CPAP Machine Error: Safe Checks Before Calling Your Provider
Quick answer
Start by reading the complete message and recording the model. Stop therapy, disconnect power at the device connector, inspect only user-accessible filters, tubing, and humidifier parts, and perform one restart only when the model guide directs it. Do not open the device or change therapy settings to work around a fault.
Start with the exact message
Write down the complete display message and the model name before disconnecting anything. Numbered errors and display messages can have different meanings across device families.
Exterior checks only
- Stop therapy and remove the mask.
- Disconnect power using the device power connector or power supply.
- Inspect the external air filter and air tubing for blockage, kinks, damage, or water.
- Where fitted, verify that the humidifier tub or side cover is seated correctly and dry.
One restart, when documented
Reconnect power and perform one restart only when the user guide for the exact message and model allows it. Repeated resets are not a substitute for service.
When to stop
If the fault returns, the device is unavailable, or the guide calls the fault unrecoverable, contact the CPAP equipment provider or authorized service center. Follow your care provider's guidance if therapy is unavailable.
Do not open the enclosure, calibrate the device, enter undocumented service menus, replace internal parts, or change therapy-pressure settings.
