GE Dishwasher Error Code HEAVY flashes

When the HEAVY light flashes on a GE dishwasher, it signals an overfill condition, meaning the pressure sensor or float switch has detected more water in the tub than the machine expects. The control board stops the wash cycle and activates the drain pump to remove the excess water. If the water level is not reduced within 60 seconds, the program halts completely. Common causes include a failed drain pump, blocked drain hose, faulty inlet valve, or a stuck float switch.

You should not continue running the dishwasher while this error is active. The flashing HEAVY light indicates the machine has already detected a water level it considers unsafe and has stopped the wash program to prevent overflow. Running it again without addressing the root cause risks water spilling onto your floor or into surrounding cabinetry. Resolve the underlying issue before resuming normal operation.

Repair costs vary depending on which component is at fault. A drain hose clearing or float switch cleaning may cost little to nothing if done yourself. Replacing a drain pump typically runs between $80 and $200 in parts and labor, while a new inlet valve or flow meter usually falls in the $60 to $150 range for parts alone. Adding professional labor costs can bring the total repair estimate to anywhere from $100 to $300 or more depending on the specific fault and your location.

Start by inspecting the drain hose for kinks or clogs and clear any blockages you find. Next, check the drain pump for debris or motor failure and confirm water is actually draining during the drain cycle. If the machine drains normally, the issue may be on the inlet side, specifically a water inlet valve that is not shutting off fully, or a faulty flow meter allowing too much water in. You should also check the float switch inside the tub for obstructions that could keep it in the raised position.

A reset may clear the error code temporarily and allow the dishwasher to restart, but it will not fix the underlying problem. If the cause of the overfill condition, such as a blocked drain, stuck float, or leaking inlet valve, has not been corrected, the HEAVY light will flash again during the next cycle. Address the root cause before relying on a reset to resume normal operation.
