Blown pump fuse on main control board.

GE codesGE dishwasher codes

Blown pump fuse on main control board.

First step from the service manual

Replace fuse in fuse holder located on main control board. In Service Mode, operate the circulation pump and then drain pump to test. If fuse blows again when testing either pump, replace the faulty pump.

What F55 means on a GE dishwasher

The F55 error code indicates that the pump fuse on the main control board has blown. This fuse protects the control board's pump circuit from overcurrent events. The board detected a fault severe enough to open the fuse, cutting power to the pump circuit to prevent further damage. The fuse is housed in a dedicated fuse holder directly on the main control board.

For homeowners, this means your dishwasher's control board detected too much electrical current flowing through the pump circuit and a small protective fuse burned out to stop the damage. The dishwasher will not run until this fuse is replaced. The fuse itself is inexpensive, but if either the circulation pump or drain pump caused the overcurrent condition, replacing just the fuse will result in it blowing again immediately during testing.

The key diagnostic step is to replace the fuse first, then test each pump individually in Service Mode. If the fuse holds through both pump tests, the board is likely fine. If it blows again during circulation pump or drain pump operation, that pump is drawing excessive current and needs to be replaced.

Common causes of F55

  1. 01

    Blown fuse on main control board

    Part replacement

    The fuse in the fuse holder on the main control board has opened due to an overcurrent event. This is the immediate cause of the F55 code and must be addressed before any further diagnosis can proceed.

  2. 02

    Faulty circulation pump drawing excessive current

    Part replacement

    A failing circulation pump motor can develop an internal short or mechanical binding that causes it to draw more current than the fuse is rated for, blowing the fuse. This is confirmed when the fuse blows again during circulation pump testing in Service Mode.

  3. 03

    Faulty drain pump drawing excessive current

    Part replacement

    A shorted or seized drain pump motor can similarly pull excessive current through the pump circuit, blowing the fuse. This is confirmed when the replacement fuse blows during drain pump testing in Service Mode.

  4. 04

    Damaged wiring or short in pump wiring harness

    Part replacement

    A chafed, pinched, or shorted wire in the harness connecting either pump to the control board can create a direct overcurrent path that blows the fuse even when the pump motor itself is intact.

Frequently asked questions 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.
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.
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.
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.
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.
