Model fwt645rhso will agitate but won't drain out, on spin cycle washer spins one way, stops goes back the other way, but water will not drain out. Does not rapidly spin on final cycle. Any suggestions?

Quite often the problem with spin cycles is that the cycle cannot start until a sufficient amount of wash/rinse water has drained. So what will often happen is that the washer drains, the cycle starts, a lot of water comes out of the clothes, it stops, waits for the water to drain, then restarts. If the drain pump or drain lines are restricted or blocked or the pump is faulty, the unit may never achieve spin cycle.

What is the complete model number of your unit?

Sorry if it may be too obvious, but have you checked the philtre? generally they stop spinning when it's stuffed... when you open it, make sure you have a mop and bucket handy, some water will come out!

see this causes and fix it. God bless you
Motor Coupling If the washer won't spin or agitate the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission.

Drive Belt If the washer won't spin or agitate, check the drive belt. If the belt is broken or if it isn't tight on the pulleys the washer won't spin or agitate properly.

Drive Motor If the washer won't spin or agitate the drive motor might be defective. This is not common. Check all of the other related parts to this symptom before replacing the motor. If the motor is visibly burned out or physically damaged, replace it.
Stator Assembly If the washer won't spin or agitate the stator assembly might be burned out. The stator is essentially one half of a motor, it interacts with the tub by creating a strong electro-magnet. If the stator burns out the washer won't spin or agitate. Check the stator for continuity. This part is often misdiagnosed.

Door or Lid Latch Assembly If the washer won't spin or agitate the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Door Lock Motor and Switch Assembly If the washer won't spin or agitate the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.

Motor Control Board If the washer won't spin or agitate the motor control board might be defective. The motor control board provides power to the motor as well as direction and force. If the motor control board is defective the washer may not work at all or function properly.

It sounds like the transmission is done. Can't pinpoint what it is exactly, but I would start there.

Sounds like the brushes are struggling to get enough power to the motor to spin. Renew motor brushes

Hi

If the cycle won't complete then either it's a problem with the timer or a cold-water supply problem:-

If your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer.

It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water.

WASHER FILLS WITH WATER, THEN WON'T AGITATE. TURN KNOB TO SPIN AND IT DRAINS THEN SPINS. STILL WON'T AGITATE please show me a diagram

Hi
Try these things first.
1) Verify a circuit breaker isn't tripped
2) Advance the timer control dial slowly 360 degrees-
If the washer starts spinning, then we know the motor and drive belt are fine but that there is something wrong with either the timer control dial or the agitator solenoid. Call in a professional for this.
If the washer doesn't budge, then verify that the drive belt(s) is attached and not broken by removing the back panel. If the belt is broken, replace it. If it is loose, then tighten it by loosening up the bolt holding the motor and moving it on its swingarm (much like a car alternator) until there is a 1/2 to 3/4 inch deflection in the belt. Some washers use reversing motors. It's possible the motor works on the spin cycle but not on the wash cycle. If so, call a pro.
3) Visually inspect the lid safety switch- Is it loose or cracked? If so, the washer might work intermittently, stopping at different cycles.
4) Check motor and drive belt- Remove the main access panel (usually in the back). Is the motor spinning, but the drive belt isn't? If so, then you have a drive belt problem. Go here. If the motor isn't spinning, then go here for washer motor troubleshooting.
If none of these tips resolve the problem, then there's probably a more serious problem with either the motor, the transmission or the agitator itself. If this is is the case, call in a pro.
