Bosch Wfd2090Eu Does Not Enter Final Spin

[rehud]

I have Bosch WFD2090EU.

It have switch to cancel last spin.

The machine does not get into last spin (everything else work's fine; it drains and spin at the middle of cycles).

I opened and checked. The said switch is not working - but it is OFF (no short-circuit between its sides). We actually never use this switch and do not need this function. The switch have two gray wires from both sides. the bottom one is short with two gray wires both getting into the main programs circular switch (they are also offcourse short with each other). I am looking for a way to permanently clear this option of last spin cancellation.

What should be done?
