Code ie machine fills with water but does not spin.

An IE error code signifies that the washing machine is filling with water slowly or not at all. This can occur when water supply taps are not fully open or the water pressure to the tap or house is too low. Other possible causes are kinked, pinched or bent water line hoses, or clogged water inlet filters.
TIP Make sure the water taps are fully open.
Make sure the hoses are not kinked or pinched. (Use caution when moving the washer.)
Clean the inlet filters.
Check another faucet in the house to make sure your household water pressure is adequate.

The IE or 1E error or fault code indicates 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.

The "IE" error code indicates that there is a water inlet problem on an LG washing machine. This code appear's if the washer will not fill to the correct water level. There are 3 possible causes for the IE code.
1) partially or fully closed water supply lines
2) improperly attached supply hoses
3) clogged supply hose filters (on machine and in the hoses).

Water inlet error - washing machine failed to fill
The fault code is displayed, if the washing machine does not detect any incoming water.
·Check wiring to water inlet valve
·Check water valve
·Check drain pump
·Check pressure switch
Check PCB

The IE or water inlet error or fault code is 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.

Error code of "IE" signifies a water inlet error.

This means that your machine is not filling to the proper water level, and may be fixed by ensuring that machine's water supply is properly connected and turned on. Also, this means that the washer has not filled with water in 8 minutes.

Hope helps.

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.

IE is inlet error. (failed to reach set water level within 8 minutes)
You have cleaned the inlet screens. Make sure there is water up to the inlets. (disconnect hose and put end into drain or a bucket and turn valve on to make sure) Re-connect hoses and turn valves back on. Make sure hoses are not kinked. If still no water fill, you should take the top off the machine (bottom screws on the plastic retainers on the back side of the top, then from in front of the machine, push back with a sharp push of the palms of your hands on the L and R side of the top, to push it back about 2 inches, then lift the top off) and then check to see if you are getting any power (120 volts AC) to the water valves when you start a cycle. (Again, you should not get code IE for aprox. 8 minutes) No power to at least one coil on water valve = bad control board. Power to at least one coil, but still no water fill = bad water valve.
(by the way, the LE code is a capital L and E)

What is error code?
Does unit spin?
Does unit drain?
Does unit fill on all water settings?
Ie set to hot, warm, and cold and see if fills.

The sensor you are referring to could posslbly be the water level switch which controlls the level of water,and also. is a factor as to wether the washer will spin or not, it also is part of the heater circuit, so it has numerous functions.
I t can be found at the top right front of the washer, and is about 3" in diameter, and has a thin plastic tube going to it.
it could be sticking, there is no sure fire way of testing it properly, but you could try tapping it and blowing down the tube, it may solve the prob.
Hope this helps.
Plz rate my solution.
Thanks.
