Ok just got in last night. I was in Canada for the past 11 days 2 hours from any cell service, electric or indoor plumbing (yikes) Anyway Fred had it figured out in about 15 minutes. I knew it was going to take a cleaner who was a gear head to figure this out and as I thought it was very simple. I will not go into too much detail because 2 very highly regarded service companies looked at this problem and could not advise me on what to do or fix it. The problem was that the machine would not prime. What it came down to was the machine has a water box and a water tank, you can use either. We always pull from the water tank. Fred shut the valve off to the tank, opened the valve to the water box filled it and primed it from there then opened the valve to the water tank at the same time to get a good prime going then shut off the water box. Done.
Mike D. told me how to do this a few weeks ago ( priming from the water box) but when I tried it, it did work but kept losing the prime after a day or so. I guess priming it with the big tank while the box valve is open is the key to getting the prime to hold.
