        I like clean. I not am proposing a "less clean" alternative. I am trying to see if I can get the machine and the pump to pull the cleaning solution into the machine via the water inlet line and then allow it to go throughout the whole broiler system that way. If anything it could possible be cleaner. I just don't know how water moves through the broiler. It seems to have two sides? I don't know which is why I am asking if this is a feasible option.

        Message 3 of 8 , Nov 29, 2011
          Howdy Ed,
          Here's why I developed the approach I recommend. If you pull a citric acid solution into the boiler and HX using the inlet hose, it is diluted by the water already in there. You could drain the HX & boiler before you begin, but then you're back to removing fittings.

          So I figured it's simpler to loosen 2 compression nuts to descale the HX & 1 valve to descale the boiler. But it's possible to do it the way you describe too - in fact that's how most machine techs do it. I'm just not convinced it's the most effective use of my time.

            If you descale by using a bucket of citric acid, it's easy enough:
            1) When you use the shot buttons the water flows through the refill solenoid and through the group.
            2) When you use the hot water lever or knob (depending on model of ES-1A) the water flows through the refill solenoid to the boiler.

            I would use a heavy concentration of aciduated water - maybe 1 cup for a half-gallon of cold water. I don't know how much you'd pass through the two paths to get them free of scale?

            Let us know how it goes for you.

                The anti-vacuum valve is the one with the small tip that pops up when the boiler reaches ~205F. I use it to pour the slurry into because it's the easiest to remove. Before you reinstall the valve, anneal the copper washer by holding it over an open flame until it's cherry red. This softens it so you'll get a good seal.

                To pour a slurry into the HX, remove the tube that goes from the volumetric valve to the HX (both nuts). You'll need a drinking straw or a turkey baster with a small tube to empty out the HX.

                Keep us posted.
