Aqua Hot issue

[LaMonte Monnell]

My Aqua Hot has a red led light on circulation pump # 1. Does this have anything to do with the hot water for showers, or is this for the heat exchanger heat?

Lamonte,
Pump 1 feeds zones 1 & 5. I'm not sure what is serviced by those zones. My guess is that z1 is for heating the salon and kitchen and 5 may be for the water bay. You may need to simply try the shower and see if you get hot water. Sometimes you can get the pump running by tapping on it.

The output from the pump goes up to a brass check valve which also sticks sometimes.  Give that a tap or two as well.
