Remove the sprayhead and check that for blockage. Pour water into the reservoir with the sprayhead removed to see if it flows. If water flows then the problem is the sprayhead. If no water then it is the brew tube and you need a deliming spring to clear out debris. If the only time water does not get through grinds thne it is possible the grinds are too fine.
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
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
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
Remove the sprayhead from above the filter basket (when cool) and check it for clogs. You can soak it overnight in a dish soap solution and it should be easier to clean. Rinse it well before use. You should also **** the siphon tube (just beyond the sprayhead) with the deliming spring.
Try taking the filter out, and turn the sprayhead off the unit. Put the basket back on, and try pouring clear water through the unit. If the water runs through fine, you either have a plugged sprayhead or are using too finely ground coffee. Look at the holes in the sprayhead, and make sure that none of the holes are plugged. If the basket still overflows, try using a drill bit to make the hole in the funnel a little larger. Good luck.
Remove the sprayhead and using a paper clip clean out the holes on it, then you should have a long spring that came with your machine use that in the hole left open by the sprayhead, make sure it goes in all the way through up to at least 2 inches left in your hand, then run it a few more times. After that is done reassemble and run a pot without coffee.
You might try putting a butter knife underneath the sprayhead to remove it. If this doesn't work, then please contact customer service and request a tool that can be provided to remove the sprayhead.
