Bosch Dishwasher water leak

[h=3]Hello,[/h] [INDENT]I wonder if anyone could help me here with what seems a small water leak on my Bosch Dishwasher? Now I cannot seem to identify the particular model I have as all the identification details have disappeared from the door area. So if anyone knows where I might else find the relevant numbers of the model detail are that would be helpful.
The machine detailed the water leak fault the other day & in fact the float had tripped the switch as there was water in the lower tray. However I am struggling to pin point the route cause effectively so I can order the correct parts & was hoping perhaps someone else has seen this type of leak & has had some experience in identifying & correcting it?
I’ve attached a picture to try & show where I can see the water coming from, (white unit with the three brown wires) essentially as you look underneath from the front there is what I think, is the sprayer pump at the rear of the gray sump? The water seems to dripping from this reasonably slowly & has a rather faster speed of water loss momentarily when the sprayer starts perhaps? I’ve removed this item by the 3 small screws cleaned a small seal & refitted just to see if this made any difference which I didn’t think it would & it has’ent! As I say if anyone could through any light that would be helpful.
Many thanks[/INDENT]
