When an unbalanced condition occurs, the switch closes the circuit to the switch in the off-balance position. This removes electricity to all the washer's functional parts, stopping the cycle and thus avoiding a costly repair. The user then must redistribute the load more evenly in the washer tub, pull the timer dial out to de-energize the solenoid, and allow the switch to rest, and the push the timer dial in. This again closes the circuit to the normally active parts of the washer and washing machine.
