PoltiVTT2085 1998

Question

the water get hot but since 2 days back the steam does not release out the flex hose when connected. Never gave any problems since 1998 so this is a really fine machine and I would like to fix it. I have a automotive business www.winbrake.com so am technically minded but need to have the working principle befor I tackle the repair as I can't find any Vaporetta repair agents in South Africa Johannesburg
