Please be careful, with that top chamber clogged, the steam in the boiler has no where to go an could explode! I would at least try to get some sort of screen, or even a stainless scrubby at the inlet of the top chamber to keep it from clogging and allow vapor to pass through unimpeded.Testing extraction from pellets. This is 5 oz of 6.9% AA Jester hops. Not getting too much. Probably has something to do with how well the steam can saturate and escape the biomass. There's not good way to "stir them up". Might be better to just boil them in the boil flask, might try that after a while.
