La Cimbali M28 Select - restoration
Decided to buy a used one, to restore, as a project during the Covid-19 lockdown.
Never worked on any espresso machine before.
Wondering if anyone could point me in the right direction.
I turned it on, heard a long beep and it started heating in setting 2.
Setting 1, filling up, was skipped since the boiler appeared full.
The boiler got really hot, started boiling the water, and I heard it turning off (a click so solenoid probably).
Then I could use the steamer and the hot water function.
The group heads only gave very little hot water and did so intermittently.
Based on searching this forum, this is because I don't have the water intake connected to the tap.
Currently, for testing, the stainless steel flexi hose sits loose in a filled bucket and is therefore missing the needed positive pressure.
I'll order a quick fit for garden hoses to connect the machine with my sink faucet in an attempt to solve this.
After using the hot water function a couple of times, the light for refill went on and I heard the pump trying to get water.
I turned it off a bit later, because running the pump dry probably isn't the best idea.
All, to me, seems normal up until this point.
However, the boiler pressure gauge read 0 bar.
I found that unlikely, and think the problem might be a faulty gauge.
After disconnecting the guage, and opening it up, some gunk fell out when I pressed the 'lever' and rotated the dial.
The problem is that it now sits at about 0.8 bar, for no apparant reason, even when completely disconnected.
> Is the spring in the gauge worn after 20 years and therefore not returning to 0? Should I order a new one or can it be fixed?
> No doubt my assessment isn't quite right, so any feedback is very welcome!
