ResMed CPAP Error Codes: Complete AirSense 10 and 11 Fault Guide

Quick Answer

ResMed AirSense 10 and AirSense 11 use a layered error code system that is specific to their blower motor architecture and ClimateLine heated tube integration. E-codes (single or two-digit numbers) indicate hardware faults in the blower motor, pressure sensors, or climate control system - most require contacting your DME provider or ResMed support.

ResMed AirSense 10 and AirSense 11 use a layered error code system that is specific to their blower motor architecture and ClimateLine heated tube integration. E-codes (single or two-digit numbers) indicate hardware faults in the blower motor, pressure sensors, or climate control system - most require contacting your DME provider or ResMed support. Three-digit codes like 001 and 006 are therapy alert codes that often resolve with mask adjustment or device reset. HOS Panic codes (like HOS Panic 06) are firmware-level crashes that resolve with a factory reset via Settings > Device > Reset. The snowflake symbol is not an error code but a temperature warning - the device is below 41°F (5°C) and will not start therapy until warmed to room temperature.

Frequently Asked Questions

What does it mean when my ResMed shows a number on the screen?
A number displayed on the ResMed AirSense screen after therapy ends or during startup is an error code indicating a specific fault. Single or double-digit numbers (1, 6, 12, 13, 21, 24) are hardware E-codes. Three-digit numbers (001, 006) are therapy alerts. Write down the exact number and consult the specific error code article or contact your DME provider.
Can I keep using my CPAP when it shows an error code?
It depends on the code. Therapy alert codes (001, 006) may allow continued use after a reset or mask adjustment. Hardware E-codes (Error 12, 13, 24) indicate a failed component and the device may not deliver your prescribed pressure accurately. Do not rely on a device showing hardware error codes for therapy - contact your DME provider for a replacement unit while yours is repaired.
Does ResMed cover CPAP repairs under warranty?
Yes. AirSense 10 and AirSense 11 carry a 2-year manufacturer warranty from the date of purchase. Most hardware fault codes (Error 12, etc.) are covered if the device was not physically damaged by the user. Contact your DME provider first - they handle warranty claims with ResMed on your behalf. ResMed direct support is available at 1-800-424-0737.
What is the difference between an error code and the motor life exceeded message?
Error codes indicate active hardware or firmware faults that affect therapy delivery. The Motor Life Exceeded message is a maintenance notification - not a fault code - that appears when the device has logged a significant number of therapy hours. The device continues to function normally after this message. However, it is a signal to schedule a check with your DME provider.
