Bosch Dishwasher SHX78CM2N Parts

This SMM programmed control module replaces a failed or unresponsive main control to restore normal appliance operation. It manages electronic functions and user interface signals so cycles start and run correctly. What it does:

• Acts as the appliance's main electronic control, coordinating wash/heating/drain cycles
• Interprets user inputs and sends commands to valves, pumps, and heaters
• Commonly used when the unit won't start, won't respond to controls, or shows electronic faults
• Helps resolve intermittent operation or communication errors between components

• Disconnect power at the breaker or unplug the appliance before servicing
• Handle the board by the edges and avoid electrostatic discharge (ESD) precautions
• Verify connector orientation and secure all wiring harnesses during reassembly

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.
