its a boiler that pulsar sell it has many strange designs like a heat ex that comes out flips upside down and empty's in a bin bag best thing you can do is contact wolf see if they have a system like BAXI or Worcester x amounts of repairs for a set price its a very obscure boiler

Have worked on other models of Wolf boilers, In my experience they need a full strip service about every 3 years, which req's a service kit, which has gaskets overheat temp sensors etc.
If the heat exchanger is getting bunged up it could cause the boiler to over heat.

I'm having a similar problem with the same boiler and posted it in the gas safe section.
Any help with fault finding would be appreciated.

Yes but it's about 20 miles away with no phone signal so any little pieces of information I could gather to save me heartache are helpful.

whats the fault symptoms?

Pump runs for 30 secs on start up then goes into reset. Fan does nothing but had no equipment on me as I wasn't working when I called he flagged me down!
No access to fault codes fir the troubleshooting I've just seen in the MI's.

well start with polarity,do the mi,s give thermistor readings etc?

 

[EPH]

Not that I can see, just very basic fault finding from error codes that aren't displayed on the boiler

 

[Billy Bob Bob]

take the readings of the thermistors around 11k cold but can vary with make,can you post me mi,s i can take a look at its internals and advise from there
