Samsung Dishwasher Won’t Start But Has Power – Fixed!
Tip: Follow the steps in chronological order for the best results!
1. Refresh the Dishwasher Power!
Sometimes the Samsung dishwasher panel lights kept turned on but the appliance won’t start, due to power surges or control board technical glitches.
No worries, simply power cycle the dishwasher to refresh the power supply to the appliance and solve the issue.
Here’s how to power cycle the Samsung dishwasher in easy steps:
- Stop the washing cycle and turn off the appliance.
- Unplug the Samsung dishwasher from the power socket.
- Wait for about 5 minutes for the device to discharge.
- Plug the dishwasher back into the electrical outlet.
Note: Run a test wash cycle to test whether the dishwasher will start now!
2. Reset Control Panel Settings!
When the Samsung dishwasher won’t start after restarting, reset the settings on the control panel since it’s likely for users to often misconfigure them.
This won’t change anything drastic with the dishwasher, only provide you with a fresh start.
Here is how to reset the dishwasher control panel settings:
- Find the Smart Control button from the unit panel.
- Press and hold the Smart Control for about 5 seconds.
- Keep holding the button until the “AP” appears on the panel.
- Next, press the Hi-Temp Wash button on the panel for 7 seconds.
- Keep pressing the Hi-Temp button until the dishwasher chimes.
Info: When you’re ready, it’s recommended to restart the Samsung dishwasher!
3. Clear Samsung Error Codes!
The next step is to identify whether there is an error code on the Samsung dishwasher’s control panel.
In case there is something wrong with your appliance, it may display an error code on the display, which restricts the device from starting and washing.
Here are the error codes that are proven to prevent Samsung dishwashers from starting:
| LC, LE | Leakage error |
| 3C | Drainage Pump issue |
| 1E, IE | Clogger or faulty filter |
| 3E | Water is too hot |
| 4C, 4E | Water supply issue |
| 5C, 5E | Drainage system failure |
| 7E | Water reflector problem |
| BE, 6E | Buttons are not working |
Info: If you see any error codes on the panel, as per their meaning, act accordingly.
4. Inspect Dishwasher Power Supply!
Whenever the Samsung dishwasher turns on but won’t start, make sure the circuit breaker, dishwasher power cord, outlet, and power button are in working order.
This is important since even when the appliance is receiving power, supply fluctuations will prevent the wash cycle!
- Inspect The Power Cord:
Thorly inspects the power cord of the Samsung dishwasher from both ends for any bents, breaks, and defects.
- Test The Power Outlet:
Plug another appliance into the dishwasher power outlet to test its workability and avoid plugging the appliance into a power strip or divider.
- Check The Circuit Breaker
Inspect the circuit breaker and make sure it is set to the ON position. If it is set, then reset it by turning it OFF and then turn it back to the ON position.
Test The Dishwasher!
After making sure the dishwasher is receiving the proper power supply, plug it in, press the power button, and choose the wash cycle settings.
In addition, also include the cycle time and heat temperature settings, and then wait to see if the dishwasher starts.
5. Check and Test the Water Supply!
Low water pressure or insufficient water won’t allow the Samsung dishwasher to initiate the cycle until it fills with the required water level.
Maybe the valve is turned off, not fully opened, providing low water pressure, or the inlet hose is blocked, restricting the water income.
Here is the way to inspect the dishwasher water supply:
- Locate the dishwasher valve at the bottom of the sink.
- Be sure that the Water Supply Valve is turned on.
- Also, check if the valve is clogged or damaged.
- Locate the inlet hose from the back of the dishwasher.
- Carefully remove the hose to acquire good full access.
- Clean the hose with a mix of lukewarm water and vinegar.
Important: Also check the Water Pressure by opening your kitchen tap or test it by using Water Pressure Gauge.
6. Inspect & Fully Close the Latch!
For starting the Samsung dishwasher, the door latch must be fully closed and engaged with a machine to activate the switch that alerts the board to initiate the cycle.
Hence, it’s necessary to inspect the door latch to see if is working and closing the door properly!
Here is how to check the Samsung dishwasher door latch:
- Unplug the Samsung dishwasher from the power outlet.
- Unscrew the top screws of the machine to access the match.
- Put off the bracket and press on the latch using your finger.
- Test whether the latch is moving correctly or it’s broken.
- If the door latch is broken or faulty, you’ll need a replacement.
Top Recommendation: Dishwasher Door Latch compatible with Samsung appliances!
Test the Door Switch for Continuity!
In addition to inspecting the latch, now would be the best time to check whether the door switch is functioning by using an MM600 multimeter.
By connecting the multimeter probes to the switch you can check whether there is continuity and whether the switch is operational.
Alert: Avoid contacting live wires and disconnect the appliance from the power when ready!
7. Test and/or Replace the Float Switch
The float switch in the Samsung dishwasher can occasionally become stuck and lead to misinterpretation of the water level.
This is why one of the steps that we can’t skip is to check if the float switch is operating normally or is stuck and causing the problem.
