filter - generally located behind a panel at the foot of the machine.Some are obvious like little square hatches and some are hidden behind the trim panel at the foot of the machine. Once panel is removed the filter should be visible. Its generally a circular plastic fitting which unscrews in an anticlockwise direction. Some hotpoint, indesit and ariston filters are located in the big black sump hose (the one that leaves the bottom of the outer drum and connects to the pump). Remove the back cover, locate hose, remove the tensioner clip by squeezing the tabs together, remove the hose, take out filter and clean. Some machines have no filters at all which allows all manner of junk and debris directly into the pump which is of course, bad news.
