Review on Durgol Swiss Espresso Descaler and Decalcifier - 4.2 fl. oz (Pack of 2) for All Espresso Machines and Coffee Makers - Compatible with All Brands by Eric Dailey

I read the directions several times because they didn't seem quite right. They tell you to add a 4.2-ounce bottle of descaler to the same amount of water and start the machine. My machine will not work with only 8.4 ounces in the water tank. I used 2 bottles which was barely enough and did the best I could. I have to run several gallons of clean water through my car and the water still tasted bad. To make matters worse, my machine is no longer developing enough pressure to function properly. I need to take it to the only shop certified to service my Italian car in the US. The drive will take about two hours, the repairs will probably cost a fortune and I will be without my car for a few weeks.
