Bosch 00165256 Dishwasher Float Switch – 3-Terminal

Dishwasher Float Switch – 3-Terminal – Bosch

The Bosch 00165256 dishwasher float switch is a 3-terminal safety switch that detects the water level in the tub via a float. When the water reaches a set level, the float rises and opens or closes the switch to stop the water inlet valve and prevent overfilling. When the switch fails, the dishwasher may overfill, not fill at all, or trip the flood protection system. This direct-replacement 3-terminal float switch restores correct water level control on compatible Bosch dishwasher models.
