At your own risk if the element is ok...
How about swap (on the main board) the wires for the brew and steam thermoblocks. Careful as this will defeat your thermisters and the elements will not turn off. So only power on for 30 sec or so.
If the steam has warmed and the brew hasnt after swapping the wires, then you have a board issue.
If the brew still heats and the steam still doesnt, you need to look more closely at the steam wiring.
^If this makes no sense and sounds stupid to you- then dont do it.
The steam wiring is pretty simple. The element has power supplied 100% of the time from the power lead ( power switch may interrupt...cant recall).
Power runs through the element into the thermal fuse (actually probably the opposite way round) then goes to the board. So the board switches the return....
Confirm what im telling you by looking at the wiring yourself.
Only mess around in there with the power off.
Compare the steam thermister with the 6900 or the brew thermister when cold.
