To repair the unit yourself you first have to find where the water is coming from. You may have to remove some of the covers and perhaps stand the m/c on stands to look under the m/c and with caution run the m/c to see where the water is coming from. On a different m/c I found that the plastic spray head in the centre top of the m/c had cracked and the water was running over the top, down the side and dripping from the bottom of the m/c.
