Part TypeFloat Switch
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.
Pro Tip
A float-switch symptom does not prove the switch has failed: first check for an obstructed float, a disconnected connector, or water in the drip tray.
