What F201 means on a GE dishwasher

The F201 error code on a GE dishwasher indicates that the flood switch has triggered or failed during the appliance's self-diagnostic routine. The flood switch is a safety component located in the base pan of the dishwasher, designed to detect water that has leaked out of the wash tub and accumulated beneath the unit. When the control board runs diagnostics at startup or during a cycle, it checks the state of this switch. If the switch reports an active fault condition, the dishwasher halts operation and displays F201 to prevent potential water damage.

The diagnostic approach branches based on whether water is actually present in the tub. If water is found standing in the tub, the priority is to investigate the drain system, as a failed drain pump, clogged drain hose, or blocked filter assembly may have caused overflow or backflow conditions that triggered the switch. The control board interprets the flood switch signal and cannot distinguish between a genuine flood event and a faulty switch without further investigation.

If the tub is dry and no standing water is detected in the base pan either, the flood switch itself is most likely defective. In this scenario, the switch is either stuck in a closed position or has an internal electrical fault that mimics a flood condition to the control board. Replacing the flood switch is the corrective action when no actual water intrusion is present. Left unaddressed, this fault will prevent normal dishwasher operation regardless of whether a true leak exists.

Common causes of F201

  1. 01

    Faulty or stuck flood switch

    Part replacement

    The flood switch may have failed internally, causing it to report a flood condition even when the base pan is dry. This is the most common cause when no water is found in the tub or beneath the unit.

  2. 02

    Drain system failure causing standing water

    Wiring / connection

    A failed drain pump, kinked drain hose, or clogged filter can prevent the tub from draining properly, leading to overflow that activates the flood switch. Check for standing water in the tub and inspect the drain path.

  3. 03

    Water leak from internal components

    Part replacement

    A leaking door seal, pump seal, or hose fitting can allow water to escape into the base pan and physically trigger the flood switch. Inspect the base pan for visible moisture after removing the lower kickplate.

  4. 04

    Wiring harness issue to flood switch

    Wiring / connection

    A damaged, corroded, or disconnected wire between the flood switch and the control board can cause the board to read a false fault signal. Inspect the connector and wiring at the switch for damage or corrosion.

Frequently asked questions about F201

What does F201 mean on a GE dishwasher?
F201 indicates that the dishwasher's flood switch has been triggered or has failed during self-diagnostics. The flood switch is a safety sensor in the base of the unit that detects water leaking out of the wash tub. The dishwasher stops operation when this fault is detected to prevent water damage. The cause may be a drainage problem, an actual leak, or a defective switch.
How do I fix the F201 error on my GE dishwasher?
Start by checking whether there is standing water in the tub. If water is present, investigate the drain pump, drain hose, and filter for blockages or failures. If the tub is dry, remove the lower kickplate and check the base pan for moisture. If the base pan is also dry and no leak source is found, the flood switch itself should be replaced.
Is it safe to use my GE dishwasher with an F201 error?
You should not run the dishwasher until the cause of the F201 error has been identified and resolved. The fault may indicate an active water leak underneath the unit, which can cause damage to flooring and cabinetry. Even if the switch is simply faulty, operating the dishwasher without investigating the source of the signal is not recommended.
Will resetting my GE dishwasher clear the F201 error?
A reset may temporarily clear the error code, but F201 will return if the underlying problem has not been corrected. If the flood switch is defective or water is present in the base pan, the control board will detect the fault again during its next diagnostic check. Resetting without repair is not a lasting solution.
How much does it cost to repair a GE dishwasher F201 error?
If only the flood switch requires replacement, parts and labor typically range from around $75 to $175 depending on your location and service provider. If the root cause is a failed drain pump or a leaking door seal, repair costs can range from $100 to $300 or more. Diagnosing the exact cause before ordering parts helps avoid unnecessary expense.
