Hi.
Usually it is the heating element...but to make sure you can access the wires easily from the front underneath when the front kick plate is off...run the dishwasher and then use a volt tick to check if power is going to the element when it should be heating....it is hard to get to the actual connections, so a voltage detector will work better and be safer...
If you are getiing no voltage then the realy on the main board at the top of the door is gone....

A bad heating element causes many problems in dishwashers…

Dishwasher not drying dished with any heat source. Dishes washed in cold water.


Most dishwashers are plumbed to the hot side of the hot water side of the faucet. This should provide hot water for washing the dishes. Perhaps this dishwasher was plumbed to the cold water side by mistake.

Most dishwashers have a heating coil most of the way around under the bottom sliding/rolling dish rack. The heating coil may not be working, which would be consistent with the dishes not drying at the end of the cycle. Possible causes include incorrect setting selected on control console (push buttons) or timer, heating coil disconnected from electrical source at one end or both ends, faulty control circuit inside the timer, faulty wiring between the timer/control circuit and the heating coil, burned or pitted contacts in the control circuit.

You need to use the service manual, work through, all the procedures, to isolate your problem,and repair. The DIY sites will also help

Also try to unplug and leave unplugged for 5 - 10 mins, and reconnect, this sometimes "Resets" it. Also it may NOT apply, but the Fix below regardless, works, many times, and is well worth a try.
Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

Does not dry dishes..still wet and spotty after cycle ..already have replaced control panel..now it reads HE


The reason it would not be drying is because either the rinse aid is low or the heater element is faulty. Not sure why you replaced control panel.

HE means the heater circuit is tripping. if you are using hot water direct from the tap then the water temperature could be too hot. If using cold water then the heater element could be faulty.

You can try some diagnostics if you are confident to do so. The details are in the service manual

LG dishwasher won't dry


Recommend you confirm that the rinse aid is not empty.
If problem persists and you are not getting an error message, contact LG service and pres them for the retrofit they released for the LDS5811 (and other models) that dramaticly enhances the drying ability. Until it is replaced, be careful because it is possible tht water will leak from the door panel (not directly from inside the diswasher, but through the door panel-based drying system.
Press them for a no charge repair for this problem and be persistant, firm but polite. If the agent is not helpful on their own, request to be "escalated" to his/her manager. Good Luck! and report back what you find. Thanks!

Model # dwu7702aae has heat delay light coming on during cycle. Why?


Heater is used to both heat water during clean cycle and dry dishes after wash cycle. Most washers have either a separate switch for Heat or Dry for optional use, or some have the water heat and dish dry options built into cycle set options.

You can save money by turning off the Dish Dry option since it is a very in-efficient way to dry dishes. Instead, open the wishwasher door after washing cycle completes, just enough so fresh air can get into, and humid air can escape, dishwasher.

Water Heat option is only needed for dried food on dishes, and is never needed if dishes are either rised off before putting them in the dishwasher, or rinsed off inside the dishwaser with a Rinse cycle, if they are to stand for a time waiting for a full dishwasher for wash.

Extremely long cycle


The drying coil that is broken also heats the water during the wash and rinsing phase. Right now it is waiting for the water to heat up, that's why it's pausing. Replace broken heater, they are relatively cheap and can be gotten at repair clinic.com.

Heater not working in cycle. No Error Code present


The LG 5811 dishwasher would display the error "tE" if the thermistor has failed. Not seeing an error could mean that the controller card (PCB) has failed. Hard to tell if the heating element has failed or wiring has shorted.
To look a little further, you can see (but not remove) the heating element by removing the filter in the sump area beneath the bottom rack. Disconnect dishwasher from power first and inspect for obvious failure of element.
Gaining access to the heating element is very complicated on the LG units. You have to drop the entire sump unit after turning the dishwasher over on its top.
Recommend a service call.

LG LDF6810ST Stainless Built In Dishwasher


It is very common that high eficiency, low water using dishwashers take longer to finish all cycles. The best way to "hurry" the washing is to make sure that the water heater is providing hot water of at least 120 degrees. But no hotter then 140 degrees.
If the dishwasher runs even longer, check to see is the dishwasher is actually connected to the cold water line. This dishwasher can be run from cold water but the water heating phase in the cycles will add much time ti the entire cycle.

This unit has a sensor that detects the detects the water clarity towards the end of the wash cycle. Rinsing the dishes may speed the load a little, but encourage not to go crazy on the rinsing because the dishwasher actually counts on the food particles to help clean the dishes.
Also, note that the final (third) blinking light means drying. You can simply open the door anytime after the final draining and power off the dishwasher, allowing the hot dishes to air dry.
Hope this helps. Please resply with your findings. Thanks!
