Also, make sure you're using the right grind; if the grind is too fine, it will clog the filter very easily and interfere with liquid passing through. Do you grind your own beans?
Ours would do that, the filter would fold over, grounds in the coffee. The wife had picked up new filters, they were short, only went half way up the basket. Turns out the old filters were to tall and would bunch up. Now it works fine.
My pa in law had that problem. Turned out the height of the filter basket was off a bit - too high. I removed the spring loaded 'pour while brewing' valve which wasn't fully opening. That fixed it, but he had to wait until brewing ended to pour a cup.
Had one of them permanent filters, when cleaning it I found the metal had separated from the plastic in one area. Couldn't see it just by looking, just happened to push on the spot and there it was.
indeed, I know what a perculator is, and yeah the tecnical term for a Mr Coffee is a drip coffee maker, but it works the same way as a perculator. The water is heated to a boiling temp in the coils in the bottom, which through thermal convection travels up to the spout where the grinds are. The difference between perculator/ drip coffee maker being one shares the water reservoir with the pot itself and the other has seperate reservoir and pot.
I said peculating because the Bunn is also a drip coffee maker but works entirely different using pre heated water, and almost a toilet flush system for the drip to start
Coffe maker now not overflowing, cant find old post
After 2 years being busy and annoyed at Mr Coffee maker for overspilling grounds into coffee carafe, tried to mess w/ spring, and a few other things, seems after 3 tests in a row that the blue Maxwell House 100% Columbian medium, works perfect!! WTH????? Tried other red Folgers Black silk, and some other Folgers types didn't, well finally the mystery is solved, hopefully!!!!
