Vaillant ecomax 828/2 e water pressure sensor?

Hi, I need to replace the water pressure sensor, I understand that it's a quite straight forward fix, can someone please guide me through the steps needed.
Thanks in advance

done
Drain the boiler, the sensor is positioned on the flow pipe top to the left of the main heat exchanger, remove the electrical connections (2) low voltage, remove the clip at the back of the sensor and pull forward.

Reverse the operation to fit new sensor
