Have a pe code what do I look for?
Answer CT Green,
The PE error code is a pressure sensor failure. You will want to check the pressure switch and if it checks bad then replace the pressure switch.
I've had to replace the water inlet valve in my LG washer three times in five years. Why is it malfunctioning so often?
Unfortunately we would not be able to tell you the reason it fails so rapidly. It could be anything from getting higher than normal voltage to the part, could be a water pressure issue or the valve getting clogged with sediment from the water lines.
