LG washer repair cost — here's what you need to know.
LG dishwashers are generally reliable, but when problems occur, knowing typical repair costs helps you make smart decisions. Here's what common LG dishwasher repairs actually cost, including both parts and professional labor.
Drain Pump: From $150
The drain pump is the most commonly replaced component in LG dishwashers. When it fails, you'll find standing water at the bottom of the tub and see error code OE on the display. The pump part costs From $50, with labor adding another From $100. This repair is one of the easier ones for technicians since the pump is accessible from beneath the unit.
Wash Motor and Circulation Pump: From $250
The wash motor powers the spray arms that clean your dishes. When it fails, the dishwasher fills and drains normally but dishes come out dirty. This is the most expensive common LG dishwasher repair. The motor assembly costs From $150 for the part, plus From $100 for labor. On older LG models (7+ years), this repair may not be cost-effective given that new LG dishwashers start around $550.
Door Latch and Door Seal: From $75
Door latch failures prevent the dishwasher from starting — it won't run unless the door is fully latched and sealed. Latch assembly replacement costs From $75. Door gasket (seal) replacement runs From $80 and addresses water leaks around the door edge. Both are straightforward repairs that keep your dishwasher running for years.
Control Board: From $200
The electronic control board is the brain of the dishwasher. Symptoms of failure include unresponsive buttons, random cycle stops, or error codes that don't match any specific component failure. The board itself costs From $100, with labor adding From $75. Before replacing the control board, ensure a professional has confirmed the diagnosis — many control board symptoms actually point to simpler, cheaper component failures.
Water Inlet Valve and Spray Arms: From $80
If your dishwasher isn't filling with water, the inlet valve likely needs replacement (From $80). Spray arm replacements are even cheaper at From $30 including labor. These are among the most affordable LG dishwasher repairs and are always worth doing. Spray arm issues often present as dishes on certain racks not getting clean — usually caused by cracked or clogged spray arm nozzles.
