Oh no, a mini flood sounds like a nightmare, especially messing with your morning brew! I had a similar ordeal when my dishwasher leaked and somehow got to my coffee maker. My coffees were just not the same after that. I found a great replacement filter for my Breville machine that totally fixed the issue. You might want to try this Claris water filter I found at Appliances Spares—it's compatible with Breville machines and worked like a charm for me. Here’s the link to the exact product I used:
