20 Most Recent Bunn 10 Cup Home Coffee Brewer - Page 6 Questions & Answers

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. Ensure you are using the correct grind for an automatic drip coffee maker, neither too fine nor too course. (See instruction manual.)
3. Do not overfill with water. Use the carafe to pour water into the reservoir. This is because a "cup" in coffee terms is defined as 6 oz, not 8 oz. Note: Some coffee makers define as little as 5 oz as a cup.
4. Make sure the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. Clean your machine with vinegar or as instructed by your user manual at least three times per year, more if your water supply is hard. A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew, to produce "off" tasting coffee, or to clog and overrun the filter basket as the water runs through the grinds.
9. Ensure that the coffee machine is sitting level on the counter.

You may need to add more grounds. We use 1/2 cup coffee grounds for our 10-cup machine, and it comes out perfect every time. If you prefer to grind your own beans, use 1/2 cup of beans, then grind.

Without the model number, it's only a guess but this failure is normally related to a protective device called a thermal fuse. If this has failed, the heater element may have to be replaced with it since they are often welded together as a unit.

For us, it is a faulty switch. This may be a warranty issue -- depending on how old your coffeemaker is. We had to send back the heating UNIT ONLY at our cost. The good news is that we got a COMPLETE replacement. Now we have an extra basket, glass server, etc

It sounds like you are either missing a sprayhead or need the flow restrictor sprayhead. If you will call customer service at 800-352-2866 we will be happy to resolve this issue for you.

With the machine turned on and hot, pour in 1 quart of white vinegar and close the lid. Let the vinegar sit for 2 hours. Then flush out the machine with 8-10 decanters of cold water.

How old is the machine? If you have cleaned it and delimed the machine and it still is dripping slow, the machine may need to be replaced. Please call service at 800-352-2866 with the model and date code.

There are many possible points that the leak can be.

You need to disassemble the machine and work it without the side panels of course with extra care since power electrical cables are exposed.

In this way with a very good visual check while the machine is in operation you can identify the leaking point and fix it.

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.

This machine is still under the warranty. If you call 800-352-2866 we can replace your machine free of charge.

Hi,
mix half white vinegar and water together...then pour this solution in just as you would if you were making coffe....minus the coffe grounds of course... then run it through a cycle and then run clear water through again... and you will be good to go...do this once a month or so to keep it working great...

We recommend cleaning your machine with white vinegar for 2 hours and then using the metal deliming tool under where the sprayhead is located. IThen flush it out with 8-10 decanters of water. If this doesn't fix your problem, please call customer service at 800-352-2866 with the model and date code.

If you will call Customer Service at 800-352-2866 with the model and date code we can further assist you.

Have you checked to make sure the sprayhead is on your sprayhead? If it isn't there, than please call us with your model and date code and we will replace it. The other reason for weak coffee is the thermostat not keeping the water at 200 degrees. If you have a meat or candy thermometer, please check the water temp as it comes out-it should be between 175-185. If it isn't, then we would need to replace the machine. Just call customer service at 800-352-2866 with your model and date code.

This can occur with the use of finer ground coffee or use of soft water, filtered water, or bottled water. If you will call 800-352-2866 with the model and date code, we can send you a flow restrictor sprayhead which will alleviate this problem.

mcdevito75 here, Try to clean your coffee maker by running a decanter full of white vinegar thru the system 2--3 times, then fesh water to rinse out the vinegar. Use a new or clean filter at the beginning of the vinegar treatment and after when you rinse with regular water.

If you will call 800-286-6070 we can help you with this.
