I have an Admiral 20 lb. capacity heavy duty washer, not sure what model. Machine gets to spin cycle, spins and drains water from tub, Once water is drained, tub stops spinning. There's no power to motor from timer switch, Timer switch seems to not be moving, don't hear any ticking from it as I do when in between wash and spin cycles.

Nice old style machine. I think the motor has a two speed control on those. Low speed does wash and high speed does spin. There is some help in this link.

call a local repair service either the pump is gone or the line to it is plugged with perhaps a sock

There should be a module that does the agitation bit for the washer motor(Spins one way shuts off and reverses the spin etc) There may be a capacitor under the control panel that is not working any more so the motor will not start.

It won't drain 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.

check your lidswitch. do you hear it clicking when you raise and lower the lid.

Normally yes. There are around 12 to 20 gallons of water in the tub after the wash cycle, which will be anywhere from 63 to 110 pounds of weight in addition to the weight of the clothes. For the machine to start the spin cycle to remove this water would place a heavy load on the motor, gearcase, pullys, belts, gears, ect. With the water drained, the load is lighter, and much easier to start spinning the excess water out of the clothes. The normal cycles are: Fill, Agitate, Drain, Spin, Rinse Fill, Agitate for rinse, Drain, Spin Cycle and off. Imagine trying to spin a 5 gallon bucket of water over your head, full of water, and then empty. Which one do you think would be easier to do? And safer for you.

The spin cycle should be on a timer,and shouldn't be able to change how long it spins.The same timer that controls all the cycles of your washer.Your pump may be trying to go out,and isn't removing the water fast enough.This will keep water in the tub,and the normal spin cycle isn't long enough to let the pump get the job done.Another problem might be a clog in your drain hose.Another problem could be the drain hose is set to high above the pump,and the pump can't push it up that high (shouldn't be a problem if you are using the hose that came with the washer,and not extending it with another hose or something.)

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

Motor coupler
Spin cycle
Siphoning
Water-inlet valve
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. 

Check to make sure your lid switch is working.

broken or slipping drive belt, ( motor) to spin pulley , losse pulley, defitive drive clutch, spin brake fails to release, or transmission is frozzen
