The water inlet valve controls the flow of water into the dishwasher tub, and is solenoid- operated. The typical issues associated with water inlet valve failure are:
- The dishwasher will run, but no water will enter the dishwasher.
- The dishwasher will overfill and leak onto the floor.
- When the dishwasher is off, water still enters the tub.
- The dishes are not clean or not enough water enters the tub.
When dealing with these issues, perform the following steps:
- Verify the problem. Verify the problem by operating the dishwasher through its cycles. Listen carefully, and you will hear if the water is entering the dishwasher. On electronic models, turn off the electricity to the appliance and wait for two minutes before turning it back on. If a fault code appears, look up the code. If the dishwasher will not power up, locate the technical data sheet behind the control panel or under the tub of the dishwasher for diagnostics information. On some models, you will need the actual service manual for the model you are working on to properly diagnose the dishwasher. The service manual will assist you in properly placing the dishwasher in the service test mode for testing the dishwasher functions.
- Check for external factors. You should check for external factors not associated with the appliance. Is the appliance installed properly? Is the voltage supply correct for the dishwasher? Is the water turned on all the way? The voltage at the receptacle is between 108 volts and 132 volts during a load on the circuit. Do you have the correct polarity?
- Disconnect the power. Before working on the dishwasher, disconnect the power. This can be done by pulling the plug out of the wall receptacle. Be sure that you only remove the dishwasher plug. Double-check to ensure that the electrical supply has been disconnected before removing any service panels. Another way to disconnect the electricity is at the fuse panel or the circuit breaker panel. Turn off the electricity.

-
-
Using the ohmmeter, set the range on R × 1000, and place the probes on the solenoid coil terminals
-
The meter should read between 700- and 900-ohms resistance. If not, replace the water valve.
