My washer goes is working fine overall; however when it gets to the spin cycle, it's not spinning fast enough to get ring the garments out. It get the majority of the water out, but when it's finished, sometimes the garments are dripping wet. It is spinning, just not fast enough. It did this once before but just sort of fixed itself and started working properly again. I was hoping I could find out how to repair it and not have to get a new washer. Any suggestions?
