Our Beko machine leaked due to the rubber pipe from the detergent tray to the drum chafing against the sharp seam in the machine casing, whenever the machine span. Eventually, it wore a hole in the pipe, so that whenever water entered the machine, lots would drip out of the hole. Bad design. I fixed the leak with bicycle puncture repair glue, squeezing some into the hole and pinching it together til dry. Then, I clipped a plastic book seam over the sharp metal edge to stop it wearing through again. Left the rubber solution a few hours to set properly before using the machine, which has been fine since.
You say yours is leaking 'from the top drawer' but it might be the same as ours was. Pull the mains plug out of the wall socket, then remove the top of the machine by removing two screws at the back, and sliding the top off. Then you can inspect the pipe from the detergent tray for damage.
