Repair Cost for LG Dishwashers
Typical LG dishwasher repairs fall between $140 and $480 dollars. Lower-end fixes involve drain hoses, door latches, or float switches. Costs rise when the circulation motor, diverter, or control board is involved. Repair data from parts suppliers shows that LG control electronics tend to cost more than average, which pushes some repairs higher. LG dishwashers are known to be quite reliable, which paired with their low energy use and sustainable manufacturing practices makes them one of our picks for the most sustainable dishwashers.
Common Issues
Technicians often mention wash motor failures, broken diverter assemblies, and sensor malfunctions as the main reasons LG units come in for service. These failures show up across the standard, QuadWash, and front-control families. Owners frequently report that diverter problems cause poor spray rotation or long cycle times, while sensor faults lead to incomplete cycles or random stops.

| Repair Type | Common Symptoms | Typical Total Cost |
|---|---|---|
| Circulation motor | Weak spray, loud humming, poor cleaning, long cycles | $350–$480 |
| Diverter assembly | Poor spray rotation, water aimed incorrectly, long cycles | $240–$330 |
| Control board | Random shutdowns, no start, inconsistent cycle behavior | $360–$480 |
| Door latch | No start, door not recognized as closed | $120–$180 |
| Float switch | No fill, immediate drain at startup, false water level detection | $120–$170 |
| Drain hose or clog | Standing water, slow draining | $140–$200 |
| Sensor failure | Incomplete cycles, random pauses, misread water temperature/level | $180–$260 |
These figures reflect realistic U.S. averages for LG dishwashers from the last decade including labor.
Labor Time and Difficulty
Most repairs take one to two hours. LG dishwashers pack several functions into the lower assembly, so reaching the motor or diverter usually means removing the unit from the cabinet and separating the sump. Extra time is sometimes needed for diagnosing intermittent sensor readings.
DIY repairs are reasonable for spray arms, drain filters, and basic hose issues. Work involving the diverter, motor, or control electronics is better handled by a technician. Lift-and-tilt mistakes are common on these machines, and incorrect reassembly can cause leaks that show up days later.
When a Repair Makes Sense
If the dishwasher is under eight years old and the failed part is mechanical rather than electronic, repair is usually the sensible option. Once multiple sensors fail or the control board shows recurring issues, replacement becomes more practical due to long-term durability concerns.
