LG Dishwasher: not filling with water
What is this symptom?
Is your LG dishwasher not filling with water? This common issue may present as a cycle starting without water entering the tub and can often trigger an error code like IE. Several factors could cause this problem, including a shutoff water supply, a clogged inlet valve, or a faulty float switch. Understanding these causes can help you troubleshoot effectively.
Important Tips for LG Models
- LG dishwashers may show an IE error code when no water is detected, which specifically points to water supply/fill issues according to official support.
Possible Causes
Water supply shutoff or low incoming water pressure
How to Identify: Ensure the water supply valve to the dishwasher is fully open and confirm there is adequate water flow from the source.
Part: Household water supply/valve
Clogged or faulty water inlet valve
How to Identify: Dishwasher runs but no water enters; mineral debris may be visible at valve mesh or valve fails continuity testing.
Part: Water inlet valve
Float switch or water level sensor fault
How to Identify: Dishwasher thinks water is present or misreads level; float stuck in raised position preventing fill.
Part: Float assembly/water level sensor
Kinked or blocked fill hose
How to Identify: Visual inspection shows a sharp bend or debris blockage in the hose between supply and dishwasher.
Part: Fill/gateway hose
DIY Solutions
