My Bunn coffeemaker has started overflowing at the funnel

We recently moved to Indiana from Colorado. Our new house in Indiana has a water softener and I have read that soft water can cause Bunns to overflow. I have not read anything about how this is solved. I have pulled the nozzle and it was not clogged. Is it just a matter of getting a different nozzle? If so, what nozzle do I go with? Thanks.

It's possible that the soft water is helping the coffee "bloom" (and eventually overflow past the top of the basket) more than when you were using harder/more mineralized water. All else held equal, there's a few things to try to solve the concern, as one or a combination of the following may work.

Try:

...reducing the amount of water you place in the tank, and expect smaller/less servings.
...putting in less coffee in the basket, balancing the risk of getting "watered-down" coffee (see #1 above).
...using/buying coarse ground coffee instead of the fine powder (for the reasons below)

Now if you grind the beans yourself, also try:

...using a burr grinder (instead of a blade-type) for more consistent coffee size, as the fines from using a blade grinder may be clogging your mesh/paper filter (not the nozzle!)
...grinding the coffee a little bit coarser to give more space for the water to run through.

Hope this helps.

There are several reasons why the coffee maker is leaking water from the bottom. It could be clogged by mineral deposits because the coffee maker is overdue for descaling. Another possibility is that the valve pump is broken, clogged, or damaged.

Make a solution of one part vinegar to two parts distilled water. Vinegar is acidic and can easily break down calcium deposits. ...
