The diverter cannot be in any other position but the positioned to deliver water to ch port
The diverter valve can be in either of it's positions as determined by the hydraulic actuator.
The switch has an NC and an NO position.

That is a bit confusing to an electrican. A simple push switch is ON when operated, operated = the operating lever, button or pin has been pressed.A switch fitted to this diverter is operated by a shaft while the diverter is in said rest position. The switch in this operated mode is in the OFF state

Totally agree.There is only one correct way to describe a switch technically and that is NO or NC.
Oh FFS. Some will not accept the they're wrong and send up a smoke screen to cover their tracks. Good thread this.quiescent condition
The divertor could be stuck in the DHW position if the spring did not return it to the CH position when the DHW flow stopped afte the last time DHW was needed
What is it you are actually saying DP????.....that Agile is a pompous ****t?Sir you are contradicting yourself regards the diverter.
Re switch, it is drawn in circuit in idle state. That remains a fact, not what you say!!
The thread is about a particular appliance so everything on how it functions is important
What you say about other engineer's abilities is your perception only, not fact. Have you forgotten the pipe flattening advice by yourself? Clearly a no no technical/ engineering practice, again your perception but not practically factual
How is the boiler design mechanically oversensitive. I do not see it as such. Looks like you do as your contribution to this thread is contradictory at times.
What has upbringing got to do with discussion? There is no nastiness or swearing. Clearly we are discussing a boiler and how it works. I have reread the posts on this thread and found your earlier responses way off the mark. When a poster asks for help, any advise given has to be pertinent to the topic and helpful to the uninitiated otherwise it is of no use to them. Your upbringing is not pertinent. Contact designation i.e. NO, NC or C perhaps too technical to someone who is not technically minded, but they will always understand terms like switch being on or off.
The microswitch when released or off the diverter, will fire the boiler for hot water.
It would appear that during assembly the two core cable has been wired to the wrong terminals on the actual switch.The new switch, you are correct, is working in reverse.
Hence in the un-operated position the switch is closed. It therefore safe to assume that this "switch" ( which appears to be an assembly of switch, fixing horseshoe bracket and a two core cable to a plug ) is normally closed ( as when delivered in the package ) but "normally"open ( quiescent condition ) when fitted to the divertor valve and there is no demand for hot water.
