SOURCE: What does PE mean on my LG washing machine

Check the pressure switch -the system that determines correct water level in the drum. If its giving an incorrect indication to the program timer machine will either overfill, refuse to fill or refuse to spin. Its an air operated diaphragm switch triggered by rising air pressure induced by the entry of water into an airtight vessel attached to the base of the drum. It tells the program timer that the water has reached the correct level, allowing it to proceed to the water heating stage in the cycle.

Power off, drag machine out onto the floor, remove back cover and top cover. The pressure switch is a round item about 3 inches across with several wires and a thin rubber pipe attached. It generally sits just under the top cover. Disconnect the thin rubber pipe from the switch and blow down through it to clear any blockage.

Switch itself may be faulty but its more likely the pressure pipe or the vessel attached to the other end of the pipe is blocked. Some machines have the pressure vessel integrated as part of the filter unit, with a pressure chamber moulded into the top of the filter body. Remove the pressure vessel, put a small nut or screw in it, fill it with water and shake vigorously till any crud or residue is removed. Refit all parts, check that joints and connections are water tight.

Also check the filter itself - generally located behind a panel at the foot of the machine.Some are obvious like little square hatches and some are hidden behind the trim panel at the foot of the machine. Once panel is removed the filter should be visible. Its generally a circular plastic fitting which unscrews in an anticlockwise direction.
Some hotpoint, indesit and ariston filters are located in the big black sump hose (the one that leaves the bottom of the outer drum and connects to the pump). Power off, drag machine out onto the floor, remove back cover or tip machine up at an angle. Locate sump hose, remove the tensioner clip by squeezing the tabs together with a large pair of pliers or vise grips, remove the hose, take out filter and clean. Be prepared for spillage of water. May help if the machine is tilted backwards at an angle.

If you take the top of the unit, you will find it strapped to the side of the chasis about level with the top of the drum. Ots white and round, about the size if a child's palm. YouMAY find that removing the unit, blowing down the plastic feed pipe and then putting the unit back fixes your problem. My personal experience with these things though is that once they fail they call all sorts of problems. Very nice of your machine to warn you. It's not unusual for these things to fail in a manner that just tells the machine that there's not enough water and they just fill and fill and fill until water comes out of your soap drawer!

Needless to say therefore, if you do remove and refit, or even if you buy a new one to fit.... WATCH the machine for the first couple of loads and make sure that it's not under or over filling before you walk away and leave it to its own devices.

Hi from retired Englishman in SW France,
LG's 'de' stands for 'drain error'.

I would gently suggest as a first step that you clean the drain motor/pump lint tray/filter. So many 'faults' are caused by blocked filters and many machines will not even go to rinse or spin or release the door lock if there is any water still left inside.
Following are my complete and hopefully 'coverall' pre-typed guidance notes for checking both the drain motor filter and the drain motor ;-0)
REMOVE POWER AND ENSURE YOU HAVE A WATER RECEPTACLE/RAGS TO SOAK UP THE WATER WHICH IS BOUND TO POUR OUT (alternatively use a wet vac as sensibly suggested by VinnyB1234!)
If you are unsure where the filter is, it is often behind the front lower (kick) panel (or in some machines at the rear in an awkward position!). These panels are either held on by (plasic) screws or will just pull off. Most filters are held in by a round cover/knob. Sometimes the filter will not come out with the cover and you will have to persuade it to come out to play.
It's surprising what people have found in theirs! It is always worthwhile checking it on a regular basis.
Now- whilst the filter is removed it is normally possible to see the drain motor and ensure it is not jammed by a foreign object such as a needle or a toothpick. It should be able to be turned by hand/finger- the power IS OFF!
At this point it is also possible to test if the motor works. No clothes or water in the machine, select a spin cycle and put the power back on. You should be able to see the motor turning at some point, possibly straight away. Using something suitable like a glove see if it is easy to briefly slow the motor down. If it is easy then the motor is malfunctioning.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

SOURCE: PE error for LG Washing

Hi from retired Englishman in SW France,

LG's 'PE' does indeed stand for (water) Pressure Error'
(following is pre-typed!)

If you have checked that the hot and cold water taps are turned on fully and the hoses are not kinked or squashed at the back, it is worth while checking both the hot and cold water inlet filters. Turn the taps off and remove both hoses at the washer end. Inside each inlet port there is normally a little filter which should just slide out. Clean if necessary and replace each one and the hoses. If after turning the taps back on there is no improvement, the problem is symptomatic of a malfunctioning hot or cold water control valve. Sorry but it needs a service call and a check that it isn't the control PCB ;-0(

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck,
John C

SOURCE: Dear expert of LG WF-F783PC (washing machine). i

Possible that the inlet flow is low , check the inlet valve and filter. Also try using the manual settings and if all the cycle works well then it is possible that the fault is with the controller unit or a possible errors from the level controller or the inlet valve.
It is best to remove them , check reset after cleaning.

Lg wf-t1022tp gives a PE error code.


Try this first before replacing any parts or disassembling your LG washer:
- Unplug the washing machine for 1 minute.
- Plug the washing machine back into power.
- Restart the wash cycle.
- The washing machine may now have cleared the PE error code, if not see below...

You will need to check the wiring harness that connects the water level pressure sensor to the main control board.
- Check for a loose wire harness, a damaged wire harness, or a burnt faulty wire.
- Check that you get continuity through the wire harness by checking it with a multimeter.
- If the wire harness from the water level pressure sensor to the main control board is found to be faulty, replace it.
- If you get continuity and the wiring harness is securely connected to both the water level pressure sensor and the main control board, then proceed to the step below...

- If you found the water level pressure sensor was caked with debris and you have cleaned it, replace it back into the washer and run a test.
- If the washer runs without the PE error code displaying, the washer is fixed and the PE error has been cleared.
- If you find that the water level pressure sensor is faulty, remove it and replace with a new OEM part.

Replacing the water level pressure sensor simply involves locating the sensor in your LG washer. Remove it from the washer and replace it with a new genuine LG washer part. Test washer to be sure the PE error code has cleared and the washer is now working properly

Check the pressure switch and hose. Pressure switch is what turns the pump on and off. Trouble is usually in the hose so check it first. Look for the hose to be unattached or clogged.
