I purchased a Lotus Bay in September of 2008. My display leaked and stopped working and it was replaced (my delear also said this is a common problem). Then the underwater switches disolved and they have been replaced. Both my filter cartridges have cracked and I have spent $140 to replace both of them. Now the ozinator has died and I am waiting for that to be replaced. The only three cushions that are glued to the hot tub are disolving and I am paying to replace those. Everytime I drain the hot tub and refill it the fountain will not work unless I detach the hose from the pump and reattach it (my dealer also said this is a common problem). My dealer, who has replaced and is replacing the broken parts under warrenty, was quick to remind me that my warrenty will expire on September 19th. I did considerable research and spent over $12,000 on the tub. I am also wondering if it is a lemmon.
I am using the strips recommended by the dealer and according to them the water chemistry is fine. The dealer does not seem to be able to explain how to use the spa guard chemicals with the ozinator and the vision cartridge that is in my hot tub. All I am doing is following the spa guard direction and tips I pick up on the internet
All that being said the dealer has been helpful, polite, and responsive to fixing the problems but with ALL the problems that have occured within the first 10 months of ownership I am extremly worried about this pattern continueing after the warrenty expires.
I feel your pain and have many of the same concerns. While I love the tub I did not expect all these problems for the $$ I spent
