Bosch Dishwasher Float switch 611665

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishwasher does not fill with water when the float switch is falsely activated or defective.
• Dishwasher may run the drain pump continuously after the overflow-protection circuit detects water in the base.
• Water may collect beneath the dishwasher or an overflow-related fault may occur if the switch does not respond correctly.

Check Before Replacing

• Disconnect electrical power before inspecting the switch or accessing the dishwasher base.
• Check for standing water or evidence of a leak in the dishwasher base before condemning the switch; Bosch identifies water in the base as a cause of safety-switch activation.
• With power disconnected, verify that the float moves freely and is not obstructed by debris or misalignment.
• Inspect the switch wiring and connector for visible damage or looseness.
• If electrical testing is performed, follow the appliance service documentation for the specific model and use a qualified technician when access or live-voltage testing is required.
