    • D
      David ParkerAug 16, 2025
      If your LG Dishwasher displays a DRAIN ERROR, it could be due to several reasons. First, try cleaning the filter. If that doesn't work, check the drain hose for any kinks or blockages and remove them. If the problem persists, the drain pump/motor or its circuit might be faulty, requiring you to replace the drain pump/motor or repair the circuit.

      Casey SmithAug 26, 2025
      If your LG Dishwasher displays an INLET ERROR, make sure the water tap is fully opened. Also, inspect the inlet hose for any kinks and repair them if necessary. Another potential cause is a clogged filter in the inlet valve due to impure water. To resolve this, close the water tap, unscrew the inlet hose at the inlet valve side, and clean the filter. If these steps don't solve the problem, consider replacing or repairing the inlet valve. Also, check for any water remaining on the base, inspect for damages, and disconnect the inlet hose to the dishwasher to unlock the safety valve.

      If your LG Dishwasher displays a HEATER ERROR, it could indicate a problem with the heater circuit, requiring you to repair the circuit. Alternatively, the thermistor might be faulty and needs replacement. A shorted heater can also trigger this error, in which case you should replace the heater. Lastly, the relay circuit could be the source of the problem, so repair the relay circuit.

      Andrew HarperSep 3, 2025
      An EXCESS ERROR on your LG Dishwasher suggests a problem with one of several components. The inlet valve may be faulty and needs replacement. The air break could also be the issue, requiring you to replace the air breaker. Another possibility is a problem with the sensor assembly, which would mean replacing the sensor assembly. Finally, the controller itself might be malfunctioning, so you may need to repair or replace the controller.
