Ok My Worecester 280 packed up today, seems water is leaking out from (what I think is) the water temp sender unit [ Item No 32 on the Worcester 280 parts list pdf). It's sited on the hot water pipe that has an air bleed valve sitting on it at the top of the boiler. Must have shorted something as the RCD tripped.
Its now disconnected from the power supply.
I've reduced the pressure in the system by bleeding a rad to stop the drip.
The valve looks accessible, but how easy of a fix is this?
Are the parts easily obtainable?
Comments and thought welcome ..
