Check/change the pump, or if its the same person diagnosing the fault as doing the flushing then maybe it should be done again properly.

overheats on ch,within 5-10 minutes of start

If everything gets warm i.e radiators then it could very well be the HE. Suggest cleaning it again. What did you use before and for how long?

 

[fin6969]

all rads get warm. was cleaned with sentinel x400 left in for a week

If you run hot tap for 5/10 mins does it still overheat? If so I would suggest new main heat ex.

Other fault could be no pump over run if this model has it, but new pcb should hace fixed this!

Could be cheaper option to call worcester in on fixed price call.

 

[fin6969]

hot tap running for 20 minytes going ok. perhaps worcester is the next step

 

[gas4you]

Doesn't sound to me like heat ex then. Must be something on ch side. We'll all have to have a think

Unless you are good enough to prove its the pump can I suggest that it could be the PCB as I had one several years ago that evey man and his dog had been to which turned out to be that.

I guess it was easy for me because I had a meter on the pump supply when it went off.

Hi, just seen the thread on this and was wandering if worcester managed to sort it, and if so what was it they said it was? Very curious as I've had nearly exactly the same fault before. Thanks

Hi Fin 6969! I'm interested to know what your problem turned out to be?? Did Worcester sort it in the end? I've had a similar problem but didn't get to go back to it as they changed the boiler! Cured the problem though
