Utica UB95M-200 E02 issues

in THE MAIN WALL
I've got a 15 yr old gas boiler. A week after replacing a noisy circulator, we had an extremely windy night and I woke with an E29 error. I powered it off and could never see that error again and could not get the boiler working. We replaced the control board, then had the E29 error so we replaced the blower. Now I get an ignition error (E02) at least once a day (but usually not on a warm day). Plumber thinks the PVC pipes need to be disconnected from the burner and blower assembly and flushed. I'm open to other opinions while I wait for a gasket part. Shop vac without disconnecting? Control board parameters?

    So, I'm guessing this is the first time with this problem after 15 years of operation? Condensing boilers require regular maintenance. It is quite possible that there is a blockage in the vent or in the condensate trap. if the trap or drain pipe is blocked, eventually the water will build up and block the airway for the exhaust vent.

    When was the most recent maintenance completed?

    Customer "It was just serviced"
    What kind of service?
    Customer "they replaced the circulator"
    That is not maintenance... That is a repair service call. Again... When was the most recent Maintenance completed?
    Customer. "They need maintenance? I can't remember the last time."

    After you make that expensive repair and you still have the same problem, What will you check next?

    Guilty. Lack of maintenance and guidance on maintenance from installer. What is your recommended annual maintenance on this unit?

    The service manual tells what should be done for maintenance.

    You can choose to do what you want, but you cannot choose the consequences.

    Annual maintenance on ALL condensing boilers. The manual as Bob @Ironman suggests, has all the info you need. If you are a DIY type you can get the stuff you need and do it yourself, or you can get it done by a pro. Just remember to do it correctly, it won't be cheep. You can't get an hour or more of labor for a $39.00 special sales coupon in the local shopping flyer. The more invasive procedures may not need to be annual but at least once every 3 years. But it is safe to say that Maintenance will make the equipment last longer.

    An aluminum block boiler is much less forgiving when it comes to proper maintenance.
