What F6 means on a GE dishwasher

The F6 error code on a GE dishwasher indicates that water has been detected in the floor protect pan, which is the drip tray located at the base of the unit beneath the wash tub. This pan is designed as a safety containment system to catch any water that escapes the primary tub assembly. A float switch or water sensor sits inside this pan, and when water accumulates to a detectable level, the switch triggers the F6 fault to alert the user and halt normal operation.

The most common source of water in the floor protect pan is a leak originating from internal components such as the door gasket, pump assembly, water inlet valve, hose connections, or the tub itself. Even a slow drip over multiple wash cycles can eventually accumulate enough water to trigger the sensor. Because the pan is enclosed beneath the dishwasher, leaks can go unnoticed until the F6 code appears.

Diagnosing this error requires physically inspecting the floor protect pan for standing water and tracing the source of the leak. The dishwasher should be powered off and, if safe to do so, carefully pulled forward to allow access to the underside. Technicians should inspect all hose clamps, the pump housing, the inlet valve connection, and the door seal for signs of moisture, cracking, or mineral buildup that could indicate a slow leak path.

Common causes of F6

  1. 01

    Faulty or worn door gasket

    Part replacement

    A degraded or improperly seated door gasket allows water to escape around the door during the wash cycle. Look for moisture along the bottom edge of the door or visible cracking and flattening of the rubber seal.

  2. 02

    Leaking water inlet valve

    Part replacement

    The water inlet valve can develop cracks or loose fittings that allow water to drip into the base pan. Inspect the valve and its connected hose for signs of moisture or mineral deposits indicating a slow leak.

  3. 03

    Pump or pump housing leak

    Part replacement

    The wash pump or drain pump housing can develop cracks or loose seals over time, allowing water to escape into the base. Water pooling directly below the pump area is a key indicator.

  4. 04

    Loose or damaged hose connections

    Wiring / connection

    Hose clamps connecting the pump, inlet valve, or spray arm supply lines can loosen or corrode, creating drip points. Check all visible hose connections for wetness or white mineral residue.

  5. 05

    Condensation or overfilling

    Wiring / connection

    Excessive detergent causing over-sudsing or a malfunctioning water level sensor leading to overfilling can push water past the tub into the base pan. This may occur without a physical leak in any component.

Frequently asked questions about F6

What does F6 mean on a GE dishwasher?
The F6 code on a GE dishwasher means water has been detected in the floor protect pan, the containment tray at the base of the appliance. A sensor or float switch inside this pan triggers the code when water accumulates there. This indicates a leak somewhere within the dishwasher's internal plumbing or door sealing system. The machine halts operation to prevent further water from escaping onto your floor.
Can I fix the F6 error on my GE dishwasher myself?
Some causes of the F6 error are DIY-friendly, such as tightening a loose hose clamp or replacing a door gasket. However, repairing a cracked pump housing or a failed inlet valve requires more technical skill and component replacement. It is important to first identify and dry out the floor protect pan and locate the source of the leak before attempting any repair. If you are not comfortable accessing the underside of the appliance, a qualified technician should perform the inspection.
Is it safe to use my GE dishwasher when the F6 code is showing?
No, you should not run the dishwasher while the F6 code is active. The error indicates water is already present in the base pan, and continuing to operate the unit could worsen the leak and cause water damage to your floor or cabinetry. Power off the dishwasher and allow it to dry before investigating the source of the leak.
Will resetting my GE dishwasher clear the F6 error?
Resetting the dishwasher may temporarily clear the F6 code, but the error will return if the underlying leak has not been repaired. The floor protect pan sensor will trigger the fault again as soon as water re-enters the pan. Clearing the code without fixing the leak does not resolve the problem and risks ongoing water damage.
How much does it cost to repair a GE dishwasher F6 error?
Repair costs vary depending on the root cause. Replacing a door gasket is typically a lower-cost repair, often in the range of $20 to $80 for parts, while a water inlet valve or pump replacement can cost between $80 and $250 or more including labor. A professional diagnostic visit to identify the leak source generally runs $75 to $150 before any parts are factored in.
