Frigidaire Washer Error Code E55

E55 indicates a motor sensing failure at the main control board, meaning the board cannot properly monitor the motor's operation. The fault is identified as originating within the board itself, not in the motor or external wiring. Frigidaire's diagnostic guidance treats the main board as defective when this code appears.

A reset will not permanently clear E55 because the fault is caused by a defective component on the main board, not a temporary software glitch. The code will return as soon as the washer attempts to run the motor again. The only resolution is replacing the main control board.

The cost depends on whether you replace the board yourself or hire a technician. A replacement main control board for a Frigidaire washer typically costs in the range of $100 to $250 for the part alone. If you use a repair service, labor charges will add roughly $75 to $150 on top of the part cost, depending on your area.

A knowledgeable DIYer can replace the main control board, which is the required fix for E55. Before ordering a board, check that all wiring harness connectors to the existing board are fully seated, as a loose connection can sometimes produce this fault. If connections are secure and the code persists, the board needs to be replaced.

You should not continue using the washer while E55 is active. The board cannot properly monitor the motor, which means the machine lacks the feedback it needs to operate safely and within normal parameters. Running the washer in this condition risks further component damage.
