Bosch 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 Spark Switch is an OEM part for Bosch ranges. This part ignites the burners by sending a signal to the spark module, which then produces the spark needed to ignite the gas.  

Causes of a bad spark switch can include wear and tear from regular use, damage from spills or cleaning agents, or electrical issues.  

Symptoms of a bad spark switch include:

• Burners not igniting
  Continuous clicking even after the knob is turned off
  No spark when attempting to ignite the burner
  The cooktop not producing a flame

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

The Float Switch is an OEM part for Bosch dishwashers. This part monitors the water level inside the dishwasher. It helps prevent overflows by detecting when the water level gets too high and signaling the control board to stop filling and start draining the water.

Causes of a bad float switch can include wear and tear from regular use, buildup of debris or mineral deposits, or electrical malfunctions.  

Symptoms of a bad float switch include:

• The dishwasher not filling with water
• Water overflowing from the dishwasher
• The dishwasher not advancing through the cycles
• Error codes related to water level issues

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore 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 Sensor is an OEM replacement part for Bosch dishwashers. It detects soil levels through cycles, automatically adjusting water volumes and times for optimal cleaning. Precise sensing reduces overwashing.

Causes of a bad sensor involve general deterioration from continuous usage monitoring wash parameters thousands of times. Dirt or debris accumulation triggers false readings, decreasing efficiency.

Symptoms of a bad sensor include:

• Extended cycle times as improper inputs cause system delays  
• Inconsistent wash results relying on default static cycle settings
• Error codes displayed indicating disrupted functionality
• Soiled dishes from inadequate adjustments meant for heavier loads 

This OEM Bosch part maintains customized cleaning for Thermador versions as well.

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 water level regulator controls the appliance's water fill by sensing and regulating pressure/level for proper operation. Replacing a failing regulator restores correct fill behavior and helps prevent over- or under-fill conditions. What it does:

• Senses water level/pressure and signals the fill system to start or stop water flow
• Prevents overfilling by stopping the inlet when the correct level is reached
• Helps avoid underfilling that can cause poor wash or rinse performance
• Resolves symptoms like continuous filling, no fill, or erratic water levels

• Water level regulator

• Disconnect power and turn off the water supply before attempting replacement
• Handle electrical connections and hoses carefully; note wiring positions for reassembly
• Inspect hoses and seals for damage and replace if cracked or brittle
• Test the appliance through a short cycle after installation to ensure proper fill and operation
