i have a Hotpoint aquarius WMA30 which i have just brought from another house. when i select a cycle the machine starts to fill and stops when the water level is approx 1/3rd of the way up the door and the prewash light starts to flash. when i press the start button again the machine fills up to approx 2/3rds up the door and starts to leak. when i looked in the manual the prewash light flashing indicates the machine is not filling, but obviously is.
