GE Washer Error Code 01

Error code 01 on a GE washer indicates a UI EEPROM fault, meaning the software stored on the User Interface control board is not operating correctly. The EEPROM is the memory chip on the UI PCB that holds configuration data and the model ID. The washer's control system detected that this data is corrupted or invalid. A technician can attempt to clear the code using Service Mode test T27 and verify the model ID with test T2 before concluding the board needs replacement.

A basic power cycle or reset may temporarily clear error code 01, but if the underlying EEPROM data is corrupted or the UI board has failed, the error will return. The correct procedure is to use Service Mode test T27 to clear the code, then verify the model ID with Service Mode test T2, and then perform a power cycle. If the code comes back through this process, resetting alone will not resolve it.

If clearing the error through Service Mode resolves the issue at no parts cost, you only incur any applicable diagnostic labor fees. If the UI PCB requires replacement, parts typically range from around 80 to 250 dollars depending on the specific model, with additional labor costs if a technician performs the repair. Getting a repair estimate before proceeding is advisable, particularly on older machines where the repair cost may approach the value of the appliance.

A knowledgeable DIYer can attempt to clear the error using the washer's Service Mode test T27 and then power cycle the machine to see if the fault returns. If the error comes back after clearing, the UI PCB needs to be replaced, which involves working with the machine unplugged and accessing the control panel assembly. Replacing the UI board is a moderate-difficulty repair that requires some comfort with disassembling appliance control panels.

Error code 01 indicates a problem with the UI board's software memory, which means the washer's control logic may not be functioning reliably. Running a wash cycle while this fault is active is not recommended, as the control board may not properly manage cycle operations or respond to input commands. It is best to diagnose and resolve the fault before using the machine.
