I put in an Excel in Sept. 2010. First one was dead on arrival, the second worked fine until 2 weeks ago. Since then, I've had 2 more. The 3ed doesn't work at all, the present 4th, works 1 time in 4 and puts out warm water when it works.
They offered me my money back and said it is the boat.
What can I do to the boat to make it work? Any ideas?
The problem is in the valve in the lower/middle of the unit, when I operate the microswitch by hand, all is well.
