Washer repair

My washer will fill,wash and drain fine. When it gets to the rinse/spin cycle it will not advance. If I spin the dial to final spin and press start button it will begin to spin out but then stop and the rinse and spin lights flash Any ideas?

Since it will work through one whole wash cycle with no problem, this suggests the problem is not mechanical but instead is a problem with the control unit.

Try changing it out and see if that fixes it. If you buy from this site and the part does not fix the problem you can return it, so there is little risk here.
