Does not complete the cycle or empty the water

It could be two problems. Check the hot and cold water inlet valves, it should be completely close at the final spinning cycle. Another thing is water outlet pump it should be run on the spinning cycle. Something might be stuck in the water pump.

I have had similar situation with my top load washer over the years. It has been the timer 3 times and the water pump 1 time.
How I came up with it being the timer. The knob which you set it on the type wash you want. Put it on a different cycle and see if it completes the wash cycle. example if my washer is not working when I put it on heavy wash cycle I might put it on the casual wash cycle. If you change the wash cycle and it goes through the complete cycle it is probably the timer which is part of the knob you change for different wash cycles with.
If it stops when it is time to empty the tub on all cycles it may be the water pump which empties the tub. The one time I had a problem with the water pump it was a small piece of coal had the pump locked up. I never figured how it got out of the tub and to the pump but I put it back together and it worked fine.
It should not go into the spin cycle if the tub is full of water.
Two of the timers I bought cost 40 - 60 dollars. One was 140 dollars I bought a new washer that time because the washer only cost 220 dollars.

It needs a new pump...

You need to buy a new control unit. I need more info!

see this possibles cause:
Water pre-heating
the water must be preating, is the water is cool, will have problem for a clean dish. see the water if hot
Cycle not completing
test this step, for timer ,if the timer is defective the cycle is not complete. see the diagram attached.

I am having trouble with water not emptying out of dishwasher completely help

if lid switch is good replace timer

sounds like its not going thru the complete spin cycle and empty could the timer control switch its all intergrated in one all the the different application s the cycles goes thru all report back to the timer control switch and when the cycle is complete the timer goes to the next cycle i f the timer is defective it well keep on going reguardless and go to the next cycle unfortunately the cost will run around 250.00 for the part good luck

running empty or full makes no difference. problem may be not draining to test this, put some water in appliance from a jug then start the cycle. (first action is to drain) see if water disappears. get back to me if you wish
