Dishwasher Wont Turn On 10 Steps To Fix It
Often there is a simple solution for a dishwasher not turning on, such as a loose wire. Other causes can be diagnosed with a multimeter and easily fixed by replacing the part.
To order a replacement part, you will need to know your dishwasher model. Consult your manual, or sometimes you will find model information on the exterior sides of the dishwasher or inside the dishwasher door.
Pro Tip: If taking the dishwasher apart, wear gloves to protect yourself from cuts, as the metal can be sharp.
Remember to unplug your dishwasher or switch off its power from inside your electrical panel before checking electrical components.
Lg Dishwasher Starts And Stops
Do you have a problem with your LG dishwasher starting and stopping? This may be part of the normal operation. LG dishwashers will pause between cycles.
If it is not a part of normal operation, check for any error codes that may exist. You can search the manual for information about error codes and how they can be repaired.
If you are dealing with a faulty door latch or switch, it may be telling the dishwasher that the door is coming open periodically. This often happens when there is pressure in the dishwasher that pushes against the door.

You can check the door switch and latch manually and the door switch can be checked with a multimeter. They should be replaced if necessary.
When the thermal fuse is shorting out but has not yet broken, it may cause the dishwasher to start and stop. The thermal fuse is designed to break the path of electricity if high temperatures are detected. If it is shorting out, the flow of electricity may start and stop.
Door Latch Is Not Engaged
To start a wash cycle, the door must be completely closed and its latch engaged. Why wont my LG dishwasher turn on until the latch engages? The latch prompts the door switch to initiate a wash cycle and prevents messy dishwasher leaks. When closing the door, make sure you give it a firm push to engage the latch. If your LG dishwasher wont start even if the door is closed properly, the latch may be damaged and requires professional replacement.

What Triggers The Ae Error Code
The AE error code is triggered by the float sensor in the dishwasher detecting too much water in the bottom of the dishwasher. Depending on the model, the float sensor usually sits in a pan at the bottom of the dishwasher that collects water if the dishwasher has a leak. If there is too much water in the pan, the float sensor tells the control board to stop working until the pan is emptied.
Emptying or wiping up the water in the pan can resolve the AE error code however, there may still be a leak that will need to be fixed to stop the AE error code from occurring again.

Check The Dishwasher Power Cord
Some dishwashers have a power cord that plugs into an electrical outlet under the sink, while other dishwasher power cords are wired directly from the wall to the wires in the dishwashers junction box. If your dishwasher power cord plugs into an electrical outlet, make sure the power cord is plugged in.
If the power cord is plugged in, its possible the electrical outlet doesnt work. Check the electrical outlet for power by plugging in a small lamp. If it doesnt light up, have an electrician repair the bad outlet.
Heres a helpful troubleshooting video that shows this step and additional troubleshooting steps to take when your dishwasher has now power.
The Drive Motor Could Be The Problem
The work of the drive motor is to power the circulation pump so that it can force water through the holes on the spray arms to wash your dishes at high pressure.
If the drive motor is faulty, water will not come out from the holes of the spray arms at high pressure. As a result, your dishes will still come out of the unit dirty.
Worst of all, when the motor dies, no power goes to the circulation, which means no cleaning can take place.
Youll have to replace the drive motor to get the LG dishwasher to star working again. To do that:
- Start by cutting off the power supply and then turning off the water supply.
- Dismantle the dishwasher .
- As you disassemble the unit, make sure you note the way every component connects so that you wont have a difficult time reassembling the unit.
- Remove the interior water guide.
- Take out the malfunctioning water assembly and install the new one.
- Reassemble the appliance and ensure that everything is fixed back correctly so that the system works.

Need To Change Dishwasher Settings
Is your LG dishwasher not starting on command? Certain control panel settings or codes may tell you why.
Check the control panel for the following:
- A cycle is selected: The dishwasher wont begin washing unless a cycle is selected.
- The cycle includes an immediate start: Some cycles, like Delay Start, push back that start of a wash cycle to a later time. Other settings, like Child Lock, lock the control panel to prevent an accidental start. Refer to your user manual to disable these functions, as the method varies from model to model.
- Error codes: Error codes are a combination of numbers and/or letters that alert you to a potential problem. Refer to your user manual to determine the meaning of the code and how to resolve it.
- Control panel failure: Excessive moisture or electronic failure can damage the control panel so it wont relay commands. If one or more buttons are unresponsive, the control panel may require replacement.
Check The Touchpad Or Buttons

Need To Adjust Lg Dishwasher Settings
Is your LG dishwasher not working even if it has power and the door is closed properly? Check your control panel to make sure you selected a wash setting. A wash cycle wont start unless you select a setting before pressing the Start button. If you find your dishwasher not drying dishes sufficiently also select an extra or heated dry option, if available.
Your control panel will also let you know if the wrong setting or an error code is preventing an immediate start.
The following LG dishwasher settings and alerts prohibit it from starting immediately:
- Control Lock: Prevents changes from being made during a wash cycle by locking all control panel functions, including the Start button.
- Delayed Start: Delays the start of a wash cycle to a preset later time
- Error codes: Uses a series of numbers and/or letters to signify a problem, potentially preventing an immediate start.
Consult your LG user manual to determine how to disable specific functions on your model dishwasher and decipher an error codes meaning. Lastly, your control panel may not respond properly if its exposed to excessive moisture. If one or more buttons on your control panel is unresponsive, it must be professionally replaced.
The Drain Pump Is Broken Or Clogged
The drain pump works by forcing water through an impeller and down the drain hose. If the hose becomes bent or clogged, it will not function properly, and you may see the lights on the control panel flashing. This will definitely prevent the dishwasher from initiating a new cycle, and you’ll need to check the pump using a multimeter.
If the pump does not have continuity, you will need to replace it before using the dishwasher again. Note that this part isn’t repairable. You’ll simply have to purchase a new one, unfortunately.

Problem With Dishwasher Water Supply
Water supply issues can also be responsible for an LG dishwasher not working properly. If you notice that the dishwasher has power but doesnt fill and begin a wash cycle, there may be a water supply problem.
Use these tips to assess the dishwashers water supply:
- Check water supply connection: Make sure the dishwasher is properly connected to your home water supply and that the supply valve is on.
- Examine dishwasher hose: Check the dishwashers water supply hose for kinks that could obstruct water flow. Gently straighten the kink, if possible.
- Assess water inlet valve: If the water inlet valve on the hose has malfunctioned, it wont open and allow water to supply the dishwasher. If the valve has visible damage or multimeter testing shows no continuity, it must be professionally replaced.
Check Door Latches And Switches
If your dishwasher doesnt start, you may need to replace the door latch or the switch for the door latch. The door latch assembly is designed to hold the door closed during a cycle. It also houses switches that provide electricity to controls inside the dishwasher. If the door cannot close, or if the switches are defective, then your dishwasher will not start. Inspect the latch assembly for function and damage.
A broken latch assembly can also prevent your machine from starting. Inspect for damage or loose connections in the switch mechanism at the top of your dishwasher.
Locate the door switch at the top of the dishwasher and make sure that it is activated when you close the machine. A continuity test with a multimeter will also work, but be sure your power to the dishwasher is turned off first.
