Small baseboard heater no heat

I have a new install boiler weil mclain cga-4 with taco 007e pump on single loop 1” with 3/4” baseboards. The bathroom baseboard won’t heat up I have purged it several times at the baseboard plenty of pressure and no air coming out. I’m stumped I can provide pictures any help appreciated

    How is it piped? Monoflo loop?

    Are your other baseboards heating? If it is a series loop they will all heat or not heat. If it's a monoflo loop it's a different story

    I’m pretty sure it’s mono flow it has a 1” loop with 3/8” branches off of it all other baseboards work fine

    The classic air bubble, look for a pipe pitched the wrong way. Worse case you’ll need to cut in a purge

    It's definitely an air pocket. If you have a coin vent on the baseboard you can easily get the air out.
    I've heard a few drops of dawn dish detergent added to the boiler will help with air removal.

    The perimeter loop and Tee's were replaced?

    It wasn't just a boiler replacement? Sure, piping at the boiler was replaced but the branches were altered too?

    They didn't reverse flow did they?

    You might need to bleed that rad a lot longer than 2 minutes. It might take an hour. The long runs can be a real pain in the butt.

    The branches look original too me but there is some new copper piping where I believe they added the kitchen and bathroom ones the bathroom one is on the end of the loop I’ll try blending it longer

    Super, if the runout(s) or the bleeder is pitched incorrectly, you can bleed till you’re red in the face- ain’t gonna happen. Sometimes one can get lucky by man handling the upside down piping and get the bubble to move
