Ok the rippling sound is for user faults that the user can check & usually fix themselves. In your case the blinking hot & cold lights give the clue. It is saying it is not getting any water or not flowing in fast enough. Check both taps are fully open if doing a warm or hot wash. Cold wash only needs cold tap fully open. Also remove hose from inlet valve on machine, point end of hose into sink & open tap. You should have a good strong flow. Next check the filter inside the opening of the valve before putting hose back on. Then try a wash cycle & see if the water flows in quickly. On this model you can open the lid & watch. If it is only dribbling in & sounds like it is straining (hissing sound) then you need a new inlet valve. If it is now flowing in fast then problem solved.
