My old dryer was taking too long to dry clothes. Purchased a new one. Two weeks later same problem. I have since learned that I wasted $550 on a new dryer. A local lady had put in a post. Remove filter, hot water will not pass through it ! ! With the use of dryer sheets,it has to be scrubbed with a brush and soapy water. Clean filter is all the instructions say. Expensive lesson ! !
