Krups XP4050 - Case example of support in theory
We had a query on a Krups XP4050 espresso machine that we sold which wasn't functioning as expected. In anticipation of receiving the machine I took a brand new machine from our stock line and set up the machine ready for use.
The first thing you notice about this machine is its level of automation at such a competitive price which should be applauded. You sense that the manufacturers are a little nervous of "real users". Upon filling the water tank the machine primes itself, that is fills the boiler with water automatically, which is fine as long as it works. In my case no problems.
However just to make sure I made a few cups of coffee and deliberately ran out of water, like many a "real user". This results in the pump sucking air into the boiler.
I refilled the water container and then went to make another coffee only to discover that the machine couldn't get any water into the boiler - it was air locked. I turned to the troubleshooting page in the manual and found ............nothing!.................yes that's nothing on how to overcome a simple air lock. Extraordinary!
For those of you who experience this problem the solution couldn't be easier - simply press the water button on the front panel. This has the effect of opening the boiler valve and forcing the air out which in turn is replaced by water and away you go.
The second issue about which there is no mention in the manual is if you experience problems foaming your milk for cappuccinos. Again all is simple in theory, and the principle used is one used on much more expensive systems, so it should work well. What I got was a lot of "spitting" hot milk and only a hint of foam. Yes I used fresh milk, yes it was cold but now what? Manual troubleshooting? - you'd be lucky
So I turned to the "helpline" who couldn't or wouldn't deal with the problem but instead offered to send me a replacement part. Now I don't know if I even have a faulty part, all I want is someone to tell me what I might try, to improve the situation - surely in the computer vaults of Krups someone has had to deal with this very same problem a zillion times, sadly if they have, Krups are keeping the information close to their chest.
A solution I found and not a particularly satisfactory one was to raise the milk container from which the milk is being drawn so that the flow of milk down the tube into the steam wand
was much greater. More foam was produced, however I still wasn't comfortable with the amount of milk that ended up in the cup.
So Krups whoever is responsible for customer care at your multi-million pound organisation, please take a long hard look at your manuals, particularly the troubleshooting bit and put some really helpful tips in; and when it comes to a 'phone helpline, please allow your support "engineers" access to the kind of information that might just help me a simple user.

The beauty of language
The Church was packed, the choir and congregation were in great voice and one got the sense that it was a wonderful community event. Community! such an old fashioned word in today's highly mobile society.
What though was it that made this service such a wonderful event? For me it was the language - the readings were mostly taken from the King James bible which turns the English language into an art form. The opening lesson from Genesis3: 8-15 with Adam complaining that "the serpent beguiled me"- What if instead of beguiled, the word "tricked" or "deceived" were used in its place? No sometimes the beauty of the English language is that we have a word when used in its correct context adds so much to the imagery and immensity of the occasion.
The language though that I wish I had learnt at school is Latin - the choir sang two pieces with Latin titles - "In Dulcie Jubilo" and "Laudamus Te "; it's so frustrating when you don't know what these titles mean so with apologies to all Latin scholars this is what I came up with from the dictionary: "Good Christian men rejoice" - incidentally there appears to be no "e" on the word "dulci" but I stand corrected.
As for "Laudamus Te", it appears to be a shortened version of the full sentence "Te Deum laudamus: te Dominum confitemur", which translates to "O God, we praise Thee: we acknowledge Thee to be the Lord." - a few words that mean such a lot.
The one hymn that I felt could be improved by not being sung in English though is "Silent night, Holy night", I've always thought that the German language gets across the magic of this hymn, not that I have much knowledge of the German language , I think it's just the sound. For the record here is the hymn translated:
Stille Nacht, heilige Nacht,
Alles schläft; einsam wacht
Nur das traute hochheilige Paar.
Holder Knabe im lockigen Haar,
Schlaf in himmlischer Ruh!
Schlaf in himmlischer Ruh!
Stille Nacht, heilige Nacht,
Hirten erst kundgemacht
Durch der Engel Halleluja,
Tönt es laut von fern und nah:
Christ, der Retter ist da!
Christ, der Retter ist da!
Stille Nacht, heilige Nacht,
Gottes Sohn, o wie lacht
Lieb' aus deinem göttlichen Mund,
Da uns schlägt die rettende Stund'.
Christ, in deiner Geburt!
Christ, in deiner Geburt!
Silent night, holy night
All is calm all is bright
'Round yon virgin Mother and Child
Holy infant so tender and mild
Sleep in heavenly peace
Sleep in heavenly peace
Silent night, holy night,
Shepherds quake at the sight.
Glories stream from heaven afar,
Heav'nly hosts sing Alleluia;
Christ the Savior is born
Christ the Savior is born
Silent night, holy night,
Son of God, love's pure light.
Radiant beams from Thy holy face,
With the dawn of redeeming grace,
Jesus, Lord, at Thy birth
Jesus, Lord, at Thy birth
It's a difficult decision for a Church in Jersey to sing a hymn in German on such an auspicious occasion given the history of what happened nearly 70 years ago, but surely that's what Christianity is all about forgiveness - I hope that one day we'll have the priviledge of hearing this wonderful hymn sung in what traditionally isn't a language particularly renowned for its beauty.
Now we move on to Christmas, and I wish all those who read my blog a very Happy Christmas and prosperous New Year

Ethiopian Coffee Trademarking & Licensing Initiative
Our job as coffee roasters is to communicate this wonderful heritage to our customers and endeavour to highlight those unique characteristics that come out of each origin by roasting the coffee as carefully as possible. In our case we sell Ethiopian Harrar as a single origin coffee, as well as using its unique characteristics in some of our finest espreso blends.
Where better a country to start such an initiative than in the true homeland of coffee.

