Help resetting Pentair Ultratemp Heat Pump after "low water flow" alarm

[calvin2376]

My house lost power very briefly but for some reason it caused my pool pump to shut off (low voltage code). I flipped the breaker and that fixed the pool pump issue (seemed to reset itself) and the pool pump is now running fine. However, my Pentair Ultratemp heat pump still has the red service light on with the "low water flow alarm" on the screen. The heater has been working fine prior to this power outage so I suspect all that is going on is that when the pool pump stopped working, the heat pump sensed low water flow (understandably) and threw a code. Now though I don't know how to get the heat pump to reset itself and recheck the water flow (which should now be fine since the pool pump is running).

Long way of asking, does anyone know if there's a way to "reset" a Pentair Ultratemp heat pump or clear a code so that it rechecks things and sees they're working again? I've already tried flipping the breaker off then on, and the "On/Off" button on the heat pump screen does nothing.

When was the last time you cleaned your filter?

Your pool may have picked up enough debris in the storm to clog your filter.

I suggest you clean your filter. The UltraTemp should reset when it sees the minimum water flow.

Please create your signature with details of your pool and equipment so we know what type of pump and filter we are discussing.

The filter was cleaned days before the storm and we have a lanai so virtually no debris from the storm, and we have a weekly pool cleaning service, so I don't think it has to do with the filter. Is there anything else that could cause it not to recognize the water flow has started again?

Nope, unless the pressure switch has failed.

Clean the filter.
