Bosch SHP65CM5N 24 in 500 Series Pocket Handle 44 dBA E18 Error Fix: Inlet Valve Not Closing Properly

The water inlet valve is not closing properly after a fill cycle. Water continues to enter the dishwasher after the control has commanded the valve to close. This will eventually cause an overfill condition. The inlet valve diaphragm may be worn or contaminated with debris that prevents full closure. Replace the water inlet valve assembly. As a temporary measure, turn off the water supply valve under the sink when the dishwasher is not in use.
