How to Fix a Dishwasher that Will not Turn On: A Conclusive Guide


My dishwasher is not turning on. The dishwasher functioned just a few days ago, but the dishwasher is not turning on. The dishwasher has no power, lights, or sound emanating from it. What part of the dishwasher may be the cause of this issue? Could it be a power issue, or is something wrong with the dishwasher? Let’s review how to fix a dishwasher that will not turn on.

How to fix a dishwasher that will not turn on

Timers or electronic control

Have you checked the latches and discovered they’re working properly; however, the dishwasher hasn’t started to run once more? Checking your electronic controls or timing device is your next step. If your dishwasher comes with an automatic timer and you hear an emitted sound when the timer provides electricity to all the elements of the process in order beginning with the drain pump, which is used to eliminate excess water in the drain, and then to the valve for water inlet followed by the heater, and finally, the drain pump. The first step is to unplug the dishwasher and remove the door’s interior panel. The timer can be located behind the control panel on the dishwasher’s top. Inside the timer’s housing are various contacts controlled by a small motor.

Lookup a diagram for the dishwasher model in your owner’s manual or on the manufacturer’s site. This diagram should indicate the timer contact points for the circuits for the motor and the intake valve. Utilize your multimeter for checking the timing contacts. If you own an electronic control system, it is the primary circuit board that controls the valve and motor circuits by using a microprocessor and electrical relays. An error code could appear when the panel is removed, and you should request a service technician to conduct live voltage checks for the relay’s outputs. It is also possible to look over the section of this guide marked as the thermal fuse.

Pressing the right button

Numerous buttons are on your dishwasher. Press the START button, power and ON button to turn on your dishwasher. If you’re pressing the right power button on your dishwasher’s panel, check if it’s receiving electricity or if the dishwasher connects to the.

Motor start relay

The model you have will depend on your dishwasher; it could have the main pump motor operating by the start relay. The relay will provide electricity to the motor start windings using a rotating plunger, which runs a series of contacts. If the power is flowing through the control circuits to the motor, but the dishwasher isn’t operating, then perhaps it is the relay that starts motors that require change. Start by disconnecting the dishwasher before finding the motor. The relay will position next to it. Follow the wiring diagram in the owner’s manual or manufacturer’s website. Examine the coil section using a multimeter to ensure there is continuity. Turn over the switch. If the plunger falls into the switch’s contact, it should be in continuity.

Drive motor

The water circulates to wash the dishes in your dishwasher thanks to your drive motor. Suppose you’ve examined the electronic control/timer and starting relays. In that case, the next thing to examine within the chain of operations is the motor that drives it. If the motor does not spin, it can because of the windings damage. A loud hum coming from the motor can also signal this component is malfunctioning, as that hum might be a sign that the motor broke and needs to replace. Unplug the dishwasher, take off the kickplate on its lower side and test the motor’s windings using a multimeter to ensure they’re in good working order.

Make sure the dishwasher is receiving electricity

If your dishwasher connects to the GFCI-type outlet. Set the GFCI outlet in case it trips. Press the reset button located on the outlet to restart the power. The dishwasher will turn on when you have reset your GCFI outlet.

Check the latch on the door

Make sure that the door is closed to the fullest extent. If the dishwasher’s door latch isn’t in use, a small switch will stop it from operating. Take a look at every side to see if there is anything that may be preventing it from shutting properly. Examine for broken parts or issues in the door. The latch on the door is defective and should replace.

Set dishwasher time properly

Ensure that the water valve is switched on for the dishwasher and that sufficient water pressure flows into the dish. Some dishwashers will not come on if there isn’t enough or insufficient pressure. When the dishwasher is running at the right water pressure, it will start to turn on.

Thermal fuse

Suppose the dishwasher you control electronically has a thermal fuse. In that case, the control board relies on that fuse for power, and the appliance won’t start when the fuse fails. Unplug the dishwasher, remove the door’s inner panel, and locate the thermal fuse and its two wires above the panel. Unplug the two wires, and then use a multimeter to verify continuity.

Turn on the water valve

Have you opened the dishwasher during its operation? The dishwasher may have stopped working between cycles because you disrupted the wash cycle, and it cannot restart. Switch off the power and then switch it back on. Try pressing the button to start for 10 secs. Disconnect the dishwasher from the power for 60 minutes if that doesn’t work. After resetting the dishwasher, you will be able to operate it normally.

Reasons why dishwasher won’t turn on

Incorrect dishwasher setup

A wrong setting for the cycle can cause the dishwasher not to start. Most dishwashers have an option for children to lock that blocks all functions to stop the possibility of an unintentional start. The delay start feature can be used to prevent the immediate start of washing at a pre-determined time. If one of these functions is turned on, it will stop the dishwasher from starting immediately upon command.

Consult your user’s manual to find the best way to disable your child lock or defer setting for your particular model dishwasher. Most of the time, pressing a set of buttons or switching off the dishwasher will disable the specific setting.

Control panel malfunction

Are your dishwasher’s lights not working even if it has a latch in place? A variety of possible problems with the control panel could stop it from running. Sometimes, pressing the Start button repeatedly causes the dishwasher to run through a brief drain cycle. Are you wondering how to reset a dishwasher after this drain cycle? Give it 60-90 seconds to finish before you give the Start button one press. If you notice that the dishwasher’s Start button is not working, other buttons are lit, and the switch that controls it might have failed. If the switch doesn’t show continuity using a multimeter test, it needs replacement. If you notice that no dishwasher’s lights come on, the control panel may malfunction regardless of trying different functions. If this computerized component ceases to work, generating electric signals, it needs to be replaced professionally.

Power supply problem

If your dishwasher doesn’t come on, you must first verify its power sources. If there isn’t enough electricity, a dishwasher won’t be able to start or perform any task. Check that the dishwasher’s power cord connects to an electrical outlet that works. The outlets for dishwashers are often in cabinets, where items could knock the cord off the wall. Check the circuit breaker in your home’s box and move any tripped breakers. Extension cords cannot safely conduct the voltage needed to allow a dishwasher to function and can cause surges to cut the electricity.

The electronic timer is broken

If your dishwasher doesn’t begin on its own, it could be that the electronic timer is defective. The timer in a dishwasher controls the time when power is transmitted to a specific function that is part of its wash process. Notice your dishwasher is not draining the water correctly or isn’t starting in the way it should. It is because your timer or the connection with the panel was damaged. A defective timer must inspect and replace by a skilled repair service.

Door locks that fail

When activated, the latch on the dishwasher door secures the door. It alerts the control panel inside that the wash cycle is ready to begin. Suppose the latch is damaged, either malfunctioning in electronic or mechanical ways. In that case, the latch will not send a signal to the control panel, and the dishwasher will not turn on. Examine the latch for evidence of damage, or test it using an instrument to see if it is in good working order. If the latch exhibits obvious damage or fails to test with a multimeter without continuity, it needs to be replaced.
