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.

Feel free to post a question or comment about CPAP repairs or your CPAP that is malfunctioning.

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. https://www.youtube.com/watch?v=BZI2cy3MI4s

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?
Advans CPAP Staff
Date: 9/11/2019 5:26:00 AM
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
Advans CPAP Staff
Date: 9/20/2019 1:53:00 PM
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.
Advans CPAP Staff
Date: 9/20/2019 1:56:00 PM
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
Advans CPAP Staff
Date: 12/4/2019 11:43:00 AM
Check to see if the green LED light on the power supply is working when plugged in.

My philips dreamstation blower seems to function fine, but not getting any humidification and it is set at 5. Hot plate is not getting hot either. The hose is also set at 5. Possible I need a new heated hose. I also use a SoClean, hope that isn't interfering with the hose, although it does not heat without it being installed, which is why I think I need a new hose. Is it possible that something got turned off while traveling with the unit? Pretty sure the settings are the same. If humidification is set at 5 the heat should come on, right? Normally its at 2 or 3. I am pretty handy with electronics and used to doing my own repairs. Hate to shell out $200 for something I can fix myself. I saw the heat plate, looks like an easy change out. Any advice is appreciated.
Advans CPAP Staff
Date: 4/6/2020 4:53:55 PM
Yes, it should get hot within 30 seconds if the setting is 5 on the display ( bottom right hand corner with 3 squiggly lines). The heating element in the humidifier is not replaceable on your unit unfortunately.

I have resmed s9 autoset. 4 years ago when I got it, the respiratory therapist broke off the right side selector knob. That always annoyed me, but now, I can't see the settings, my doctor retired and turned me over to another physician in the group, the group was purchased twice, and now my physician says she cannot find any records and has no idea how to generate a prescription. To make it worse the medical supplier relocated and I can't remember the name. If I could jut read the current settings I would be so glad. Can this knob be replaced?
Advans CPAP Staff
Date: 4/24/2020 1:22:11 PM
Yes, the knob can be replaced. If the metal shaft that the knob is pressed into is missing, then you will need a new control board as the shaft is part of it.

1. Machine sometimes does not want to turn on or takes a a couple of seconds to get full power. 2. When machine turn on the air flow is very high. I put on the mask and it does not let me exhale out the air. It pushes the air very fast that I am not able to exhale out. It all happened after I dropped it one time. This machine has never dysfunction before.
Advans CPAP Staff

The main control board has integrated flow sensors on them and is typically what regulates airflow depending on the make and model. Older CPAP devices will have stand alone air flow sensors. If your unit is blowing out unusually high pressures after having an impact, the air flow sensor is most likely damaged. If your sensor is part of the main control board, the board will need to be changed out.

My machine is a Philips responics Remstar Pro C Flex+ System1. I purchased it in 2011 and it has performed quite well I guess until now. I'm in the process of getting another but have to jump through all the hoops and obstacles of new prescription etc. I have a maintenance background(not much for electronics) and I feel as if I can repair most anything that runs. I have taken the CPAP apart and thoroughly cleaned it and reassembled. I was a little surprised by the good condition it was in! OH I was getting the SERVICE REQUIRED signal on the display with the beep,beep and if I depressed the control knob the light would go out but continue the beeps. I've been without the machine 12 nights now and don't really want to spend a lot of money on it but it would be nice to have it in run condition as a spare and I would consider leaving it at my Daughter's to use when I travel there to see my GRANDSON(one and only grandchild). Could you impart to me a simple way to check it so I could tell if it is the PCA board, Power Supply, Fan Motor etc. Shipping to your place I believe would be a little cost prohibitive for me. Thank you and let me know if you can help me or not.

"Service required" error messages are displayed on Philips Respironics 50 / 60 series and older M-Series models only. This error message normally indicates there is a faulty component in your CPAP machine. An example of how to interpret this is like a check engine light flashing in your vehicle. The car will need to be scanned for codes. Those error codes will then need to be interpreted as to what components are faulty. This is how your CPAP errors are read as well - via codes downloaded using our testing system. With that said, your unit has two main components, the main PCA and motor. Normally it is either one or the other, but rarely both. There is no simple way to check on your side without the proper testing equipment.

