20 Most Recent Bunn CWTF 15-APS Coffee Maker Questions & Answers


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. Aloha, ukeboy57

by 'reset' do you mean that you moved it, tilted it, shut it off and back on?

1. you need a 64 ounce graduated measuring cup or bucket 2. make sure the brewer is heated up to temp and the green light on the front is lit 3. open the front panel of the brewer 4. put the microswitch on the circuit board to "unlock" position 5. make sure the sprayhead is cleaned and open, the brew basket is on, and the measuring cup is in place to catch the water 6. press and hold the brew switch until the inlet solenoid clicks 3 times, then release 7. once the water level is at about 40 ounces, turn the main red switch off and let the rest of the water come out 8. if it brews short, press and hold the brew switch again until the 3 clicks, then press and release the brew switch for 2 more second of brew time (up to 5 times per brew) 9. if it brews too much, press and release the brew switch for two less seconds of brew time (up to 5 times), then press and hold the brew switch until the 3 clicks then release 10. once you get to 64 ounces, put the switch on the circuit board to lock and replace the panel 11. enjoy!

Tip

if it's actually boiling, replace the high temp limit fuse on the top of the tank on the inside rear of the brewer. may be stuck shut. if it's just overflowing the container, recallibrate by using a 64 ounce measuring cup and the instruction on the inside of the front panel

open up the top and check the trough drain for lime. if it is obstructed, the water will overflow. use a screwdriver and poke it through the drain

thermal fuse is blown. it is located in the top, right rear of the machine in what is now browned tubing. you can either bypass the fuse with a jumper, or get a new part through bunn (800) 352-BUNN (2866)

check the heat switch in the rear. if it's on, check the thermal fuse in the top right rear of the brewer. it'll be in a now browned tubing. you can get it through bunn (800) 352-BUNN (2866)

first, delime the sprayhead and the trough drain in the top with a flathead screwdriver to ensure maximum flow. next, you'll need a measuring cup or bucket that goes up to 64 ounces. then follow the instructions on the front panel

It's threaded. Simply unscrew it.

Yes it is possible to go the the next larger element.
Yes if the machine was plumbed there would be a difference in the way it brewed the water temp. if you look at the end hose in the pan from the solenoid, it takes a while for it to pour out 3liters.
Try using a different sprayhead(if yo;u are using a 6 hole try getting a 5 hole. That will constrain the flow of water a little more allowing the element more time the heat the water.

This is caused by one of three things - either your limit high limit thermostat is gone, your thermostat is sticky, or your element died. Try turning your thermostat up or down a little bit. if your thermostat is stuck, this will usually start it again. Look for any burnt wires as well, because sometimes they will burn off of a contact.

195*, it sounds like you have a bad thermal link or thermostat. The tank warmer blanket is all that is maintaining temp.

It is possible that the brew volume needs to be set, remove the front panel and you find the instructions to set the brew volume.
