* call vendor for service. Brew timer or water level float needs adjustment. * Make sure your using the correct brew pot for this machine. It's 64 oz decanter if I remember right. Some of the older glass pots are smaller. Especially if it's the roundy one that looks more like a ball. It should hold at least 1 quart of water easily. Ask your vendor for the correct pots (they don''t like you using 'other' brands of coffee if it's printed on the pot. * Long shot but possible the valve was put in backwards. Either way the vendor should replace it. Aloha! ukeboy57

* Most decanters are made of tempered glass and unless cracked it should not leak. * Make sure the two pots you are using (one to pour one to brew) is the same size. Check by filling one then pour into the other. If they don't match then get a matching one. * Most overflowing pots are caused by over filling brewing tank. This can be caused by re-pouring additional water into the brew tank. (automatic brewers may have a leaking water valve - call your vendor for service) * Partial brewing (taking coffee from a brewing pot) and then putting in more water. * Removing the pot BEFORE it stops dripping. It leaves a puddle of coffee on the warmer plate *Over filling the water tank. Most times the extra water will spill out the back. But some may overflow into the basket area then the warmer plate. * Follow the MFR brewing instructions for filling. * All brewers should stop water drips after brewing. If you get a constant drip AFTER brewing then have the brewer checked or replaced. Call your vendor. Aloha, ukeboy57 PS: I've noted that you don't mention the brand nor model of the server you got from Kohls so I'm guessing it might be a dispenser or even a bunn dispenser which is different from a decanter as it has a serving spout. You find these at banquet halls where it's dispensed from a small faucet. You can find similar faucets from bunn.com or most restaurant supply stores as it's a very common item. Amazon.com has them too. the part tat leaks is the rubber boot or worn spring. best to buy the whole faucet and keep the old one for parts as needed. amazon link: https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=coffee+dispenser+parts+faucet&rh=i%3Aaps%2Ck%3Acoffee+dispenser+parts+faucet

Humm, G-3 grinders. Okay what common problems I've come across: * Wrong setting for grind on label. Usually means worn out grinder burrs. But this does not happen often unless you are using it to grind commercial amounts of coffee? It's a retail level grinder meant to be user friendly and simple to use. Say grind a bag of beans once every 10 mins or so even with customers lined up to grind there own. Running a G-3 constantly is usually done by upcoming coffee vendors whom are using it for small flavored bean batches. But expect the burr plates to only last 3 to 6 months. We used to change it every month till the boss bought a bigger pro grinder. (whew!) * Out of calibration (for grind) This usually happens as soon as it's installed. Either the grinder got banged (Dropped?) around or the lock nut was not tighten down. If caught quickly then it's a simple adjustment. Left unchecked will wear out the burrs or crack the plate. * Trips out breaker. This is common at retail stores as it's located in a shelf rack that really does not have the required outlets. Many times there is a brewer(s) connected to the same line. It only trips out when one or both brewers are heating and the grinder is running a very fine grind. * Trips out breaker when grinding espresso or very fine grinds. Worn burrs or slim chance the grinder was miss calibrated (but you would catch this when first installed) * Shocks the customer. Dry climates or heavy air conditioning will build up static electricity at the chute. There usually a small chain attached to the chute to prevent this. Attach a SHORT metal chain or thin cable to the metal case of the grinder and add a metal clip to attach to the coffee bag. Many use a chain and clip just short enough to keep the bag positioned under the chute. Note many coffee bags come with bag clips. Just make sure the clip and chain can't get stuck in the grinder. * Not working. This is usually the on/off switch as it gets beat up the most. There is sometimes a safety micro switch under the chute to sense if there is a bag there. I've found may have been defeated. * No power, check cord, breaker (GFRI) outlet, Plug prongs if broken off or bent. * power but no motor hum. Tripped thermal breaker (usually a red button on side or back. Some models may have it inside on the motor itself. Call for service to check. * Turns on but loud hum (may be hot too). Burrs stuck. This could be from adjusting grinder while grinding beans and adjusting to a fine setting. Grinding finer slows down the beans feeding the burrs. Large settings flood the burrs with a lot of beans. Adjustments are usually done when the grinder hopper is completely empty. If loaded and turned down from coarse to fine grind the beans already in the burrs get crushed and stuck between the plates thus locking them in. It may be possible to clear the hopper and open up the grinder to its coarsest setting to jog out the crushed beans. Otherwise call for service to have the burrs cleared manually. *Finally check with your vendor if your still having problems. Aloha! ukeboy57

First, Though I have worked on many Bunn commercial systems. I'm not quite familiar with the newer MCU though I've worked on similar single cup home systems. * Most single up systems like the Cup/Pod/Capsule usually have a air flusher that pushes all the water out of the brewer to extract all the flavor and prevent old liquids left in unit. * If your still dripping, have wet pods/capsules/cups, then it sounds like the air pump is not turning on or not working properly. Bad pump could be a cracked or loose hose as the pumps don't really wear out as it's only air (hopefully clean air, no dust). Call for service. * The brew cycle might not be completing thus not continuing on to the next step which is to pump air in. Brew sensor or timer out. call for service * Computer is out or fried (especially after an electrical storm). Call for service. * Finally, most of these home units do not have serviceable parts. Most take at least an hour to service. So if your not in the warranty period it may not be worth fixing. But be sure to call your service provider or MFR for advice. Aloha! ukeboy57

