Samsung Dishwasher Not Powering On? – Learn How to Fix

Are you facing the Samsung dishwasher not powering on? That’s quite a lot of trouble.

After all, you will be forced to allot time to wash the dishes by hand.

If Samsung dishwasher is not powering on, check its power switch and inspect the circuit breaker as a first measure. Moreover, you might need to change the power cord, replace the thermal fuse or install an entirely new control board.

Most of the solutions will require you to get down to work. However, you don’t need to worry too much.

We will cover every step you must perform so that you can fix everything swiftly.

Samsung Dishwasher Not Powering On – Reasons

The Samsung dishwasher will not turn on. So then you are forced to wash the dishes by hand, wondering what’s wrong with your appliance.

When that happens, there are a lot of causes that could be preventing the proper functioning of the machine.

Some are silly, while others are serious and require careful handling when troubleshooting. 

✅ The Power Switch Is Off

Some newly built houses have a power switch close to the sink, just where the dishwasher must be placed. It won’t allow the dishwasher to turn on when it is off.

✅ Tripped Circuit Breaker

If your house has different circuit breakers for different rooms or parts of it, perhaps the circuit breaker providing energy to the dishwasher has been tripped.

✅ Blown Thermal Fuse

The thermal fuse is responsible for controlling the appliance’s heat. When it blows from too much use, the dishwasher might fail to turn on.

✅ Damaged Control Board

If nothing happens when you try to power your dishwasher, the control board can be at fault.

✅ Defective Power Cord

It is safe to assume that a dishwasher without power has a power cord that is no longer good. That is cheaper to replace than a control board.

Fixing A Samsung Dishwasher Without Power

After reading the most probable causes, you are surely hoping that the issue behind the Samsung dishwasher won’t power on, just some silly cause.

The sections below will help you assess the situation and do whatever’s necessary.

1. Check The Individual Power Switch

Is your house newly built? In that case, the odds are it has a power switch for some appliances in your kitchen or simply for the dishwasher. 

• Wherever the dishwasher is positioned, follow its power cord until you find the power source.

There should be a power switch close to it. Then, turn it on and see if the dishwasher works now.

2. Inspect The Circuit Breaker

Similarly to the individual power switch, the circuit breaker on your house might be designed so that you can cut power to one environment only.

Also, older houses might have their circuit breakers tripped without any apparent reason.

In any case, you must check your house’s circuit breaker box. If there is more than one, you need to test them until you find the one responsible for the kitchen. 

3. Test The Power Cord

When the Samsung dishwasher constantly fails to power on, one possible cause is the power cord being damaged or utterly defective.

You can test it with a multimeter:

1. Unplug the power cord;
2. Place the multimeter’s probes on the power cord’s metal prongs. 
3. Adjust to continuity
4. If it doesn’t beep, the cable is the issue.

Note: If the dishwasher is still under warranty, you must contact Samsung. If it is not, then the situation is unfortunate. 

However, you can still replace the power cord easily.

Replace The Power Cable

Replacing the power cable of your dishwasher is easier than you might think. All you have to do is find a cable with the same electrical specs.

You don’t want a weak cable, and you also don’t want one too strong that will end up frying the appliance. 

1. Put the dishwasher on a flat surface;
2. Find where the power cord is located;
3. Remove anything that protects access to it;
4. Unscrew the screws that secure it;
5. Disconnect the internal wiring to release the cable;
6. Connect the new electrical cable to the inside wiring;
7. Reattach each of the fastening screws.

After that, the dishwasher will surely work.

4. Replace The Thermal Fuse

All dishwashers have fuses that might blow after long use. The thermal fuse, for example, when blown, will prevent many of the dishwasher’s normal functions.

A few times, it will even prevent the appliance from turning.

Here is how you can check whether it is blown:

1. Disconnect the power supply to the dishwasher;
2. Remove the screws that hold the control panel in place;
3. Carefully detach the panel from the dishwasher;
4. Look for the thermal fuse, a small cylindrical device with two wires.

Once you know that you’ve located the thermal fuse, you grab a multimeter. Then:

1. Set the multimeter to the continuity or ohms setting;
2. Touch the probes to the two ends of the thermal fuse;

• If the multimeter shows a reading of “0” or is close to “0”, then the thermal fuse works fine.

However, if there is no reading, the thermal fuse has blown and must be replaced.

How To Replace The Fuse

After finding out that the defect is on the thermal fuse, you must work to replace it.

You can find a new thermal fuse at online retailers or local stores. You must pay attention to the electrical specs of the new thermal fuse.

1. Disconnect the two wires connected to the fuse;
2. Remove the fuse from the dishwasher;
3. Put the new thermal fuse in place;
4. Attach the wires;
5. Reinstall the control panel;
6. Secure it with screws;
7. Reconnect the power supply.

After reconnecting the power supply, you must perform a test. For example, the dishwasher must be able to receive power now.

5. Install A New Control Board

In the worst-case scenario, the issue on your dishwasher is directly on the control board. Unfortunately, that means you will have to change it entirely. 

First, ensure you have unplugged the dishwasher. Even though it is not powered on, you never know whether electricity flows through its wires.

Then start doing this:

1. Open the dishwasher’s door;
2. Remove the inner door’s Torx screws;
3. Remove the outer door panel from the inner panel;
4. Detach the wire harness of the user interface control;
5. Pull off the control panel;
6. Raise the locking tab;
7. Move the control board to the left;
8. Release it from the inner door panel;
9. Detach the cover locking tabs;
10. Disconnect all harnesses, braces, and wires.

Now you have successfully removed the defective control board.

Remember to discard it correctly so its parts can be recycled. 

Install The New Control Board

You can buy a new control board for the Samsung dishwasher from the internet or at a local store.

After you’ve removed the damaged one, it is easy to see what the correct replacement must look like. Then:

1. Take out the new part’s cover;
2. Attach the new board’s wires to the dishwasher’s loose wires;
3. Put the wire harness connector brace in place;
4. Also, install the connector box cover;
5. Put the electronic control board cover;
6. Slide the new control board into its place;
7. Ensure it goes into the locking tab

After that, you will also have to reinstall the door. All you have to do is follow the procedure of removing, but backward.

You must ensure that the screws are tight in place.
