Wasn't there some talk about WM Ultra series 2 having an issue with 02 error code and locking out? Just got a call about one and will see it Monday...

    I had that Friday Tim,,

    In my case it was caused by a few drops of water(and I DO mean drops!), from my hose connection draining the exp. tank. Read my "first Ultra experience" thread.



    I had to tear the top of the boiler open, remove the MCBA, open its cover,,,, then use a blow-dryer. Luckily after about an hour I was successful,,,



    Good Luck!  :-)
