if you put your mind to it there is nothing you cant do.will suggest you open cabinet and first see if there is anything blocking pipe or drain pump,split pump assy from pump motor and see if impellor is stil secure.easy way to check if motor on pump is working is to put small piece of tape on one impellor and put direct power on pump motor,does not matter what wire goes where on connectors of motor,run the motor and hold finger in such a way to see if impellor is turning full circle.please be carefull with life power!!!!
