Pentair Minimax NT Problems?
I am having problems with my Pentair Minimax NT. After sitting idle for several months I decided to fire up the heater. It will heat up for about 30 minutes, then just shut off. It tries to heat up again but just shuts off. After several cycles, the service light goes on and it shows a E05 or E04 code.
This happened about 2 years ago and the service guy replaced the DDTC, ignition module, gas burner etc. It worked fine for one season now this.
