SOURCE: LG front load washer wont drain and makes loud

Sounds like the impeller has come off the pump motor shaft. If you push it back on, it will just fall off again. You will need to replace the pump motor. Let me know the model number you have if you'd like detailed instructions on how to replace it. (instructions are a bit lenghty, and I'd rate the repair about a 6.5 or 7 on a 1 - 10 difficulty scale.)

If your washer won't drain, check these:

It spins, but doesn't pump 
It doesn't spin or pump
It pumps, but the water returns
It spins, but doesn't pump If your washer spins but doesn't pump the water out, the drain line is probably clogged. In many washers, a small sock or other piece of clothing can get between the clothes tub and the outer tub that holds the water. If the clothing gets between the tubs, it may then get into the drain hose that's attached to the pump--or even into the pump itself. If it's in the pump, you need to remove the hoses from the pump and pull the item out.

To remove the sock from the outer tub port, open the washer's main access panel and remove the large-diameter rubber hose that connects the pump to the bottom of the outer tub. Then, using needle-nose pliers, try to grab and remove the clothing through the port. 

Sometimes you can't remove the stuck clothing from below. Then you have to remove the agitator, top of the outer drum shield, and inner clothes tub. This isn't easy to do--and you may need special tools--so you might be happier getting a qualified appliance repair technician to do the job.

If the drain line isn't plugged, the problem may be with your pump. Even if the pump appears to be turning, the internal impeller may be broken. If so, you need to replace the pump.

It doesn't spin or pump If your washer doesn't spin or pump water out but the motor is running, your washer probably has a frozen pump pulley. If so, you need to replace the pump. To check the pulley, remove the pump from the washer and try to rotate the pulley manually. If it doesn't turn freely--if it's frozen or stiff--replace it. 

It pumps, but the water returns If the water that pumps out of the machine goes back into the machine after the spin cycle, your washer may be siphoning the water from a laundry tub that has a slow drain, back into the washer. The usual remedy for this is to improve the draining of the laundry tub. (Is something stuck in the drain?) Also, check for these problems:

  • If the drain hose reaches more than about 4 inches into the laundry tub, cut off the excess.


  • If your drain hose is lower than the washer's cabinet, install an air gap/siphon break assembly.

The pump is clogged with most likely a coin. You need to get access to the pump then remove the hoses.(Make sure you put a pan under the hoses to catch the water) After that you should be able to remove the objects.

SOURCE: wont spin and makes a buzzing noise in all cycles.

This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.

First, see the Sears parts site for your washer:

http://www.searspartsdirect.com/partsdirect/getModel!retrieve.pd?pop=true&modelNumber=110.26912691

and you'll see a list of major sub-components with diagrams and parts.


The Kenmore / Whirlpool top load uses a reversing motor to initiate the pump for draining and the transmission to spin.

Since the washer will drain the problem is not in the Lid Switch (which tends to happen quite often with these washers)

The problem does however point to the Neutral Drain Assembly.


This is a Whirlpool PDF on how these washers operate. It has a detailed section on how the transmission works.

https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/f7e2147fa98b28cf85257122007475cb/$FILE/L-55.pdf

Those cams/gears etc. in that assembly keep the washer from spinning until all of the water is pumped out and then go into spin mode.

The buzzing sound that you hear could be the small cams in the assembly trying to connect with the main spin gear.

Ours had basically the same problems.

After looking at the transmission parts list (available on a number of sites) and on the Whirlpool site (Whirlpool makes Kenmore) we noticed that the one of the cams in the neutral assembly which is supposed to have a small spring, didn't on ours when we tore the transmission apart again

http://shared.whirlpoolcorp.com/assets/pdfs/literature/Repair%20Part%20List%20-%20W10114743.pdf

Found the part number for a kit (Whirlpool part number 388253 Neutral Assembly) for $15.00 and replaced the cams and gears.

In order to get the transmission out, you have to remove the cabinet, the fabric dispenser and both agitators. The top agitator uses a plastic 1/2" drive bolt (a 1/2" socket extension works well).

You don't have to remove the drum.

See the following for how to access the transmission.

http://www.american-appliance.com/catalog/newsdesk_info.php?newsPath=16&newsdesk_id=137

Lay the machine down (after disconnecting power and hoses, remove the pump (two clips), the motor (two screws hold two clips on the motor), lift and set the motor aside.

Remove two 1/2 inch bolts for the motor mounting plate and three 1/2 inch bolts for the transmission.

Pull the transmission, remove the clutch (there is a spring clip that holds the clutch on the main agitator shaft), remove the 8 screws carefully the transmission holds 14 - 15Oz of oil, remove the clip holding the main spin gear on and check the plastic cams.

If the cam that should have a spring doesn't, or the others look damaged, or the main spin gear is damaged the washer won't go into spin mode.

If that's the problem, install a Neutral drain kit, put everything back together carefully and the problem may be solved.

As an aside, fixing ours cost less than $30 including 80-90 weight gear oil vs. $170 for a new transmission.

I have an affinity washer and dryer. The last loand did not complete its cycle. It is partially full of water, but not enough to seap out. Itmakes a buzzing sound and will not spin. It is not the type of...


It sounds like the drain pump has stopped. If it still has water in it and you turn it on (in the spin only cycle) the drain pump should be running and you sould be hearing the water drain. The washer will not spin until the water is out. Depending on how handy you are determines whether you can access the drain pump and remove the obstrustion. There is also a trap to catch debries from going into the pump. This could be plugged, but normally you don't hear a buzz. You hear the drain pump working but no water going out. Good luck

My lg washer and dryer wm3431hs isn't draining. I took of the hoses in the back, cleaned the filters and still nothing please help!


Hi

If the washer is not draining then it is due to a clogged drain pump or a drain filter or a kinked drain hose. To resolve the issue you'll need to clean the drain hose, inspect if the drain hose is plugged. If the hose is fine, then remove the front kick panel and access the drain pump and filter, if you are unable to find the pump and filter remove the back panel as well and trace the drain hose to the bottom of the tub. There is a drain filter connected with the drain pump. It usually gets clogged, and needs to be cleaned every 6-8 months or so. The drain filter is a small white filter connected to drain pump with a hose. If it still doesn't work then you'll need to check the connections of the drain pump, check the electrical connections with a multimeter. If it still doesn't work then you would need to replace the drain pump. Hope this helps...

Makes buzzing noise and won't spin or drain


Sounds like something is stuck in the drain pump.  If nothing is stuck in the pump replace the pump.  It won't spin until it drains, so fixing the drain problem will fix the spin.  You can get at the drain pump by taking off the bottom panel.

Why will my washer not spin or drain water promply. it also make a slight buzz noise which occurs if the power is on or off


there is air leakage in the line of pressure switch. so water level rises to higher level to make required pressure. as water is more in your washer it won't drain properly. the sound is that of air leak.
