Question about Bunn NHB Coffee Maker

4 Answers

Grounds overflowing When brewing a pot of coffee, the grounds in the filter come up and over the top of the basket, getting into the coffee in the carafe. I thought making a smaller pot of coffee, using less grounds would help, but it still does it. What's causing this? It did not use to do this.

    I do not use a metal basket, but normal paper filters I purchased at the grocery store. I have just ordered the Bunn brand of filters in hopes that will solve this problem. I read that they are taller than those sold at the stores. It almost seems the water fills up the filter with the ground coffee faster than it drains into the carafe; therefore, spilling over and under the filter and through the hole into the carafe.

    I have the same problem. The filter basket fills faster than the coffee runs out. It makes a huge mess! Coffee and grounds all over! I like to grind the coffee myself. I tried pre ground coffee. I tried using less coffee. I also use Dunkin Donuts brand and I like to make it how they suggest. I'm guessing that I'm using the wrong filters. They say they will work for Bunn. I paid alot of money for this coffee pot. Not to mention the coffee is almost nine dollars a pound, my time and the roll of paper towels it takes to clean the mess. Any suggestions would be wonderful!! Thank you in advance.

    I too have this same problem, as well as my sister & our mother. (three seperate Bunn Coffee Makers) We all are baffled on what to do. My sister has only had hers for around two months & her problem is a great deal worse than mine. She had a huge HS graduation party over the week-end & as she was rushing around to attend to her many guests after preparing the coffee, the filter overflowed with coffee & grounds EVERYWHERE. Last week she followed the directions on cleaning the pot, using the wire tool, using vinegar, unscrewing the round knob the coffee flows from & using a toothpick to be sure all the tiny holes were cleaned. I sure hope the Bunn company reads these comments. What is the problem? Help! We all have had other Bunn makers over the years & none of us have ever had this problem. Is it just the newer models?

    I received a Bunn coffemaker and there was no booklet with it--the box had been damaged so I thought I could just fill it with water and put in a filter with coffeegrounds and turn it on. The water got hot but no coffee came out--what else can I do?

Having owned Bunns for years, we know (and still have) that they used to sell the units with a second, plastic decanter. You got your coffee even faster! I assume to save money, they did away with that 2nd decanter and you must use the same glass one. They added that plunger under the lid to hold back the water until you get the glass in place. (For 30 years, we never had this overflow problem). I used and ice cream stick between the lid hinge to hold the plunger down permanently. Stopped the problem. As in the old days, the water starts flowing instantly as you add water in the top.

If you don't have a second decanter, I would try breaking off a toothpick in the holes of the flow restirctor (located under the top where the basket goes). I would plug one hole at a time until I got the flow synced with the basket capacity.

I have solved it by raising the lid when two cups are in the pot until five cups are in the pot. Then close the lid. The real solution is to use the Bunn Brand filters if they are the same as the ones that came with the pot. I cannot find them at local stores. The filters that came with the pot seam to be an inbetween size.

When we put water in to brew a pot of coffee the water overflows in the basket and runs over. Why does it do this when the proper amount of water is added?


I assume this is a drip coffeemaker using a drip filter. If so, does it grind the grounds or do you add them? Are you using a paper filter or the gold one? Try a coarser grind and make half a pot. Then check level of brewed grounds. Never use a gold and paper filter together.

Need a manual for JWX27


You can find the manual for this coffeemaker directly at the following link (for as long as it lasts): http://demandware.edgesuite.net/aamb_prd/on/demandware.static/Sites-mr-coffee-Site/Sites-mr-coffee-Library/default/v1414150683537/documents/instruction-manuals/JWX27_43_56431310.PDF

With this coffeemaker, you can brew with the cover open. I recommend observing a brew cycle to see if the coffee with floating grounds are overflowing the filter into the strainer basket. If this is the case, inspect the strainer basket's valve to make sure it is not blocked and working properly. Also make sure the pot is fully in place so that the lid aligns properly with the strainer basket to open the valve adequately. Otherwise, the filter and/or the coffee grounds are too fine. I recommend a permanent filter basket (around $5) and course-ground coffee. Both will add to better tasting coffee.

Keeps spilling over during brewing


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.

My cuisinart grind and brew model dgb-700bc shuts off right before it is done brewing and i am getting coffee grounds in my coffee pot


Too much grounds or not running through fast enough. Right filters? basket flow hole vlesr? Sounds like it's backing up and flooding causing the grounds to get by yje filter. If you dare, **** the hole out just a tad. with the end of a sharp knife. not too much. You can always take out mor. This is called consuner calibration. Good Luck -Ned-

Bunn coffee pot blows water out top of basket


Check the grind on the coffee, brew a pot without coffee and if it overflows, then the machine has a problem. If it doesn't then try a coarser grind on the coffee.

Sometimes coffee maker overflows


Do you grind your beans at home before brewing or is it ground from the store. If you grind just before brewing check her grind and compare it with yours.
Also check to see if she levels the coffee in the basket. Usually when a pot overflows it is because of the grind or the way the coffee sits in the basket.

Coffee Machine Brewing Water


Try an experiment - brew a test cup, but use only a small amount of grounds in the brew basket (use a paper filter) [or else, put the grounds in the gold tone filter basket]. See if the machine makes coffee (albeit weak coffee). If it does not make coffee, see if the water is draining properly from the brew basket, or if it is leaking over the sides of the brew basket. Also, make sure the lid to the brew basket is completely open and in the correct position.

If you still get water only in the caraffe, replace the brew basket. The part costs about $11.95 with shipping - or even call Cuisinart to see if your 3-year warranty will cover the issue.

Can I adjust the water flow for finely ground coffee?


You probably have coffee ground for a drip coffee pot, not an automatic drip coffee maker. With a drip coffee pot, you put the coffee in and add the hot water on top of that. You might want to try a coffee press. They are fantastic for the finer grinds of coffee. Some Mexican coffees are ground almost as fine as flour and a press works great. You can get a press for about $12 & up.
