When the heat pump is on, this message shows "low water return" on the screen.  How can I correct this problem.
Thanks.

Thank you for writing to me. Most of the time that means the heater is not getting enough water flow. It could be a dirty or worn out filter, bad water pump or the propeller of the pump could be clogged with debris. Dirty pump filter basket, valves in the wrong position causing restricted water flow. Bad valves that failed in the closed position. (Even though it looks like they are open) It may also be a bad or miss adjusted water pressure switch on the heater of a sensor too.
Hope this helps,
 
Sincerely
