i have a sime boiler which is playing up. can't seem to get hot water even when I adjust the pressure. The pilot light ignites for the central heating but not for hot water. I can get luke warm water if I turn the central heating on but it never really gets very hot. any ideas?

As hundreds of posts have previously said, its likely to be the diverter valve!
And saying a "Sime" boiler is like a "Ford" car. A professional needs to know the model. Theres a lot of difference between a Ford Pilot V8 and a Focus!

It is a sime friendly format 80E...I can appreciate you must get asked this question alot
I have been trying to find a previous post regarding diverter valves. Does this mean that it needs replacing or is there something we could do to solve problem?

I don't know the boiler but the principles are that when you rut a tap flow is sensed and the diverter valve redirects the primary heating water from the radiators to a secondary heat exchanger the secondary of which your water for your taps passes.
Either the flow sensing mechanics or electronics are failing or the diverter valve mechanics or hydraulics are failing.
Or your secondary heat exchanger may be gummed up.
You have to investigate which.
If you don't understand any of the above you could take pot luck and thow above named parts at it until you have fixed it, don't stop there, may as well change pcb first, most people trying to avoid paying professionals go straight for that one before thyey ask on here,
or juct get a professional in.
If you didn't have such a complicated boiler (combi) you probably wouldn't have had any poroblems with hot water for another 20 years.
