  • 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.
