Will not spin water stays in and wont drain the tub wont spin and when you try to jiggle the knob it is derad on the spin cycle

If your drain is not high enough the water will siphon out while filling. Check your owner's manual for correct height, usually about 39 inches from ground

Check your timer. Jiggle the selector knob,then move it to a position just prior to the spin cycle, see if this helps.

check that ALL of the water has been pumped out you could have a partally blocked drain pump causing the water level pressure switch not to be satisfied that the tub is completly drained. If tub is NOT completly drained it wont spin but it will usually give you an error code try drain spin to see if that works draining it a second time

The water-level switch regulates your washer's fill volume. This switch is usually a diaphragm device with a small, clear tube attached between the switch and the bottom of the washer's outer tub. As the water level in the tub increases, the pressure on the air in the tube increases. When the pressure reaches a certain level, it activates the switch, shuts off the water, and signals the timer to begin the agitate cycle. If the switch is defective, it may prematurely signal the water to shut off. If so, you probably need to replace the water-level switch.

It won't drain
If your washer won't drain, check these:
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.

my old hitachi washing machine PAF-760P was not used for a long time.I started yesterday, it started washing but when the knob rotates and goes to drain the water,it only clicks and does not drain the water. What must be wrong with it. can you help please.

ok turn off unit at power switch, turn knob to drain and spin, and turn back on that will reset its programming and force it to do the drain and spin cycle also check the drainage hose to ensure it's not kinked or clogged. If it's clear and in good shape

THE MODEL NUMBER IS USUALLY FOUND SOMEWHERE AROUND THE OPENING OF THE TUB OR ON THE LID ITSELF

Hi I fixed the problem by removing the filter at the bottom right hand corner of the washing machine and removing 2 x £1 coins that had got stuck there

As the machine goes through the cycle, it should do what is called a neautral drain (drains water without the tub spinning) then a momentary power intreupt allows the gear to slip down and the spin begins. If this is not occouring on one cycle, it is usually a bad timer.
