Sorry Mike, I meant with no items in ie jewelry etc., just fluid. Normally there would be items in the cleaner with the water and, not being technical, I was just wondering whether that would make a difference. No, I always go way past the minimum level. I'm getting more convinced of it being a problem with the lecithin. The last machine a tried was a bona fide professional cleaner with a 60 minute timer and 2 year guarantee. That was broken in little over 15 minutes of continuous use and the tank temperature was below 30 degrees when it was designed to go up to 80 degrees (Centigrade).
All the best Richard
