If you have sleep apnea, CPAP machines (Continuous Positive Airway Pressure) can change your life. But what should you do if your CPAP machine stops working? It can really mess up your sleep and health if your CPAP machine won’t turn on, isn’t blowing air properly, or is showing error codes.

This article will show you how to fix common problems with your CPAP machine and when you should think about getting a new one or getting help from a professional.

1. The CPAP machine won’t start

If your CPAP machine won’t turn on, try these simple things first:

• Check the source of power: Make sure the outlet works and the plug is in the right place.
• Check the power cord and adapter for any visible damage.
• If you have a ResMed AirSense 10 or 11, try unplugging it for 30 seconds to reset it.
• If your CPAP machine stopped working after a power outage, the problem might be with the surge protection or the fuses inside. 
• Use a surge protector in the future.

2. The CPAP machine isn’t blowing air the right way.

If your CPAP isn’t giving you enough air, it could be because: 

• The mask is leaking 
• The tubing is blocked 
• The air filters are blocked 
• The pressure settings are wrong.

Check the settings on your machine and the mask and tubing. Check your machine’s manual or our CPAP Support Section if you don’t know how to do this.

3. The CPAP mask leaks and the pressure drops.

The mask leaking is one of the main reasons why CPAP machines don’t work right. A leak not only makes therapy less effective, but it also makes noise that can wake you up.

Here are some fixes: 

• Changing the type or size of the mask 
• Changing the straps on the mask 
• Putting new cushion seals in place of old ones

Respbuy has a lot of CPAP mask parts and accessories that can help stop leaks.

4. The humidifier for the CPAP machine isn’t getting hot.

If your CPAP machine’s water chamber isn’t heating up, it could be because: 

• The humidifier plate is broken 
• The humidity settings are wrong 
• Mineral buildup is blocking the heater

Look for limescale buildup and clean the chamber on a regular basis. You might need to buy a new part if the same problems keep happening.

5. The CPAP machine makes strange noises.

If your CPAP machine makes strange noises, it could be because: 

• Parts are loose 
• Filters are vibrating 
• The mask doesn’t fit well.

Make sure that everything is hooked up correctly and that your mask fits well. If the sound keeps happening, check your device for problems inside or go to our CPAP troubleshooting page.

6. What the error codes on your CPAP machine mean

Most new machines, such as the ResMed AirSense 10 and the Philips DreamStation, show error codes to help you figure out what’s wrong. Check your user manual or call Respbuy support for help with specific errors.

7. When to Get a New CPAP Machine

If you’ve tried everything and your CPAP machine still doesn’t work, you might need to get a new one. You might need a new one if you see any of these signs:

• Makes a lot of noise 
• Pressure that isn’t always the same 
• Lots of error codes 
• Damage to the body

You could look into highly rated options like the Philips DreamStation Auto CPAP and the ResMed AirSense 10 AutoSet.
