Error e03 only drains when i scoop what i can

[Kreed81]

Hi i have a hoover washing machine only a year and a bit old. It has recently started showing the e03 error. If i open the valve only water comes out no gunk can be found inside. If i open the door and scoop out as much water as possible, then the drain cycle completes. If there is a decent amount of water it won't. Please help
