Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does LOC mean on a GE Appliances dishwasher?
On many model families, LOC indicates that control lock is enabled. Confirm the exact model and region because the same display can be used differently.
Can I clear LOC by unplugging the dishwasher?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
