Common Symptoms
- Washer will not start
- Cycles stop unexpectedly
- Washer functions such as filling, washing, draining, or spinning fail
- Control buttons or settings may not respond correctly
- Washer may display abnormal operation associated with failed electronic control
Check Before Replacing
- Confirm the washer model number before ordering because this board is model-specific.
- With power disconnected, inspect the existing board and wiring connectors for visible damage, burnt areas, or loose connections.
- Verify that the part number on the existing board matches EBR86771812 before replacement.
- Do not condemn the board solely from a no-start symptom; check related wiring and connected components first.
Pro Tip
Match both the exact board number and the washer model; model-number similarity alone does not establish compatibility.
