HI.. My hotpoint WF320 washing machine will not go into final spin. The wash enhance and on/off lights flashes. The washer goes through the wash as normal, completes rinse and spin but as soon as the final rinse starts the drum stops spinning. We have checked the waste water pump, cleaned all the pipes, checked the brushes and they are fine, checked the pressure sw, it seams ok when you blow into it?? I am now at a loss.............please help!!1 Thank you in advance!!!
