I'm looking for a repair manual for a Admiral Designer Series model# 6443 Heavy Duty washer. The main timer/operation switch has gone bad, and I may be able to find a replacement for that, but then I'd need to see how to dismantle the top of the washer. When I do a search for just the exact model number and manufacturer name on this website, it tells me to refine my search to just the exact model number and manufacturer name. Thanks, digi
