Bosch Dishwasher SGS45M42II Parts

This drain pump assembly is responsible for expelling used water from the dishwasher tub during the drain cycle. It uses an impeller driven by a small motor to push water out through the drain hose. Replace this pump if the dishwasher fails to drain, leaves standing water at the bottom of the tub after a cycle, or if you hear the pump motor buzzing or humming without actually draining.

This is a small insert or overlay that fits into the dishwasher rack, functioning as a flip tine to help hold dishes, cups, or other items securely in place during the wash cycle. It clips or snaps into the rack assembly. Replace this part if it has broken, cracked, or gone missing, causing items to shift or fall over during washing.

Connection piece for dishwasher installation. Replace this component if your original is cracked, broken, or missing to ensure proper connections.

This insulating part helps reduce heat transfer and protects nearby components from high temperatures, improving appliance safety and longevity. Use it to replace a damaged or missing thermal insulator that can allow heat damage or arcing. What it does:

• Provides thermal insulation to keep heat away from wiring, plastic, and sensitive parts
• Helps prevent heat-related damage and reduces risk of component failure
• Reduces heat-related odors or smoking usually caused by failing insulation
• Restores proper spacing and protection around heating elements or hot assemblies

• High-level replacement only; verify exact location and orientation before removing old part
• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Handle carefully to avoid deforming the insulator; ensure it does not contact moving parts

This turbidity sensor detects how clear the dishwasher's wash water is so the control can adjust cycle time, rinses, and water changes. Replacing a faulty sensor helps restore proper cleaning performance and normal cycle lengths.

• Monitors soil level/clarity of the wash water
• Signals the control to extend or shorten wash and rinse phases as needed
• Helps optimize water use while maintaining cleaning results
• Failure symptoms can include unusually long or short cycles, poor cleaning, repeated draining/refilling, or cycles that won't advance

• Disconnect power and turn off the water supply before servicing
• Pull the dishwasher out as needed; access the sensor from the base area
• Place a towel to catch residual water; release the locking tab or twist-lock, unplug the connector, and install the new sensor fully seated and locked
• Restore power/water and run a test cycle; check for leaks
