Error code E38 washer Appliance Repair Forum

Hi Friend, thank you for allowing me to assist you!

Typically an error code E38 on your Frigidaire washer could mean a few things:
First see if the air trap is clogged. If it is, that is probably the most likely issue.

If it is not clogged, it could either be the main control board, the water valve assembly or the pressure sensor switch.

To make sure it is not a false error code, reset the power to your appliance by either unplugging it or flipping off the breaker for about 30 seconds.

If the error code continues to display, I would strongly recommend contacting a professional to make the necessary repairs. Unfortunately, most electronic parts cannot be returned so it is always a good idea to get the appropriate diagnosis prior to making any unnecessary part replacements.

Best regards! - Z

Check your owners manual for code, service tech would have written it in. Check front pages of owners manual or service log. Or contact dealer for code.

These codes are not usually manually erased, they are overwritten as explained in the service book. Only the last so many codes are stored, beyond that they drop off. Pleazer Appliance...

Hi Scott Brown: Typically an error code E38 could mean a few things:

If these tests do not reset it is possible that the program controller processor is a suspect as there can be errors in the memory.

Your washer apparently did not complete diagnostics. The display indicates that it stopped at the segment of the test where it was attempting to fill by using the hot water solenoid. The diagnostic test segments check the following:

C:00 - Door Lock
C:01 - Flow Meter, Cold Water Solenoid
C:02 - Dispenser Motor, Dispenser Contacts
C:03 - Hot Water Inlet Valve
C:04 - Motor rotates CW at wash speed
C:05 - Heater & NTC (Heater Sensor)
C:06 - Drain Pump
C:07 - Motor rotates CCW at 35 to 90 rpm within 15 seconds
C:08 - Motor rotates CCW at max. speed.

If there is an error associated with any portion of the diagnostics, the washer will shut down, an audible alarm will be heard, and an error (F) code will be displayed. Sometimes the washer will experience momentray glitches during testing, however. I would recommend unplugging the washer for at least 30 minutes to reset the Central Control Unit (CCU). The is the main "brain" of the washer. Upon reset, attempt diagnostics again and let me know the results. I hope this helps you.
