Baxi 100/2HE Flow switch leaking

[mustard]

I have a leak from the black flow switch when the boiler has cooled down, it amounts to more than a jam jar of water over night & is yet another example of poor Baxi engineering,,, access to change the switch is not simple due to tight fit of surrounding parts, & system drain down etc.
Any advice & comments appreciated please before I call my local RGI. Thanks, George.

Yup.....drain down strip and replace o ring......nothing else will do i am afraid.
