Tip & How-To about Coffee Makers & Espresso Machines

Keeping the coffee maker clean

Coffee makers of all types depend on a tube to convey the hot water to the brewing basket. Filling the reservoir with WHITE vinegar and running a complete brewing cycle, then running a cycle or two of clear water (to rinse) will keep the insides of the coffee maker clean, and the tube clear of limescale or other accumulated impurities.

why does coffee come out while pouring in water its a bunn 10 cup coffee maker


The Bunn has a little stopper that closes the water drain port in the reservoir while the lid is open. You can see a little white plastic pin protruding up out of the grate with the lid open. When you close the lid, it pushes on that pin which causes the stopper to lift off the drain port, allowing the water in the reservoir to enter the heating tank.

If water is entering the coffee basket BEFORE the lid is closed, then something is wrong with that little stopper. It may have a chunk of debris on it preventing it from sealing, or it may be deteriorated, torn, disconnected, etc.

Only way to know is to remove the the screws in the grate and pull the top off exposing the reservoir, and the stopper assembly. The little plastic flapper disc should be seated in the reservoir drain port. It should be relatively flat (not wrinkled) and covering the drain port completely. Test it by pouring some water into the reservoir. If it drains out without you activating the stopper, then a repair is needed.

Move the lever up and down and check its operation. The arm must move freely and close when released. There should be no dirt or debris on the sealing surface of the flapper nor on the sealing surface of the drain port. Gently clean with vinegar as necessary. If the seal is damaged, then a replacement is required.

Doesn't always brew all the water, stops early


All coffee makers do this over time from calcium, lime, and mineral deposits building up inside the tubes and heating coil. Fill the reservoir with a 50/50 mixture of water and white vinegar and run a normal brew cycle, turning it off and on if necessary to completely empty the reservoir. Repeat this 2 or 3 times with fresh mixture of vinegar and water until it brews the reservoir empty without the need to cycle the power. Follow this procedure with plain water 2 or 3 times to clean the vinegar out. This should get it working like new again. It's best to use distilled water for brewing coffee as distilled water does not have the minerals that regular tap water has and therefore will not clog up the machine.

WATER LEAKS BOTTOM OF UNIT WHEN IS MAKING COFFEE ALSO, HOW DO YOU DECALCIFY UNIT? iS THERE AN ON LINE MANUAL?


Hi,
Below are solutions for a leaking coffee maker and how to decalcify the machine?
Tools and Materials needed to fix this problem are as:
* White Vinegar * Fresh Water * Volt-ohm Meter * Screwdriver
Step 1 - Clean
If your coffee maker seems to be clogged, try cleaning it with a mixture of white vinegar and water. Assuming that your coffee maker has a 12 cup capacity you will want to use 11 cups of vinegar and 1 cup of water. Fill the coffee pot to the 11 cup mark with vinegar and then fill it to the 12 cup mark with water.
Pour this mixture into the reservoir and turn on the coffee maker, allowing it to run through a brewing cycle as if you were making a pot of coffee. By doing this you will dissolve any build up in your coffee maker. If the coffee maker is leaking because the pump is clogged, then this might clear the clog and stop the leaking. If it has been a while since you last cleaned your coffee maker, you may need to run the vinegar through more than one cleaning cycle to dissolve all of the buildup.
Step 2 - Pump Valve
Unplug the coffee maker and examine the pump valve. If the pump valve is broken or has a clog, then the water will not be able to rise up and flow through the fill tube. When the coffee maker is turned on, the water needs to go someplace. If it cannot flow through the fill tube, then it may leak onto the countertop. If the pump in your coffee maker is sealed, you will need to replace the whole pump. If the pump is not sealed you should check it to ensure it is not clogged with coffee grounds or mineral deposits.
Step 3 - Brew Switch
Examine the brewing switch to ensure that is working. To get to the brewing switch, remove the base plate. Next, you will need to test the switch with your volt-ohm meter. Touch the tester to the RX1 scale. If it reads 0 ohms then you will know that the switch works fine. If it gives you a number other than 0 then it is time to replace the switch.
Step 4 - Tube Connectors
If the coffee maker is leaking or sputtering then you should take a look at the tube connectors. Many times, a leaky coffee maker is caused by faulty tube connectors. If you find the leak is in an elbow, clean the surfaces before you replace it. If the tube connector leaks, replace both the tube and the elbow so that you can be sure the pieces will both fit together properly.
To decalcify, you will be needing a : decalcifying cleaner and A container large enough to hold the same quantity of liquid as your water reservoir
1) Remove the machine's water reservoir. 2) Empty all liquid from the reservoir. 3) Fill the reservoir with warm water. 4) Add one packet of the recommended cleaner to the full reservoir and stir until the cleaner is dissolved. 5) Return the water reservoir to the machine. 6) Turn the machine on. 7) Set the large container underneath the steam wand. 8) Set up your machine so that hot water -NOT steam-will be emitted from the steam wand when the steam valve is opened. 9) Open the steam valve according to the manufacturer's instructions. 10) After all of the decalcifying solution has drained into the large container (within a few minutes this will occur), remove it and discard the liquid that has been collected. 11) Rinse the water reservoir thoroughly and then fill it with the type of water you usually use for brewing. 12) Return the water reservoir to its normal position. 13) Using only water repeat steps 7 through 9 until the water reservoir is empty again.
I hope the above helps....
Good luck.

will not process the water to make coffee


the coffe maker might be clogged up so here' what to do: Look through the clear plastic panel on the side of the coffee maker's water tank to make sure that it has water in it.
  • Clean your Sunbeam coffee maker, You can wash the removable filter basket and carafe in hot, soapy water and pour 4 cups of white vinegar into the water reservoir of your coffee maker. Start the brewing cycle with no coffee grounds to allow the vinegar to clean the inside of the coffee maker. Rinse away the vinegar by running the brewing cycle twice with only clean, fresh water.
  • 8 Check the removable filter basket to see if the filter has collapsed if you find coffee grounds in your brewed coffee. If the paper filters collapse often you can wet them before you place them inside the filter basket so that they will stick to the basket and stay in place. or check this link because it might need a new hose.

    Won't brew


    bring white vinegar to a boil and pour it into the perforated top, the water reservoir and the link between the water reservoir and the brew basket. let sit a few minutes, pour it out and do it again.
    put the water reservoir back in, put water and vinegar solution ( half and half) in. Try to start it again. Mine did this last year and this fixed it right away. Try to clean the coffee maker using the vinegar solution once a month to avoid this problem.
