in. What do you think it can be and why is it happening?

Those bits may be foam insulation that has deteriorated inside the cpap machine. Typically caused by cleaning devices that uses ozone to disinfect the unit. Unfortunately, the ozone breaks down the insulation and rubber seals inside the unit over time. The foam will be sucked into the motor and damage it.

The pressure drops after about 4 hours and I have to suck my breath to get enough air

Pressure drops can occur when your mask develops a leak when you change positions. Air flow sensors or control boards can be malfunctioning as well.

Primary machine recently started making "wheezing" sound when I exhale. Very annoying. I also have a much older RemStar Plus that has an error code E-35 that I'm interested in having operable again as a back-up.

Wheezing sounds coming from your CPAP is a sign the motor is wearing out. It will need replacement. E-35 error code means the main control board and or motor is bad.

It’s not pumping out enough air to the mask ,it feels like it’s leaking though the back

Your air filter can be clogged, the motor may have shifted from its mounts or debris is inside the blower unit could be your issue.

I have a Philips Respironics REMstar Auto A-flex that has gone into “service required” error for the second time. I was able to get it to reset by unplugging and holding and releasing buttons but I did not write the sequence down properly and now I cannot reset it this time. Could you give an old guy some advice? I really don’t have the money for a new sleep study and equipment. I realize my equipment is old, but I’m pretty desperate. Thank you if you can offer DIY advice.

"Service required" is indicative of a component failure unfortunately. The only way to correct it is to replace the failed part. It would either be the control board or motor.

This machine was supplied by the VA. It called for a servicing so when I took it in they just replaced with a newer model. I was told to throw this one in the trash even though it still worked. I have a cabin in a somewhat remote area where I go for 3 days every week. I had packed it there since I first had it. When I receiver the new one I have kept this one there. The electricity is from a utility, not a generator, so it is stable. I have the data card still in the machine. The machine won't start by pushing button. After several tries with the digital output cycling, the beeper continuously beeps. Then I have to unplug it and restart the cycle. If I put the mask on and breath deeply, it will start after about 6-10 tries. Then it works well all night, as long as I keep it running. If I don't then the starting problem is the same. Thanks

When the unit cycles on and off attempting to boot up, that is a sign a component has failed. Depending on the machine it could either be a motor, control board or flow meter.

I have had my Resmed S9 crap unit for about 9-10 years and it has run faultlessly. Last night, I went to power on the unit and it was completely dead. No power, lights or anything. Holding down the power button did nothing. The power strip into which the unit is connected is fine as well. Would it be reasonable to order a replacement power supply to see if this is the issue? Amazon sells them and if that isn’t the problem, I can return it. Only thing I can think of as no malfunctions of any kind occurred prior to this. Thanks Eric Melanson

Check to see if the green LED light on the power supply is working when plugged in.
