How can i fix my Potterton Performa 24 combi. boiler?

My Potterton Performa 24 combi. boiler will switch on and fire up, but will not switch off. For example: If i turn it on to heat the water only, it will heat the water, and then heat the central heating system. It will try to cut out, but cannot manage it. Therefore, it just gets hotter. Please help.
