Drain machine by running the outlet pipe into a bucket at floor level or run the outlet pipe out of the back door if it'll reach. Check the filter unit for blockages. 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 with a set of heavy pliers or vise grips, remove the hose, take out filter and clean.
Check the pressure switch -the system that determines correct water level in the drum. Its 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. 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.
Some interlocks prevent the door from opening if the drum is moving. The mechanism that detects this is called a pecker unit and it is located around the motor pulley. It connects to the interlock via a cable assembly. If the pecker unit is broken in the "on" position it may be preventing the interlock opening. Visually check and try to activate the mechanism by hand.
Other interlocks have a secondary locking system which ties in with the pressure switch. If this system is faulty - caused by blockages in the filter, pressure vessel or the thin rubber pipe running to the pressure switch the machine "thinks" its still full of water and wont allow the door to be opened. Take off the top cover, examine the interlock from behind and detach any rubber pipes or cables to try to open it from inside. If all else fails, the interlock itself may be faulty and will have to be broken open. A replacement interlock unit and/or catch will of course be required.
