Samsung dishwashers have become popular for many households due to their efficiency, quiet operation cycle, and sleek design. However, like any appliance, they may occasionally experience issues. One common problem that Samsung dishwasher owners face is that their dishwashers won’t turn on.
This may be unpleasant, especially if you have a mound of dirty dishes to clean. But don’t worry! In this blog article, we will analyze the probable reasons for this problem and suggest 12 simple fixes to get your dishwasher operating again in no time.
Why is your Samsung Dishwasher Not Turning On?
1. Power Supply Issues
A power supply problem is one of the most prevalent causes of a dishwasher not turning on. A blown fuse, a tripped circuit breaker, or a faulty power outlet are all possibilities.
2. Faulty Door Latch
Another possible cause for your dishwasher not turning on is a faulty door latch. If the dishwasher door is not securely closed, the appliance will not start to ensure safety during operation.
3. Damaged Power Cord
A damaged power cord could also be the culprit. Over time, power cords can become frayed or damaged, preventing the appliance from receiving electricity.
4. Malfunctioning Control Panel
The control panel is the “brain” of your dishwasher, and if it malfunctions, it can prevent your appliance from turning on. This could be due to a loose wire, a faulty control board, or a software glitch.
How to fix a Samsung Dishwasher Not Turning On
1. Check the Power Supply
Start by verifying that your dishwasher is securely plugged into the power outlet. The plug might not receive power if it is loose or not fully inserted. Next, locate your home’s circuit breaker panel or fuse box to check for blown fuses or tripped breakers.
If you find a blown fuse, replace it with one of the same amperage ratings. If a circuit breaker tripped, turn it off and back on to reset it. After addressing any power supply issues, try turning on your dishwasher again.
2. Inspect the Door Latch
Dishwashers are designed to start only when the door is securely closed. Check that the door is closed and latched. Inspect the latch mechanism for signs of damage or wear, such as cracks or broken parts.
If necessary, order a replacement door latch from Samsung or a reputable appliance parts supplier and follow the installation instructions provided.
3. Examine the Power Cord
A damaged power cord can prevent your dishwasher from receiving electricity. Carefully inspect the power cord for signs of damage, such as fraying, cuts, or exposed wires. If you find any damage, order a replacement power cord specifically designed for your Samsung dishwasher model.
To replace the power cord, unplug the dishwasher, remove the old cord, and follow the manufacturer’s instructions to install the new one securely.
4. Reset the Control Panel
Sometimes, a control panel reset can resolve issues preventing your dishwasher from turning on. To reset the control panel, unplug your dishwasher from the power source and wait at least one minute before plugging it back in.
This allows the dishwasher’s internal components to reset. If the control panel still does not function properly after performing a reset, consult a professional appliance technician for further diagnosis and repair.
5. Clean the Filter and Drain
A clogged filter or drain can prevent your dishwasher from functioning correctly, causing it not to turn on. To resolve this issue, consult your dishwasher’s user manual for instructions on removing and cleaning the filter.
Clean the filter under running water, using a soft brush to remove debris. Next, inspect the dishwasher’s drain for blockages and clear any debris found. Reassemble the filter and drain components, and try turning on your dishwasher again.
6. Check the Thermal Fuse
A thermal fuse is a safety device to prevent your dishwasher from overheating. If the thermal fuse has blown, your appliance will not turn on. To check the thermal fuse, consult your dishwasher’s user manual for its location and access instructions.
Use a multimeter to test the thermal fuse for continuity. If the thermal fuse has blown, replace it with a new one compatible with your dishwasher model.
7. Inspect the Wiring Connections
Loose or damaged wiring connections can interfere with your dishwasher’s ability to turn on. To inspect the wiring connections, first unplug the dishwasher and remove the access panel, following the instructions in your user manual.
Carefully examine the wiring connections for any signs of damage, such as frayed or broken wires, loose connections, or burnt components. Repair or replace any damaged wires or components as needed.
8. Test the Power Button
A faulty power button can prevent your dishwasher from turning on. To test the power button, locate it on the control panel and use a multimeter to check for continuity. If the power button is faulty, order a replacement part compatible with your Samsung dishwasher model and follow the manufacturer’s instructions to replace it.
9. Examine the Water Inlet Valve
The water inlet valve controls the water flow into the dishwasher. Your dishwasher may not turn on if it is broken or clogged. First, inspect the valve, turn off the water supply to your dishwasher, and disconnect it from the power source.
Next, consult your dishwasher’s user manual for instructions on locating and accessing the water inlet valve. Once you’ve found the valve, examine it for any blockages, such as debris or mineral deposits. Clean the valve using a soft brush and vinegar solution, if necessary.
If the valve is damaged or still not functioning properly after cleaning, order a replacement part compatible with your Samsung dishwasher model and follow the manufacturer’s instructions to replace it.
10. Check the Float Switch
The float switch is a critical safety feature that prevents your dishwasher from overfilling with water. If the float switch is stuck in the “up” position, it could prevent the dishwasher from turning on. To inspect the float switch, consult your dishwasher’s user manual for instructions on locating and accessing it.
Once you’ve found the float switch, ensure that it moves freely without obstruction. Remove any dirt or accumulation from the region surrounding the float switch that may be causing it to stick. Order a replacement part if the float switch is damaged or still not functioning properly after cleaning.
11. Perform a Diagnostic Test
Samsung dishwashers often feature a built-in diagnostic test mode that can help identify the root cause of issues, such as the appliance not turning on. To perform a diagnostic test, consult your dishwasher’s user manual for detailed instructions on how to enter this mode.
Once in diagnostic mode, your dishwasher will display error codes corresponding to specific issues. Note any error codes displayed and refer to your user manual or Samsung’s website to interpret their meaning. This information can help pinpoint the issue and guide you toward the appropriate solution.
If you need help resolving the problem based on the error codes, consider contacting a professional appliance technician for further assistance.
In conclusion, there are several potential reasons for a Samsung dishwasher not turning on, and just as many solutions to address the problem. You can quickly diagnose and resolve the problem by following the abovementioned procedures.
However, if you are unsure or uncomfortable performing any of the suggested repairs, consult a professional appliance technician to ensure the safety and longevity of your dishwasher.
