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.

If Bunn unit has been stored for a while, how do i clean it and get it ready to use?


Hi, W/D here.
To get your Bunn working again, place a filter into the basket, fill the reservoir, and allow it to begin dispensing into the carafe. This will take several pots of water to get it filled and overflowing (dispensing). Plug it in, and let the reservoir heat up. It's not necessary at this point to have the heating plate turned on, but you can do so if desired to check that it is working, then turn it back off. Once you hear the reservoir heating up, pour in 8 ounces of white vinegar, and let the machine dispense into the carafe. Place an additional 8 ounces of white vinegar into the carafe, and pour back into the reservoir. Let the water heat up again, and let the vinegar solution sit in the reservoir for about 30 minutes. Top off the carafe with cool water and allow the carafe to cool with the warming plate turned off. After the 30 minutes, pour the contents of the carafe back into the reservoir, and it will dispense again. The water in the reservoir will heat up again. Check the coffee filter for residue. If you see a lot of grainy material, change the filter, and repeat the cycle until the filter comes out clean. Save your old filters as you go. Lay them out in order on paper towels, and you'll be able to mark your progress. When the filters clear up, discontinue recycling the vinegar solution and, instead, fill the reservoir with fresh water. The sediment has by now been freed up (de-scaled) and will continue to come off in smaller and smaller quantities. Each time you place fresh water in the machine, the dispensed liquid will smell less and less like vinegar. When no vinegar odor can be detected, you are finished.
Best regards, --W/D--

No pot or instructions, how much water do you put in the coffee pot?Need a replacement pot for vp17 series. thank you


You should be able to pick up a replacement/new pot at your nearest Restaurant Supply store. Make sure you get a 64 oz./ 1/2 gallon pot.
Before plugging in your brewer, unscrew the sprayhead located just above where the filter basket sits and replace the basket, pour 3 pots of cold water through the opening on the top if the brewer is empty. This brewer has a reservoir that holds about 2 1/2 pots of water at brewing temperature when heated. Make sure you put an empty pot under the filter basket after pouring in the water. Water will flow from the brew basket when the reservoir has reached its capacity. Once water flows you can then plug in and energize your brewer and replace the sprayhead. It will take about 15 to 20 minutes for the brewer to reach brew temp, you will hear the heating stop. Put an empty filter and a dose of coffee (I recommend starting with a heaping measuring cup of drip ground coffee) into the filter basket, lightly shake it level, replace the basket and pour through 1 full pot of COLD water in the top. For best results pour the brewed coffee into a pre-heated thermal server if you plan on holding the coffee for more than 10 minutes or so.
Enjoy!

It only makes 1/2 pot when I pour the water in after sitting over night some times it takes 2 pot of water or more to make a full pot


I recommend slowly pouring in about a half a pot of cold water without coffee in the filter basket 5 or so minutes before you brew in the morning. There are 2 good reasons to do this-
1. Overnight you are having some evaporation due to the fact that your Bunn brewer has a reservoir that keeps a couple of pots worth of water at brewing temperature... a better temp than most "home" model brewers. This will top off the reservoir and you will not "short pot" except for the amount that the grounds themselves hold back.
2. Also overnight, due to the fact that the water is kept hot, the oxygen can dissipate from the water in the tank. Topping off with fresh water will mean a fresher first pot.
The Bunn brewers have a low wattage/keep warm heater so the actual heating element isn't doing all of the work over those long periods... it only kicks on when the temperature in the reservoir drops considerably (like after brewing). Be sure to let the brewer heat back up before brewing (you will hear it stop heating)
Hope this helps.

Bunn VPR Series Coffee Maker will NOT dispense the water into the coffee pot?


This machine has a reservoir that holds about 2.5 pots and keeps them at brewing temperature. Therefore you should pour in 3 pots (with a pot in place under the filter basket) until water flows from the basket. Then, and ONLY then, it is safe to plug in the brewer. If you plug in the brewer BEFORE filling the reservoir you will burn up the heating element and will have to have it replaced.
After the initial filling and heat up (about 20 minutes) you are ready to pour through a pot of COLD water through and brew.

