Unit heats up but when trigger button is held down, no steam is released from nozzle. Steam pressure is built up in unit, when unscrewing the safety cap steam pressure is noticeable. Concentrator nozzle is not clogged, I cleaned all nozzles with a paper clip. Can I add a teaspoon of vinegar to water, to aid cleaning?
I solved the problem, the metal (hot!) release rod gets stuck & needs a little push.
Unfasten the top by prying off the rubber gasket after removing the top. Remove the 2 small phillips screws, then remove the front that holds the nozzle, & remove those 2 phillips screws.
Carefully pry up the top with a putty knife, inside you will see the tip of a metal piston that the plastic release knob is supposed to contact. Set it on its front, & soak the piston with a light household or sewing oil, giving it a few taps with a blunt object occassionaly to loosen, heat up & test before reassembling, but remember, the piston is very hot. When you push on the piston with a screwdriver, it should release the steam, but also stop when you let go. Work with it a little & it will come back to life.

Steam comes out of the wand even when the trigger is not depressed, so the Polti never comes up to full pressure due to the steam escaping through the wand. I've replaced the hose and trigger unit but that's made no difference.
CLEAN WATER AUTOMATICLE COMES OUT WITHOUT SPRAING THE TRIGGER
