If you’re not a fan of disposable plates and cutlery, washing dishes is one of those mundane tasks you’ll have to endure in the absence of a dedicated mechanical or organic dishwasher. Mechanical dishwashers are more reliable, efficient and convenient than the organic kind. Your husband, wife, or kids are more prone to complain when given the task of dishwashing; the mechanical gets straight to work. That is of course, until your wonderful LG dishwasher rebels and defiantly displays a “LE” error. There is no way of wishing this error away, you will have to call a repair tech or fix the problem yourself. Thankfully, an “LE” error code is not as complicated to remedy as you may think. As with most home appliances, common repairs are usually simple. As a precaution, always turn off power to the appliance before any repair or troubleshooting and only use original LG dishwasher parts if replacement parts are needed.
An LG dishwasher displaying an “LE” error code is informing you there is something wrong with the dishwasher’s motor. The motor is either working abnormally or has failed. There are several reasons for this, the most common being a problem with the wires connecting the motor, the impellor of the pump being blocked, the motor’s rotor having seized, or the blade being jammed. You will have to ensure proper continuity of the motor’s wiring, unblock the impellor, rotor or blade, or replace the dishwasher’s motor, pump or PCB. Many LG dishwasher owners report faulty wiring as the cause of their dishwasher’s motor error. Faulty wiring therefore, should be the first problem to investigate.
There should be two white and two grey wires connecting the motor to the dishwasher. The grey wires connect to a float switch and the main circuit board. The white wires connect to the circuit board and an electronic filter. If one of those wires has a poor or severed connection, the dishwasher will fail to operate and the “LE” error will persist. If a wire is severed, correcting the problem by replacing the length of wire yields the best results. In some cases this may not be appropriate. If you cannot replace the wire, you can repair it by splicing a new piece of wire. Make sure you protect the splice with either shrink wrap or electricians tape.
You will want to protect the wire against any future damage. The main cause of wire damage is thought to be mechanical wear during dishwasher operation. When the dishwasher is operating - it vibrates, and some internal parts will move slightly. If the wires are too tight, improperly positioned or inappropriately protected, dishwasher vibration will gradually generate the same problem. Wire may be vulnerable to mechanical wear which would account for why so many LG dishwasher owners suffer the same problem.
If you cannot see any obvious signs of mechanical wear. You will have to check the continuity of the full length of wire. A basic home multi-meter will do the job sufficiently. As soon as the wires have been checked, move on to inspect the motor, pump and blade. Each should easily be turned by hand, if the impellor, motor or blade has seized it will have to be replaced. LG parts are sometimes difficult to find but there are reputable part suppliers that sell parts for LG washers, dryers, dishwashers, and other LG appliances. If no problem can be found with the wiring, motor, pump or blade, there is possibly a problem with the main circuit board. Check for any condensation or signs of overheating. Most times, such PCBs cannot be visually checked – it will have to be checked professionally or replaced completely.
