AquaCycle
I was expecting you to say it was an Aquacycle, hence your user name!
The Jetsystem must've been top of the range then i think yeah. Don't think Zanussi had a digital machine during the time this machine was made. They had the Computawash (FLE3000) like has recently been on Ebay, which was mid-late 80s, but i think the first digital machine to follow it was the IZ machines with the tilted drum in or around 2000/2001, so your Jetsystem mustve been top end at the time.
Did it have RSI? Ive noticed some of the Jetsystems of this era (with the white control panels & buttons with coloured strips on them) don't say RSI on them, but others do.
How was the water level on it? Ive used the next generation 'Jetsystem Excel' in a rented flat but it was really tight on water, hardly used anything. And i never noticed the Jetsystem actually doing anything either. Was yours abit like this or did it actually spray the water onto the laundry like the first Jetsystems?
