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.

I have a bunn cwtf twin,I put new ready lights on both side work for about a week and the they wont light up. and the side the the faucet only brews warm coffee. but the other side does find. HELP

The green ready lights do not last that long. We never replace them on units we service. They are cheaply made. Each side of this coffee maker has its own thermostat. Check to make sure the thermostat is on all the way. If it is check the voltage on the warm side. Make sure it is in the 208v area. This warm problem is 85% the thermostat not set right and or needs replacing.

Replace heating element in bunn CWTF15-APS

You should call your vendor for service. Especially if this equip is on loan from them.
*** the following is for information only. All service should be done by a qualified tech.***
* CWTF have an on/off heater switch in the back of the brewer plate. Make sure this is on as it provides power to both heater and heater blanket.
* There is a schematic on the back, side, or top panel. You will need a continuity meter to check the following:
* There is a thermo fuse in series with the heater element. check and replace if open.
* There may be a 2nd High limit fuse (disk shape) or another thermo fuse on the top of the tank. usually zip tied to the water faucet lines. check and replace if open.
* There is a thermostat (adjustable) in series with the element that may be open, shorted, or out of adjustment/calibration. Replace as needed.
* The element could be open or shorted to ground (ripped casing exposed electrical wires to water and grounding to tank housing). Replace element (and gaskets while your at it)
* I suggest getting a repair kit with all the gaskets as they are probably burnt or cracked from age.

Just installed a Bunn cwtf15-3 Brewer. The water in the tank does not heat. Rear switch is on and the ON/LOWER switch is turned on and water does fill the tank. Coffee container will fill when the start...

Remove the front panel and make sure the pressure stat is turned up to max and back it up 1/4 way. If you have done that already then remove the top and check the thermostat and the inline fuse.

What size breaker do I need to install a CWTF - Twin 4/2? I have 208 volts available. Wattage is 6850.

A 50 amp breaker would be best. To find proper amperage its Watts divided by volts, then multiplied by 1.25 for draw.
