I am replacing the orange pressure sensor on the Vaillant Ecotec Plus 824 with the new black pressure sensor, however the fitment seems much too loose on the black pressure sensor.
The black pressure sensor has come with a thin locking pin, the washer, the sensor and another thicker locking pin. I can see where the washer, the sensor and the thin locking pin can be fitted but what am I to do with the thick locking pin, if anything at all?
It seems that the fitment on the orange sensor fits snugly into the hole whereas the new black pressure sensor seems to just sit in the hole and has quite a bit of movement, even with the think locking bit in place. I have put a picture of the pressure sensor that i am trying to fit - is this the right one?
