ZWF 1021W & ZWF 1221!
Unfortunately it didn't work for me! I will have to call a service man thank you for your help!
I can see where the white chamber is, I had been trying to unscrew it but unfortunately i only have a very small set of pliers so I could not do what you suggested!
Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you questions ~ do you still need further assistance as I see Daniel has opted out?
