The Auxiliary Tool is an OEM part for Bosch dishwashers. This specialized tool is designed to assist with the removal and replacement of the metal nut found on the zeolite container or filter housing.

Proper maintenance such as routinely replacing the zeolite container is important for keeping a Bosch dishwasher operating at peak performance. The zeolite acts as a water softener that reduces water hardness and aids in the cleaning process. Over time, the zeolite container will need replacement as it collects soil and contaminants.

Causes of needing to replace the metal nut can include wear and tear from repeated container changes or damage that prevents the nut from sealing properly.

Symptoms of a bad nut include:

• Inability to securely tighten the zeolite container
• Leaks developing from the filter housing area
• Reduced cleaning ability due to hard water issues

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.