I completely screwed up and added far too much water to my water chamber. My Phillips Respironics System One ran for a night w/ that issue in place, before I realized what I'd done. Now my display reads Service Required, and the blower won't work.

The blower motor may be water logged and has seized up. It is something we can take care of for you quickly.

No that is not a part number. It is used during diagnostics with the factory. We troubleshoot with other codes that are logged into the unit our system can pull from the device once in hand.

I have a Philips Respironics C pap REMstar Auto A-Flex REF 550P. Air flow is good when I inhale but the machine bogs down when I exhale. Motor then seems to labor. If I resrict air flow at end of hose motor labors & I can hear slow down. Does motor need to b replaced? Thanks. l
Advans CPAP Staff

Yes, the motor could be bad or your air filter / intake is clogged.

My CPAP making a loud noise when I inhale. Sounds like an air leak of some sort. I already tried replacing the output tube that has a plastic gasket where the humidifier interfaces with it on the inside and where the breathing tube attaches to it on the outside, but this doesn’t fix the loud noise it makes when I inhale.
Advans CPAP Staff
Date: 5/18/2020 11:36:31 AM
Try isolating where the noise could be coming from. Start from the mask and remove each component from the air circuit until you can tell the source is coming from.

During use of the CPAP in Germany the power outlet converter failed and the CPAP stopped working. Upon return to US I replaced the ac power adapter and repowered the CPAP. The screen lights up and message reads “check power” . The air blower / fan is not running.

I have a REMstar Auto M series. It has low pressure. I tested it by booking my hose to the inlet hole to the air chamber - full pressure. Hook it up normal - no pressure.
Advans CPAP Staff
Date: 5/18/2020 11:33:23 AM
With your issue, it is difficult to determine what may the issue with your device without measuring the actual airflow coming out. It could be some clog or blockage inside the unit.

I have a REMstar Auto M Series Model #511M. It fell off the table onto the floor. Everything still works, except it always blows at 100%, never less. If it was a motorcycle I'd say the throttle was stuck on full. What might be the fault causing this? Thank you!
Advans CPAP Staff
Date: 5/26/2020 5:50:49 PM
You could not. It would need to be checked for error codes logged into the unit on our side. Once noted, we would know what component is faulty.

I have a 3 year plus Dreamstation and the day after I cleaned it with probably toooo much water, it only blows at a high level and displays the Service needed on the display. Can you give me an idea of what my costs will be? Prefer to NOT send it in if we/you already know your cost to repair will be too much with limited Social Security only income.

After a few hours devices cycles off and on a few times trying to restart and then beeps steadily and service required shows on screen.

Gradually over time, my machine has balked more and more at starting up when my breathing should be triggering it. The machine will make noises like it is trying to start, and that is accompanied by sporadic beeps. Sometimes that happens a few times, then it starts. Once it starts, it never quits until I turn it off. It has never quit once it got going. Frequently now, it does the above routine several times, then begins making constant repeated beeps at a regular interval, like every second or two. The readout says "needs service." Since this isn't my first tech rodeo, I then go to the time-honored unplug routine. I pull the power cord out, wait about 60 seconds, re-plug-in. Generally, it will start (usually after more fits and starts) after that. But now, I am having trouble trying to coax it into working, period.

The flow sensor on the main PCA could be causing start up issues.

The "on" button does not turn the machine on so I am unable to check anything or use the machine. However, a week or so before it quit, my daughter stayed overnight and declared either the machine or I was making so much noise she couldn't sleep.

Depending on the make and model of your machine, the switch may be repairable or the control board with a new switch may be needed.

I have a Remstar m series model 100M CPAP machine . When I plug it in all I get is a 300 tand hourglass and 2.3. It wont start. When I presss the power button,I get a 1 with 3 little mountains on the top,then 8.0cm h2o and it cycles like that for about 1 minute . Then both thr ramp and power buttons blink fast and a triangle with an exclamation point is all that is on the screene. Any thoughts? Is it a cheap fix or is the machine trash? Thanks
