Zanuussi IZ141S Wash M/c Pause light Flashing?

Hi,

Machine fills for short period, stops, then fills again to about 1″ below lip
of drum. Sometimes will then start filling again to about 1/4 way up the
glass and then the start/pause button light will begin to flash and machine
stops.

At this point the wash, rinse and spin lights are all illuminated.

Sometimes will fill to the 1″ level then agitate for a while then begin to fill
again to 1/4 way up the glass door and then stops as above.

This stop and start filling has nothing to do with the clothes absorbing
water. The machine is the sloping front type. I think the high level the
water is reaching, is too high and is going into fault mode. I have not
seen many of these machines before nor this kind of symptom.

Is it to do with maybe air leaking from the pressure switch. Has anyone
had this before.

Many thanks,

Laurence
