Dishwasher Won't Start? All the Easy Fixes You Need to Know
Your dishwasher can save valuable time and energy in the kitchen. While regular maintenance can help prevent common operating issues and keep your appliance running like new for years to come, occasionally a faulty component needs to be repaired or replaced. Instead of calling a repair person, troubleshooting and even repairing a dishwasher yourself can be simple with a little know-how. Our friends at Sears Parts Direct offer some easy tips to fix a dishwasher that won't start.
Replace the Door Latch Assembly
If the dishwasher door won't shut completely, this can prevent the appliance from starting. The door latch assembly casing can become physically broken, but the electronic mechanism within the component can also fail over time. If the latch doesn't lock or or the micro-switch inside doesn't engage, replace the part.

Replace the Thermal Fuse
If the dishwasher isn't receiving power, even though there is power being supplied to the appliance, the problem could be the thermal fuse. On some models, certain components will still operate even though the fuse is blown, but the wash cycles will not initiate.

Replace the Control Panel
Over time the dishwasher control panel can become loose or damaged due to everyday use. Be sure to inspect both the front and back of the control panel for issues. Stuck buttons and loose or frayed wires can all prevent your dishwasher from starting.

Replace the Dishwasher Bi-Metal Thermal Fuse
The bi-metal thermal fuse can be blown in the event of a power surge or as a result of another faulty component in the appliance. Like with the other dishwasher thermal fuses, a problem with the bi-metal thermal fuse can be identified if your appliance isn't receiving or is only receiving limited power even though there is power being supplied to the unit.

Replace the Timer
From the wash and drain pumps to the inlet water valve and heating element, the dishwasher timer controls all the electro-mechanical components in your appliance. It's also responsible for advancing the control knob as a wash cycle progresses. A faulty timer can prevent one or all of the components it controls from starting and needs to be replaced.

Replace the Water Inlet Valve
Problems with the water inlet valve will result in the appliance over or under filling with water before, during and after a cycle, depending on the specific issue. If the water inlet valve, otherwise knokwin as the solenoid fill valve, doesn't open or close completely or partially, then it needs to be replaced.

Replace the Power Supply Control Board
This secondary supply control board is included on some dishwasher models and can cause problems with the primary control board if it is malfunctioning. Check to make sure that this part is receiving and delivering power as intended.
Replace the Cycle Selector Switch Assembly
The cycle selector switch is a part of the dishwasher control panel on some models. If the selector switch does not initiate, then it needs to be replaced.
