Signs
Symptoms you may notice
Performance depends on which circuit generated the fault.
The code can be intermittent or repeat at the same cycle stage.
The appliance may pause, stop, or disable the affected function.
The control may prevent operation until the condition is cleared.
Why it happens
Possible causes
An abnormal operating condition logged by the control.
A loose or damaged connector or wire harness.
An electronic-control fault after the related circuit is checked.
A component in the affected circuit that is not responding as expected.
A mechanical condition that keeps the expected operation from completing.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Do not remove internal panels simply to clear the display; a repeat fault should be diagnosed in its circuit.
Record exactly when the code appears and whether it follows power-up, filling, heating, motion, draining, or shutdown.
Use one normal restart only if the appliance is safe to energize.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
