Whirlpool Dishwasher Float Switch W11255994 – Superseded by W11545764

OEM dishwasher float switch used to monitor water level and help prevent overfilling. The part is documented in Whirlpool dishwasher repair-parts lists as a float switch.

Is This the Right Part?

Common Symptoms

• No fill or low water because the control detects an open overfill switch
• Dishwasher fills and then drains when the float switch circuit is activated or disconnected
• Overfill-related fault indication or interrupted filling cycle
• Possible overfilling if the switch fails to open when the float rises

Check Before Replacing

• Disconnect electrical power before inspecting the float-switch area or wiring.
• Verify that the dishwasher float moves freely and is not obstructed; Whirlpool technical information indicates the switch should actuate with the float movement.
• Inspect the float-switch connector and harness for looseness, visible damage, or disconnection; reconnect only with power disconnected.
• If qualified to use an ohmmeter, test the switch only with power disconnected: the switch should show continuity in the normal float-down position and an open circuit when the float is raised, according to Whirlpool service documentation.
• Check whether water is present in the dishwasher drip tray, since a filled tray can activate the float-switch protection circuit. Do not assume the switch itself is defective until the float, tray, wiring, and related fill components have been checked.