How do i clean my cuisinart grind and brew coffee maker? i can't find my instruction booklet and it needs to be cleaned. thanks!


From the manual I found online here.
CLEANING AND MAINTENANCE COMPLETELY CLEAN AND DRY ALL PARTS AFTER EVERY USE. Always turn coffeemaker OFF and remove the plug from the electrical outlet before cleaning. Open the reservoir lid*. Remove the grinder basket lid by using the recessed area on each side of the lid. Then remove Grinder Basket. Open Filter Basket Door. Remove Filter Basket Cover, Filter Basket and Filter Basket holder. The grinder basket, grinder basket lid, filter basket and filter basket cover can be washed in warm soapy water and rinsed thoroughly, or cleaned in the upper rack of the dishwasher. Dry all parts after every use. Do not put any water in the unit once the grinder basket has been removed. Wipe the area under the grinder basket with a damp cloth. If water gets into the grinder motor, the motor may become damaged and may malfunction.
DECALCIFICATION Decalcification refers to removing the calcium deposits which form over time on the metal parts of the coffeemaker. For best performance from your coffeemaker, decalcify the base unit from time to time. The frequency depends upon the hardness of your tap water and how often you use the coffeemaker. To clean, fill the water reservoir to capacity with a mixture of 1/3 white vinegar and 2/3 water. Turn the coffeemaker on by pressing the ON button. One cycle should be sufficient to adequately clean the coffeemaker. When the cycle is completed and the five beeps sound, turn coffeemaker off. Repeat operation, this time using fresh cold water.

Have the Cuisinart DCC-1200 coffee maker. When you begin to brew coffee it brews some of it but leaves the whole filter top full with coffee and coffee grounds. Called then customer service line and...


It sounds like you were using the gold permanent coffee filter in addition to a paper filter. You should use one or the other.

The gold permanent filter must be cleaned between each brewing cycle.

Try this:

1. Remove the filter basket from the coffee machine.

2. Remove the gold permanent coffee filter from the basket.

3. Clean the basket thoroughly. Ensure there are no grounds clogging any holes.

4. Insert a new paper filter only into the basket. Do not use the gold permanent filter for this test.

5. Fill the water reservoir with the desired amount of water.

6. Add the desired amout of coffee grounds into the paper coffee filter.

7. Replace the filter basket into its holder in the coffee machine, and close the water reservoir lid. Press firmly on top where it says, "Press to Close".

8. Ensure the glass carafe is placed correctly in its position on the heating plate.

9. Turn the Function Knob to "BREW", then flip the Power Swich to "ON"

Hope that helps.

I think I've figured my yard sale EX 80 out. First, the way I think it works... in the tightly sealed boiler the water is heated to boiling, it must have a pressure release valve that sends the water/steam through the coffee and into the carafe. So dangerously hot and under pressure. Before opening the big round cap at the top (reservoir) relieve pressure at the steam tube valve (right side)

Here's how I made my first batch:

When opening reservoir always turn unit off, let reservoir cool a little between batches or you may get a cloud of steam in your face when pouring in water, might not be good for the heating element to shock it with sudden drastic temperature changes either.

Cleaned by running a couple of jugs of water through, cold water (4 on the supplied jug) into the reservoir all parts installed. I read somewhere online (not specific to any machine) not lukewarm water, if it's online it must be true... right?

Put coffee into filter basket/basket holder, matching amount of water in reservoir, 2 or 4 (markings on filter and jug). Espresso coffee should be very finely ground

Install all covers and the coffee basket/filter basket, close steam tube valve, install carafe and turn on the machine. Should get blast of espresso after a couple of minutes.

The steam tube (operated by the valve) seems a little cheesy on first try but I'll get better with practice. There's no steam to the tube until the reservoir starts to send steam to the coffee, the coffee kinda restricts the steam enough to send it to the tube. I was thrown a little because I didn't get steam when I was cleaning the thing, but I think that was because there was no coffee to block the flow. So I opened the valve at the start of the brew, steamed the milk, closed the valve and then the steam blasts through the coffee, tasted good.

Great $1 find.

Hope this helps.
