Bosch Dishwasher SHU4902SK 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
