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
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 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). 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.

SOURCE: i have whirlpool top loader
In my research, the PE error relates to the fill level of the washing machine. The fill level sensor is a pressure operated device. There is a sealed air line that goes from the bottom of the tub to an air pressure sensor. As the tub fills, it compresses the air in this air pressure sensor. When the tub is filled to the level selected on the dial, the sensor stops the fill cycle.
This air line can be plugged or the sensor itself can be faulty. This air pressure sensor is usually located near the top of the tub just under the top cover. If you can locate it, disconnect the air line from the pressure sensor and blow through it - it may be blocked by lint and soap from several washing cycles. There may be a filter in this line to help prevent this blockage. But the filter may have become blocked itself.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
