Bosch Dishwasher SHI4306 overflowing

The Water Inlet Valve is an OEM part for Bosch dishwashers. This component is responsible for controlling the flow of water into the dishwasher. It operates via electrical signals from the dishwasher's control board, opening to allow water to enter during the filling phase and closing to halt water flow once the correct level is achieved.  

Causes for replacement can include wear and tear over time, mineral deposits from hard water that obstruct the valve, or electrical failures that prevent the valve from opening or closing properly.  

Symptoms of a bad Water Inlet Valve include:

• Insufficient water filling the dishwasher, leading to poor cleaning results.
• No water entering the dishwasher, resulting in dry cycles.
• Water leaking from the valve, which could indicate a crack or failure in the valve mechanism.

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

The Float Switch is an OEM replacement part specific to Bosch dishwashers. It is a switch located in the sump area of the dishwasher tub that detects water levels and provides feedback for automatic filling and draining functions.

Symptoms of a bad float switch include:

• The dishwasher fails to fully drain water after cycles
• Cycles not initiating or advancing properly due to water level issues
• Float switch area where the sensor attaches developing leaks
• Loose or detached float switch from normal wear over time

Causes of a bad float switch are usually mineral or sediment buildup disrupting its buoyancy and sensing ability. Without a properly functioning float switch, the dishwasher cannot effectively monitor water levels to manage filling and drainage.

This OEM Bosch replacement switch is also compatible with Thermador, Gaggenau, and some Kenmore dishwasher models.
