The technician that fixed this problem for my machine opened the housing by the pump and cleaned the sensor that controls the pump. It had gunk and fat on it. I'm looking for a workshop manual so I can do this my self, any advice on how to find one?

F4 fault is a draining problem. Probably a blockage in the drain pump but could also be a faulty pump or the drain hose is kinked & stopping the flow.
