Bosch Dishwasher Float switch (microswitch) 00165256, Replaces 165256

Genuine Bosch OEM dishwasher float switch/microswitch that senses an excessive water level and interrupts the water-fill circuit to help prevent overflow.

Is This the Right Part?

Common Symptoms

• Dishwasher will not fill with water.
• Dishwasher may overfill if the float switch fails to interrupt the fill circuit.
• Switch may stick, fail to activate, or provide inaccurate water-level readings.

Check Before Replacing

• With power disconnected, inspect the float mechanism and switch area for obstruction, sticking, or visible damage.
• If the dishwasher will not fill or overfills, verify the float can move freely and that the switch actuates as the float changes position.
• Use the appliance service documentation or a qualified technician for electrical continuity testing; do not rely on the symptom alone to condemn the switch.
