The jets on the tub do not shut off at the end of the cycle

First of all, what you have is a WOW pump that has an E-switch for a control.
There is a knob on the top lip of your tub that you turn a 1/4 turn to turn this pump on/off.
There is a small circuit board inside the box on top of the motor. This is likely the source of your problem.
Here is your biggest problem. That little circuit board is not made anymore. We have the e-switch but you will be better off changing out the pump (which you have to do anyway) with a new WOW pump with an air switch and change the switch on the top lip of the tub to an air button which will turn the pump on/off.

The door seal has to be in a proper position completely around the door (including the bottom area of the door). If not, it will leak. Also, there are two black corner baffles/seals (located in each front corner inside the tub area) that may also be the culprit. Additionally, there may be an issue with the float switch assembly that shuts off the water supply prior to the wash cycle. If the float switch assembly is allowing an extra amount of water in the tub, it will cause a leak.

There is a water pump in the machine which pumps the water out of the outer tub and into the drain, after the wash and rinse cycles.
It is possible that this pump isn't working properly. I think if it weren't working at all, you wouldn't be able to get beyond the wash cycle.

It has been my experience that small articles of clothing may get washed or spun out of the inner tub and into the area around the pump pick up, thus partially blocking the flow to the pump.
It's also possible that the drain hose from the pump to the drain may be partially clogged.
It is also possible that the pump doesn't run sufficiently long to get all of the water out because its' motor gets hot and shuts down or because of a problem in the control mechanism which manages the the starting and run time of the pump.

First, I would unplug the washer from the wall outlet and probe under the inner tub, or possibly remove the tub to see that there is no blockage from clothing.
It's also possible that things left in clothing pockets like paper clips, small plastic items, etc. can get into the pump and lock up the impeller.
If you're sure it isn't blocked you can then run a "short cycle", no load and water only, and watch to see how much water comes out of the discharge hose where it's hung on the drain pipe.
It should gush out, and tub should be free of standing water prior to the start of the first rinse cycle.
If it does not, then you'll have to access the pump and clear it of obstructions or replace it, if defective.

As it drains, it should start spinning slowly, then speed up as it drains; the final portion of the spin cycle is very fast.
Essentially, the spinning tub wrings out the clothes using centrifugal force.

With the water remaining in the bottom of the tub, it would appear that it is:
a) not spinning long enough, or
b) there is something preventing all the water from getting out in the time allotted by the timer to perform this task.


A fair handy man can get to pump either from the rear of the machine with back plate off, or by removing the cabinet cover from the frame, depending on the model of the the machine.

As always - before attempting any repair, UNPLUG THE UNIT!



When clothes are wet at the end of a cycle, check these:

Motor coupler
To test the motor coupler, re-start the washer in its spin cycle. Let the machine run for a minute, and then open the lid and notice whether the tub is spinning:
If it's spinning when you lift the lid, the coupler is fine.
If it isn't spinning--and your machine was produced by Whirlpool®--you may have a broken coupler. Many Whirlpool-made washers use a small, relatively inexpensive device called a motor coupling. This plastic-and-rubber component is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. When that happens, you need to replace it completely.

Spin cycle
If the washer doesn't reach its proper spin speed, the clothes may be too wet at the end of a cycle. Check to be sure the load is properly balanced and run a spin cycle again. If the clothes are still wet, you may have a worn or loose belt (Maytag®), a worn clutch (GE®/Hotpoint®), or a worn motor pulley or tub bearing. Replace the applicable component.
Alternatively, there could be clothes caught between the inner and outer tubs. Read the "It spins but won't pump" section of the "It won't drain" section. Also, there could be other things that cause friction on the drive train. Seek the assistance of a qualified appliance repair technician.

Siphoning
If the water that pumps from the machine goes right back into the machine after the spin cycle, it may be because your washer is siphoning the water from a laundry tub with a slow drain, back into the washer. Try to improve the draining of the laundry tub. (Is there something stuck in the drain?) Also, be sure the drain hose doesn't reach more than about 4 inches into the laundry tub. If it does, cut off the excess.

Water-inlet valve
Water-inlet valves eventually fail. One problem that may develop with a water-inlet valve is that it can no longer completely shut off when the electricity is turned off to it. Then, the valve may leak and drip water into the clothes tub--you may notice that your washer has water in it when you haven't used it for a few days. To fix this, replace the valve.

Is unit getting proper power(check circuit breaker panel ,mayby unit was never turned on).Unit may not have beed installed properly.If unit usees button on top of unit check check and make sure air hose is connected at both ends, at button and at control unit.

This is normal for jets on hot tubs/whirlpools for the jets to shut off after 20 minutes. This is a safety feature to prevent overheating of the water. When jets are running, the hot tubs are constantly heating and can elevate to dangerously high temperatures excess of 110 degrees causing scalds that you would not even know are happening. Your body temperature acclimates to the climbing temps and you dont realize it is that hot. It also helps prevent you from falling asleep and not paying attention to the temps in the tubs. Sorry, but I think you are going to have to restart the jets after each cycle. It is a safety feature that can't be bypassed or circumvented. Good luck and happy tubbing

you might have an air lock, when you first start filling the spa, start the water running in the skimmer first. that should force air out of the pump and should pick up prime right away. if not, you may have a valve problem.

Depending on how mechanically inclined you are, take apart the tub and clean everything out. No easy task, I know, but who want old dog hair floating around? That will be your best bet.
