Following on from my other post,

If my diverter valve plunger is not moving out enough, when the hot tap
is run, to operate the flow switch, do I need a new value?

Could this be a symptom of some other problem, such as lack of expansion
vessel pressure.

It's a Worcester CDi28 RSF Combi.

The vessel (see the FAQ below) is fine.
The water flow detecting unit is the problem.

Cheers, Ed, the FAQ was very useful.

By the looks of the manual, i'll need a whole new diverter valve.
