LG WM3987HW 4.2 cu.ft. White Front Load Washer / Dryer Combo - Answered Questions & Fixed issues


LOUD NOISES IN washing MACHINE;

LOT OF THINGS TO CHECK, THE BELT LOOSE OR WORN, THE CLUTCH, THE TRANNY, THE BEARINGS BOTH TUB SEAL AND BEARING, THE REAR DRUM BEARING, the balance or counter weights.

THE DRIVE PULLEY- If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.
THE TRANSMISSION, THE MOTOR COUPLER, THE MOTOR DRIVE BEARINGS,
THE DRIVE MOTOR- If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.

The drive coupling connects the motor to the transmission and consists of two plastic drive forks with a rubber coupling between them. One of the drive forks is attached to the drive motor shaft and the other is attached to the transmission input shaft. As the motor shaft rotates, the rubber coupling between the drive forks absorbs the torque to prevent the forks from breaking. Normal use will create wear on the coupling and eventually the drive forks may slip and cause a vibrating noise. If the transmission seizes or if the spin basket cannot turn freely, then the coupling may fail and again you may experience a vibrating noise. Most models will require you to remove the cabinet to access the drive coupler. Disconnect power from the appliance before attempting any repairs.

A worn drive block will usually have a pounding sound, like hammering metal, during spin when it first starts. If there is enough interlocking tab left on the drive block, you'll see it finally engage at top speed with an empty basket.

In a transmission lock up the holes get enlarged in the rubber isolator and the studs break off the motor and transmission couplers. This is usually caused by the abrupt motor reversal between the agitate and pump out functions. If you hear a loud bang every time the motor reverses, the coupler is getting loose. An obvious sign of a failed coupler is a pile of black rubber shavings under the washer. If the motor runs and the agitate and spin functions don't work, the studs may have broken off the coupler (old coupler design) or the coupler may have broken at the shaft (new design) and you need a new coupler kit. The coupler can also just crack around its center hole allowing it to slip on the motor or transmission shaft hampering those functions.

If the washer is making a loud noise the drain pump might be going bad or might have something caught in it. Remove the drain pump from the washer and inspect it carefully. Look for anything that might be caught in it, a piece of wire, plastic, etc. If nothing is wrong with the pump, but it's still noisy it will have to be replaced.

Front load washers often use a self contained electric drain pump and the motor may be worn or damaged and require the complete pump to be replaced. Remove any foreign objects or replace the worn or damaged pump, thencarefully tighten the hose clamps and check for leaks before installing the cabinet or front panel.

All front-load washing machines have shock absorbers that are used to dampen the tub movement in the spin cycle. The shock absorbers or struts are attached to the base frame and to the outer tub and you will need to remove the front panel or the rear panel to access them. When shock absorbers weaken or become damaged, the machine will often make a loud banging sound during the spin cycle and if the symptom is not corrected, can lead to damage of other components. Inspect the shocks for signs of broken attachments, leaked fluids or a weakened dampening action and replace both shocks if worn. Remove power from the appliance before attempting this repair.

Some models of top-load washers use tub dampening straps to cushion the movement of the tub during the spin cycle. There are four straps attached to the top of the tub and to each corner of the cabinet

Also There are four suspension rods that suspend the tub and allow the tub to free float. If the suspension rods are noisy, there will be a squeaking noise during wash. You can fix this by putting bearing (lithium base) grease in the cup that each rod rests in. If it continues to squeal replace all four rods the cups come with the rods, replace them as well.

If your washer has a loud banging noise during spin the balance weight may be loose. This weight is to counter act the weight of the motor so you will find the weight directly behind the motor. Sometimes simply tightening the bolts will fix your issue but if the bolts are stripped out get some bolts slightly longer than the original bolt to allow you to put a locking nut on the bottom side of the mounting plate. If the weight is broken replace it.

