Water flow has slowed down.

if the coffee is ground too fine, it'll take longer to brew through. either grind more coarse or call bunn for a flow restrictor (800) 352-BUNN (2866)

I purchased a special flow restrictor sprayhead from BunnAtHome.com because I use decaf coffee. Also if you use a finer grind then you need this to slow the water so it doesn't overflow.

delime the sprayhead and the reservoir drain in the top with a deliming spring or a screwdriver

Here is the SOLUTION(S):
1. Buy a sprayhead that restricts the flow2. Let the water flow through for a few minutes, then lift the lid while it flows through.3. Don't use Decaf4. Plug up a couple holes on your current spray head

Some people also try adding fresh grounds to brewed grounds, resulting in an overflow. A restricter valve can be used, but a better solution is to simply pour in half the water at a time. This is what people who buy non Bunn filters do to stop overfills.

Tammy,

Plug the coffee maker in and fiIl with water again and let it flow through. Do this several times.

I don't think household bleach would cause any damage to the unit. Industrial bleach, yes, but not household, especially if diluted with water.

Let me know what you find.

You could have scale building up on the heating element and thermostat probe. try running a 1/3 white vinigar - 2/3 water mix into the brewer, let it heat up completely, then run several pots of clear water through the unit. keep pouring water through it until the vinigar smell is out of the water,

The Bunn needs Bunn filters because they are thinner and let water through faster. The cheaper filters will overflow. Bunn's claim to fame is fast...this is just part of the fast process.

Use the de-liming spring to clean the copper tube behind the spray head. Pour several pots of clear white vinegar through the unit to further remove lime and scale from the interior of your coffee maker. My Bunn is 24 years old, and the only replacement parts I've ever required are new carafes and the 4041 silicone washer repair kit.
