La Pavoni Europiccola 1977 (2.0) rebuild

Recommended Posts

So the addition of the adapter nut and length of the glass tube blocks the upper sight glass return: it causes a vacuum in the tube that prevents air from moving into the boiler until enough pressure is built up to push the air through with water.

 

As this did not happen with the old glass, it means this tube is slightly longer. I read somewhere that there's about 3-4mm difference between the old and the new oem replacement.

I'll shorten the tube and try again with the new 12mm adapter.

 

Careful with that...

In Austria we have a saying that translates to something like "now that I’ve cut it off three times it's still too short" :D

Latest update: it works!

 

I finally bought the 12mm adapter that is a lot shorter than the 11mm. This does not block the water flow and with a bit of threadlock there is no leak now: success!

Thanks everyone for your help!

Although it sits close to the shoulder of the boiler, it doesn't actually touch it, as the image may suggest.

Well done on the restoration, must have been fun for you.

 

These machines really are brilliant to look at.

They’re also brilliant to make coffee with

 

I maybe wouldn’t want to fiddle with mine each morning (given its age and condition, that’d be outrageous in its own right), but really enjoying the process for a relaxed afternoon or evening cup, every now and then.

@ricca509 indeed nice work and setup!

Now on to making coffee with it! (although I briefly used it before installing the gauge and it was brilliant)

just wondering, what is the warmup time of the La Pav on average, does it tell you when it is ready? (i have heard to listen for a hissing sound)

 

If its a twin element then put it on II untill it just starts to hiss then switch to I - flush the group head to give it a quick clean and heat up, at which point it should be nice and hot, 5-7 mins from cold usually does it


keep calm and grind flat

My La Pav Pro (1.6lt/16 cup) with the water to the top of the sight glass and an ambient of 14C takes 10 to 11 minutes to reach operating temp. This of course includes the false pressure release time.

ah how would I know if its a twin element or not? But definitely sounds like a good time to warmup for me! Have you measured what temperature it reaches at the point of the hiss?

keep this bookmarked - will give you all the info you will need http://www.francescoceccarelli.eu/lapavoni_ep_eng.htm

 

The temp of the water varies on a couple of things - if its a twin element or not, if the group is fully heated - in some ways the pav is more variable than most machines and the development of a routine, timing and understanding are required to get the best out of it.

 

any of the pavs can do the business but they require a certain amount of experience - its what makes them rewarding for many but frustrating for others

 

each one is a little different, with the pre 75 having what some to believe is the best group others disagree, all part of the fun!

The temperature I measured on my '74 is between 50 to 60 degC at the time of the hiss (at about 1bar of pressure). I normally then switch to 1 and leave it until it gets to 83-84 degC then pull the shot.

Time about 15' from when I turn it on to when I pull the shot.

What are you using to measure the temperature? Is it easy to measure?

Thanks for the help! How long have you been using the La Pavoni for, and any reasons making you wanting to upgrade?
Since 2016, I've used everything from a 62 pav to a 97, the only reason to change is to try something different say with a spring like my current microcimbali, are the shots better? A little bit, but I'm going to sell it soon and try something else, having said this I keep a 97 pav as my fallback machine. The thing about pavs is they hold almost all of their value as they are all fully repairable and devoid of electronics to mess up.
