  • The first step is to check the gate arm. The gate arm allows water to drain out of the dishwasher through the valve. The gate arm often has two springs attached to it, therefore if either spring is damaged or missing, it has to be replaced.
  • The second step is to check the solenoid. The solenoid is connected by two wires. Therefore disconnect the solenoid from the wires. Now test the solenoid for resistance using a multi-tester. Set the tester to the ohms setting X1. Place the tester probes on the terminals of the solenoid. The normal reading is 40 ohms. However, if the reading is significantly different, the solenoid will have to be replaced.
  • Next Give the motor a spin. This is the rotating blade inside the dishwasher. You can turn it by hand and allow water to drain.
