    Angry Pentair MasterTemp 250 Nat Gas - won't turn back on when needed

    Pentair MasterTemp 250 Nat. Gas

    Unit is 6 months old (old unit lasted 2 years, cupro-nickel failed)
    Had to replace igniter within 2 weeks of purchase
    Water-flow is 68 GPM
    No warranty option (direct replacement of old unit by self/not prof. installed)

    Hi all,
    This unit is used at a hotel and runs 24/7. It heats up to 85 just fine. When it comes time to turn back on, unit usually throws the service heater light. Unit will not come on until turned off and back on.

    Manual (lots of help there) says I need a new control board. I swapped out the control board from the old unit. Same scenario, sometimes it works and sometimes it doesn't.

    Thought maybe the diverter valve on the filter was drawing air since it was leaking. Just replaced that and no change.

    Thank you for any suggestions, as I am just muddled at this point.

    Welcome to TFP. Let's see if someone can help you sort this out.
    I'd bet you my bikini you'll never get TFP water from a pool store!