Lastly Washer vibration can be caused by a broken counter balance spring. Ur washer may be equipped with one or more counter balance springs which help to absorb the natural movement of the spinning tub. If a counter balance spring fails the tub might lean in one direction more than another and it will shake and cause vibration.
By the way my advice is free cuz God is good!

GRINDING NOISES:

The plastic drive is known as a splutch (splined clutch). One problem with these washers has been loosening of the nut that locks the pulley to the agitator input shaft. If it gets loose, the pulley drops and the teeth no longer have good contact with the teeth of the splutch basket drive gear in spin mode. The solution is application of blue locktite to the threads of the input shaft. There have also been a lot of failures of the actuator that operates the cam ring of the splutch which raises and lowers the basket drive gear. It is raised for agitate mode and lowered for spin. There is a spring between the basket drive gear and the gearcase housing that maintains pressure on the basket drive gear. There are cams on the cam ring that ride up and down on cams in the splutch cam (housing) as it is rotated by the actuator thus raising and lowering the basket drive gear. The gearcase has a planetary gear set in it.

This dE error or fault code to indicate that the door is not latching properly. Check the lid or door operation to be sure it's not binding and that the door alignment is correct. Also, check the door/lid hinges to be sure they're not binding. Finally, make sure the door catch is in place and not broken. You may need to replace the door hook/catch or the door lock assembly.

There is no need to raise the water level. all modern washers automatically add the amount of water needed to wash the amount of clothes that you put in, I could explain how, but it will put you to sleep. rest assured these machines pretty much look after themselves. I would be more interested to know why you think it needs more water, are you having rinsing issues? wash quality issues?

Remove the screws that attach the top panel at the back of the machine, slide the top backwards and remove the top panel.
Run the machine as per normal, but be careful as the electrics will now be exposed, you will be able to see where the water is leaking from and be able to repair/replace defective part.

There probably isn't one. If you are certain power is getting to the machine, there may have been control failure.

LG WM Washing... | Answered on Apr 25, 2016 | 95 views


2 possible causes
the water solenoid control valve is split in the diaphragm and not stopping the water
the small hose from the base of the tub to the level control pressure unit is split or disconnected or the pressure unit has failed and is not activating the water control valve

Take out the soap drawer and clean the fabric softner compartment. This happens when there is residues left. And it gets clogged up.

LG WM Washing... | Answered on Feb 17, 2016 | 124 views


The obvious question is how do you know that it is soap? What washing machine is it? The biggest problem with most washing machines is that people use too much soap to begin with. I would go to a store and get a new t-shirt or something. Run the machine with nothing in it. Then put the shirt in and run it again without adding any soap. When it is done check the shirt for soap. There could be a build up on the inside of the drum.

Please do not do another load of wash until this problem is fixed, or you may find yourself with a house/apartment fire!
I am thinking your motor (most likely) or the controls (least) have a short, and are causing your problem.
Oh, yes.
Take a really good look at the circuit breaker box inside, because a broken or loose ground wire ( there are two) can also cause this problem.
One ground wire should be white, one should be bare.
Each should be securely screwed into the lugs of the grounded section of the circuit breaker box.
God bless your efforts.

pull back the lip and look for a wire and spring that goes around the gasket. check out repair videos on repairclinic.com or appliancepartspros.com.

more often than not, this is a problem with a faulty heater in the machine not getting it up to temperatre (which help the powder dissolve). Put it on a 90 degree wash and keep checking the temperature, if it's not getting hot, then you need to swap out the heater. Ift IS getting hot, then it could be an empty pump problem. If the pump or waste pipe are blocked, the wash will take a very long time but it will be struggling to evacuate water and add fresh, which will also causse powder residue to be left behind. But I'd put my money on a heater fault

something is blocking the pump.unplug first.take drain hose and hold down at floor level with a container to catch water.it may be a coin or a wire from a bra,hair bobble etc feel in the pump to see if the impeller is free to move.if it is then suspect something in the hose between drum and pump like a sock.that restricts flow enough to put up fault code
