Help adjusting pressurestat on La Pavoni Professional

Postby Rich5ltr on Sat Jun 18, 2011 6:21 pm

Hi Guys, I have a La Pavoni Professional which I've owned for about 10 years. a few years ago I had the pressurestat replaced and since it has not run as hot before cutting off - about 0.8 vs 1.2 bar. I could take it back to the service agent but i) they are in central London 30 miles away and ii) they charge a £70 fee for each job - which is rather expesive so...

Can anyone tell me how to pressurestat? The problem is that the temperature of the water in the tank affects the pressure at which the steam emerges and being hotter and under more pressure makes frothing the milk esier. Thanks Rich... :?:

search the forum for info.. I think there are 2 kinds both are adjustable, some have a bit of glue on the p stat to dissuade you from adjusting it can be worked around. Many here will tell you .8 is ideal. I like running hotter myself so give er.
Remove the bottom plate and have a look it is fairly obvious. don't mess around in there with the Pav plugged in as you may get a shock.

Thanks for the reply. I have since done a bit of searching and there are indeed a few posts with pictures which is really helpful. Must confess I'm a little put off by talk of breaking the adjusting ring and some people seem to find the glue difficult to pick off. I guess I'll give it a try though. :? R...

There shouldn't be any glue if it's a replacement pressurestat.... :D

But bear in mind there will be a trade-off between sweetness of shot + speed of overheating on the one hand and ease of frothing on the other.

Frankly, I'd leave it where it is unless you prefer dark roast/robusta blends.

Cheers
