LG washer high pitch noise when water enters at beginning of cycle

What could be the cause of a high pitch noise at the beginning of the wash when the water is first entering the washer? There are no error codes in the display, and everything else seems normal.

Two possibilities: the water is coming in under pressure through a solenoid valve that is not fully open or the pressure pump is whining on its bearings.

Sounds like you need to replace the HALL sensor.
(On a scale of 1 - 10 in difficulty, I'd rate this repair a 3.5) It is part number 6501KW2002A and is covered by a seven year part warranty (motor and sensor covered). (warranty may not apply to products purchased at Sears, but part is not all that expensive anyway) No labor coverage after the first year, but it is rather easy to replace.
Unplug machine. Remove back cover (4 screws). Take off nut in the center and remove the rotor, which is just a metal "can" with permanent magnets on the inside. Remove grounding wire and wire clamp. Remove bolts with 10 MM wrench allowing you to take off the electric coil thing. Unplug the sensor, un-clip it from the electric coil thing, and replace.
The new HALL sensor has heavier components to help prevent a re-occurrence of the problem.

SOURCE: Squeal when water first sprays at beginning of cycle

Turn off your water supply valves and remove the water lines one at a time. Shine a flash lite in the water valve and see if the small screens are plugged with debris. These can be removed with needle nose pliers and cleaned. Replace and try it again. If the noise continues you need a new valve.

SOURCE: TROMM WASHER WM2277HW LG. GET IE ERROR AT BEGINNING OF WASH CYCLE

That noise means it is blocked. Did you get the filters in the back of the machine at the inlets? I've been through heck with this.... check out what finally worked.

IE= Inlet Error. I have struggled with this problem. After much trial and error it appears that it is due to my well water. People who have city water will probably not have this problem with this machine. Well water or hard water buyers beware. This machine is VERY much a primadonna princess capable of stopping your rinse cycle at the slightest imperfections. This is the Princess and the Pea of Washers... but I have a series of possible solutions that will have you appreciating her primadonna superiority once again.

Troubleshooting... Listen.... Does she sound like she is struggling and no water is coming in? If so then it isn't. The cycles will last forever as she makes all sorts of grunting noises. Something is preventing the water from coming in. It could also be that the pressure in to the washer is under 55 psi.

a. I have adjusted the pressure in the pumphouse to allow for minor fluctuations so that the machine will have at least 55 psi.

b. Take off the hot and cold inlet hose and clean the screen at the back of the washer. The two screens are supposed to come out of the male receptacles. They are fragile... beware. I use a squirt bottle/atomizer to clean these screens as mine chipped and will not budge.

c. You can add a screen just off the faucets so that you don't have to move the machine each and every time you get an IE error. This helps but does not solve.

d. I installed a faucet filter that I bought from Home Depot in the PVC sprinkler's section. They are made of a black plastic material and can easily cross thread, so be careful. They look about the size of a one liter container and unscrew midway to reveal a removable cylindrical mesh filter. This makes it possible to widen the surface area where tiny particles can be trapped without totally blocking flow to the inlet sensor. :-) When installing this make sure to completely rinse the hoses, and all screens coming into the machine. I took the shortcut first and thought my idea had failed only to discover that the screen behind the washer was partially blocked.

e. Periodically remove the filter and clean. Depending on the quality of your water, you may need to do this at all the points that have a screen.

I now have a screen washer between the sprinkler system filter and hose and the one that comes installed inside the male ends of the inlets for the water hoses. This has helped enormously.

f. Another possible offender is the soap and softener dispenser. To remove and clean press down on the plastic toggle piece on the soap side, the whole drawer should slide off and clean. Non-HE detergents and softeners can create a buildup of gooey gunk. Just clean it. Inside the drawer space you can clean to increase flow. I use baby wipes.

g. Make sure that the filter on the bottom is free from obstructions. If there is water in the drum, you will be flooded if you remove. This is a last resort after all the inlet lines have been cleaned and cleared.

