What the Lock error code actually means

The Lock light on your GE dishwasher is showing because the appliance has entered a special diagnostic display mode used to show error information. This is not the same as a broken door lock. Once you exit this diagnostic mode using the control panel buttons, the Lock light should turn off and the dishwasher should return to normal.

Questions people ask about Lock

What does Lock mean on a GE dishwasher?
On a GE dishwasher, the Lock indicator light is always illuminated when the unit is in Error Code Display Mode, which is also called Consumer Error Mode. This is a built-in diagnostic state and the Lock light in this context is a status marker, not a sign of a broken door latch. Exiting the diagnostic mode through the control panel will turn off the Lock indicator.
Is it safe to use my GE dishwasher when the Lock indicator is on?
When the Lock light is on due to Error Code Display Mode being active, the dishwasher is in a diagnostic state and is not intended to run a normal wash cycle. You should exit the diagnostic mode before attempting to operate the appliance. The Lock indicator in this context does not indicate a physical hazard, but the unit should be returned to normal mode before use.
How much does it cost to repair a GE dishwasher showing the Lock indicator?
In most cases, the Lock indicator clears without any parts replacement once the correct button sequence is used to exit Error Code Display Mode, so the cost may be nothing beyond a service call fee if a technician is needed. If the issue points to a faulty control board that cannot exit diagnostic mode, control board replacement on a GE dishwasher typically costs between $150 and $400 depending on the model and labor rates in your area.
How do I fix the Lock indicator on my GE dishwasher?
Because the Lock indicator reflects that Consumer Error Mode is active, the fix involves exiting that mode using the appropriate control panel button sequence for your specific GE model. Once the mode is exited, the Lock light should turn off. If it remains lit after attempting to exit the mode, check whether another error code is also being displayed and address that underlying fault.
Will resetting my GE dishwasher clear the Lock indicator?
A power reset by disconnecting the dishwasher from power for several minutes may clear the Consumer Error Mode and turn off the Lock indicator. However, if the control board re-enters the diagnostic state after power is restored, there may be an underlying stored fault code or a control board issue that needs further diagnosis.
