GE Dishwasher Error Code FuS

FuS stands for a board circulation pump fuse failure. The control board detected that the fuse protecting the circulation pump motor circuit has opened or failed. The dishwasher cannot run a wash cycle with this fault active because the pump that circulates water through the spray arms has lost power at the board level.

No. FuS is classified as a critical fault, and the dishwasher will not complete a wash cycle because the circulation pump cannot receive power. Running the dishwasher in this state will not cause additional damage, but it will not clean dishes. The fault must be diagnosed and repaired before normal operation resumes.

Not necessarily, and replacing the board first is the wrong approach. If the circulation pump motor has shorted windings, installing a new board will blow the fuse on the replacement board as well. Always test the pump motor and wiring harness for faults before condemning the control board. The board itself is only replaced if it has a confirmed burned fuse or damaged trace and the pump and wiring test within normal specifications.

Start by checking continuity on the circulation pump fuse on the control board using a multimeter. If the fuse is open, do not replace it until you also test the circulation pump motor for shorted windings and inspect the wiring harness for damage. If the motor is shorted or seized, replace the motor first. Replacing the fuse without fixing the root cause will blow the new fuse immediately. GE's service documentation directs technicians to the Failure to Drain Diagnostics and No Circulation and Drain section for the full test sequence.

Cost depends on what failed. If only the circulation pump motor needs replacement, parts typically run between $80 and $160 depending on the model, plus one to two hours of labor if you hire a technician. If the control board also needs replacement due to a burned fuse trace or damaged board, parts can add $150 to $300 more. A DIY repair is feasible if you are comfortable with a multimeter and basic appliance disassembly, but the wiring and board diagnostics do require systematic testing rather than part swapping.
