I have a problem with the pressure relief valve which is in-built into the boiler cap - there is a tiny metal part which almost looks like a small circulat cap on the end of a pin which sits right in the middle of the inside of the cap/valve which has fallen out, and I cannot open up the valve to replace it. Without this piece, the boiler will not build up any pressure, and steam pours out of the relief valve. Is there an easy fix?

Hi,

You have to replace the safety valve with a new one.

I had the same problem of the boiler filling up all the way with water and the water was coming out of every hole in the machine. Turn the machine off, drain the boiler completely,
MAKE SURE VALVE #2 is CLOSED, this is the one under the drip pan all the way to the left. Turn on the water supply to the system and turn the system ON. The cup warmer on top will come on and stay on for anywhere between 10 to 20 minutes..... let it be,,, do not turn it OFF,, it will go off automatically. That should do it!

Hi there,
It seems to me that your pressure stat which is inside the base of your machine needs replacing. I would try to give it a good descale and if this doesn't do the trick then a new pressure stat is what you need. Prob around £20 if you buy it and do it yourself. www.theespressoshop.co.uk and just click on the little la pavoni machine for full parts list.

All the best

Hi there,
I am an engineer that services these machines on a daily basis. Good news - you are not missing anything at all. The type of cap you have, has a safety release valve built in which will be the hissing sound. If you fill the boiler as normal, turn on the machine and allow to boil up as normal and if steam starts hissing out and does not stop then just give it a light tap and this should stop. Basically when these machines are new the spring inside sticks and once you have tapped it a few times to release it, it should loosen it up and it will give a brief hiss then stop as the machine heats up. I hope this helps but if you have any further questions you can get me at [email protected]

All the best
