Both yellow is live? Or one of the yellow is live? If one yellow is live another not,  than someone wired wrongly.

If both yellow are live,  maybe the boiler wired to a wrong set of wires

One yellow is supply.

That mean the person who install for you just make it permanent on earlier.

Uhm.. Previously they install 2 yellow and 2 black under inlet. Which work fine.

Becoz the click damage, i change a new one which is on the video and photo.
But strangely, i follow back OR wire all 4 holes correctly will give me hot water no matter i switch on and off...

Am i instal wrongly as in the video?
