The top element has failed with the middle burnt out. I have replaced this but have lost the paper with the connections on and do not know where to put the wires. Does anyone have a wiring diagram. I fitted the connections from memory and only the middle works even though the selector switch is set on full element. Changed connections about and the outer part works. Suspect that the selector switch is also faulty. Can you please send details of colour codes for element connections. Many thanks
