It’s a constant battle with my Gaggia too. I don’t use the filling point on the top of my machine, I pull the water tank out and put about 2 days worth in, then rinse it out and repeat every other day. Even then, the inside of the water tank starts to feel a bit greasy after a few weeks and leave it any longer and I start to get globs of algae forming.
Regular cleaning is all you can do, but you can’t stop it completely. I always wanted to plumb my machine into the mains, but it’s the algae buildup that has put me off.
Now I've solved the grinder issue (for now at least), this morning I noticed algae/mildew in the water tank of my coffee machine.
Spent fucking ages with Milton steriliser tablets, descaler, and puly caff cleaning it. Must have run about 12L of water through it over the course of the day.
Read about it a bit online and looks like people recommend making sure the sun never reaches it, which is a bit difficult for me. Might cover it with a tea towel or something equally weird.
I do clean it regularly but it's hard to clean the water tank properly because it's not removable. Going to have sterilising the water tank part of my cleaning regime I think.
