Tripping mcb and rccb

[Ndagger]

Considering it's sole job is to make 60ml of espresso in each go its almost ridiculous right!

Note on the pic of the pcb there's a 4pin header labelled 'WiFi

Mental!

Does the machine self test all the heating elements etc when it is starting up? That could explain the trip on startup.

Spotted a few brown splashes , need to keep eye on motor cooling fans ! (Not meggered hot espresso liquid yet)
forgive my lack of enthusiasm -I drink tea.

Shaun1 - still waiting for info from the manufacturer on what the damn thing does during boot up, it's just a black screen with software revision printed across the centre, what it's doing in the background I have no idea.

Brown splashes are par for the course inside these machines, I take it you spotted the staining on the coil, those are very well potted and generally aren't too bothered by a splash of espresso, normal sign of them causing a trip (especially these 24v ones) are they swell right up

Have you noticed how many home produced products are inside this Italian manufactured machine - I have not seen 'Made in China/Japan' so far? The Italians are prolific electrical component makers.

Ndagger - I see that there is a yellow sticker on the side of the power supply informing the voltage can be set to suit the mains. Might be worth a check and comparing with mains voltage measurements I mentioned earlier.

A thought 'out-loud' is that if it is a switch mode PSU, then if the input voltage falls or dips suddenly it will compensate by drawing more current. There is often a significant surge when first powered-up. Once powered up the current waveform has a higher crest factor (= ratio of peak current to average current) which could trouble the type B mcb but not a type C.
