Bunn 10 Cup Home Coffee Brewer Questions & Answers
How do you drain water from reservoir
I would unplug it . Wait till it cools, take the top off and push a small tube down inside the water tank but long enough to come out and get below the bottom of the tank and syfon it out.
Can I dump water out of reservoir and refill
To empty the reservoir, you need to turn the whole unit upside down while holding it over a sink or outside on the ground that can get wet. Be sure to turn it on and wait for the water to heat up before brewing a pot of coffee.
Very loud when heating
It's the sound of the water expanding quickly as it's nearing its boiling point amplified by the enclosed water tank inside. Normal.
Bunn Home coffee pot
If you remove the top , then remove the water basin, you will see the heater. At each end of the heater (inside a white tube) is a thermal fuse. Will read like any other fuse with a meter. They carry them at radio shack as well as other places. The temperature is on the side of the fuse. Needs to be replaced with the temperature.

Why does coffee come out while pouring in water its a bunn 10 cup coffee maker
The Bunn has a little stopper that closes the water drain port in the reservoir while the lid is open. You can see a little white plastic pin protruding up out of the grate with the lid open. When you close the lid, it pushes on that pin which causes the stopper to lift off the drain port, allowing the water in the reservoir to enter the heating tank.
If water is entering the coffee basket BEFORE the lid is closed, then something is wrong with that little stopper. It may have a chunk of debris on it preventing it from sealing, or it may be deteriorated, torn, disconnected, etc.
Only way to know is to remove the the screws in the grate and pull the top off exposing the reservoir, and the stopper assembly. The little plastic flapper disc should be seated in the reservoir drain port. It should be relatively flat (not wrinkled) and covering the drain port completely. Test it by pouring some water into the reservoir. If it drains out without you activating the stopper, then a repair is needed.
Move the lever up and down and check its operation. The arm must move freely and close when released. There should be no dirt or debris on the sealing surface of the flapper nor on the sealing surface of the drain port. Gently clean with vinegar as necessary. If the seal is damaged, then a replacement is required.
How do I stop water leak
If you're talking about the model shown in your picture, the leak is most likely between the water reservoir and the tank. Bunn uses a soft silicone seal for that connection that gets compressed over time and starts to leak water whenever you make a pot of coffee.
It's planned obsolescence. Bunn won't sell you a new seal. So you have to improvise. But it's simple enough to do.
Remove the top cover and the plastic water reservoir right below it. Don't tamper with the little valve that opens when you close the lid.
Look for the seal. It could be stuck to the bottom of the reservoir, or sitting loosely on top of the metal tank. Make sure to preserve its top-to-bottom orientation (don't put it back in upside down).
Apply a narrow bead of clear silicone into the grooved side of the seal. Press the seal gently onto the reservoir, then apply a thin layer to the smooth side.
Re-install the reservoir and reassemble the unit.
Why dos the maker only put part of the water when making coffee
Hi Rose,
My mother-in-law had a similar problem and I found that a transparent film coated the entire inside of the reservoir (you can see if yours does too by feeling the inside of the tank as deep as you can reach). Once I got it clean, it began making full cups of coffee again just like it did when it was new.
Here's how I got it working for her. Her tank has a fine meshed stainless steel screen over a "small valve" on the bottom of the tank secured with 3 small phillips screws. I removed the screws and took out the valve. The screen "looks" clear - but the same transparent film on the tank walls was coating the screen, too. As a result water flow thru it is significantly reduced - so it takes longer for water to pass thru it - resulting in "short" cups of coffee. The screen must be cleaned or replaced. I opted to clean it with an old tooth brush and soapy water. I then flushed the soap and the film from it while holding it under a stream of water from the faucet. I looked at the volume of water passing thru the screen to be sure it was cleared well. When happy with the flow, I resecured the valve to tank (after washing the tank in the top rack of the dishwasher as per the instructions on the underside of the tank lid).
The film is a type of growth - like algae. To help prevent regrowth or slow it down; do not let water sit in the tank all the time. Pour only enough water in the tank that you'll need for the next 8 to 12 hours - better yet - dump the remaining water out after each "batch" of coffee you need to make. Do not let water sit over night or for any longer than necessary. Be sure to WASH the TANK regularly in the top rack of the dishwasher - as per the directions.
I hope this helps & good luck!
!0 Cup home Bunn. Does not brew the number of cups of water coffee (water) in craft. 8 cups of water 6cups of coffee.
If you don't brew often enough you will loose a small amount of water in the tank due to evaporation while the tank heater comes on and goes off to maintain the proper brewing temperature, so if it has been a while since you last brewed, without coffee in brew basket put a carafe of water thru the brewer, you will get less than a full carafe out because it fills the evaporated space in the tank first then uses the rest to brew. Once your tank heater shuts off usually 5 minutes on less you will get out all the volume you put in.
Why did the coffee maker leak bad and now just quit wont gety hot
You seem to be saying the unit "leaked: really badly getting water all over; and now the hot plate will not heat up. Such "leaks" are usually caused when the basket is not pushed in correctly so that the water cutoff switch remains closed when it should be open. (The water cutoff valve is what allows you to remove the pot/carafe in order to pour a quick cup even while the coffee is still drip brewing.) If that cutoff vvalve remains closed for more than a minute or so, or less, water will overlow the basket because with its path out the bottom and into the pot is blocked' and it has not place else to go but over the top of the filter basket holder. Now, when such an overlfow (not leak) happens, there is the hot plate right below into which the overflow flows down. As long at it remains wet it will be short circuited and not heat up. So let stand and/or blow or hairdryer heat to remove all water (be sure to unplug coffee maker to to that). Now, once everything including the hot plate are dry, the coffee maker will either work fine, or will need to be replaced.
Why won't my bunn coffee maker turn on
You should check to insure that the tank inside the machine is full of water. Pour in 1 pot of water at a time until you get water to come out of the brew basket. If you haven't done any internal damage it should be ready to brew a pot of coffee inabout 20 minutes.
