My Pentair MasterTemp 300 heater recently stopped working.
here are the symptoms:
What I've tried:
I figured I'd consult the forum and maybe call Pentair before replacing anything else since things begin to get more expensive quickly!
i think it is odd that when I press "pool" is auto switches to Spa....And then the fact that I still get E-01 after replacing the thermistor with a new one...
Does anyone have any ideas on what may be happening?
thank you!!
here are the symptoms:
- When I press Pool, it automatically switches to SPA (we do not own a spa!)
- The heater will start and run for maybe 30 seconds then stop with error code E-01
- Service heater light is on
- I've also seen where I turn it on and I hear a click (solenoid?) and then goes straight to E-01
What I've tried:
- Researched E-01, found a thermistor replacement and installed
- inspected the internals of the heater (nothing seems chewed on!)
- removed top to view back of control board
- i see LED7 and LED11 lit ....not sure what they indicate
