I've had a similar problem, the hose between the impeller housing on the motor wash pump and the dishwasher had cracked and was leaking. I tried to repair the hose but it only lasted about 3 weeks before it leaked again and tripped out the motor. I've looked around to try and order the impeller housing but can't find the part I'm after, everyone seems to just stock the complete motor wash pump. Can anyone tell me where I could order this part or maybe a replacement hose which I'd need to adapt. It seems a pity to have to order a complete motor because if that is the case I may as well replace the dishwasher, all for the sake of a leaking hose. Thanks for reading.
