We had our 34J Windsport in the shop 2x for Water Heater Issues. Would not work on Electric side, wound up being wire nuts for unit not being tight, come to find out, wire was in a bind the 2nd time and came undone again. Hopefully fixed this time.
Fortunatly, There was a small leak in Water Heater 1st go round, so they had to replace all base cabinets due to water damage.
The 1st year is a Big headache with a new unit, but we still love it...
