I have an LG Dishwasher Model LDF7810BB. I have no response at all from the control panel, no lights at all, no error messages - completely dead. The unit worked quite well for 2 years, then just quit. I have good power at junction box. I have taken the unit apart, tested the line filter box on the R of the dishwasher (actually jumped it). No response. Thoughts? Allan.

NEED TO SORT OUT LEAK FIRST AS THIS HAS ACTIVATED YOUR SUMP LIMIT SWITCH. THE CYCLE WILL NEVER PROCEED OTHERWISE.

If you have confirmed power to dishwasher, you are pobably looking at a control board. I have only run into this one time on a LDS5811 so far. Parts on LG dishwashers have a two year warranty. You have to dissassemble the door to replace the part.

It doesn't work at all If your dishwasher doesn't work at all, check these:

Power from the house Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.

Door switch The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.

Wiring Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.

Timer or selector switch Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.

SOURCE: LG LDS5811BB Dishwasher

Some of the LG LDS5811 had problems with the wiring harness in the door panel. This is nothing to mess with unless you have disconnected the DW from power.
You can open the door panel by removing the screws around the inside edge of the DW. Or, better yet, firmly but politely contact LG service and tell them you are aware of LDS5811 dishwashers having these symptoms being caused by _melting_ wires in inside the door panel. This is true and even if the DW is out of warranty, LG should fix this problem at no cost to you.
Good Luck!

How do I fix a CL error code on my LG dishwazher

The CL indicates that the control panel (or child) lock is active. The method to toggle the lock on and off depends on the dishwasher model. For most LG dishwashers, either press and hold the Rinse and Spray buttons or the Dual Zone button (if the dishwasher is running a cycle) for 3+ seconds.

Please add a comment with the model number of the dishwasher if you want the specific CL toggle option for your appliance. The control lock is useful when you clean the control panel. It also keeps a child from altering the cycle or starting the appliance when it should be off.

I hope this helps.

Whirlpool DU1055XTSS dishwasher is totally dead as if it were unplugged. No response from front lights. Only 3 years old. Another post for an different Whirlpool model says it's the thermal fuse, but I...

Hi,

If you have power going to the dishwasher, meaning the breaker, switches, wiring and fuses in the home are okay, the most common cause for your symptoms is the thermal fuse.

The thermal fuse is a small disk shaped device that is behind the control panel on the right side it is snapped on to the electronic module. The part number for your model is W10258275

LE error message on the panel

Depending on the serial # of the dishwasher it may need a new wire harness and inner door liner.

LE is a motor circuit error.

Contact LG @ 1 800 243-0000 they may help you out.

2H accures in digital read out. NO Cycles start, just a humming

Do you own an LG LDF6810ST dishwasher? If not, please reply with the manufacturer name, model and serial number.
Are you saying that the display that normally shows the time is displaying an code of 2H? On an LG, that means 2 Hours, (120 minutes) and is not an error code.
On an LG with a symptom like this, I would arrage to replace the main processor card (PCB). You would be getting an error message if the motor (wash or drain) had failed.

LDF7810BB LG dishwasher won't run

Confirming that this is an LG LDF7811 (which happens to be black) ... What you are seeing is a error code "tE" as in thermal error.
(The mentioned drain error would be "OE" as in Outlet (Drain) error.)
First check (with a thermometer) the inlet temperature of the hot water. If it is greater than 140 degrees, turn down your water heater to no less than 120 degrees and retry.
If problems persist, the problem is probably the thermister.
If it is not a failed thermister, then the controller card (PCB) needs to be replaced. Neither are easily changed and I urge you to contact LG service for repair. (See your manual for the number)
Good Luck! and please report back with what worked.

My LG dishwasher keeps stopping on the wash cycle ond shows FE on the control pad.

Hello again annasgsds,
An FE error code signifies "excess error" meaning excessive water is supplied ..more than normal.. possible cause are the inlet valve ( which I made reference to in my previous response of the controller itself is damaged or defective. In either case.. LG recommends to replace the inlet valve or the controller once diagnostics are completed and you've identified which of the two components may be at fault. Could be either but before replacing the control card, I would remove and clean the inlet valve to see if that was clogged or dinged up and unable to fully close.
Regards,
Rick
