How do I get hold of a manual for my Genesis Jet Steam Cleaner... moved 4 times in 3 years and cannot find mine. Haven't used it in these 4 years and cannot remember what the citric acid is for... ple


I checked the verimark web site and unfortunately they don't provide access to manuals for their products... Steam cleaners generally are pretty simple, fill them with clean (preferably distilled or demineralized water) and use the stem to clean. Occasionally the heating tank can be cleaned with a weak acid to remove deposits - typically I use acetic acid (vinegar) but I guess a citric acid solution would work as well.

How do I get the yellow clean light to reset on a mr coffee


The clean light indicates that the machine has too much hard water, mineral scale built up inside. Follow you User manual instructions to dissolve the deposits using vinegar or a citric acid cleaning solution recommended for coffeemakers.

Steam wont work on my coffee machine


If you've used the machine for awhile, and you have not cleaned/descaled it, it may be clogged with mineral deposits. Citric acid, a white natural mild acid is a good descaler. It comes in powder form and readily dissolves in water. You can locate citric acid on the web (ebay). White vinegar also works, about 1/2 & 1/2 with water. Run the solution through the machine to descale it. It may take a few treatments to get all the mineral deposits out. Use about 2 tbsp of baking soda in water afterwards to neutralize the acid.Hope this Helps!!

Descaling rancilio


Use Citric Acid.

  1. Dissolve about one tablespoon of citric acid in the water reservoir.
  2. Fill the boiler completely. Open the steam valve and start a hot water cycle until water comes out the steam vent. Stop the hot water cycle, close the vent.
  3. Let the boiler heat up about 5 minutes. Then turn off the power.
  4. Let the acid solution work for about 1/2 hour.
  5. Pull a 30 second shot to change the water in the boiler.
  6. Repeat flushing cycles (steps 3, 4, & 5) until the water looks clear. Refill the reservoir with water and acid as needed.
  7. Wash out the water reservoir.
  8. Pull 5 or shots to get the acidic water out of the boiler. Run a hot water cycle to clean the acidic water out of the steam vent.
  9. Let the unit come to temperature and look for leaks.
  10. Make some coffee and look for leaks.
  11. Froth some milk and look for leaks.

Citric acid


The primary source is citrus fruits (hence the name). See http://en.wikipedia.org/wiki/Citric_acid

Delonghi coffeemaker dcf6214t clean light won't stop flashing after descaling how do I reset it to default ettings?


Hi, Cathy,
Most of the above solutions do not address your DCF6214T drip coffee maker. I had this problem, also. The manual is useless on this subject. The support telephone did help somewhat, but, also referred me to the website where I found the same useless manual.
Try this:
1. fill carafe to the 14 cup mark with warm water. (aprox 2L)
2. mix in 2 tablespoons of citric acid (a white powder available at Indian supermarkets) mix to dissolve completely.
3. pour acid into the coffee maker. and mount carafe in the machine and close the door.
4. with the on/off light off, and the clean indicator flashing press the clean button. The machine will fill the carafe over the next 3 hours, giving the acid lots of time to dissolve deposits.
5. After the on/off light goes off discard the dirty acid, rinse and refill the carafe with clean water. Fill the machine with water then mount the empty carafe in the machine.
6. With the on/off light off and the clean indicator still on, again press the clean button. This time the carafe will fill in about 6 minutes, as this is just a rinse to remove the acid.
7. Repeat 5 and 6 two more times. (I did it 3 more times, for a total of 4, but I believe 3 should work, according to the manual and the telephone support line.) (That is one acid clean followed by 3 rinses, all without pressing the on/off button.) (After all this, the darn clean indicator will still be on and the on/off light will be off.)
8. Now, make a pot of coffee and breathe a sigh of relief as you notice the clean indicator finally, turn off.
I hope this helps supliment a total failure of the manual to explain how to perform the clean operation.

HOW TO CLEAN


if scale is the problem you can take out tank and clean it with muratic acid or if it isnt to bad you could mix up citric acid and run a few pots through.

How do I prime an old machine that's been sitting in my cupboard for awhile??


De-mothballing a Senseo check-list:
  • Get some citric acid & prepare it as prescribed,
  • Fill the Senseo's reservoir with the citric acid suspension,
  • Place a large bowl underneath the coffee outlet,
  • Press and hold both small buttons, and
  • Press the Power button.
The citric acid suspension will now be pumped through the machine, into the bowl. To stop the rinsing, press the Power button again. I suggest you repeat this a few times, don't forget to swap the pad holders somewhere in between so they both get some suspension as well.

After that, repeat the procedure a few times with fresh water only to get rid of any citric acid in the machine - it will make a poor cup of coffee if you forget that step!

Coffee pot turns stops brewing in the middle of the cycle


Yup thats the Ticket - EASY FIX -
you have to clean the insides too people... lol.. The best way to do it is to buy citric acid crystals available from your local pharmacy. who knew huh? a couple of tablespoons in distilled water. Brew half the pot and let it sit for 30 min the brew the rest of the pot. Notice the color of your water after your done brewing. probably green from copper.. I could go into much more detail but thats the short answer... brew another pot or two of just plane ole water and bang your good go.. You should do this every month with any coffee pot for better tasting coffee..
