Perhaps you have the book on this boiler and can advise what code 07 relates to?

Without that information I would look at two things, the resistance of the DHW temperature sensor and the temperature differential across the plate heat exchanger in DHW mode, that should not exceed about 30*C unless the pump speed is low or the HE is blocked.
