Tub won't spin

Check your cogs. Pull the top off agitator off and look inside.
Depending on model has different typed of cogs that slide and catch when working properly. The do wear out.
Also known as "dog ear cogs". Very cheap parts. $2.

I would call the washing machine engineer for a quote as we have no spare parts on this site eric

I would start by checking the belt on the motor could be slipping when u put full load in washer. also check that pulleys are not loose.

You will need to check for an article of clothing stuck between the basket and tub that may be partially blocking the drain hole.

My parent's Hotpoint did the same thing!! The brake on the bottom of the tub is not engaging! It needs replaced!!

Lid switch If the lid switch is defective, the washing machine may not agitate or function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to replace it.

I suspect you definitely have a clutch problem. It might be the liner or it could be the transmission seal leaked some oil into the clutch you would know it by the oil on the cabinetThats a hint of a clutch problem with leaky top seal. An easy fix.the newer washer have a square recess you unscrew and lift the top of the agitator off and then you have access to the bolt that holds the lower portion on. The agitator has to come out first then drop the tranny
(3 bolts) Put the tranny on a bench. You can use a pair of pliers and squeeze the spring and the clutch liner comes right out. You can buy just the liner, no need to buy the kit but you can do that too. None of the parts are expensive and anybody can do these repairs.

That's great, that leaves me to believe that it's the timer. I would recommend replacing it.

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. 

The tranny should either spin or agitate not both
