Hi guys, I am a new member and i have a major heat problem with our freedom xt 3000. After initial pre-heating time i get high temp from my solution hose, but after a few minutes heat is gone. If i let unit run for ten minutes the heat is back but only for a few minutes again. Unit is not dumping water to waste tank, i descaled machine and heat exchangers, bled hxs', changed thermostat, Unit has been down now for 10 days and i need help with this problem. Any ideas
