Water Inlet Valve:

The water inlet valve on your Bosch washing machine is used to fill the tub up with cold, warm or hot water for washing and rinse cycles.

If the Bosch washer does not stop filling, then the inlet valve is malfunctioning. If the Bosch washer does not fill, then the problem is related to the circuit of electricity that is controlling the valve.

How do you test the water inlet valve of the Bosch washing machines using a multimeter:

  1. Before you begin, shut off the water supply and power source from the Bosch washer.

  3. There are screens inside the valve that have become clogged with dirt and other particles. Clean up any debris or dirt that you find. The screens can’t be sold on their own and need to be replaced should they become damaged. Also, examine the exterior of the valve for cracks or wear and tear.
  4. Read the user’s manual to determine the resistance reading required for a functional valve varies between the various models of Bosch washer’s. Once you’ve reached the reading you want, switch the multimeter’s Rx1 setting to connect the terminals of the valve’s terminals. If the valve you’re using doesn’t have continuity, you can use the Bosch replacement valve.

It may also include an air dome tube, or hose, which connects the tub. On Bosch washers with electronic controls the switch could be located in the bottom of the sump, underneath the tub.

  3. Examine the switch and pipe for signs of cracking, fraying, wear or damage.
  4. If you find your switch is damaged, you need an Bosch replacement water level switch. In conclusion it is clear that an Bosch washing machine that drains and fills at the same time could be a frustrating problem to resolve If you have the right knowledge and tools the issue can be fixed.
