Washer: Won't fill
If your washer doesn't fill with water, first check that the house water supply to the washer is on. If it is, and the washer won't fill at all, the inlet valves might have failed. If it fills partially, a problem with the temperature selector switch or water-level pressure switch is likely. If the washer agitates without filling, then the pressure switch is likely broken because it’s detecting the tub full of water when the tub is empty. Other components that control your washer filling with water include the main electronic control board, the door lock assembly, the washer lid switch and the electronic temperature control board. Find the repair listed below that matches your problem, order the part and then follow the step-by-step instructions in our repair guides to get your washer filling with water again.
These repairs may help solve your Washer problem:
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 temperature selector switch
The temperature selector switch lets you set the temperature of the water going into the washer. The temperature selector switch switch is usually a rotary switch mounted in the control panel. If the switch fails, the washer won't fill properly or might not fill at all. If one of the water inlet fill valves isn't actuated because of defective contacts in the switch, the actual water temperature differs from the set temperature.
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.
Replace the washer main electronic 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 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 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 electronic temperature control board
The electronic temperature control board has a thermistor (a temperature sensor) that detects the temperature of the water entering the tub. The electronic temperature control board opens and shuts the electrically operated water inlet valves to accurately fill the washer tub with the correct temperature of fill water. If the electronic temperature control isn't controlling the fill water temperature properly, replace it.
