Hello,
My 3yr old LG dishwasher gave an IE error about 2 months ago. My research showed this is a water inlet issue....so I changed the Inlet valve and the washer worked great for 3 weeks. It then died again with the IE error, I thought maybe the part was bad so it was replaced and worked for 2 weeks only this time....again the IE code is back
Symptoms are as follows....turn on the washer it starts with the drain cycle for almost a full minute, then it tries to add water. There is a faint humming for 30 seconds but no water comes in. The machine chimes loudly and flashes IE error on the display and all four lights flash on the front panel, then the draining sound starts again but no water goes into the washer and the IE message just keeps on flashing !
I tested the inlet valve and it has a resistance of 1150 ohms well within the specs, so I really doubt the valves have been faulty. I carefully checked all the wires for damage (problem on some LG washers) none appear to be damaged. The water flow is strong, and the valve is not plugged.
My though is maybe the main board is not sending a proper signal....but I don't know how to test that or what else it can be. Ideas?
thank you in advance!
