Not hot water

[Parkerdkp]

Hi.. I have a Trianco combi external oil boiler.. the problem i have is that i cannot get any hot water unless I turn the central heating on. If i turn any of the taps on ( mixture between normal and mixer taps) the boiler wont kick in. I have had the diveter internals changed but no joy. It looks like the pin movement isnt enough for it to hit the micro switch?.
Any help on this would be most welcome..

Hello,

I’m not sure if oftec works the same way as GSR for advice, so you may not get an answer.
