DreamStation error codes

This is a listing of CPAP Error Codes and descriptions for Philips-Respironics DreamStation CPAP, Bi-level and ASV machines.

We do have the Service & Repair manuals for these and other CPAP machines available. To access them, you will need to join the Apnea Board Forum, log in, and then go to our Private Files and Links area, below the forums. In that forum, there is a post that says "Links to Members-Only Files". If you open that post, you can click on our current link to the Members Only Files. Please keep in mind that we do not have additional Service/Repair Manuals other than those listed on our Members Only Files page.

Levels of Error Codes

The four Error levels are described as follows:

Error Level	Description
STOP	The error information is recorded in NVRAM and the unit is placed into Safe State. The only functionality available to the user is serial communication, turning off the audible alarm via a key press and removing power.
REBOOT	The error information is recorded in NVRAM and the unit is rebooted. The fifth occurrence of a REBOOT level error within a 24 hour period (while power is maintained), will be promoted by the system to a STOP level error.
ABORT	The error information is recorded in NVRAM. The fifth occurrence of a ABORT level error within a 24 hour period (while power is maintained) will be promoted by the system to a STOP level error. This error is similar to a Reboot-Level Error with the exception that the system is unable to handle the error prior to the reset, e.g. watchdog timeout.
CONTINUE	The error information is recorded in NVRAM and the unit continues to operate without noticeable alteration.
