My washer will not spin after a heavy load of towles????

check that the concrete stableliser on top of the drum has not come lose or try to fill the washer with a full load and not just a couple of heavy items like a few towles or jeans eric

There must be the correct weight in a washing machine. If it is under loaded then the drum will spin out of balance because the weight is trapped to one side. regualar use like this will break the drum bearings.
Weighty things like towles & sheets have to be balanced around the drum prior to spining, that's why the drum does slow and quick spins to even the load out. apart from that one of the drum supports need attention.

The washer is likely detecting an off balance load with only a rug or two. You may want to try and put more rugs or old towles in to offer a counter balance to alleviate off balance condition. Or, you may consider washing the rugs at a commercial facility. They really are hard on the residential machines, especially if they come apart or the backing comes off.

Sounds like the motor. Motors work in two directions and one direction can die while the other one works.

Looks like you have low voltage or a defected run capacitor problem.

had trouble with some washers not dumping water found penny screws and other small material in the pump removed and worked o k .this might help.hum might be from restriction in pump.

there s a"button trap" located on the side of your pump assy, behind the lower acess panel ( youll need to remove 3 torx 20 screws from the from bottom of machine ) after emoving the panel oull see the clean out directly in forn t of you. BE WARNED THERE WILL BE WATER behind that acess point grab a towle!!!!
cloges with debris and such preventing good draining!!

you need a new transmission it will slowly get worse until it stops working

REMOVE DEBRIS FROM PUMP LOCATED INSIDE WASHER ,, REMOVE 2 SCREWS HOLDING BOTTOM PANEL,, PUMP IS PLASTIC TURN COUNTER CLOCK WISE AND REMOVE DEBRIS,, BE CAREFULL HAVE ALOT OF TOWLES STILL HOLD 3 GALLONS OF WATER

You need to have you belt replaced. Over time the belt will strech.
this causes the dryer to still spin but the belt will sometimes loose the grasp of the drum and cause the belt to spin only.

This happens because over time with heavy loads of towles and jeans pull down on the drum as it is being loaded. Than when in cycle the jeans will drop from the top to the bottom pulling aginst it even more..