It sounds like the T-Barbed fitting on top just before the brew head. There is a water by-pass system on large commercial brewers. The idea is that it's possible to over-extract the ground coffee if too much water is poured into the worn out ground. There are several types of systems and ideas on how to overcome this problem. over extraction is one of the causes of bitter coffee. You've tasted old peculated coffee from old brewers of the 1950-60's. * the t-barb fitting comes from the main brew head valve then tees off to the bypass port which can have another solenoid or just a pin valve. the pin valve is manually adjusted to flow anytime the brew head valve is turned on. water is partially diverted to by-pass the grounds and drips directly along the inside of the brew funnel. Open it too much and you get weak watery coffee. Too little then stronger bitter coffee. I suggest turning it all the way clockwise (off) then opening it 3-1/2 turns. Check and adjust to taste. * you should call your vendor for service and parts if needed. * Parts are available from Bunn vendors,, Amazon, or your local restaurant supply as Bunn is a very common brand. Curtis parts may fit too. The barb is a standard 3/8th T fitting if I remember right. You may also find it at a Refrigeration plumbing supply like COSCO plumbing (Not the COSTCO membership store) * It's just a divert-er so even a nylon t-fitting may work. * Final; you can find the parts and manuals from Bunn.com even some of the discontinued models.

VPS 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-messured packets for office use. A simple guide is one tablespoon per cup. (level or heaping spoon is up to you) * Since your brewer was bubbling at one point. I'm guessing it had water in the pre-heater at one time. But if it's not in use and left plugged in all that time then the water has probably boiled off. Hopefully someone unplugged the brewer prior to the unit blowing the thermal fuse. * You can test the VPR by following the Pre-fill instructions I've listed earlier. If the brewer heats up and does not continuously boil (shorted condition) then try a brew. If it works then your okay. Otherwise the unit will need service for a blown high limit or bad heater element. * Call your coffee vendor anyway. Many coffee vendors will service your brewer of even replace it as long as you buy coffee from them. Ask around. Aloha, ukeboy57

Bunn machine smells hot * Check for unusual sounds from brewer (other than sizzling from warmer plates). There should be a gradual boiling sound accompanied by some steaming at the top of brewer. This will turn off and ready light indicating the brewer is ready to brew. * You may sometimes hear a slight boiling sound from time to time (about 15-30 mins apart). Notify your vendor as the warmer blanket may be out. (your brewer will still work but call them anyway.) * Check your manual for setting up procedures and checks. It's available on line: http://www.bunn.com/product-manuals * Constant boiling (more than 15 mins) with lots of steaming is a sign of an electrical problem. Unplug machine and call vendor for service. * Final; Unplug unit and check for 'stuff' in pour over tray. I've found Chocolate, Cream, Milk, powder, sugar, honey, and a dead rat in the tray. Crew will repour old coffee or beverages into brewer to 're-heat' them. Notify vendor for cleaning or replacement (it happens all the time.) Aloha, ukeboy57

1.check the setting of your timer 2. open the top and see if the pan is overflowing or water is sprayed from the jet . rudy.ky

Hello, Trent - I checked the User Manual for the Bunn Speed Brew < http://www.bunn.com/sites/default/files/care-and-cleaning/49740.0001.pdf > and didn't find the problem you describe in the troubleshooting (Let's Solve) section. Therefore, I recommend you telephone Bunn Customer Service and talk with a someone there. See this web page to find the right number to call and the days and hours of availability: http://www.bunn.com/contact-us The company may need to send you a replacement machine.

It depends on the model you have but usually as long as you had water in the tank you can use as usual. If the power was off for a long time it will take up to 20 min to heat the water back up to temperature.

There are two heaters in a VRP unit (Pour over style) The brewer has a tank that your last office person poured in a full pot of water. The main heater senses the colder water and begins to reheat the water to near boiling. The new water pushes out the same amount of water into the brewing basket (funnel with coffee). Once the new water has come up to temperature then the main heater turns off. There is a warming blanket around the inside tank. This keeps the water hot and ready to brew. It uses less power than the main heater. If this blanket fails then the water will cool down to a point where the main heater heats everything back up. You may not notice this as the only indication is luke warm coffee on a freshly made pot or a 'boiling' noise every 15 - 25 mins. This VRP probably needs servicing (check Thermal blanket and Thermal fuse)

The heating coils may be calcified. With the machine off- pour some vinegar into the water tank. Let it sit over night. then pour clean water in and run it at least 3 times to flush out the vinegar.

You will need to replace it, parts are not made for repair except under warranty.

Ac supply may be Good but PCB may be foulty

you would have to unplug it, and then turn it upside down over a sink with the cover and coffee pot removed. be careful, the water in the reservoir is quite hot and ready to brew.
