Frequently Asked Questions

Will a power surge warranty cover the GE dishwasher control board?
GE's standard warranty does not cover power surge damage. However, homeowner's insurance or a separate appliance protection plan may cover surge-related board failures. Check your policy before paying out of pocket.
How do I know if it's the main board or the UI board causing 888?
888 is a main board self-diagnostic code. If the display shows 888 legibly, the UI board is likely functioning and the main board is the fault. If the display is garbled or completely blank, a UI board failure may be a contributing factor.
