Basically removed the reservoir and cleaned out all the calcium, deposits, adjusted the thermostat to a less hot setting, replaced all the gaskets and it's a 100% win. New unit like ours would run $500-$600 dollars easy. Repaired this one on less than $40.00. Super satisfied.
Also, my grateful thanks to your company for the EXCELLENT SERVICE and the correct parts. You folks are super.
Many Thanks!!
