LG Slow Inlet Valve Seepage or Backflow

Water remains in the bottom of the tub between cycles, slowly seeping in when the dishwasher is off.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Water inlet valve not closing fully, Backflow from sink drain, Siphoning due to low drain hose

Safety first: Turn off power and close the water supply valve.

Check for backflow: Ensure the drain hose has a proper high loop or air gap to prevent sink water from flowing back into the dishwasher.
Test inlet valve: With water supply OFF, bail out the tub completely. Turn water supply ON without running a cycle. If water slowly appears in the tub, the water inlet valve is leaking internally and must be replaced.
