i am desperately seeking a part. I have been trying to order the part from aeg since march and have been sent everything but the parrt i need. it is a rubber hose which comes out from the dishwasher drain pump to the exterier waste pipe. the hose is a sort of s shape with both the ends turned down. i have been sent a similar part but it is half the length. that part number is 646 122 490 and it is definately not it. i have got that desperate i am considering just buying a new dishwasher. the dishwasher pnc number is 911 234 094 01. i would be grateful for any help and am prepared to use a pattern part if necessary[/img]
