MattH From a bit of research seems it could be the vacuum breaker which I believe has a oring which can become brittle etc.
I have seen the replacement process on the mini - maybe I will see how easy it is to get too on the micra.. else call in a service firm !
Anyone else hitting that timeframe when items need replacing/tweaking ?
It could be the vacuum breaker, but you need to remove the lid and have a look. I think La Marzocco may now be using the same vacuum breaker as ACS across their range, if so, it’s reparable. @PaulL repaired his and may have even put an article up. The O ring can be purchased for very little money. There are 3 variants that all look the same externally, but may have a different internal O ring size..
It’s an easy thing to change, if you can reach the vacuum breaker and hope LM in their wisdom put a normal wear and tear service part in an easy to access position. 19 months is quite early for it to fail.
- do you run with the steam/service boiler on all the time
- do you use good water that won’t leave evaporative deposits?
