Worcester Bosch greenstar common water leak

Leaking from the domestic hot water sensor inside the boiler is a common problem with this model Worcester Bosch Greenstar CDi boilers .
Removing it can be but if a nightmare since it normally get stucked ... !
Never mind the PCB laughing with many holes to quench itself .. if water goes into the pcb you may get stuck again!
