That's not too bad. As mentioned, a dose of hot water and citric acid should do the trick. With the cap off, heat the tank to boiling and turn it off. Do not lift the lever to run through the group head. Allow to sit 1 to 2 hours. Unplug. With mitts, pour out citric acid solution and inspect. You might need to repeat.
Mix the citric acid and hot water in a measuring cup. Use about 1 tbls for the La Pavoni.
