My spa is an Coleman Horizon 400.Just replaced the ozonator with the new Balboa 52468.After replacing this the lcd on the spa control pad has dimmed to where it is barely readable.The ozonator powers up and the lamp illuminates during the proper filter cycle times but the ozone is not being pulled into the spa. There are no bubbles and no smell . Please help

This is a dual voltage ozonator. Did you wire it for the correct voltage? Did you install the new checkvalve that came with it and is it installed correctly? Do you have flow through the ozonator jets?

Yes it is installed for 240 and the new check valve is also installed properly.I can blow through to the spa and clear the line, as well as suck through like a straw to insure that the water will not backup to the ozonator and all seems fine.It turns on and illuminates during the filter cycle but nothing appears to be pulled through to the spa.Any ideas why the lcd is very dim almost appears to be unlit? Thanx
