Zanussi washing machine overfill problem

[rich crocombe]

My Zanussi FL 1032/A has started overfilling.When filling with water,the
machine does not shut the water supply off, and continues to fill
causing severe leaking ! Can anyone advise how the fill shut-off
works,and what can be done to cure the problem ?
Thanks

We had this problem with our Hotpoint. The solution lay in desludging
the pressure switch pipe and chamber.

On the hotpoint a pressure operated switch tells the controller to turn
off the inlet supply at defined level. The arrangement consists of a
tube feeding a chamber which contains a dyphragm and micro switch. The
rising water seals the open of the tube and as it continues to rise the
air pressure in the circuit increase until the switch 'makes'.

Upon inspection the pipe and chamber were blocked with dirt and soap
powder etc..

hope this helps

All the best

There is usually a water level switch, connected to the drum, normally
through a pipe. Suggest you check it is functioning properly.

Hi,
I'm out on a limb here, and others may give better advice, but on
washing machines there's a water-level switch which works on air
pressure against a mechanical switch.
Switch off the power (pull out the lead too) and take the back
off the machine. Look for a small (8mm diameter or so) plastic
tube emanating from low down on the machine and travelling up to
a gadget about the diameter and shape of a shoe-polish tin.
As the water enters the machine, it travels up this pipe and compresses
the air above it. At the top, the large-diameter sensor gets enough
pressure to work a switch. If the tube is ruptured, the water
valves are kept open and the switch doesn't tell the controller
that the machine is full of water, hence the valves are held open...
Note that no water will get near the switch - it's all done with
compressed air.

To test the switch, disconnect the lower end of it (no water in the
machine, lest a flood!) and blow GENTLY down the tube (it's not a
breathalyser - it works on tiny pressures and too much will damage it).
If you blow "enough" you oughta hear the switch clicking.

If all else fails, nip down the library and borrow Graham Dixon's
very-excellent "Washing Machine" manual (published by Haynes of
all folk!).

Hope this helps

P.S.: my reply to your email address failed somehow.

I would assume it is just a solenoid, probably clogged with limescale.

Our 5 year old Servis started doing this and it was jammed with crap.
I replaced it to find the problem still existed intermittently, it turned
out to be a loose spade connector on the way down.

I don't necessarily recommend it but whenever I now encounter these
connectors I tend to solder them in place as they do seem to work loose on
some machines which aren't very well balanced on their spin cycle.

A friend had a similar problem, his machine, according to Philips Service
Engineer, was caused by too much water pressure which caused the valve to
give up after about 3 years.
I am however doubtful of this explanation, but it bears considering.

No, I think Mungo's is absolutely on the ball except ...

...it may be a significantly different shape on others. On our Hoover it
was more like a mis-shapen tennis-ball. Odd that, because I happen to
know that Mungo also has experience of Hoovers...

You are all on the right track, the pressure chamber which is attached to
the pump manifold is liable to be blocked with limescale/gunge.
Isolate machine from mains, tip machine backwards,protect motor and pcb from
water ingress, remove the hoses from manifold. remove filter door.
Unclip manifold from base of machine, slide drain pump assy out to left,
noting position of o ring, carefully remove manifold from machine,
unclipping pressure hoses from manifold and loosening wiring from clip.
At this point you need to clean manifold thoroughly (not easy!).
alternatively replace manifold assy (easy!) normally available for about
15ukp
Reassemble in reverse order, It's generally a good idea to remove pressure
hose and clean through as this is also liable to be blocked.
Good luck.
