Tunze power head not working right

[PI Guy]

I’ve got an older tunze powerhead that is setting off the alarm on the, not sure what it’s called, blue box that connects it to the power source. I’ve cleaned it but still setting off alarm and not working to full potential. Any advice?

@rvitko any thoughts?

Your best bet is to find eletronic repair shop and get it repair there, it should not cost much
-if only problem is a power supply, usually is, you could connect it to any 12v power unit like one made for laptop etc, but you need to find a way to connect it on controller then, on newer pumps this is much easier
