GE Dishwasher Error Code HEAVY

On a GE dishwasher, HEAVY as an error code indicates an overfill condition, meaning the machine detected more water in the tub than the control system allows. The pressure sensor or float switch triggered an alert, and the dishwasher attempted to drain the excess water. If the water did not drain within 60 seconds, the wash program stopped automatically to prevent an overflow situation.

No, it is not safe to continue running the dishwasher until the underlying cause is identified and corrected. The HEAVY code indicates a potential overfill condition, and if the drain system is unable to clear excess water, the machine could overflow onto your floor. Shut the dishwasher off and investigate the drain system and water inlet before running another cycle.

Repair costs depend heavily on which component has failed. A drain hose cleaning or float switch adjustment may cost little to nothing if done yourself. Replacing a drain pump typically runs in the range of $100 to $250 in parts and labor, while a new inlet valve or flow meter can add $75 to $200 depending on the part and service rates in your area. Getting a diagnosis from a qualified technician before purchasing parts is recommended to avoid unnecessary expense.

Start by checking the drain hose for kinks or clogs and inspect the drain pump filter for debris. If the drain path is clear, check whether water is pooling in the tub when the machine is off, which would point to a leaking inlet valve. You should also inspect the float switch under the tub floor to make sure it moves freely and is not stuck in the raised position. If basic checks do not resolve the issue, testing the drain pump motor and pressure sensor with a multimeter may be necessary.

A reset may temporarily clear the error display, but it will not resolve the underlying problem. If the cause, such as a blocked drain hose, a stuck float switch, or a faulty inlet valve, is still present, the HEAVY code will return during the next cycle. Always diagnose and correct the root cause before relying on a reset.
