LM, the tool being used will need to be tapped firmly to loosen the bolt until it comes free. Otherwise, the lower agitator WP3951632 would need to be cut out.

Pedro, if the washer fills, washes and drains, but doesn't spin, Remove the cabinet and tub cover and check for an article stuck between the tubs and/or tub cover. If All's OK, check and replace the clutch 285785 and brake 285438 assemblies, it's probably worn out and slipping.

Sal, If the lower agitator is only moving one direction then the issue would be the transmission that is the issue. If the upper part is the issue then it would be the agitator dogs that is the issue.

Hello Linda, The agitator hasn't raised up but the inner tub has dropped. The spanner nut under the agitator has loosened and the tub has settled on the drive block, wallowing the center hole in the inner tub out too large for the drive block to properly support the tub. The drive block WP389140 and the inner tub W10389328 will probably have to be replaced to correct the issue.

Hi D.J. Block your unit up w a sturdy paint can or a couple of 4x4 wood blocks. Look up under the unit at the front of the pump. In the center area it is common that they begin to wear out through the front. Pump part # WP3363394. If you see the motor coupler has begun to wear out and there is black rubber and plastic parts under the center. The motor coupler is part # 285753A. Thank You.
