You should call your vendor for service on any commercial brewer. (Especially if it's on loan from them)
*** the following is for information only as all repairs should be performed by a qualified tech.***
* There is an on/off heater switch located in the back of the brewer. This should be on when the brewer is needed. There will be a 20 minute wait for the "ready" to brew light comes on. If you brew before the light comes on then the coffee will be only warm.
* If everything is on and looks okay but it takes forever to light the ready light then the main heater is not working. Call your vendor for service.

P.S. The 3 liter brewer has a much larger tank than the regular 2.5 brewer. So expect it to take a bit longer to reheat a full brew. Some customers will request the 'Airpot' or 'Pump pot' to be filled to the top which means even more water is needed to be heated. Expect at least a 20-30 minute wait on reheating. I've found that customers that use this large a pump pot will brew +3 pots in a row. (Regular, Decafe, and a 2nd regular or 'flavored' coffee.) Often brewing without waiting for the ready light. If this is the case then mention this to your vendor. You may need a 2nd brewer, larger brewer, or have the brewer hooked up to the 'Hot' water line to get pre-heated water to the brewer (though they may need to modify the water valve to one that is rated for hot water inlet line.). If your using larger 3L decanters then having pre-heated decanters and using the 'pour over' function can aid with faster brews. Though this method is a lot of work for the operator.

SOURCE: Our Bunn VPR coffeemaker takes a LONG time to heat

We left vinegar in the coffeemaker overnight. Seems to have done the trick - water is heating up now after 20 or so minutes instead of several hours.

SOURCE: when i make coffee sometimes the water that comes

Once a Bunn has been plugged in and the heater has warmed up, about 8 mins on new models, 10 to 15 mins on older models, there is NO delay needed between brew cycles. The VPR can produce 8.5 gallons of coffee per hour. You can easily make 4 to 5 pots back to back with no significant brewing temperature loss. Matter of fact I just finished making my 5th awhile ago.

Remember, no1bigredd, that Before you plug in your pot the water tank must be full, or you run the risk of damaging your heater coils and/or thermostat. The proceedure is outlined in your owners manual. If you have lost your manual, here is a quick refresher course for you.

1. With the coffee pot unplugged, fill your resevoir/tank until water begins pouring out of your sprayhead and brew basket.
2. Wait for the water to finish dripping then plug in your Bunn.
3. Let your Bunn warm up for at least 8 minutes.
4. Run a test cycle with clean water, remembering to use the water pitcher provided for this purpose, while leaving your empty pot on the burner beneath the brew basket.
5. If your cycle completed, and your coffee pot is filled to the desired level you are ready to make coffee.

Remember that these Bunn models have no water filter installed, so, the cleaner the water the better tasting the coffee.

If, however, your temperature is still too low during your brew cycle, you can remove your top cover and adjust your temperature setting on the thermostat directly below the hot plate.

If your temperature still remains too low to properly brew you will probably need a new heater coil. Even a heavily scaled heater coil will heat your water properly, but this same scale can also crack and abrade your coil as well as your thermostat bulb.

You also have a heat switch located on the top of your heater tank, which is designed to open the circuit if your heater coil becomes too hot. This little button can corrode and lose connection over time, and should be cleaned if you see signs of rust, decay or green dust on the contacts.

Our Bunn VRP SERIES MAKES NOISE WHEN WATER IN THE TANK SITS AWILE


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)

My Bunn model CWTF35-TS heats properly sometimes and is only luke warm other times! Just wondering what maybe causing this?


Defective temperature sensor is my guess, try running white vinegar through it a few times, the sensor may have hard water deposits on it which can alter the readings.

Make sure the 'vacation' switch is turned on. In addition to the warmer switch on the front of the unit, there should be another switch located on the side/rear of the coffee maker. If that is turned off, the water won't be pre-heated, and you end up with luke-warm water going through the coffee during the brew cycle. If that is not the problem, then there is an issue with the tank heating element and the unit will have to be repaired.
