When your Kenmore dishwasher won’t turn on, it is a huge inconvenience. The drive motor is a component that circulates the water within the machine. The electrical power to this motor comes through the timer or the electronic control via a start relay.
For example, if your LG dishwasher won’t turn on when the start relay powers the motor, the problem could be a faulty drive motor. Use a multi-meter to test the motor windings for continuity. If there’s a hum originating from the motor, it could be a sign of a seized motor, which needs replacement.
It is a simple enough repair when a Samsung dishwasher won’t turn on due to a fuse problem. You will find the thermal fuse on the top of the circuit board assembly, usually with two wires attached to it. Remove the inner door to access the fuse and disconnect these two wires.
The selector switch allows you to choose individual wash cycles, like heated dry or Eco wash. The switch can be used in the motor or fill circuit, and when it is faulty, your GE dishwasher won’t turn on.
