GE Dishwasher Error Code LED 1 — Stuck Relay on Control Board
What this means
When LED 1 flashes on a GE dishwasher control board (visible behind the front panel), it indicates a stuck relay on the main electronic control board. A relay is an electrical switch that the control board uses to turn components on and off. When a relay welds shut or fails to release, the component it controls (often the wash motor or heater) stays on continuously or does not turn on at all. This is almost always a control board failure.
Step-by-step fix
4 stepsPower cycle the dishwasher
Turn off the circuit breaker for the dishwasher for 5 minutes, then turn it back on. Start a wash cycle. If the LED 1 error clears and the dishwasher runs normally, it may have been a one-time glitch.
Power surges can cause relay contacts to temporarily weld. A reset sometimes breaks the contact free.
Access the control board
Unplug the dishwasher or turn off the breaker. Remove the inner door panel to access the main electronic control board. It is typically located behind the lower portion of the door.
Take a photo of all wire connections before removing anything so you can reassemble correctly.
Inspect the control board for visible damage
Look for burn marks, discolored components, or bulging capacitors on the board. A failed relay often shows darkening or burn marks on the solder joints around it.
If you see obvious burn damage on the board, replacement is the only reliable fix.
Replace the control board
Disconnect all wire harnesses from the old board, noting their positions. Remove the mounting screws, install the new board, reconnect all harnesses, and reassemble the door panel. Run a test cycle.
Handle the new board by its edges to avoid static discharge damage to the electronic components.
When to call a professional
Control board replacement involves working with the dishwasher's main electronics. If you are not comfortable identifying the correct board and reconnecting all wiring harnesses, have a professional handle this repair.
