Just noticed your posting as I was looking for information on the B85 myself. Your problem is the on/off switch, I had a similar problem but was able to take a switch from an old unit that I had; spares no longer seem to be available. I have finally decided to upgrade my shower so I will shortly be selling two spare (brand new) units that I purchased some time ago. Keep an eye on ebay and they will be listed shortly.
