This guide explains how to access and use the service mode on your GE GFWR4805FMC washer to perform diagnostic checks

Understanding Idle State of GE Washer

To enter service mode, your GE GFWR4805FMC washer needs to be in the “Idle State.” This means the washer is completely off and not in the middle of a cycle. Ensure it’s turned off but remains plugged in before attempting the button sequence.

To ensure this:

  1. Turn off the washer using the Power button.
  2. Do not press any buttons or adjust settings.

  3. If successful, the washer will enter service mode and display “Test 01” by default.

Important Caution Regarding Test 23 (Clear EEPROM)

Test 23 (Clear EEPROM) should never be used unless you are a qualified appliance technician with the proper tools.

Clearing it without the ability to rewrite it using a GE service diagnostic tool can render your washer inoperable.
