What the F55 error code actually means

Your dishwasher detected an electrical overload in the pump circuit, which caused a safety fuse on the control board to blow and shut down the pump to prevent damage. Think of it like a circuit breaker tripping to protect your home's wiring, except this fuse is built directly into the dishwasher's main control board. Until the underlying cause of the overload is found and the fuse or board is repaired, the pump will not receive power and the dishwasher cannot run a wash cycle.

Questions people ask about F55

What does the F55 error code mean on a GE dishwasher?
F55 means the pump fuse on the main control board has blown. The board detected an overcurrent condition in the pump circuit and the fuse opened to protect the board. The dishwasher will not operate until the fuse is replaced and the root cause of the overcurrent is identified.
Can I still use my GE dishwasher with an F55 error code active?
No. With F55 active, the pump fuse has blown and the pump circuit is non-functional. The dishwasher will not complete a wash cycle because neither the circulation pump nor the drain pump can receive power. Attempting to run the unit repeatedly without addressing the fuse will not clear the code.
Why does the fuse keep blowing after I replace it on my GE dishwasher showing F55?
If the replacement fuse blows again immediately during Service Mode testing, one of the pumps is defective and drawing excessive current. Test the circulation pump and drain pump separately in Service Mode to identify which one is causing the overcurrent. Replace the pump that triggers the fuse to blow. If neither pump causes the fuse to blow during testing but it still fails during normal operation, inspect the wiring harness to both pumps for shorts or damaged insulation.
How do I fix an F55 error code on my GE dishwasher?
Start by replacing the blown fuse in the fuse holder on the main control board. After replacing it, enter Service Mode and test the circulation pump and drain pump individually. If the new fuse holds during both tests, the repair is complete. If the fuse blows again during either pump test, that pump is drawing too much current and needs to be replaced.
How much does it cost to fix an F55 error code on a GE dishwasher?
If only the fuse needs replacement, the part cost is minimal, typically just a few dollars, though labor from a technician may add $75 to $150 depending on your area. If a pump is also faulty, a replacement circulation pump or drain pump for a GE dishwasher typically runs $40 to $120 for the part. DIY repair is feasible for anyone comfortable working with appliance wiring and accessing the main control board.
