Hi Andrew. The giggleurs are located inside a fitting on the left of the group head that feeds the banjo tube right before the water hits the coffee. I am uploading the Linea parts diagram book. The info you want is on page 20. You should be able to get at the fittings with a wrench from the top but some of the angles will be tight. Be sure to turn off the water and unplug the machine, which I'm sure you already knew but I had to say it anyway. You should also be carefull about really torqueing on the fittings. The copper tubes like to twist with the fitting when they are tight, which leads to pinhole leaks and flow restrictions. The tubes that feed the grouphead are especially fragile since they are so small and also act as the supports for the flow meters. Be sure to remember that a mistake that causes one of the groups to leak will take out the whole machine until that can be fixed. You might want to try changing one of the groups first and see if it achieves what you are hoping for. There would be no sence in changing out the rest if you don't get the change you are wanting. I hope this helps. Good luck and have fun!!

I apologies for sounding picayunish and all, but it is Gicleur, pronounced jeeclooer

Actually, no offense taken, but I believe it is a flexible term and spelling depending on who is using it. When you view a La Marzocco parts description it is actually spelled gigler, whereas if you look at espressoparts.com, it is spelled giggleur.

I have seen the many spellings, and heard some pretty funny pronunciations. I thought one coffee professional was coming on to me. I did not want him to jiggle anything near me, if you know what I mean. Other people make it sound as thought the espresso machine was going to laugh just a little bit while extracting.

The truth of the matter is that it is a French word which means "nozzle", and the verb Gicler means "to squirt". People have used different letter combinations to phonetically spell it the way Americans pronounce it, but we shouldn't apply the rule of interchangeability just because different sources have guessed incorrectly at it without actually looking into it.

I know that in the case of Espresso Parts, Terry Z has admitted that they spell it the way that is fun to write and say, which at least to me is more excusable than LaMarzocco's lazy indifference to the terminology of the fluid and hydrological systems industry.

You may have noticed by the spelling of my name, I am French. So I understand on a certain level how the French take it as a personal affront to their culture when Americans make no effort to have a little understanding of their language. But I am also essentially Canadian/American by culture, and I also understand, here in the melting pot, you never know where your terminology might be coming from at any given moment. It is not our fault if others pass along bad information to us, but once we know the truth, we should make some effort to pass it along.

Setting the aside the spelling/cultural lesson for the moment I have a different question;

Andrew, have you installed the "French Nozzles". Or at least one? I would be interested to find out if you got the desired result in the extraction.

I think we should call them "French Squirters". Way more fun to say or spell than giggleurs. or gicleur.

Call it a group jet, or how about flow meter?

I always thought that French was over rated anyhow ;-)

Back in my young Barista days, "jet" was what I heard our old technician calling them. I think I most often hear "flow restrictor" these days. If you live near the center of the biscuit, you probably just say "Rubies". Just don't call them "restrictor valves", since they don't open and close like valves.

So am I mistaken in believing that in order to get a flow restrictor jet hole installed in the Linea you need to tap threads for it? I thought you could not just screw one into the tube with the stock size.

Hey Phil,

Ruby jets are larger diameter, and were sourced for the GB series machines. A stock brass .006 will fit into the end of the three way valve tube on a LM Linea, if you tap the end of the pipe, and is how we do it on all EE series machines equipment with group jets.

Andrew, is your machine an auto, with the dosage pads or a semi-auto with just a switch to turn on/off the group? After reading this thread and looking back over the diagrams it will make a difference as to where you place the gicleurs. Since the diagram does not specify a placement for the auto, AV, unit I would assume that you would have to place them into the outlet of the flow meter. And perhaps tap the flowmeter to accept the threaded jets. If you have the semi-auto the gicleur will be in the threaded fitting I mentioned in my previous post. Please let us know how the project is going for you. I think we're all interested.

A metric tapping set is inexpensive and available at your local hardware or super home center. If you have never tapped threads before, it is not hard as long as you adhere to two basic rules.

1. Use a little oil to lube the thread cutter (a necessary evil)
2. Make two 1/4 turns forward, one 1/4 turn backwards, then two 1/4 turns forward, etc... till you have reached your desired depth.

If you just try to drive right down, it will bind up and damage something expensive.

Good luck!
