How do there Mark
Firstly welcome to the club.
Straight to second - I envy you owning a square door Bendix. One of thehe home economics rooms at secondary school had one of these machines and I made sure that the back desk, just in front of it, was mine. Such a quiet machine.
Model number wise, without a picture to know for sure, it could be one of a small clutch of models.
As far as I know, the longest lasting was model 7147. This came in two variants - 7147 and 7147B. The former has an all silver facia panel, whilst the latter had a brown and black stripe across the facia. There were also, at the very least, models 7122, 7125 and 7142 manufactured before the 7147.
The 7147B was the last of the square door bendix, before the new round door style was introduced.
All I can suggest is typing bendix 7147 (see picture below) or bendix 7147B (see next picture) into google and finding out just what spares are available (there will be someone on here who will be able to help more with the spares thing - unfortunately I am not very 'au fait' with that side of things).
You will be joining many people who are searching for Hotpoint Liberators - one of my personal favourites. The Zanussi machines you mention were models 1823 (cold fill only - 380rpm) and 1826 (hot and cold fill - 520rpm). The remaining Liberators were all pure Hotpoint design and are, in my opinion, are washing machine design classics.
Sorry that I cant be of more help re your search for a programmer/timer, but hopefully you will be able to confirm the modle number.
Cheers
Paul
(please post some piccies of your 'classic' machines - be great to see a surviving Square door Bendix)
