Not an expert of chrome clad machines but I am pretty good on moka after 5 decades. Here a few tips I may suggest:
1) the best coffe comes from the smaller bialettis, the big ones, more then 3 cups, do not the job well.
2) the water should be always below the valve
3) never press the coffee
4) the fire under the moka or the electric heat should be low, coffee has to get out slowly
5) let the coffee comes out with the lid on, the vapor on lid shouldn’t drop on the coffee
6) switch off the fire just few seconds before the coffee ends
7) clean the moka after every use without soap with a rugged sponge
😎 use oligominaral water
9) coffee should be ground for the moka that means not as fine as filters
I know that it sounds like handling turntables compared to cd player, but as TT the results are much more satisfying.😁
Sorry if you already know it, but I thought it might worth repeating.
