Sime Format C - Are we the only ones ?

My Sime Format C 100 seems to have hot water for a while and then goes cold.
Furthermore the summer setting does seem to do nothing.What is th problem ?

Please help , we have just moved into our new home.

The problem could be your diverter valve diaphragm.
Parts cost £5 but labour should be 2 hours !
