My Bosch Washing machine isn’t working very well – it won’t move to
the rinse part of any program.

Taking it apart, it looks like it has burned out a 470uF Capacitor
(400v) and maybe a small transformer (Marked “KA 19/04” and 063.783 )

The capacitor seems to have stained the circuit board and the
transformer seems to be covered in soot

Which would explain the burning smell :-)

Now, I think this transformer is the low powered supply to power the
brain (and the LCD) which is still working (!!)

Am I right about what this transformer is doing?
Does it sound like it needs replacing?
If I replaced it, might it fix the problem?
Might I just need to change the capacitor?

If I need to replace the transformer, can someone help me identify a
replacement as google seems to struggle with it.

Its about 15mm by 10mm and stands about 12mm off the board.
It seems to have 2 contacts on one side and a center tap on the other
– though this is not actually connected to anything.

Thanks
