Lg Dishwasher Not Turning On
Categories Dishwasher, Home and Kitchen, LG Dishwasher
Having an LG dishwasher that will turn on is one of the most frustrating problems. Fortunately, it can sometimes be tracked down and fixed easily.
Generally speaking, an issue with your LG dishwasher not turning on can be traced to the thermal fuse. It is designed to shut off the dishwasher when it overheats but if it is short-circuiting, it doesnt allow the power to get to the dishwasher.
You may find that there are some specific issues that are associated with your LG dishwasher that can affect its ability to operate. Some of these may be associated with getting to the dishwasher and at other times, it could be a setting that stops the dishwasher from running.
We will take a look at some of the most common reasons why an LG dishwasher will not turn on. You can then look down through the list or perhaps try some of the more specific options that are listed below.
Lg Dishwasher Not Starting
Typically, a problem with an LG dishwasher not starting can be traced to a problem with the power. Perhaps the circuit has tripped or the receptacle needs replaced. You might also have loose wires that are causing the dishwasher to not operate.
There may be other issues leading to this problem, and you can check the following:
Control Panel If you have power but no lights and the dishwasher is not operating, it may be a problem with the control board. Remove the control board and look at it carefully with a magnifying glass.
If you see any burned areas on the control board or if there are cracks in the power ribbon, the control board should be replaced.
Thermal Fuse If the thermal fuse is shorting or if it detects high temperatures in the dishwasher, it will not allow power to get to the unit. You can check the thermal fuse with a multimeter and replace it if necessary.
Touchpad Assembly If there is a problem with the touchpad assembly then pressing a button will not send a signal to tell the dishwasher to start. You can remove the touchpad assembly and clean it.
A pencil eraser is used to clean the touchpad assembly and you can also use rubbing alcohol to clean the connectors. Be very careful not to damage the assembly while cleaning it. If any issues are seen, the assembly can be replaced.
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.

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.
Control Child Lock Is Active
The control lock is the function designed to prevent interruptions while the dishwasher is still on a cycle.
If you activate the child lock feature, every key on your touchpad freezes.
You can take advantage of this program to prevent your young children from operating the machine.
But you must remember to turn off the control lock functions before you set a new cycle to run. Otherwise, the touchpad will not respond to commands.
To deactivate the control lock feature, press and hold the child lock button for about 3 seconds.

Accessing The Float Sensor And Drain Pan
Accessing the float sensor and drain pan will depend on the model of LG dishwasher that you have. If you have a kick or toe panel, removing the panel may be enough to give you access to the float sensor and drain pan. On other models, the dishwasher door or an access panel on the side of the dishwasher may need to be removed.

Test The Motor Start Relay
The motor start relay signals the dishwasher motor to start. Locate it near the pump, behind the lower access panel of the dishwasher. Remove the relay and refer to the wiring diagram. With the multimeter set on Rx1, test the coil for continuity. It should produce a reading of zero.
Then, manually activate the relay by turning it upside down, and allowing the plunger to drop. Touch the probes to the relay terminals. Expect a reading of zero. If your readings differ, replace the motor start relay.

It Could Be A Heater Element Issue
Your dishwasher is a finely tuned machine. Each cycle is activated by the cycle before it, so if the water isn’t heating to the proper temperature, it will be stuck in the heating stage and never switch to the washing stage. If this happens or you notice undissolved detergent, you may have a problem with your heater element.
- As above, disconnect the power source.
- The thick metal rod located at the bottom of your dishwasher is the heating element. Though they it look different depending on who manufactures your dishwasher, the heating element will look something like this:
- To access the wires connecting the part to the machine, remove the lower front panel of the dishwasher.
- Remove the wire connectors and label where they came from with tape.
- With your multimeter on X1, check the terminals. A properly functioning heater element will read between 0 and infinity.
- If not, remove the lock nut holding it in place Lift the element up and out. Replace with a new heater element, reconnect the wires and power.
Replace The Main Control Board
Your final option if you still havent found the cause of your LG dishwasher not working is to replace the main control board. The main control board is difficult to test and repair, so the best option is to just replace it completely. However, given the cost of buying a new control board and the uncertainty that replacing it will make your dishwasher work again, you might decide the better option is to purchase a new dishwasher.

Dishwasher Not Getting Power
If the LG Dishwasher wont start, you can check to see if there is an electrical connection by unplugging and then plugging in the dishwasher. If it does not start up after doing this, try flipping over a nearby circuit breaker or resetting your homes main fuse.
Make sure your dishwasher is plugged in: Check the power cord that goes from your dishwasher to the outlet.
If there is a break in it, you will need to replace it or repair it. If you have an extension cord plugged into another plug and then on top of that has another wire going from this extension cord to your dishwasher, make sure nothing else was using electricity at the time when it stopped working.
This could mean unplugging everything before checking for other problems with your LG Dishwashers! Do not forget about outside sources such as lightning or even electrical surges protecting against storms! You do want to consider all possibilities if they are possible causes of LG dishwasher issues.

There are two ways of fixing it when this happens- by turning off and then back on or simply flipping the switch for the appropriate breaker in your electrical panel.
Circulation Pump And Drain Pump Motor
This pump uses an impeller and motor to propel the water through the wash arms. If you notice a humming noise after the dishwasher has filled or if you don’t hear any sound at all, it could mean that the motor is burned out. Debris in the pump housing can also prevent the impeller from turning. If there is no power to the motor, this could also be the cause of the problem. Such faults are best diagnosed by .
