    I kept adding water until I put in a pot and it finally started brewing. But it is leaking from the bottom.

You don't. It stays in there inside the heating tank. When you put in cold water, it pushes out the already-hot water. Every year or so, you need to clean it out, or have someone do it for you. I just cleaned about a half inch of gunk out of one we have had at the fire station for about 10 years. Never knew we were supposed to clean it out...yuk. Tastes better now. Clean as a whistle! Also had to replace an overheat safety switch, $8.00 on-line.

    We have the same problem here with the safety switch. I tried to search for it on line but could not find it. Where did you find yours?

    How did you clean it? Did you remove the back cover? Of course it says "no user servicable parts" but that is probably to support their service centers. Please let me know. Thank you

I believe this maker works of the simple act of water in and water out. Reservoir holds about 2 pots worth of water to stay warm. Once water is poured in the hot water will be pushed out. You need to make sure the reservoir is full, once full initial warm up is around 5 minutes or so, thermostat will cycle the element to its set temp. Fill your pot - pour - put empty pot under fast or you will make a mess very fast because it doesn't take long for the water to pour out.. good luck

Okay, question. It does take quite a bit of water to get it ging. But, when you are all finished using it how do you get the extra water out of it?

Posted on Nov 05, 2008

Stupid question, but did you pour enough water in? It took a LOT of water before it finally started brewing.

Posted on Apr 26, 2008

I have one also. I just traced it down to a bad thermostat control. I have yet to figure out how to replace the thermostat. The problem is the thermostat stops heating the water before the water gets hot enough to be ejected over the coffee grounds.

Making coffee. Lost my manual.

Step 1
Warm your cafeti?re using some hot tap water and let it sit for a minute before emptying it out. Add two dessertspoons or a level scoop of Bewley's fresh ground coffee per person
Step 2
Pour in water just off the boil (equivalent to one mug per person) and stir to release all those fabulous flavours. Leave for 3-5 minutes to brew.
Step 3
Slowly plunge your coffee by pushing down on the centre shaft until the metal filter gently reaches the bottom of your cafeti?re.
Step 4
Pour your coffee then add milk and/or sugar to taste.
Step 5
Sit back, sip and enjoy!

I put water in and nothing comes out

Follow the three steps:
1. Check if the coffee machine is connected to the power socket and is getting power.
2. Pour the water in the correct place in the machine.
3. Make sure you switch the machine on when you pour in the water.
All these places like the position of the power button and location to put the water will be marked in the User Manual. Please refer it.

If it still doesn't work you may want to call customer support as specified in the manual.

I think my bunn-o-matic VPR needs cleaning and I do not have a manual for this machine. Can you advise on how to do this?

To clean the vpr you will need to take the lid off the machine. Be sure to unplug while doing this. First clean the water tray. You can unscrew the nut holding this tray and clean the tray in your sink. Put the tray back in and put the lid back on. Plug coffee maker in. Fill one coffee pot with vinegar and pour it in machine. After the water finishes coming out let the coffee maker sit overnight. Before you start filling the maker with water at least 6 times, be sure to clean the spray head. Make sure the 5 or 6 holes are free and clear of any build up. Then start with fresh water. Fill the coffee pot with fresh clean water and pour into machine. Let it finish and do this at least 6 times. If you can still taste or smell the vinegar repeat until you cant.

The tank inside holds about 2 and a hlalf pots of water. Once the tank is full, whatever you pour in will come out. The unit has to be plugged in to make coffee. Leave a pot under the brew funnel and pour a pot of water in. If nothing comes out within a minute, pour another pot of water in. Still if nothing comes out do it again. This time for sure water will come out. It will take avout 10 minutes to get hot enough the first time it is full to make coffee. If you have a thermometer, the water should be about 190 degrees F to make coffee correctly.

The machine is always on, so it is never full the first time you use it on monday. Try this before you use it on monday pour in a full pot of water in the brewer and put an empty pot under the head. Wait about 7 minutes, the machine will fill the tank and then be ready for brewing coffee.

I live in a limestone area and the flow through my Senseo coffee maker is slowly reducing. How should I descale it?

Believe it or not, vinegar is a blessing for cleaning nearly anything out of your coffee maker.

Fill your water reservoir 1/4th full with vinegar, then fill it the rest of the way up with water.

Run the coffee maker, then let it sit for about 10 minutes. Pour the mixture back in to the reservoir and run it again. Let it sit another 10 minutes.

Dump the mixture and use plain water this time. Let it sit for another 10 minutes. Dump the water, then repeat with clean plain water.

Wash the filter basket and pot with hot soapy water. If the vinegar smell is still present, just run it again with plain clean water.

Bunn VPS Series Commercial coffee maker won't brew

Hello. I would like to suggest that you pour in water, with a container under the funnel, until water does come out, it sounds like the water has just evaporated too far, and it requires more than a pot to bring it to the top. In the future, if you do not use it for a day or more, you need to unplug it, or just pour a pot of water in to keep it at level, as this unit heats all the time it is plugged in, and can actually evaporate all the water away, blow the element, damage the thermostat, or worse permanently damage the unit.

here you can find the user manual:

Hope that helps, and thank you.

Water overflows from filter basket

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.
