Electrolux Dishwasher Error Code i50 — Wash Motor Triac Failure
What this means
The i50 error code on Electrolux dishwashers indicates the triac (electronic switch) that controls the wash motor on the main control board has short-circuited or failed open. This means the control board can no longer properly control the wash pump motor. The dishwasher may not wash at all, or the motor may run continuously without control. This is primarily a control board failure.
Alternate codes: I50, i 50
Step-by-step fix
4 stepsPower cycle the dishwasher
Turn off the dishwasher at the circuit breaker for 10 minutes, then turn it back on. Try running a cycle. Occasionally, a momentary glitch can trigger this code.
If the motor runs non-stop (even with the door open), turn off the breaker immediately — the triac is shorted closed.
Check the wash motor connections
Remove the lower access panel and locate the wash motor. Check all wire connections to the motor for loose or burnt connectors. A loose connection can cause the triac to overheat and fail.
Burn marks on wire connectors indicate arcing — replace damaged connectors with proper crimp terminals.
Test the wash motor
Disconnect the wash motor wiring and test the motor windings for continuity and for shorts to ground. A shorted motor can blow the triac on the control board.
If the motor is shorted, replace it before installing a new control board to prevent immediate re-failure.
Replace the control board
If the motor tests fine, replace the main control board. The triac cannot be replaced individually — the entire board must be swapped. Transfer all wire connections carefully.
Take clear photos of all connections before removing the old board.
When to call a professional
Control board replacement in a dishwasher is moderately complex. If you're not comfortable with electrical work, call a professional.
