Have a propane Pentair Max e therm 400 and it’s giving me issues now. The heater will turn on and heat up for about 1 minute or 2 and then will shut down and the fenwal will flash once showing a air fault. I’ve replaced the water pressure switch, thermo regulator, hi limit, and thermistor. The air flow switch seems to function as it should but the button pad doesn’t fully work. Any ideas? Has a very strong water flow to it as well
New hot tub owner and need help. Thanks everyone!

Can you elaborate on the button pad that doesn't work?
You cant turn the heater on or off?
Or you cant adjust the temp?
All of the above?
Check the tubes or hoses that connect he air switch to the blower air horn and the gas valve. Also the wires that run all the way back to the board from the air switch
