Why does my Bunn coffeemaker spill over the filters when I use Bunn Filters.

I purchased a special flow restrictor sprayhead from 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.

My Bunn velocity brew machine is always overflowing. What can I do? Thanks John.

This is several things it can be to cause the overflowing problem. Most the time is will be some of these.

  • Use BUNN paper filters.
  • Check to make sure the sprayhead is in place.
  • If you use decaffeinated, fine grind coffee or have soft water, you need a flow restrictor sprayhead.
Here is also a link with other trouble shooting areas to check and Phone number if needed to order parts directly from bunn.

Either the coffee grind is too fine, too much coffee or incorrect sprayhead. Count the amount of holes on the sprayhead.

Coffee grounds overflow

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.

My7 GRX Bunn coffeemake doesn't brew in 3 min-more like 12 and I don't believe the water spray is working although I am not sure.

It is becomming clogged. Start with the sprayhead. Check all of the holes, be sure water is running from all 5 holes. If the sprayhead is clear, check the water tube. Use your delimer spring. Don't shove it in. Twist in through as if it were a drill bit. If it starts to become resistant don't keep twisting, you may not be able to get it out because of a lime scale blockage. Not knowing where you live or the grain of the water you use, I can't say for sure. But if the spring goes in and you are left with about two inches of spring comming out of the sprayhead you may have cleaned what was blocking the water out of the way. Now run a pot of water without the sprayhead or brewbasket. Just put your pot underneath and pour water in with the Bunn pitcher. Is the water comming out in a good stream now. If so put the sprayhead back on. If the problem presist check to be sure that the nut that holds the spraytube in place. It is the nut right in front of the sprayhead. If it is there then you may want to get a new sprayhead. Rick in Indy
