Top Causes and How to Fix Dishwasher That Won’t Start

It shouldn’t be surprising that dishwasher have become a crucial component of Melbourne households throughout the years. After all, they make your life a hundred times more accessible and are amazingly simple and convenient. This helps you to focus on more essential elements of your home and your daily obligations.

It makes sense to use a dishwasher. All you need to do is fill your container with the soiled silverware and dishes. You won’t have to waste time washing them by hand with this handy device.

Like any other home appliance, your dishwasher could, however, begin to malfunction with time. That is one of the most frequent issues when they don’t start even after you’ve clicked the power button. Try doing your self-diagnosis of the issue before hiring a repair specialist. This is the procedure.

Your dishwasher won’t start? Here are 4 Causes and Solutions

There are several causes for your dishwasher not to start, but the door latch assembly, electric control timer, selection switch, and thermal fuse are the most likely culprits. Your dishwasher might not start if one of these parts malfunctions.

Before starting the troubleshooting process, try these steps:

Verify that the dishwasher is plugged in. Although it may seem obvious, sometimes forgetting the most essential things is more accessible. It follows that occasionally, the dishwasher won’t run simply because it has yet to be plugged in.

Examine your circuit breakers. If your dishwasher is already plugged in but won’t operate, the circuit breaker may malfunction. Go to the breaker box in your home and see if the switch is in the incorrect position. As an alternative, you can detect specific overheating symptoms. If the latter, it is advisable to let a professional handle the issue.

Check to make sure the child lock setting is not engaged. On the control panel of some dishwasher models is a kid lock button. It is a safety function that stops kids from unintentionally changing the settings on your appliance, particularly during the wash cycle. Additionally, it can stop your dishwasher from starting.

Your dishwasher reset. Even with the lights on, does your dishwasher not operate? Your appliance may need to be reset. You only need to unplug the equipment. Wait for about a minute before connecting it back in and turning on the power. Depending on the model of your dishwasher, the precise processes may change, so be sure to read the manufacturer’s instructions.

If none of these suggestions work, continue reading to identify the cause of your dishwasher’s issues and the recommended fix. Before beginning, remember to unplug the appliance from the power source.

Let a qualified appliance repair specialist handle the job if you are unclear on how to continue. The last thing you want to do is to harm your dishwasher further.

A multimeter will be used for several tests listed below, another crucial point to remember. Make sure it is correctly calibrated before using it.

faulty door latch

First, a subpar door latch assembly
Your dishwasher’s inability to turn on is frequently caused by a problem with the door latch assembly, including the door latch switches. In essence, the door latch assembly’s job is to keep the dishwasher door shut while the cycle is running to stop the water from dripping. It also houses the door latch switches, which are in charge of sending electricity to the controls on your dishwasher.

If the door closes tightly or the latch switches are damaged, your dishwasher’s controls might only get the electricity required to turn on and perform as intended. The door latch assembly will need to be changed in this situation.

How to examine the door latch system

Before beginning, be careful to unplug your equipment.

The door latch assembly’s location. Usually, you can find it above the door of your dishwasher. You may need to remove the inner door panel to access the assembly. Consult the owner’s handbook if you need help finding the latch assembly.
Please verify that the door latch assembly is appropriately activating the switches after locating it. To accomplish this, place the door catch inside the assembly. If not, it must most likely be replaced because it is broken.

If the door latch switches on your dishwasher are mechanically operated, carefully remove them from the assembly.
Make use of a multimeter to check the switches for continuity. A reading of zero or almost zero is what you should receive. If the screen reads something different, the door latch assembly is probably faulty and needs to be replaced.

Faulty Selector Switch

Check the electric timer control to see if the door latch assembly is not the offending component. This part, connected to the control panel, determines how long the wash cycle will last. Your appliance may not switch on if the electric control has failed since the timer won’t have the power it needs to start the cycle. The same holds if the timer and the control panel are misconnected.

Test the electric control here:

Remove the dishwasher’s plug.

Find the timer on your appliance, then remove it. As was indicated earlier, it is typically located in the control panel.
Make careful to refer to the wiring schematic for your model if your timer has several contacts. This will help you determine which contacts or wires need testing.

Set your multimeter to the Rx1000 setting to get it ready. Using the appropriate contacts, connect to probes. Dishwasher timer resistance is commonly measured between 2000 and 3500 ohms, yet it can still differ from one make to another. Once more, make sure by consulting your owner’s manual.

You’ll need to buy a new electric control timer if the reading you receive is outside the advised range.

Inadequate Selector Switch Operation

The selector switch lets you choose various choices for every wash cycle, including heating, drying, and washing. If the switch is broken, depending on the model and make, your dishwasher may not start. The fact that it is not fully depressed or that multiple buttons have been pressed simultaneously are other potential causes.

Performing a selection switch test

Always unplug your appliance from the source of power.

To access your start switch, you must disassemble the dishwasher door, particularly the inner door panel. It frequently appears in the control panel.

Once the switch has been located, make sure it is properly pressed. If not, gently pry it away from your appliance.
Touch the probes to the proper wire terminals after setting the multimeter to the RX1 setting. Be extremely patient during this phase because you must test each button individually. You should receive an infinity reading during the initial test.
Keep the probes on the terminals for the second test, then hit the button attached to the terminal you are testing. This time, the reading on the display ought to be zero.

For the remaining buttons, conduct both tests once again.

Any of the tests above that are unsuccessful show that the selector switch is broken and has to be replaced.

Thermal fuse failure

The safety feature of your dishwasher is the thermal fuse. It shuts off power to the control panel if a short circuit in the wire occurs or your appliance overheats. A thermal fuse that has tripped or burst can aid in putting out fires, but it may also make your dishwasher inoperable. You have no alternative except to change your thermal fuse in this situation.

Performing a thermal fuse test

Start by cutting off the dishwasher’s power source. Keep in mind that you will be handling electrical components.
Remove the inner door panel from your dishwasher to access the thermal fuse. Usually, two cables are used to connect it to the control panel. Disconnect and remove the wires to test the thermal fuse for continuity.
Place the probes next to the fuse’s terminals after setting your multimeter to the RX1 setting. You ought to obtain a reading of zero or almost zero. If not, you must replace the thermal fuse.
