Over Filling
TOP SITE!
My 10 year old Zanussi built-in machine recently started overfilling. A new similar machine looked like setting me back £500. Having read washerhelps faults pages it looked like I was looking at a pressure system problem. Having unplugged, I took off the top of the machine. Using washerhelps description, i located the pressure switch, removed the switch and hose, gently blowing into the switch I could hear it clicking and was pretty sure the actual switch was working. I checked the hose and that appeared to have no holes.
I reconnected the lower end of the hose, where it sits just above the pump and again gently blew into the hose, hoping to unblock any gunk that could have been blocking the system.
I then re-connected the switch & hose and started a short wash, bingo, NEW LIFE!!!!!!!!! Danced around the kitchen for a while then thought I'd drop you a line to say thanks for the excellent site.
Thanks again.

Zanussi built-in washing machine overfilling traced to pressure system blockage
- The problem
- A 10-year-old Zanussi built-in washing machine started overfilling.
- Likely cause
- The pressure system was suspected. The pressure switch appeared to operate when blown into, and the hose showed no holes, so the strongest supported cause is a blockage in the pressure hose/pressure chamber area rather than a failed switch.
- What fixed it
- With the machine unplugged, the top was removed, the pressure switch and hose were located and checked, and the lower end of the hose near the pump was gently blown through to clear a suspected blockage. After reconnecting the switch and hose, the machine ran a short wash normally.
- Checks to try
- Pressure switch removed and gently blown into; clicking was heard
- Pressure hose checked and found to have no holes
- Lower end of the pressure hose near the pump was blown through to clear a blockage
- Short wash cycle tested after reassembly

Thanks Dave. Here are the links for anyone else that might need them. Although I had to give up answering specific repair questions because of time constraints there's a lot of free information still available covering the basics.
