Ikea DWh B10 repeated noise during cycle?

Hi, this dishwasher works otherwise fine but makes a repeated noise at two intervals during every cycle - it sounds like repeated releasing of the dispenser flap or something similar, and there is some mechanical noise which sounds like from a clockwork or similar - does nyone have any idea if this can be fixed within the £300 frame for a replacement dishwasher?
thanks
