WhiteKnight CL797R PCB dry joint (black mark)?

Hi,

My tumble dryer is starting upto the first rotation, then stops. I have checked the pcb and can see that it has cooked on one of the pins for one of the EBERLE AC250V 5A relays. Are these pcbs available to buy separately and / or is it possible to buy the relays as a separate part to solder onto the board.

Regards

Nigel.
