    Pentair MasterTemp 400 Error code E05

    The heater will kick on for 30 seconds and then shut off - I replaced the stack flue sensor with pentair part #420002 - 0024S and the error still exist - the temp reads 80 and I hold it down and it doesn't change ...can't find any reason why this is not staying on and heating. could it be a bad...
