00165256 Bosch 3 Terminal Float Switch

The 3 Terminal Float Switch is a genuine OEM replacement part designed for Bosch dishwashers, and is also compatible with Thermador, Gaggenau, and select Kenmore models. Located in the sump area of the dishwasher, this switch is crucial for detecting water levels and controlling the automatic water fill and drainage functions.

Common indicators of a malfunctioning float switch include:

- Incomplete drainage of water post-cycle
- Interruptions or failures in cycle initiation or progression due to issues with water levels
- Leakage around the area where the sensor is attached
- The float switch becoming loose or detaching due to regular usage

The primary reason for float switch failure often relates to mineral or sediment accumulation, which can hinder its buoyancy and ability to sense accurately. A malfunctioning float switch impairs the dishwasher's ability to regulate water levels effectively, which is essential for its operation.

Replacing a faulty float switch can resolve issues such as overflowing and the inability to fill with water.
