Check the pressure switch -the system that determines correct water level in the drum. Power off, drag machine out onto the floor, remove back cover and top cover. The pressure switch is a round item about 3 inches across with several wires connected. It sits under the top cover. Its an air operated switch which tells the machine water has reached the correct level. If its giving an incorrect indication to the program timer machine will either refuse to fill or refuse to spin. Disconnect the thin rubber pipe from the switch and blow down through it to clear any blockage. Switch itself may be faulty but its more likely the pressure pipe or the vessel attached to the other end of the pipe is blocked. Remove the pressure vessel, put a small nut or screw in it, fill it with water and shake vigorously till any crud or residue is removed. Refit all parts, check that joints and connections are water tight.
Also check the 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). Power off, drag machine out onto the floor, remove back cover or tip machine up at an angle. Locate sump hose, remove the tensioner clip by squeezing the tabs together with a large pair of pliers or vise grips, remove the hose, take out filter and clean. Be prepared for spillage of water. May help if the machine is tilted backwards at an angle.
