Kitchenaid Dishwasher KDTM404EBS0 Not cleaning dishes properly

The Turbidity Sensor is an OEM part for Whirlpool dishwashers. It detects the level of particles in the water during the wash cycle, allowing the dishwasher to adjust the cycle duration and water usage for optimal cleaning performance. This sensor ensures that dishes are thoroughly cleaned by monitoring water clarity.

You should replace the turbidity sensor if it becomes faulty or damaged. Causes of a bad turbidity sensor can include regular wear and tear, exposure to hard water minerals, or electrical malfunctions. A malfunctioning sensor can lead to inefficient cleaning cycles and poor wash results.

Symptoms of a bad turbidity sensor include:

• Dishes not being cleaned properly
• Dishwasher running longer than usual or shorter cycles
• Error codes related to the sensor
• Inconsistent wash performance

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

The Retainer is an OEM replacement part for Whirlpool built-in dishwashers. It is a plastic clip located within the lower wash arm assembly. This retainer securely holds the pivot hub bearing and ensures smooth oscillation of the lower wash arm during cycles.  

Causes of retainer failure commonly relate to plastic material degradation from regular heat and chemical exposures over many uses. Crack propagation weakens the clips ability to precisely position bearing elements.

Symptoms of an inadequate retainer may include:

• Grinding or scraping noises coming from the wash arm area
• Restricted movement or binding of the lower spray arm assembly
• Potential loose wash arm parts that could interrupt spray patterns  

This OEM Whirlpool replacement is also compatible with KitchenAid, Maytag, and some Sears/Kenmore dishwashers.
