You just loaded your Frigidaire dishwasher, pressed the start button, and waited for it to begin. But nothing happens, even though the dishwasher has power. That feeling is frustrating! You want your dishes cleaned, not more hassle. The good news is that many times, this problem has simple fixes you can try right at home. In this article, you will learn how to get your dishwasher working again with easy steps, so you don’t have to call a repair person right away.
Check the Door Latch and Door Switch
One of the most common reasons your Frigidaire dishwasher won’t start even though it has power is the door latch or door switch problem. The dishwasher will not start if the door isn’t fully closed or if the latch does not engage properly. This is a safety feature to keep water from leaking out.
First, open the door and check if there is any dirt, food, or debris blocking the latch from closing fully. Sometimes, small bits of food can stop the door from locking. Clean the latch area gently with a damp cloth. Next, close the door firmly but don’t slam it. You should feel or hear a click, which means the latch has locked the door.
If the latch looks fine but the dishwasher still won’t start, the door switch might be faulty. The door switch tells the dishwasher that the door is closed and it is safe to start. You can test the door switch with a multimeter if you have one, or press the switch manually to hear a click sound. If the switch is broken, it needs to be replaced.
- Check for dirt or debris in the door latch area
- Clean the latch with a damp cloth
- Close the door firmly until you hear a click
- Test or replace the door switch if needed
Inspect the Control Panel and Buttons
If your dishwasher has power but doesn’t start, the problem might be in the control panel or buttons. The control panel is where you choose the washing cycle and start the machine. Sometimes, buttons can get stuck, or the panel can have electrical issues.
Start by making sure no buttons are stuck or pressed down all the time. Try pressing each button one by one to see if the dishwasher reacts. If a button feels sticky or does not move freely, clean around it with a soft cloth slightly dampened with water. Don’t use too much water because it can damage the electronics.
If cleaning doesn’t work, the control board (the circuit board inside the panel) could be damaged. This usually requires a professional to check or replace, but sometimes resetting the dishwasher can help. To reset, unplug the dishwasher from the power for about five minutes, then plug it back in and try again. This can fix small glitches.
- Check if any buttons are stuck or sticky
- Clean buttons gently with a damp cloth
- Try resetting the dishwasher by unplugging it for 5 minutes
- Consider a professional if the control board is faulty
Check the Power Supply and Circuit Breaker
Sometimes your dishwasher shows power (like the lights are on), but it won’t start because of power issues inside the home wiring or the dishwasher plug. Even if your dishwasher looks like it has power, there could be a weak or inconsistent supply causing it not to start properly.
First, check if the dishwasher is properly plugged in. Sometimes the plug can be loose or partially out. Make sure it is fully plugged into the wall socket. Next, check your home’s circuit breaker panel. Find the breaker switch for the dishwasher and make sure it hasn’t tripped. If it has, flip it off and on again to reset it.
Also, if your dishwasher is connected to a power outlet with a ground fault circuit interrupter (GFCI), it might have tripped. Press the reset button on the outlet and try starting the dishwasher again.
If you still have problems, there might be an issue with the wiring inside the dishwasher or your home’s electrical system. This will need an electrician or repair technician.
- Ensure dishwasher plug is fully inserted in the socket
- Check your circuit breaker for tripped switches and reset if needed
- Reset GFCI outlets if your dishwasher is connected to one
- Call a professional electrician if wiring issues are suspected
Look at the Start Relay and Motor
Your dishwasher’s motor and start relay work together to begin the wash cycle. If the motor doesn’t get the signal to start, your dishwasher will not work even if it has power. The start relay is a small switch that sends electricity to the motor to turn it on.
If your dishwasher won’t start, the start relay might be broken or the motor could be stuck. You can hear if the motor tries to start by listening for humming or clicking noises. No noise at all could mean the motor or relay is dead.
To check the relay, you may need to open the dishwasher’s lower access panel. The relay looks like a small box attached to the motor or near it. If you have a multimeter, you can test the relay for electrical continuity. A faulty relay needs to be replaced.
If the motor is jammed or burnt out, it also must be replaced. Sometimes small items like broken glass or utensils block the motor from turning. Carefully check inside the dishwasher base for any blockages.
- Listen for motor humming or clicking when starting
- Open lower panel to find and inspect start relay
- Test relay with a multimeter if possible
- Remove any objects blocking the motor
- Replace relay or motor if faulty
Examine the Timer or Electronic Control Board
Older Frigidaire dishwashers often have a timer that controls the wash cycle. Newer models use an electronic control board instead. If these parts fail, your dishwasher may not start even with power.
If your dishwasher uses a timer, it can stop working due to wear or electrical faults. A bad timer means the machine won’t move to the start position. You can test the timer with a multimeter or watch if the timer dial turns when the dishwasher is on.
For dishwashers with an electronic control board, problems can come from damaged circuits or bad solder joints. Sometimes boards get wet or worn out. Resetting the dishwasher by unplugging can help for minor glitches, but often the control board must be replaced if it is faulty.
Check for signs of burnt components, loose wires, or water damage inside the control panel. These are clues that the timer or board needs repair.
- Test timer operation and continuity with a multimeter
- Look for damaged parts on control boards
- Reset dishwasher by unplugging to fix small issues
- Replace timer or control board if broken
- Inspect for water damage or burnt areas in the panel
Check the Thermal Fuse and Safety Devices
Dishwashers have safety parts like a thermal fuse to protect from overheating or electrical problems. If the thermal fuse blows, your dishwasher may have power but refuse to start.
The thermal fuse is usually located near the control board or heating element. It cuts power to the dishwasher if it senses a problem. A blown fuse must be replaced to restore function.
To check the thermal fuse, unplug the dishwasher and find the fuse location using your model’s manual. Test the fuse with a multimeter for continuity. No continuity means the fuse is blown.
Besides the thermal fuse, some dishwashers have other safety sensors or fuses that can stop the machine from starting. Check these as well if your dishwasher won’t run.
- Locate and test the thermal fuse for continuity
- Replace the thermal fuse if it is blown
- Check other safety sensors or fuses in the dishwasher
- Always unplug before inspecting electrical parts
Final Thoughts
