LG dishwashers may not start if the door isn’t fully closed. Always be sure to firmly push the door closed in order to engage the latch. If a wash cycle fails to start, this can be caused by a faulty latch. If this seems to be occurring frequently, it may indicate that your door would benefit from being examined and potentially having any damaged parts replaced to restore the dishwasher’s proper function.

 Defective Thermal Fuse

The thermal fuse will only allow power to flow through it for a specific specified period of time.

If the water in your dishwasher gets too hot, the thermal fuse will automatically cut power to the dishwasher until it cools down.

If your dishwasher is shutting off prematurely or not working at all, the hot-water heater and electrical components could be at fault so check these first.

Problem with Main Control Board

The control board is the main component of a dishwasher, sending power almost everywhere.

It may not generate enough voltage to make the dishwasher start once this is determined, it’s usually much easier to find a different problem, like a clogged hose or defective heating element.

Oftentimes these parts get misdiagnosed as faulty control boards and you may an expert appliance technician to diagnose them properly before spending too much money on a replacement part.

Faulty Touchpad

Determine if the touchpad is at fault by pressing various buttons. If some of the buttons don’t respond, this might be an indication that the touchpad or control panel is faulty and needs to be replaced.

If replacing just the touchpad isn’t possible, it’s best to replace both components together.

The timer isn’t working

The timer helps control the voltages and power products get from your breaker box to whatever is being powered.

If it’s not working properly, then the dishwasher won’t run when it should or maybe something else might not work like your refrigerator for example.

Timers are often misdiagnosed; always be sure to check more commonly defective parts before replacing the timer.

Damage door latch

When you open the door of your dishwasher, it latches shut so that it can run properly.

However, if the door is not latching properly, then there will be an issue with the door switch which prevents your dishwasher from running.

If your door latch needs to be replaced, you should contact a professional for assistance.

Defective Door Switch

The door switch prevents the dishwasher from running while the door is open. If the door switch is defective, the switch will prevent the dishwasher from running even when the door is closed.
To determine if the door switch is at fault, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.

Wash Motor Failed

Discoloration and other common issues associated with LG dishwashers can be caused by a number of problems.

The wires in the wash motor are a common area that needs to be checked when this happens, as is the pump assembly itself.

A sump pump assembly may fail if debris or sediment gets into the motor pump screen or primary strainer.
