    Perhaps you should've stated that an extension bar is also required

    The 3 way solenoid doesn't affect the water flow through the group head, which was the OPs problem.

    It really does, if the valve is not energized, you won't see any water out of the group head.

    About stuck bolts, today I had to deal with really corroded one and decided to make some pictures for this thread.

    If you have really stuck bolts my advice is to follow this procedure.

    1. Carefully cut the head with your angle grinder
    2. Remove upper boiler
    3. Apply heat with your torch
    4. Apply penetrating oil
    5. Undo the bolt with your pliers, surprisingly stuck bolt will come out easy

    Not always that easy if the machine has spent any time in London

    Heating up to the red the bolt is the key to success. This machine was extremely scaled, you can count it from London
