LG Washing Machine Displaying Fault Code IE or 1E WM2016CW WATER INLET ERROR // Water not entering washing machine correctly
The manufacturer has assigned this error or fault code to indicate that the washer is not filling with water. Check to be sure the water supply valves are open. Also, check to be sure the water supply hoses aren't kinked or clogged. Next, remove the hoses from the washing machine and run water into a bucket to test the pressure and flow of the water. If all of these check out and you have good water pressure and flow to the machine, you should replace the water inlet valve.

u have a faulty electronic board,,,,,,,,,,,,front panel.

out of balance, could be the hall sensor

If its the main drum bearings gone then this will entail a complete strip to access them. The parts are available online, just have your serial no, model etc ready and trawl through various web appliance sites to find the best price. You will need a fair amount of mechanical / DIY knowledge to carry out this task. There are lots of parts and electrical connections.

Error Code PE mean Pressure sensor Error code
Check wiring connection to the pressure sensor; to solve it replace pressure sensor. The sensor repair is simple and straight forward.

IE. is inlet water valve error.

Make sure someone did not turn off the water to the washer!!!!

Remove fill hoses and check filter screens on washer and fill hoses and clean if needed.
If problem continues water valve may need to be replaced.

Is there any error codes? Do you have any lights coming on the front display?

check that switch for electrical connection. Perhaps a wire came off.
