I have a zanussi jet system 1200, model wjd1257w. It is a washing and drying machine. It leaks water, I guess at the spin cycle or perhaps before it. I searched and found out that it could be either due to loose connection of the pipe to the gasket or the door seal itself needs to be replaced. I could not find that for doing it at home should I open the top and front panels all, or just I can do it by working around the front door?
