Frequently Asked Questions - CWTF15-1 Bunn
How do I descale the Bunn CWTF15-1?
To descale, fill the tank with a mixture of white vinegar and water (1:1) and run a brew cycle without coffee. Repeat with fresh water to rinse. Do this every 3 months or when mineral buildup is visible.
What type of coffee filters should I use?
Use standard Bunn commercial paper filters (flat bottom, 8-12 cup size). Alternatively, use a permanent gold-tone filter, but ensure it fits the funnel.
Why is my coffee maker not brewing?
Check that the water tank is full and the funnel is properly seated. Ensure the brew switch is turned on. If still not brewing, the internal thermostat may need resetting; refer to the manual.
How do I clean the spray head?
Remove the spray head (unscrew or lift off) and soak in a vinegar solution. Use a toothpick to clear any clogged holes. Rinse thoroughly before reattaching.
Can I use a timer with this coffee maker?
The Bunn CWTF15-1 is a manual pour-over model and does not have a built-in timer. You can use an external outlet timer, but ensure it is rated for 1500W.
What is the water-to-coffee ratio for best results?
For optimal flavor, use 1 level tablespoon of ground coffee per 6 oz cup (180 ml). For a full 15-cup pot, use about 15 tablespoons (3/4 cup) of coffee.
How do I replace the decanter?
The decanter is a standard Bunn glass carafe. To replace, simply lift the old one off the warmer and place the new one. Ensure it is seated firmly to avoid drips.
Why is my coffee weak or cold?
Weak coffee may indicate too little coffee grounds or water temperature too low. Cold coffee usually means the warmer is off or the decanter is not making proper contact. Check warmer dial and decanter placement.
Is the Bunn CWTF15-1 compatible with a water line?
No, this model is a pour-over unit without direct water line connection. It must be manually filled with water for each brew cycle.
How do I adjust the warmer temperature?
The warmer has an adjustable thermostat. Turn the dial under the warmer plate: clockwise increases temperature, counterclockwise decreases. Test with a thermometer if needed.
