Hi i have a problem with my dishwasher, when i switch it on & press the start button it seems to act as normal, i can hear the pump running and then the valve opening & letting water in, however 30 seconds or so after letting water it the following lights flash and the machine begins pumping out the water again: two red lights on the left which i think are the salt and rinse aid lights, and on the far right the wash, drying and end lights are also flashing.. tried to find what error this series of lights points to however had no success.. if anyone could be any help that would be great, thanks
