What FuS means on a GE dishwasher

The FuS error code indicates the control board has detected a critical failure in the circulation pump fuse circuit. This is a hard fault condition, meaning the board has identified an open or failed fuse protecting the circulation pump motor. Diagnostics should begin with a continuity check on the circulation pump fuse itself, followed by inspection of the circulation pump motor for shorts or mechanical failure that may have caused the fuse to blow. Reference the Failure to Drain Diagnostics and No Circulation and Drain section for the full diagnostic procedure.

For homeowners, this code means your dishwasher's main wash pump, the component responsible for spraying water through the spray arms during a cycle, has lost power due to a blown or failed fuse on the control board. This typically happens because the circulation pump motor drew too much current, either from a failing motor winding, a seized pump impeller, or a wiring fault that caused the protective fuse to open.

Because FuS is classified as a critical fault, the dishwasher will not complete a wash cycle. The underlying cause is almost always either a failed circulation pump motor or a shorted wiring harness, both of which require part replacement. A blown fuse alone does not fix itself; the root cause must be identified before any fuse or board component is replaced.

Common causes of FuS

  1. 01

    Failed circulation pump motor (shorted windings)

    Part replacement

    A shorted or grounded motor winding draws excessive current, which blows the circulation pump fuse on the control board. This is the most common reason the FuS code appears and must be ruled out before replacing any board components.

  2. 02

    Blown circulation pump fuse on the control board

    Part replacement

    The fuse protecting the circulation pump circuit on the control board may have opened due to a power surge or sustained overcurrent condition. A continuity test across the fuse will confirm whether it has failed, but the root cause of the overcurrent must also be resolved.

  3. 03

    Damaged or shorted wiring harness to the circulation pump

    Part replacement

    A pinched, chafed, or water-damaged wire in the harness between the control board and the circulation pump motor can create a short circuit that blows the board fuse. Inspect the harness along its full routing for visible damage or burn marks.

  4. 04

    Seized or obstructed pump impeller

    Wiring / connection

    A jammed impeller caused by broken glass, bone fragments, or debris forces the pump motor to stall and draw locked-rotor current, which can blow the circulation pump fuse. Inspecting and clearing the pump cavity may resolve the mechanical side of the fault.

Frequently asked questions about FuS

What does the FuS error code mean on a GE dishwasher?
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.
How do I fix the FuS error code on a GE dishwasher?
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.
Can I still use my GE dishwasher when it shows FuS?
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.
How much does it cost to repair a GE dishwasher with a FuS error code?
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.
Will replacing the control board fix a FuS error code on a GE dishwasher?
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.
