Hot water wont circulate completely around my baseboard. The pipes are only hot for about 20 to 30 feet past the Area Control Valves.

    Air bound, check valve stuck, new install?

    I bled the lines at the beginning of the season when I got a check valve error and the fan kicks on once every min for about 30 seconds.

    Are you talking about the FAN in the WM boiler or another FAN in an air handler or something?


    The Combustion FAN in the WM boiler operating for only "30 seconds" sounds like a call for heat is interrupted before the system gets to ignite and complete the start up cycle.


    More details are necessary to understand the actual issue.

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

    Show the boiler and system piping. 
    How many zones?
    Indirect water heater?

    That is the worst sounding blower I've heard in awhile. 

    Sounds like it's doing a prepurge, then trying to light burner....failing...then doing post purge. 

    Does it light? Is there gas to the appliance?
