CONCLUSION
Hopefully this mayhelp someone in future.
IT WAS THE PUMP. Not enough guts to get the pin on the diverter up into the microswitch enough. Replaced pump for £100 +£60 labour.
It was actually you Tony Agile that made me get someone else in to look at it after what you said.
I called Halstead Dimplex and got one of their warranty men to come look at it. He had it done within the hour.
Thanks for everyones help
