Check all hoses and hose connections - stretch them to find pinhole leaks. Closely inspect the pump, particularily where the pump chamber and pump body mate. Look at the seals around the heater and thermostat at rear of drum. Check the detergent dispenser and inlet pipe for blockage and overflow. Check for rusty spray around where the pulley shaft enters the outer drum - early indication of seal and bearing failure. Check the doorseal thoroughly. You may have to run the machine with the cover(s) off to try to identify the source of the leak.
