I called in a repair technician who diagnosed that foreign materials had made its way into the pump and had destroyed it. We had to pay for the service call and the additional cost for the repair was more than 50% of the cost of a new washer. Buying a new washer seemed the best choice but that meant dumping a whole lot of scrap into a land fill. Washer models seem to update daily but the chat line provided the right part number and the part was not that expensive. The repair was quite easy. The irony is that after the replacement I took out a bobby pin and some jean material from the pump. The impeller was not damaged and the pump ran without a problem. I now probably have a perfectly good spare. Why is there not a strainer on the pump? I know techs have to make a living but it seems like there is a better way.
