Maytag MHWE450 spins fine at full speed mid-cycle, for instance between wash and rinse, but will not spin after rinse or on "drain and spin" option. There are no error codes. Seems it might be a sensor or timer since it is mechanically sound enough to spin in the middle of a wash. Any way to reset without replacing expensive circuit boards?

Hello K.W. ,
Sad to sad their is no way to reset the control and yes it sounds as if has diagnosed it spot on ...since it spins on the rinse cycle the motor can be ruled out totally as the problem since its up to the control to tell the motor what to do and when to do it so if it spins sometimes and not others it seems to be the control that's not telling it to spin at the end. One thing to check though is that the filter screen perhaps is clogged since i believe it doesn't spin at high speed until after the water has drained and if the filter on the pump is built up w/debris its not going to drain fast enough so while it may not solve it,it may solve it by checking the drain filter. This tip i wrote will show ya how to check the filter on the pump.http://www1.fixya.com/support/r10121384-check_when_duet_washer_door_locked_after

If the filter is relativity clean and doesn't solve the problem the control baord would need to be replaced.
