Quick summary
Check power and that the door is fully latched, then the control lock (CL). If it starts then stops with IE, the issue is water supply.
A dishwasher only starts with the door latched, the lock off and power available. Then water must arrive within a set time or IE appears.
Unplug the appliance, close the water tap if there's a leak, and never open covers that need tools or expose wiring or circuits.
Possible causes
Control lock on
CL appears and stays on even after power cycling until released per your manual.
Door not latched
Items obstruct closing or a rack isn't fully pushed in.
Power
Socket, breaker or cable.
Water inlet problem
Closed valve or kinked hose (IE).
Board or door-latch fault
Needs testing.
Safe checks you can do
- Check the socket and breaker.
- Close the door firmly and ensure nothing obstructs it.
- Release control lock—on many LG models hold two buttons for 3 seconds (see your manual).
- Make sure the valve under the sink is open and the inlet hose straight.
- Unplug for a minute and try again.
When to stop checking immediately
- If the plug or cable is hot or damaged.