Briel Espresso machine cleaning - updated
I was reminded the other day when two Briel espresso machines were recently brought into us that I first did a blog on this topic back in August 2006, however we still seem to be getting the same issues.
HEALTH WARNINGBefore you attempt any of the following take great care to ensure that you are aware of which surfaces are hot and give them time to cool down. When using any chemicals flush the machine thoroughly with clean water afterwards, and should you splash any chemicals on your person wash away immediately as they can be quite aggressive on the skin.
A further issue though was brought to my attention, that of the steam wand becoming blocked. This part is usually blocked for one of two reasons:
1. Scale
If it is a scale problem, "pray" that you can still get some water through the wand. If you can it means that you can get descaling solution into the heart of the wand by filling the water tank, then turning on the water pump and opening up the steam wand immediately. Once you see a trickle of water coming out of the end of the wand switch off the pump and turn off the machine. Leave for 10 minutes, then switch on the machine repeating the process of switching on the pump and opening the steam wand valve. If there's any justice the flow of water should increase as the scale falls away or is dissolved. Run plenty of clean water through the machine afterwards prior to using it.
2. Milk
The problem occurs because after the steam wand has been used no attempt has been made to "flush out" any milk that may have gone up inside the steam wand. Gradually this builds up to the point where it is impossible for any steam to escape.
We have tried chemicals in the past to clear these types of blockages, however because nothing is moving it has not proved to be a good approach. As usual the simplest methods tend to be the best.
You will need to dismantle any plastic attachments found on the end of the metal part of the steam wand. Check if any of the holes are blocked, they tend to be very small and usually only a pin or "unbent" paper clip will do the trick.
You can very quickly establish if the problem lies in the plastic section by checking if any steam is coming out of the metal part of the wand, if it is all problems lie within the plastic section.
However should the metal part of the steam wand be blocked you will once again need to use (and I have found this to be the best) an unbent paper clip to try to dislodge any congealed milk. Once you think you've removed any solid bits, let the machine heat up again and open up the steam wand valve. Pay a lot of attention at this point as you might find that nothing will come out immediately, however after a few moments the steam pressure may suddenly blow out the last vestiges of crusty milk so don't have your hands or face too near the end of the steam wand.
This process may need to be repeated a few times if the blockage is really bad, however do persevere we've usually got everything working again after a few attempts.
The lesson ultimately is that when you have finished foaming or steaming your milk always flush out the steam wand to air, otherwise you face the challenge of the above activity.
The following is a copy of my earlier blog
Briel espresso machine maintenance (Aug 2006)
We've had a couple of machines in recently which if our customer had been more sensitive to the maintenance requirements of their machine, we wouldn't have seen, so I thought it would be a good idea to highlight a couple of things you can do to increase the longevity of your machine.
The following refers in particular to Briel coffee machines, however the principles can be applied to all domestic machines.
1. Maintenance of the group head
When you take out the group handle and inspect the area from which the water emanates, you will notice a large brass screw. Around the edge of the screw there are a series of notches at regular intervals. It is vital that these remain clear of any debris, otherwise the machines pumps will be put under severe pressure, and you will struggle to make a coffee.
The main causes of blockages are ground coffee, and limescale.
When the machine is cold, use a short handled screwdriver to remove this brass screw. It's important that you get the right sized screwdriver, otherwise you are in danger of damaging the screw.
If you experience problems removing the screw, it's sometimes a good idea to descale the coffee machine first. This can help to remove any scale that might be causing the screw to stick.
When you have released the screw you will find that there is a spring and rubber "bung" that comes out at the same time.
This bung helps seal the boiler so that no water escapes into the group head whilst the machine is heating up. The spring helps keep the bung in position. So suffice it to say, don't lose either of these parts.
There are now a couple of things you can do. If you haven't already, now is a good opportunity to descale the machine, following carefully the manufacturer's instructions.
Once you have done this clean the notches that surround the screw with either an old tooth brush or some other tough scarifying material. Wash thoroughly after you have finished.
Once everything appears clean, replace the screw, spring and rubber bung. Hand tight should be sufficient.
Switch on your machine and flush through with water to ensure that any remaining loose material is removed.
If you use your machine regularly then you should look to do this procedure I would suggest once a month. In hard water areas probably weekly.
Remember, if you do have to switch on the machine at any point during the cleaning process ensure that you leave an appropriate amount of time for it to cool down before you continue working on it.
