LG Dishwasher Repair in Philadelphia

To repair an LG dishwasher well, you start with the hardware: LG dishwashers combine QuadWash spray arms with a direct-drive inverter wash motor, and TrueSteam cycles appear on many models.

Our LG dishwasher jobs mostly come down to check valve or drain pump faults, water in the base tripping the leak sensor, failed door latches, and board errors following a leak. The calls we get tend to mention leak error showing AE or E1, water in the tub with an OE error, and top-rack dishes coming out dirty. Water has reached the leak sensor in the base when an AE or E1 code shows, so check for overflowing suds from the wrong detergent or a cracked tub seal. When a dishwasher will not start, the door latch switch is checked before the control.

LG's direct-drive wash motor rarely fails, which means poor cleaning almost always comes from a blocked spray arm or a clogged filter. Ordinary dish soap can set off a leak-sensor code just as easily as a genuine leak, and the code will not clear until the base pan is dry. A control board that dies after a leak is usually collateral damage, so the water source needs fixing during that same visit.

Rental turnover near the universities means a dishwasher often runs with the wrong detergent or none at all, which leaves residue and clogs filters. The door latch, inlet valve and drain-hose loop explain a lot of dishwasher complaints, so they are checked before we quote.

The check valve or drain pump faults and repairs like it are quoted in writing before we start.

Look through the spray-arm holes occasionally and clear any blocked ones with a toothpick. Calls about water in the tub with an OE error are a good example of why we diagnose LG dishwashers before ordering anything.
