My La Cimbali M21jr sat for about a year and a half and now I only get steam out of water dispenser. Group head works and steam wand works after running descale solution thru unit. Pulled tap from machine and now all I get is steam. Could there be blockage at tank or valve assembly. I am hoping to not have to do total teardown so any advice would be great.

My first guess would be underfilled boiler. If the water level were deep enough to flow out through the pipe, it would be boiling water, not steam, flowing. Is the boiler-fill circuit working properly? I know there's no sight glass on those, but you could remove, inspect and clean the fill-probe, look into the hole or dip in a chopstick to try to determine depth.
