OVER FLOW My Bunn seems to pump the water to fast for the filter to handle it. I have the same coffee maker at work and don't have a problem. I am using the same coffee and filters both places.

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.

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

Depending on which maker and how old it is it may have a switch for the heating element. The BUNN brewers have a reservoir inside that needs to be topped off BEFORE energizing the heating element/plugging it in. This usually will require about 3 pots being poured through until water starts to flow from the filter basket. (Have a pot in place to catch the water) Then it is safe to plug in your machine. After it heats up (about 20 minutes) you can load your grounds and pour through a pot of COLD water and voila... coffee.
Also, due to the reservoir you will want to not shut off or unplug your brewer... then it will be ready to brew next time.

Tressia,
An overflow can occur when using certain brands of coffee that are finer ground or using a water softener, bottled water, reverse osmosis, or filtered water. If you will call Bunn Customer Service, you can get a flow restrictor sprayhead which will eliminate this issue.

These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

Are you using a finer ground coffee? Or do you have a water softener, use filtered water or bottled water? If so, please call customer service to get a flow restrictor sprayhead which will eliminate this issue.

Sometimes this happens if you use filters that are too thick for the brewer. If you are using Bunn filters andthis keeps happening , up above your filter basket, there is a sprayhead. Turn that off, and look at it to see if it is plugged up.If there is no sprayhead, then that could cause your filter basket to overflow, as too much water will be coming into the basket too fast.

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.

You may be grinding the coffee to fine making the draining a little slower. There's something called a fast flow filter that may help also. Also, make sure that you aren't jamming the filter down to partially block the drain hole ensuring that it is freely draining out unobstructed

remove the little rubber stop on filter basket but you now have to wait for coffee to finish before takeing coffee
