Indesit IS70C leaking - help please?

When operating, there is water coming from the condenser unit at the front left of the machine, enough to leave a puddle on the floor.
Have emptied the reservoir, cleaned the fluff filter by the door, removed & cleaned the condenser unit, checked the black & white pipes to and from the reservoir at the back, reset the thermostat on the heater unit and cleaned all the fluff that I could see. Any ideas gratefully received.
Thanks in advance!
