Washer: Won't start
If the washer is getting power but doesn't start, the switch that senses whether the lid or door is shut or locked might have failed. A failed timer, main electronic control board, user interface board or motor control board can also prevent the washer from starting.
Washers with an electronic control system often signal an error code on the display when the washer won't start. If your washer display signals a code, use our washer error code charts to determine the cause of the code and fix the problem.
Vertical modular top-load washers signal a component problem in a unique way. This type of top-load washer locks the lid during the cycle because it spins the basket at a high rate of speed in the spin mode. A vertical modular top-load washer flashes the Lid Lock light instead of a code when the washer won't start. This video shows how to troubleshoot flashing lid lock errors on a vertical modular washer.
A top-load, direct-drive washer uses an electro-mechanical timer to control washer functions, so it won't signal error codes. This type of washer doesn't lock the lid because it spins the basket at lower speeds than a vertical modular top-load washer. Instead, the direct-drive, top-load washer stops if you lift the lid. The wash cycle won't start if the direct-drive washer doesn't fill or the water-level pressure switch doesn't detect that the washer filled. This video shows how to troubleshoot a top-load, direct-drive washer that won't fill. As shown in the video, a failed water inlet valve assembly or bad water-level pressure switch can prevent a direct-drive, top-load washer from starting.
Replace the washer door lock assembly
The door lock assembly on a front-load washer includes a safety switch that detects whether the washer door is closed, a latch and a locking mechanism. If any of these components fails when the door is open, the door won't lock; if a component fails with the door is closed, the door won't open. Replace the entire assembly if any component fails.
Replace the washer main control board
The main electronic control board, also called the mother board, governs the timing and execution of the washer component functions. It controls the fill valves, the drive motor and the drain pump.
Replace the washer lid switch
The lid switch on a top-load washer is a safety switch that detects whether the washer lid is closed. The lid must be closed when the basket spins; some top-load models require that the washer lid be closed before the washer drive motor runs. An open lid prevents some top-load washers from filling. If the lid switch isn't detecting whether the lid is closed, replace the switch.
Replace the washer motor control board
The motor control board is a circuit-control board in a front-load washer that's usually in the bottom of the washer next to the drive motor. It monitors and controls the drive motor speed and direction for the tumble and spin actions during the cycle. If the motor doesn't run, the motor control board might need to be replaced.
Replace the washer timer
The timer controls the component functions in the washer. Also called a cycle selector, the timer has a motor that advances the internal cams inside the timer body. The cams open and close electrical contacts to energize and de-energize components during the wash cycle. A control knob on the stem of the timer lets the user select cycles on the timer. If the timer motor does not advance or the contacts are defective in the timer, replace it.
Replace the washer user interface board
The user interface board holds the buttons you press to set up the wash cycle. Replace the user interface board if one or more of the buttons don't work.
Replace the washer water inlet valve assembly
The water inlet valve assembly is a set of electrically operated water valves that control the fill function in the washer. Replace the water valve assembly if the washer won't fill because a valve doesn't open or if the washer overfills because the valve doesn't close.
Replace the washer water-level pressure switch
The water-level pressure switch detects the water level in the wash tub. If the water-level pressure switch is defective, the washer won't fill properly. It could not fill at all or it could overfill even to the point of overflowing. If the pressure switch doesn't accurately detect and control the water level in the washer, replace it.
