Welcome to our forum.
Quick update...still not working...I've tried everything suggested, both by peeps on here and by a local ex-D1 dealer. They said it may be a faulty flow switch since it did work briefly for a day or so. The error did clear for about 30 seconds yesterday, enough time for the tub to start heating again, but then it came back .So, is it easy to swap out the flow switch? I'm guessing you need to drain the tub?On a sort-of-related note, why are things so much more expensive here in the UK?!? For example, a new ozone assembly would be $255 in the US, but is ~$843 (£509) in the UK!!! Am I right that they are slightly different (to take different electrics into account)? If not it would be much cheaper to buy from the US, even with postage and import taxes.I'm beginning to think this will be an expensive restoration to bring it back to its former amorous glory; there are other issues that I discovered last night, will post more when I'm at home.Thanks all,Ian