Note: It doesn't take much to lower the flow of water to the point that this machine will not run. Since you cannot override the computer on it to run a spin cycle or even advance to remove water it can be highly frustrating. I've learned to obey my machine and just clear every last possible inlet.

Best of luck.

Hello Anne, welcome to FixYa.

I understand by your post you have an LG washer, that in your words "makes a high-pitched scream whenever the water is coming in", correct ?

If that is the case and indeed it is an LG WM2442 (if not please post with the correct model...though it should have little difference on the problem and solution) I would focus on the fill hoses and specifically the screens inside the valve itself.

This is what I mean, most times a scenario like this is due to insufficient water flow...not a strong enough stream (making a hio-pitch noise eminate from the valve)...I'd suggest you remove the fill hoses and check and clean the screens in the valve.

example:

macmarkus_915.jpg

**Some fill hoses also have screen at the inlet end of the hose...where it connects to your home taps so check there as well**

Let me know what comes of this or if anything is not clear and I will continue to assist you going forward if necessary. Should this fail to remedy the issue, it will need to be determined if it is just during the hot fill or cold and replace the related valve.


Thank you for choosing FixYa and good luck. Please keep me posted as to how you make out before going forward if you feel unsure.

Regards,

Macmarkus :)

I have a LG model no LD-2040WH dishwasher that is troublesome at the moment. During the washing cycle, it gives a very high pitched screeching noise. It has now displayed an error code E1. I have take


The problem could be the washer motor bearing. LG motors have the impeller unit coupled to the motor and the water seal between the motor and impeller is a problem. The drop of water that leaks ends up on the bearing and it eventually gives problems. This can be seen by close inspection of the front bearing for slight rust indications .They use poor quality bearings but replacing the bearing is easy BUT you need to replace the water seal as this is the cause of the problem. Unfortunately the water seal is part of the plastic impeller unit and must be replaced. Not necessary to replace the whole motor as the bearing is easily replace and cheap. (the noise made by this fault is more of a slightly high pitch grinding / whine)

Hi, I have a frigidaire front load washer, model FTF2140ESO, that is making a high pitched screeching noise when it enters into the final spin cycle. The noise ramps up in volume as the drum spins faster....


Some times screws can work their way out near the drum and rub against the drum causing the squeak. You might have to take off the back of the washer and see if there is anything loose contacting the drum.

High pitched noise


This is a water pump about to blow, or a clogged filter or hose. The fact that you hear it immediately, and limited water level is involved, it's pretty much your bingo.
After turning off the water supply, unscrew the garden hose-like attachments for hot and cold water intake. There is sometimes a small filter right there where the water enters. If they're clogged, clean em.
Take the hoses and run them through an outside plug to make sure they aren't clogged with back flowed dirt from the filter and hard water.
If it still won't fill, you'll need to test the pump.
each machine is different, but if you follow the hoses from where your hoses enter the machine, you should be able to unscrew them at the other end.
Stick them in a deep bucket then turn on the machine and see what the pump does. Is the noise coming from it? (service or replace). Does water gush out of the pump into the bucket? (clean all hoses and filters, buy some machine grease and lube all the moving parts, including opening the water pump and giving it a generous amount of grease.
Put it all back and your squeal will one way or another be gone and you'll have plenty of water

High pitched noise during hot water only


This problem is usually caused by LOW water pressure going in the washer.
1. Remove hot water hose and flush all debree from water line.
2. Change water filters and you'll be good to go.

GOOD LUCK!

LE code on lg washmachine


The LE error code means that you have a motor problem.  The high pitched noise means that the motor sensor has failed and needs to be replaced.  You will need to call a qualified LG technician to replace the sensor.

Sounds like the water seal is damaged and the leaking water has damaged the top bearing which is just below the water seal. You will need to have the hub & seal kit replaced.
