Wega Atlas heating element relay issue

I'm in the process of restoring a Wega Atlas EVD ./2-AT 'Cigar' machine.
I've discovered that the relay shown below - model Finder 40.31 - is burned.

The relay appears to be a control for the heating element, and is activated from a probe on the top of the boiler.
The machine was working when I disassembled it, although the relay appears to have failed in the open state.

I can't find a reference to this relay in the Wega electrical schematics. Does anyone have any insight into this relay and it's function?

Thanks

It shows it controls 250V 10A. So if you can find what the control voltage is (you can measure it), you can use an equivalent one and doesn't have to be the exact make/model. I usually replace it with a solid state relay so I don't have to replace it again (solid state relays last much long if they fail at all.)

Looks like this one is close enough, control voltage is 24VDC.
Or you can replace it with this one:

which costs 10 times more but will never break again.

Thank you I.Fix.Jura
The relay from my machine is line voltage input (250V - I am in Vietnam).
I can get an exact replacement - but I also have access to a solid state version shown below.

I assume this relay disconnects the heating element when temperature in the boiler is satisfied.
The original is a 'CO' (changeover) relay

That makes sense, probably using a thermostat to drive the relay.
Your relay is good if it's real (you are in Asia so you know). But by comparing with some pictures online, it may not be.

SSR's die all the time. Telling someone that it will never break again is a big understatement. Funny thing about SSR's is most of them don't tell you they have a latching life expectancy even though they have no moving parts.

If it's sized right and still breaks before the whole machine does, then one thing is for sure: it's made in China! Don't buy cheap things from there so you won't have your bad experience.
