My PAF-1260PX has functioned well for 26yrs. Rarely have I cleared the lint filter. Yesterday the wash cycle ran OK, but on start of rinse there was a hum, but no pump action and so no water left the machine. I don't know what fixed this problem, but I did the following:
siphoned out the water, removed the back panel, took out the pump. There didn't seem to be anything stopping the pump from rotating. I cleaned the interior, and applied rust converter to the rusted metal exterior. I cleaned minor corrosion from the various electrical terminals. I cleaned the lint filter. After putting this back together the machine functioned normally...to my surprise. I was concerned that I might have needed a new electronic module (circuit board), and found on the web a company in Melbourne called Module Repair Service.......if ever you need one of those that could be an option.
