Important Tips for LG Models

  • LG dishwashers can stop mid-cycle when sensors detect improper closure or water issues; moisture in control panel has been reported as leading to erratic stopping.

Possible Causes

Water inlet valve malfunction or water supply issue

How to Identify: Cycle stops after draining then fails to fill with water; possible buzzing from inlet area; insufficient water in tub at stop.

Part: Water inlet valve / water supply hose

Clogged filter or drainage blockage

How to Identify: Standing water visible when cycle stops; dishwasher stops due to inability to drain properly; slower progress before stop.

Part: Filter assembly / drain hose
