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.
