I cleaned my bunn coffee maker last night and now the heater and warming plate don't seem to work. Could I have knocked something loose?

replace the switch

You will need any multimeter to test this but it may not be a bad switch but rather a failed heater element. You can buy these on line very cheap or at Radio Shack and auto parts stores. Don't spend over $20 (I have several bought for <$5). The added features or claimed accuracy won't do a layman any good.

That is one of the best coffee makers ever.It will last for a long time.Yes it is ok to leave it unplugged.Do not ever leave an empty pot on a burner that is on.Once a month,put 1 cup of white vinegar where the water goes,and run the machine.This will clean the inside.After you use the vinegar,run one pot of clean water through the machine.

The manual for this coffee maker can be found at this link:

While the manual does not contain repair instructions, it does have some troubleshooting tips to follow if your coffee is not staying hot.

VPS/VPR are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.
BUT there is one main difference! The VPR and similar COMMERCIAL coffee machines are quick brewers. They usually have a pre-heated pot of water stored inside the machine.
* VPR's and similar machines REQUIRE a pre-fill and heating period prior to brewing. This means it's sitting on a level table and filled with water until water sprays from the brew head. At this point the unit is plugged in and the heater is turned on (CWTF's have a toggle switch behind the machine). Brewer will pre-heat the water (there may be some water discharge from brew head as the water expands). Ready light will come on in about 15 mins.
* To Brew; Place coffee grounds in filter, place in funnel and brew head, clean empty decanter under funnel, slowly pour one full decanter of water (cold or hot) into brew tray. Do not overflow tray. Allow water level to sink before adding more water. Only fill with one pot as an equal amount will come out the brew head and funnel.
* FYI Coffee grounds are usually in pre-measured packets for office use. A simple guide is one tablespoon per cup. (level or heaping spoon is up to you)
* Final; Getting back to unplugging when not in use. Yes there is a heater in the machine that keeps the tank warm. You can save power by turning off the warmer plates when not in use. Some units have up to 6 plates. The warmer "Blanket" is designed to keep the tank warm enough to brew and not waste heat or electricity. Yes unplug the unit at night if there is no night crew drinking coffee (or tea) But follow the Pre-heat instructions mentioned above prior to plugging the brewer back in. If the tank has been emptied at night or dried up after an idle week. Then there is a chance you may over heat and blow the thermal fuse. Or at best have a half pot short brew as the water dried up.
* Note leaving the brewer plugged in without brewing daily is not a good idea. The water evaporates and eventually drys out the pot. Takes about 1-2 weeks but it does blow the fuse(s) and the unit will need service.
* Final; Follow the Bunn set up and care instructions (manuals from Bunn.com for down loading. (*FREE*)

Hello

Coffee makers have a heating unit in them which draw a lot of current. If it is on the same circuit as refrigerator, toaster and other it will trip the breaker. Also, some breakers are more sensitive than others. Have an electrician run a separate circuit for the coffee maker outlet. Try running it in the dining room outlet, which I hope is separate from the kitchen outlets. Is the house old? Older homes have a lot of mixed up wiring.

Our Bunn VPR was delivering luke warm coffee. The problem was lime scale buildup on the heating element. I recommend using a cleaner such as Brew Rite or a vinegar solution. If it still does not heat properly, unplug and remove the heating element for cleaning. This corrected our problem.

You can get this part from Bunn. Click on tis link and look for your model or customer service. I hope this helps. http://bunn.com/retail/service/service_form.html

You can either replace the warming element with a new one, or some people put 3 or 4 pennies on the top of the warmer tray. Don't laugh- this really does work!

This would only applie to a newer modle. I can tell u this that if u contact the company by phone they will offer you a replacement at no charge to u.
