I have a Home Touch steamer, model PS-200. It will run fine for about 5 minutes and then just stop. I have cleaned it out very well with white vinegar and that doesn't appear to to any good. Looking through the hole where the hose attaches and through the fill hole there isn't any visible scale or mineral deposit. I really needed this steamer for my curtains before the Thanksgiving family comes. Please help. Thanks in advance, Lee Mosher
