I also was experiencing the same issue. We did not have the maintenance kit either. So, because I was not getting ANY action from the spout, I took the machine to the garage and blew, and blew and blew my compressor blower nozzle into the needle jet. After several attempts, HOT water started squirting out. My was definitely clogged behind the norm I'm suspecting, guess I'll just descale it again at this point. But to have some flow again and the compressor is encouraging.
