Thermador Dishwasher Switch

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.

The On/Off Switch is an OEM part for Bosch dishwashers. It provides the function of powering the unit on or off with the press of a button.

Causes can be normal wear over thousands of cycles or moisture damage compromising electronics. Physical impact could also affect switch operation over time.

Symptoms of a bad on/off switch include:

• The dishwasher failing to start wash cycles when the switch is engaged
• Washers inadvertently stopping mid-cycle or short cycling irregularly
• The control panel lighting/interface malfunctioning or unresponsive

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

The Pressure Chamber is an OEM part for Bosch dishwashers. This part is responsible for monitoring and controlling the water level within the dishwasher. It operates by sensing the pressure exerted by the height of the water in the tub and ensures that the dishwasher fills with the correct amount of water for optimal cleaning performance.

Causes for replacement may involve wear and tear over extended use, mineral buildup affecting the switch’s sensitivity, or electrical faults leading to inconsistent performance.  

Symptoms of a failing Pressure Chamber include:

• Overfilling or underfilling of the dishwasher, which can lead to inadequate cleaning or potential water damage.
• Unexpected changes in the wash cycle, such as sudden stops or pauses.
• The dishwasher not starting a wash cycle due to incorrect water level readings.

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

An integrated door switch for dishwashers that senses when the door is closed and allows the machine to start. Replacing a worn or damaged switch restores normal operation and helps prevent cycles from running with an open door. What it does:

• Detects door-closed position and tells the control board the door is secure
• Enables the dishwasher to start cycles only when the door is properly latched
• Prevents operation or pauses cycles if the door is open or not fully closed
• Common symptom: dishwasher won't start or stops mid-cycle when the door is opened

• Disconnect power to the appliance before attempting any service.
• Access typically requires removing the inner door panel or toe-kick; handle the door carefully to avoid damage.
• Replace the switch and reconnect wiring exactly as removed; ensure connectors are fully seated.
• After installation, restore power and ensure the door registers closed and the unit starts normally.

A reed switch door sensor that detects when the appliance door is closed so the control can start cycles. Replaces a failed magnetic sensor to restore reliable door-closed detection and normal operation. What it does

• Acts as a magnetic contact that signals the control when the door or lid is closed
• Helps prevent the appliance from starting if the door is open or not fully latched
• Common symptom fix for no-start, intermittent cycle start, or control not recognizing a closed door
• Works as the electrical switching element in the door/detector assembly

• One reed switch (single replacement sensor)

• Disconnect power to the appliance before replacing the part to avoid shock or damage
• Handle the switch and wiring gently; avoid bending or stressing terminals and solder joints
• Locate and access the door/detector area per your service manual or tech sheet; confirm connector orientation before installing

This door switch completes the circuit when a door or access panel closes, allowing normal operation and preventing the appliance from running with the door open. Replaces a worn or failed door-interlock switch to restore reliable door sensing. What it does:

• Detects when the door is closed and signals the appliance control to enable operation
• Prevents runs or cycles when the door is open for safe operation
• Commonly replaced when the appliance won't start or the door fails to register as closed
• Works as the electrical contact point in the door latch/sensing system

• Disconnect power before servicing to avoid shock or injury
• Access may require removing the door panel or control bezel depending on model
• Handle the switch and connectors carefully to avoid bending terminals
