The blower may be faulty and needs to be replaced.
Why is my Breas Clearway 2 very noisy during treatment?
The blower may be faulty and needs to be replaced.
What to do if my Breas Medical Equipment is showing a pressure fault (mismatch)?
Check the pressure tubes to ensure they are properly connected and not kinked. If the tubes are fine, the pressure transducer may be faulty, requiring replacement of the power PCB.
Why is my Breas Clearway 2 very noisy in standby?
The cooling fan may be faulty and needs replacing.
Why is the maximum pressure not reached on my Breas Medical Equipment?
Check the calibration. Also, inspect the internal airpath for leaks. The valve or blower may be faulty and require inspection. It is also possible that the power PCB is faulty and needs replacing.
What to do if my Breas Medical Equipment Clearway 2 does not switch on when connected to AC mains, and the AC LED is not lit?
First, verify the mains supply to ensure there is power at the socket. If the socket is functional, check the fuse in the mains cable plug. If problems persist, there may be a faulty power supply, in which case you should verify the PSU DC output and replace the PSU if it is faulty. A faulty Power PCB could also be the reason, so it should be replaced if necessary.
What to do if my Breas Medical Equipment battery will not charge?
If the battery isn't charging, the battery may be faulty and needs replacing. Alternatively, the Power PCB may be faulty and also needs replacing.
What to do if my Breas Medical Equipment Clearway 2 does not switch on when connected to AC mains, but the AC LED is lit?
Check the front panel connection to the display PCB. If the connection is secure, the front panel may be faulty and require replacement, along with the display command PCB. Also, the Power PCB could be faulty, and replacing it might solve the problem.
What to do if my Breas Clearway 2 Medical Equipment blower does not run during treatment, resulting in no airflow?
Check the blower connector and cables to ensure they are properly connected. If the connections are good, the blower itself may be faulty and require replacement. A faulty Power PCB could also be the cause and may need replacing.
What to do if my Breas Medical Equipment Clearway 2 does not switch on when running on battery power?
Check the battery cables to ensure they are properly connected. If the cables are secure, verify that the battery is charged. If the issue persists, the Power PCB may be faulty and require replacement.
What to do if my Breas Clearway 2 manual switch is not working?
Check the function with both the front and remote switch. Also, check the switch connection CON 2 on the display PCB. If those don't work, replace the switch.
