Water fills the washer during spin cycle

I can not find your model number that you posted.
I can tell you that all whirpool thin twins up to last year were direct drive with no belt except for the dryer section. Whirlpool stackers from the early eighties did have a washer belt if yours is this old replace the entire machine.

Hello, try to checked the pump filter, and the pump is actually working. then I would suspect a draining problem.
If filter clean and pump works fine then it could be a control module fault. if this were the case, then it would probably be wiser to purchase a new washer.
Thanks

That could be 1 of a couple things.

1) During the agitate cycle... some water could've made it out of tub.

2) Possible Tub Crack (or overflow line)

3) Check your inlet lines

I would run it again watching it very carefully to determine if any of these are the problem.

You need to give more info in order for a diagnosis. Is this a compact stack unit or an all -in -one unit or an interconnected washer/dryer pair ? Is it front load or top load washer ? What do you mean by "dry cycle"? Is that dryer cycle or is it washer cycle without water ?
Usually when water cannot be drained it is a bad coupling connector on the motor drive, or a bad or clogged pump (small socks have been known to get sucked in an lodged in the pumps); in either case you need a good mechanic or a service person to handle the repair because it requires opening up the shell of the unit and getting to the motor/pump assembly.As always, disconnect the power cord before diving into the unit. Good Luck, Macgivor.

could be wash spin relay stuck in spin must be 15 years old

Replace the timer, you can find the product name model and serial number on two place. Either the back panel or on the lid underneath. Please rate if this helped thank you

No - the timer is the likely suspect.

check the pressure hose. a kinked clogged or disconnected hose continues to fill. the pressure switch senses the air pressure in the hose.awaiting your further comments. thank you.

most new washers have cold water only rinse and spray rinse ck cold water coming into machine during wash if no cold comes in suspect cold side of fill vale not opening ..could be wiring issue or a bad valve

The fault could be caused by several things, 1. it has a blocked air trap, 2.the lid switch is faulty. 3. The motor to gear box coupling has sheared off or the motor is faulty, there is nothing else that can cause this fault. Regards Engineer
