Vaillant Ecotec 832 Dumping Water

Hi All

Hopefully someone can help me. We have a Vaillant Ecotec 832 combi boiler, every few days the boiler will dump all of the water out of the system.

An engineer has been around twice but can't find any fault, any suggestions?

Many thanks

    Dumping where? Through a pressure release valve? If it wasn't ALL water, I'd blame the expansion vehicle. How do you know it's ALL? If this really is the case, then the valve is the prime suspect.
