Question about Washing Machines
This morning I switched on the machine after loading it. It half-filled with water, then started sending the message PE. I switched off and tried agaien twice but all I get is PE. I used the machine three days ago and had no problem.
Pressure sensor error. Cause: the sensor switch assembly is out of order.
Check the pressure switch -the system that determines correct water level in the drum.
If its giving an incorrect indication to the program timer machine will either overfill, refuse to fill or refuse to spin.
Its an air operated diaphragm switch triggered by rising air pressure induced by the entry of water into an airtight vessel attached to the base of the drum.
It tells the program timer that the water has reached the correct level, allowing it to proceed to the water heating stage in the cycle.
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 and a thin rubber pipe attached.
It generally sits just under the top cover. 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 machines have the pressure vessel integrated as part of the filter unit, with a pressure chamber moulded into the top of the filter body.
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 itself - 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).
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.
