Our Bosch NEXT 300 washer cold water valve would occasionally stay open during the wash cycle. Unplugging the washer had no effect and the water would continue to run. Turning off the water supply to the washer would allow the valve to close. As the washer is 12 years old, I replaced the hot water valve along with the replacing the problematic cold water valve.
Removing two screws in the washer back allowed the washer top lid to be removed. Valve replacement was literally plug and play. Total repair time took 10 minutes.
The valves were an exact match. We have run 10 loads since valve(s) replacement and it is working flawlessly. Much cheaper than a new washer.
