i take it you cant hear the pump working then?
in that case check your fuses first, cheapest remedy
do you have a rear wash wipe on yours?
if so consider swapping the pumps over if the rear one still works, failing that maybe pm dave johnson to see if its the same as the ukdm ctr pump, maybe get a price off him or consider a trip to a local scrappy if its the same
if not the same, then either order a new one from dave (guarantee he'll be the cheapest for a genuine honda spanking new one) or try pm'ing one of the resident breakers.....
