Solenoid valve controls the appliance's water inlet using an electrically actuated plunger to open and close flow. Replacing a failing valve helps restore proper filling and can stop leaks, overfilling, or no-fill conditions. What it does

• Electrically opens and closes the inlet to allow water into the appliance during fill cycles.
• Shuts off water flow when the valve is de-energized to prevent overfilling.
• Common symptom fixes: no water fill, continuous filling, visible leaks at the inlet, or related fill/flood error codes.
• Interfaces with the appliance inlet hose and the electrical connector for timed/controlled fill cycles.

• One solenoid valve.

• Disconnect power and shut off the water supply before starting any repair.
• Handle electrical connectors carefully; ensure correct orientation and a secure connection.
• Inspect and replace any worn seals, gaskets, or hoses to prevent leaks after installation.

This push-on retainer clip holds a 6mm shaft securely in place on compatible appliance components, restoring proper axial restraint and preventing parts from sliding off during operation. Simple, low-profile fastening for shaft retainment. What it does:

• Secures shafts and spindles with a 6mm outer diameter to prevent axial movement
• Keeps knobs, pulleys, or rotating components positioned correctly during use
• Commonly used where a quick, tool-free clip is required for retention
• Can resolve symptoms like loose or detached knobs, wobbling pulleys, or parts sliding along the shaft

• One push-on retainer clip sized for 6mm shaft mounting

• Push the clip onto the shaft groove until it snaps into place; ensure full engagement before operating
• Use snap-ring pliers or appropriate tools if removal is required to avoid damage
• Wear eye protection when installing or removing clips to guard against sudden release

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.

Replacement potentiometer that restores precise control of appliance settings by regulating resistance in the control circuit. Use it when a rotary control is unresponsive or produces inconsistent settings for reliable operation. What it does:

• Varies electrical resistance to adjust settings controlled by the knob (e.g., temperature, speed, or level)
• Replaces a worn or faulty rotary control that causes unresponsive or erratic behavior
• Helps restore smooth, predictable adjustment when the original control no longer responds properly
• Fits into the existing control assembly to restore user input accuracy

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Access the control panel or module to remove the old potentiometer; note knob/shaft orientation and wiring
• Match wire connections and mounting position of the replacement part; test operation before reassembling the panel
