Unplug, cool down, remove carafe and basket, turn unit horizontally over sink. It will drain faster if you remove the screw on "distributor" (nozzle). OR do not drain. Just add the plastic pitcher full of a 50% white vinegar solution, let heat then turn off for 1 hour. Drain OR add 4-5 pitchers of cold water to rinse.

How do I drain a bloomfield 8571?


I would remove the big fat rubber elbow from the tank going to the fill basin...and turn the brewer upside down in my sink. This is how I drained about ten thousand of them (not joking about the ten thousand). But it depends on what you are doing. Did you want to delime it? Did you pour coffee in it by mistake instead of water?....What ever the reason be sure you let it dry out good. Coffee machines are use to flooding, spraying internally, leaking and they are built to shut down breakers. If you are pulling the tank or just removing the top, you may want to leave the water in to see how much water vs lime and sediment fill the tank. Depends on where you live. Enjoy.

Tip

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

My Bunn CWTF-DV-3Tisleaking water from the top right corner of my machine,and has just started leaking at the base of where the bottom burner is. Could you please help,as we have no technicians were we...


open the top. there is a trough drain that gets limed up. using a phillips head screwdriver, push through and twist, thereby removing the lime and ensuring proper flow. if water can't get through, it may overflow over the sides of the trough. also look behind the trough to the top of the tank and see if there is any water damage around the seals. if there is, replace the seals

water tank inlet in the top possibly limed up causing pan to overflow. remove top, use screwdriver or deliming spring to poke through the drain nut in the pan. should work fine now

Service error #21


I believe that is a water sensor error...your machine may be coated with lime preventing the machine from sensing water...generally if your unit is plumbed for water the boiler would need to be removed and de-limed...if you have a "pour over" unit...then try pouring white vineger mixed with water...50/50...into the normal fill port...let it sit for an hour or two and drain or flush...the vinegar is a safe way of dissolving the lime...phillip

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...


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.

My bunn vlpf coffee maker the water tank is overheating to the point of steam is spewing fro the air release tube... I'm thinking thermostat ?


You are correct.Also check the tank for lime.By unplugging and removing top of machine (2) screws and remove fill basin.You can then remove your t-stat probe to check.If it is lime up you can crack off the lime and reinstall it in the tank.If limed up I would suggest de-liming.T-stat part# 4314.0001.

WE have the Bunn VPR series. It's a pourover


Hello this coffee maker has a one and a half gallon internal tank, could be one of a few problems, first thing to check is the spray head, unscrew this you may need some channel locks to get it off and check it..use a tooth pick to clear the 6 holes with any lime that may have formed...also if you use a commercial coffee company for your coffee they should have supplied you with a spring to clean the spray head tube. After checking these 2 items the next thing to check is there enough water in the tank..when the vpr is left on and not used for a few days the water in the tank evaporates..it takes approx two and a half pots of water to fill up the internal tank...try pouring another pot of water in...also turn machine off and take the 2 screws out of the top and see if there is lime blocking the drain hole in the fill pan. Hope this helps...please feel free to comment again if you have any other questions...Good Luck!!! Mike
