When on a rinse cycle the machine appears to take in the required amount of water goes through its first rinse and prior to pumping out the water it starts spinning and throws water out through the detergent dispenser housing. This happens on each of the rinse cycle.
power off, navigate to the rear, take off rear panel at bottom, by the pump you will find a rubber elbow, unscrew retaining jubilee clip, lower rubber elbow and inside you will find a plastic cup and ball clean this out and re-assemble making sure it fits in lug at bottom of elbow, connect back up and making sure jubilee clip is secure and power up and see if this has sorted your problem out, it did for me (checking and clearing it every 6 months now)
