I think Lippert is the point of contact for warranty on the Hydraulics pump, so Heartland may point you to your dealer or to Lippert if you prefer to manage the repair yourself.
For your awareness, when we had a warranty issue with our pump, the dealer tech thought the pump needed to be replaced to fix a leak. Lippert agreed to replace it, but warned that they bench test the pump on return and would charge for the new pump if there was no trouble found or if a simple repair would have corrected the problem. Our dealer tech looked a little harder and found the source of the leak and was able to fix it without replacing the pump.
So Vinny, if the breaker was tripped and the batteries were depleted, and you get a replacement pump anyway on the possibility that there's a motor defect, you could find yourself in a sticky situation with a $1200 part. If Lippert has the same policy today, it might be a good idea to have a case opened at Lippert and see how things unfold.
