GE Dishwasher Error Code Overfill

The Overfill error means the dishwasher detected that water reached an unsafe level inside the tub or leaked into the base of the unit. This is indicated by the second-level pressure switch activating or the under-sump leak detection switch closing. The dishwasher shuts down automatically to prevent water damage to your home. The underlying cause can range from a stuck inlet valve to an actual water leak beneath the tub.

No, you should not continue running the dishwasher until the cause is identified. The Overfill condition indicates either an uncontrolled fill or an active water leak, both of which can cause significant water damage to cabinetry and flooring. The dishwasher's automatic shutoff is a safety feature, and bypassing it without resolving the root cause is not recommended.

Repair costs vary depending on which component is at fault. A water inlet solenoid valve typically costs between $25 and $75 for the part, while a pressure switch can range from $20 to $60. If professional labor is needed, expect to add $100 to $200 for a service visit depending on your area. If the cause is simply a fill time adjustment or a stuck switch float with no parts needed, the cost can be minimal.

Some causes are DIY-friendly, such as adjusting the fill time setting or clearing debris from around the under-sump switch. However, replacing the water inlet solenoid valve or the second-level pressure switch requires comfort working with water supply connections and basic electrical testing. If you find standing water in the base of the dishwasher, dry it out completely before attempting any diagnostics.

Resetting the dishwasher may temporarily clear the error code, but if the underlying issue is not corrected, the fault will return as soon as the problematic component is active again during the next cycle. A reset is useful for confirming whether the fault is intermittent or persistent, but it is not a repair. Address the inlet valve, pressure switch, or under-sump switch before relying on a reset.
