Bad Taste after Descaling and Steam Wand won't work

Hi there, We've had a Delonghi EC460 for only a few months, and after an initial descaling (we live in Arizona with extremely hard water so we figured to do it a little more often), we haven't been have to have the same taste of coffee. The taste comes out bitter and almost undrinkable even though we've rinsed it out with countless rinsethroughs. We've even done another round of descaling with regular vinegar to see if that would help, and while it made the acidic taste less pronounced, it still doesn't provide the same quality taste that we got before descaling. What has happened to the machine? Are there any fixes or do we have a lemon of a machine? Also, the steam wand won't function properly anymore. We've cleaned it very thoroughly after every usage but for some reason it won't work. Not sure how to begin by fixing but could you point me to a manual that shows me how to address this particular issue?

SOURCE: steam wand not working


The steam wand ejects steam in order to froth the milk. The steam wand should be cleaned after it is inserted into milk and at the end of each day. Do not allow the steam wands to soak in water overnight since some of the dirty water can be sucked into the boiling tank inside the machine this may cause the steam not to come out
Unplug the machine, take the case off, disconnect the switch wires and test it with a continuity meter. If you don't get any continuity, or if it is constantly closed and never open, the switch is bad.
this could have been prevented by regular maintenance and proper use. The usual suspect is a gummed up wand or brew line or user error. Here’s what to look for and how to avoid it.
First, notice what kind of wand you have. Most semi-automatic and porta-filter espresso units will have wands that resemble those on bottom or right, although the tips may be different. Some tips do not slide up and down to alter the aeration, as the one on the bottom does. If your wand is from an older (1990s) unit, it could have a more bulbous tip and a smaller hole in the tip. wandte1.jpg wandte2.jpgSome of the new wands give you a manual/automatic control.
wandte3.jpg Many of the new super automatics come with an automatic frothing unit, like this one from Jura-Capresso. The nice thing about the frothing wands on Jura-Capresso's new units is that they allow for even more control.
The "Dual Frother Plus" (top) works like the traditional frothing wand. The metal sleeve goes up for steam, down for foam.
The "Froth Xpress Plus" is a very handy device which can be used with the included sleek milk container or a distinct milk container, like a 1/2 gallon jug. The Froth Xpress has a tube (hard for using the included container, flexible for using a different container) that fits into the frothing tube behind the dial shown in the picture above. After selecting froth or steam, the milk is siphoned into a cup below the steam wand. We recommend steaming the milk first, then adding the espresso.

Whatever sort of wand you have, it is essential to keep it clear of solidified milk which can gum up the tip and even the wand shaft. Here are some symptoms of a clogged wand:

  • Little or no steam comes out of the wand
  • Hot water drips from the tip of the wand
  • A squeal or whistle comes out of the wand when the steam function is selected
  • A deep humming is heard when the steam function is selected*
*This is also a symptom of another more serious problem, particularly if you have a pump espresso machine; so if unclogging the wand does not solve it, you should contact a technician.
A good preventative measure against the clogging of a steam wand is regular rinsing in warm, soapy water of the tip and any other removable frothing part. This should be done after each steam wand use. If your machine has a Froth Xpress, it is important to clean all of the hoses, valve, and connectors (be very careful with the plug, however, because it is delicate). All wands should also have steam jetted through them after a frothing cycle is run.
Another preventative measure is to run a steam cycle for about twenty seconds before each new use. This will eject stray particles before they can build up and cause serious damage. There is also a cappuccino cleaner available which can be used in the automatic frothing devices. The solution is placed in a reservoir, and a full cycle is run until the reservoir is emptied. This can be done every few weeks or every few months, depending upon use.
Aside from prevention, there are treatments for a clogged wand. First, remove the tip, if the tip is removable. Usually they are, as in the case of the plastic tips above. The holes are usually big enough to run a pin or even a small paperclip through (emphasize small) to remove the gunk. If these items are too large, do not attempt to use them; instead try using a thin gauge wire from an electrical wire strand. Next, the metal wand itself can have a pipe cleaner run up into it. Start out by putting just about a half inch of the pipe cleaner up the wand, rubbing it around, then pulling it out. Gradually work more of the pipe cleaner up the wand, but never let the length of pipe cleaner in the wand exceed the wand length. We recommend the pipe cleaners with the stiff barbs attached, as opposed to the mostly soft ones. Do the same for all of the hard hoses and connectors. With respect to rubber or soft plastic parts, rinse them in soapy hot water. If flexible hoses form holes, replacements are available (give us a call) or we've even had some luck at aquarium supply stores.
PLEASE NOTE: if you own the Jura X7 or the Froth Xpress Plus, the diameter of the tiny holes is very important. We recommend trying not to put pins into these holes. However, if they must be cleaned and soaking won't work, a smaller gauge wire, a single strand, should do the trick. Always use a strand that is smaller than the diameter of the hole.
Frothing wand technology is advancing at a breakneck speed, but along with these advances come serious precautionary measures for dealing with these very delicate mechanisms. Follow the steps above, and your machine should be producing full-fledged froth for its entire life.

Your problem is the holes in the cappuccino maker and
steam nozzle are clogged. Clean the holes in the cappuccino maker and the steam nozzle.

IMPORTANT: Before cleaning the holes in the steam nozzle, make sure that there that it is not hot and there is no pressure on the machine.

I'm sending you a free pdf manual download of what I believe to be your machine. If this is not it, give me the model # and I will try to find it.

Good Luck!

Jim

Red light flashing fast


The main reason for the Fast flashing red is with the water flow meter.
located at the back part of the machine below the power connector - its functionality can be checked in diagnostic mode .
see attached pictures
its either stuck due to in proper descaling or have corrosion in the connector contact of the flow meter.

Ascaso dream wand wont heat or steam


You should descale the machine, as you may have a blockage in the steam tap.
When descaling make sure that the descaled water goes through the steam wand as well as the group. JURA descaling tablets

Cant make hot milk or foam ascaso dream the wand doesnt work it just stopped. also my coffee is not hot, only lukewarm ive opened it up and everything looks ok, its all just electrics all of which look...


Hi Mike,
You may have 2 issues.
Steam wand may be blocked;
Try descaling the machine 1st before you do any thing else.

1.Try removing the steam tip, if you don't get steam with tip removed, try removing wand, if you don't get steam then the steam pin may be blocked.

If after descaling coffee is still jst warm you could replace thermostats http://www.bluestarcoffee.eu/ascaso--boiler-thermostats-x-2-193-p.asp

If you still don't have steam after descaling and replacing thermostats then you may need to replace the o rings on steam pin.
