Tip & How-To about Bunn CWTF 15-3 Coffee Maker

Bunn coffee brewer brews too slow?

Lime builds up on the metal surfaces where the hot water cools down or evaporates, such as the sprayhead, the waterline to the sprayhead, the reservoir inlet, or the insides of the tank. the sprayhead and reservoir inlet buildup will restrict flow and extend brew time and may even not brew through all of the grounds. to fix:
1. remove the top of the brewer. the reservoir is right on top and the drain looks like a nut with a hole in it. lime will plug this up. using a deliming spring or even a philipshead screwdriver, push through and twist to get rid of the lime.
2. unscrew and remove the sprayhead and bore the lime out of the holes with a small flathead screwdriver or a paperclip.
3. if necessary, unscrew the reservoir drain nut, place it and the sprayhead in a cup of straight vinegar. for more stubborn lime, use CLR, but wash and rinse thoroughly.
4. if you have a deliming spring, push it through the outlet waterline to the sprayhead all the way past the 2 elbows and pull in and out, removing any lime buildup.
5. rinse parts, reassemble the reservoir, and brew a little without the sprayhead first to get rid of any loose lime. then put sprayhead on and run a test brew. if it brews short or too much, see tip for recallibrating

SAYS COFFE READY PUSH LARGE CUP AND A COUPLE OF DROPS COME OUT THAN SAYS FILL AND PUSH STEAM HAVE DONE AND REDONE SEVERAL TIMES STILL NOT GETTING A CUP OF COFFEE TOOK TANK OUT AND CHECKED FOR FLOTATION IT IS THERE AND PUT TANK BACK CHECKED THE BEANS NOT STICKING PLEASE HELP THE 1800 IS NOT OPEN ON SUNDAY


Hello.

1 Perform the initial setup on the coffee maker. Make sure the coffee maker is not plugged in. Slide the empty funnel into the funnel guides, fill the decanter with cold water, open the lid and pour water from the decanter into the brewer, put the decanter back on the base, then close the lid and wait three minutes for the internal tank to partially fill. Open the lid, fill the decanter with cold water again, and once more pour the water directly into the brewer. Put the decanter back on the base and wait for water to flow out of the funnel and into the decanter. Once it has stopped flowing, pour out any water that is in the decanted and plug in the coffee maker. Press the on switch to turn the coffee maker on and heat up the water in the tank.

2 Ensure the lid is completely closed. If the lid is open, the Bunn coffee maker will not brew coffee.

3 Check the see how much water is in the water tank. The Bunn coffee maker will not begin brewing coffee if less than 20 ounces (4 cups) of water is present in the water reservoir tank.
4 Delime the coffee maker. Unplug the coffee brewer and allow it to cool down. Remove the sprayhead by turning it by hand and set it aside. Insert the flexible deliming tool into the sprayhead tube until all but two inches are showing. You may need to twist and force the tool to go in. Slide the tool in and out several times to loosen lime buildup.
Check the sprayhead for lime buildup. If there are flakes of minerals, they can be removed with a toothpick. Scrub the sprayhead with soap and water. Rinse the sprayhead with water and replace it in the coffee maker. Pour water into the water tank and turn the coffee maker on, allowing water to run through without making any coffee. This will flush any lime fragments through the system. Empty the decanter

Thanks.

Before calling service technician, open following link for Rheem tankless resources including error codes and possible manual.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Read your manual for troubleshooting, advisories and required maintenance.
Tankless are maintenance heavy.
1L means tankless heat exchanger has lime build-up.
De-lime tankless unit.
U-tube has videos for de-liming tankless, but there is more to consider:

De-liming is yearly maintenance requirement.
Tankless are prone to lime build-up
Regular de-liming will not restore full efficiency to tankless unit.
Tankless cannot be exposed to water with more than 11 grains hardness.
Temperatures over 135 can cause minerals in water to harden on metal surfaces of any water heater.

Also clean Tankless water filter each month, and clean and maintain burner and combustion chamber yearly.
The cost of maintenance and cost of expected repairs and cost of parts plus cost of original installation will never pay back the $1-8 monthly savings on gas bill. All costs are energy.
Make sure there is qualified service technician in area before buying tankless.

The water is coming out of our BUNN very slowly.What is the matter?


Your sprayhead and steel tube which connects to the sprayhead from the tank may have a lime build up. Simply remove the sprayhead and clean it with a wire brush and make sure the holes are clear of any lime or debris. In order to clean the tube which is what the sprayhead screws onto you will need a deliming spring. www.midstatebeverage.com

bunn perks coffee very slow?


This is generally an indication of a lime build-up in the water tubing. If you take off the sprayhead and insert the metal deliming tool into the water tubing all the way leaving out about 1-2 inches and twist it about 5-6 times, this should remove the lime deposits from the water tubing. Then flush out the machine with 2-3 decanters of water. If this doesn't fix the problem, then call customer service with the model and date code for further assistance.
