Parts for Bosch SHXM4AY55N/01: Heat Pump / Water Inlet Parts

The Affresh Dishwasher Cleaner is an OEM accessory designed specifically for Whirlpool brand dishwashers. This citrus-scented tablet removes residue, odor-causing soils, and food particles from the dishwasher tub and gasket area during the cleaning cycle. Symptoms of a buildup include unwanted odors emanating from the dishwasher, especially after opening the door. Over time, residue and grime accumulate in hard-to-reach areas and provide an environment for mold and mildew growth.

Regular cleaning helps prevent this by removing leftover soils before they harden or encourage bacterial activity. The Affresh tablet utilizes a unique blend of cleaning ingredients that target soils and biofilms through a combination of powerful scrubbing action and natural cleaning enzymes.

As the #1 recommended dishwasher cleaner brand, Affresh is also compatible for use in Maytag, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and select Kenmore dishwashers for consistent cleanliness and freshness. The package includes six tablets 4.2 ounces

The Water Inlet Housing is an OEM component specifically designed for Bosch dishwashers.
