Called to above tumbe dryer which is showing the following. When prog is set the drying indicator lights and machine runs then after 20 secs the anticreasing/finish indicator lights and it gives 4 bleeps, and appliance cuts off. Ive bench tested pump and checked float switch which was clean as a whistle, . The stat on heater is open circuit but even shorted out makes no difference maybe it closes on heat. Any ideas guys
