Bunn coffee brewer brews too slow?

lime builds up on the metal surfaces where the hot water cools down or evaporates, such as the sprayhead, the waterline to the sprayhead, the reservoir inlet, or the insides of the tank. the sprayhead and reservoir inlet buildup will restrict flow and extend brew time and may even not brew through all of the grounds. to fix:
1. remove the top of the brewer. the reservoir is right on top and the drain looks like a nut with a hole in it. lime will plug this up. using a deliming spring or even a philipshead screwdriver, push through and twist to get rid of the lime.
2. unscrew and remove the sprayhead and bore the lime out of the holes with a small flathead screwdriver or a paperclip.
3. if necessary, unscrew the reservoir drain nut, place it and the sprayhead in a cup of straight vinegar. for more stubborn lime, use CLR, but wash and rinse thoroughly.
4. if you have a deliming spring, push it through the outlet waterline to the sprayhead all the way past the 2 elbows and pull in and out, removing any lime buildup.
5. rinse parts, reassemble the reservoir, and brew a little without the sprayhead first to get rid of any loose lime. then put sprayhead on and run a test brew. if it brews short or too much, see tip for recallibrating

The water is coming out of our BUNN very slowly.What is the matter?

Your sprayhead and steel tube which connects to the sprayhead from the tank may have a lime build up. Simply remove the sprayhead and clean it with a wire brush and make sure the holes are clear of any lime or debris. In order to clean the tube which is what the sprayhead screws onto you will need a deliming spring.

Coffee brewing comes out in a fast steady stream when brewing, coffee doesn't brew properly and comes out weak. taste like unbrewed.

If it comes out in a steady "stream" it sounds like the sprayhead is missing. The sprayhead disperses the water out and evenly over the grounds.
If the sprayhead IS in place then it could be a temperature problem. If the temperature is not hot enough the coffee will not brew correctly.

Had about a week. if i fill with 50 ounces of

Try taking the filter out, and turn the sprayhead off the unit. Put the basket back on, and try pouring clear water through the unit. If the water runs through fine, you either have a plugged sprayhead or are using too finely ground coffee. Look at the holes in the sprayhead, and make sure that none of the holes are plugged. If the basket still overflows, try using a drill bit to make the hole in the funnel a little larger. Good luck.

When we make a pot of coffee, the water goes through to quickly and the coffee looks like weak tea, how can we fix this, we only got the coffee maker about a month ago

This is usually caused by a missing sprayhead above your filter basket. take out the filter basket, and see if there is a sprayhead up there, or if there is just a little round pipe that the prayhead screws on to. If it is missing, you can contact your local Bunn dealer, or phone bunn directly, and they will take care of you. You can get a list of repair centers in your area at

Unable to remove our sprayhead from our Bunn NHB Coffeemaker

You might try putting a butter knife underneath the sprayhead to remove it. If this doesn't work, then please contact customer service and request a tool that can be provided to remove the sprayhead.

Coffee grounds leaking out of the basket

When you are grinding your own beans or use certain types of coffee, you need to use a flow restrictor sprayhead. If you will contact customer service, a flow restrictor sprayhead can be sent out to you at no charge and this will eliminate the problem you are having.

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

My Bunn coffee maker is leaking water

Does it leak all of the time or just when you pour it in. There are a couple of solutions. There is a tank inside and a pan that leads the water to the tank. There is a gasket between the basin pan and the tank. It could be leaking from there but that is pretty rare. Generally what happens is that the basin may get chips or scale that builds up around the basin to tank access nut. The nut secures the basin to the tank with a flat,round silicone gasket between them to keep water from leaking. If scale impeads the free flow of water from the basin to the tank the water backs up and will give the impression of a brewer leak. I haven't worked on one in awhile but there are two screws that hold the pour over top to the brewer. The top can carefully be removed and a visual inspection is done (remember to unplug the brewer) to see if the access nut is clear. The lime could be in the nut or just below and inside the 3/8' hole that leads the water to the tank. Bunn makes a delimer spring that is used to clean out the sprayhead that I use to clean that nut. Speaking of sprayhead, if the leak happens during brewing and seems to come from the front take the brewbasket away and run about a half a pot of water through the brewer and see if it comes through the sprayhead's 5 holes. If it dribbles and doesn't fan out into the pot, or tracks along the roof of the brewer and drops down the side or back clean the sprayhead and try again. Also if it is the A10 or B8 I would run your delimer spring through it. If you don't have the spring you can get one at your local Bunnomatic representative's office. Or call Bunnomatic in Springfield, Illinois and they can send you one and instructions of how to use it. The picture of the bunn I am sending you is of a restaurant model but uses a pan just like the smaller bunns. This one is stainless but the principle is the same. The nut right by the 1/4" spicot is the water access nut, just like on yours. They will clog and leak, but I would check your sprayhead and the free flow of water from it before I do anything else. If it isn't either one of the solutions I have spoke about it could be a tank gasket or worse. Rick in Indy91db15f.jpg
