What Error 013 means
ResMed Error 013 is documented as a CPAP device fault. The available service documentation contains additional internal diagnostic detail, which is separated below because it is not a consumer repair procedure.
Meaning varies by model or source
- AirSense 10 - Altra Service Professionals field reference (authorized ResMed service center): The pressure sensor is not reading properly. This can be caused by the device being out of calibration, the sensor becoming dislodged from its seal, or being faulty. If calibration doesn't correct this problem, then the main PC board will need to be replaced. This will need to be sent to a ResMed Authorized Repair Center to be serviced
- AirSense 10 - ResMed official user guide: System fault, Error 0XX: an unrecoverable error has occurred on the device. Contact your care provider; do not open the device.
What you can safely check
- Stop therapy and read the complete displayed message before doing anything else.
- Disconnect power using the device power connector or power supply; do not open the enclosure.
- If overheating is implicated, move the device away from heat and allow it to cool before reuse.
- Inspect the external air filter for blockage and replace it only as the user guide directs.
- Inspect the air tubing for blockage, kinks, damage, or water.
- Where relevant, verify that the humidifier tub or side cover is seated correctly and dry.
- Reconnect power and perform ONE restart only when the manufacturer's user guide allows it for that message.
- If the fault returns, therapy is unavailable, or the message is unrecoverable, contact your CPAP equipment provider or authorized service center. Follow your care provider's guidance if therapy cannot be used.
What not to do
- Do not open the enclosure or replace internal electronics, blower hardware, sensors, or boards yourself.
- Do not perform calibration, enter undocumented service menus, bypass safety mechanisms, or change therapy-pressure settings to work around the fault.
