Marzocco FB/80 exploding pucks

So the problem is that when I pull bad shots with a really course grind my pucks come out great. But when i set the grind to pull 23-27 second shots at two ounces (as per my espresso) the pucks always come out soaked and exploded. i was told it was a problem with my espresso machine. Why does it do this?

Check the shower screen and water flow. Press the brew button and watch how the water flows, is it a nice shower or a blob of water, is it in the middle of the screen or close to the edge. Also check the groups where they are connected to the boiler, if it is welded skip the bottom great, if not and there are gaskets, nuts and bolts, and water is flowing on the edge of the screen then it is possible that the diffuser gasket needs to be replaced.

Lesson


Hi I have one of these and I know it is frustrating at first. There is quite a lot out there on the net about \'pulling a great shot\' some of it conflicting some of it intensely obsessive.

So here is one I found useful

http://coffeegeek.com/proreviews/detailed/pavoniprofessional/operation

I will also try to tell you what I believe will help you get going.



Number one buy decent coffee.

Like all espresso makers it the combination of grind and tamp that will lead to a good shot, this is especially true with the La Pavoni.

You must grid your own beans for this machine, or at a push if you buy from a roasting house get them to do a selection of different (fine espresso) grinds for you, mark the packs and try them all and select the best. Here in the UK coffee sold pre-ground is just to course for this machine.

So if you are grinding your own you need to experiment and every time you buy new beans you will notice you have to do it again to calibrate the grind.

A grind will be to course or the tamp to light if the coffee flows to easily and takes less than about12-15 seconds with a relativity moderate pressure on the handle again this is something you need to get a feel for. you really don\'t want to be straining to pull the shot as this means the grind is to fine or the tamp is to hard, so it is possible to have a good grind coupled with a wrong tamp.

I tend to use just two finger to pull down on the handle this way I can feel more easily how the flow is going I also have a look at the coffee coming out of the spout when you have it just right the flow kind of bends at the top rather than going straight. Also it can be quite easy to damage the machine but pulling too hard on the handle.

If you find that you are pulling down for to long and nothing or next to nothing is coming out then the grind is to fine or the tamp is to hard or both. I think in general I would try adjusting your tamp first before changing the grind.

I suggest experimentation and stick with it, it really is worth it when you start to pull great coffee shots.

Also look out for overheating the brew-head this can lead to a bad taste it can get to hot after pulling 4 or 5 shots try wrapping a damp cloth round it for a while to bring the temp back down.

So I am sorry if I have rambled on a bit but there are no hard and fast rules here.



All the best

La Marzocco Linea 3AV...water is coming out of group heads but is not hot. The boiler for the steam is hot. Help?


Your front brew boiler likely has a dead heating element or there is a problem with the electrical system for the front boiler.

How do I increase grouphead pressure on la marzocco linea 2 group?


To increase dispense pressure you turn the adjustment screw at the pump. When pulling a shot (use espresso) on one group the bottom needle of the gauge should read 9bars while pulling the shot.

Water dripping from my boiler/dispensing pressure gauge


If it is leaking from the gauge then have it replaced ASAP. It is easy to replace, just make sure machine is turned off and cooled and water is turned off.

Waret Pucks


Hi There are 2 problems that can cause a watery puck. 1. Like EsWorld said, If the grinds is too coarse it leaves room for more water and you get a watery puck. 2. But if your grind is like a grain of salt, the you don't have enough coffee going into the brew unit, and this leaves room for extra water. To fix this, there is a lever on the top center of the door. The lever will increase the dose if pushed towards the back. DON'T push the lever to the full back position. This could cause an over charge, which could cause the brew unit to dump the ground coffee with out making because it could not compress the charge, or it could break the brew drive. 1 click back from the full plus is fine and will give a great shot.

No water coming out of the group head?


Your problem is either the brew solenoid or the brew switch.

Making Espresso shots... how does the macine do this? Not in man


www.partsguru.com look to the left for Saeco Home Models, select that, then go the model you have and download the manual.

On a magic comfort it has two settings for adjusting the espresso shot besides the amount of the shot. .

On a magic comfort plus,
you can adjust the grind size, the amount used for the shot, preinfusion (a short shot of hot water on the grinds before the unit passes all the water through the puck (coffee grinds), temperature and amount of water for shot

Also, when setting the strength on this machine, don't use a full grind amount as it can jam the machine. use a setting of 6 or 7 max for strong shots, not the 8 or 9 setting!!!
