Tim for Model Number 665.13743k603 I found a loose o-ring around the lower arm in my dishwasher. The color of the o-ring is blue, it measures around 7-8 inches in diameter and the sides of it are flat. I think its called a seal ring (pump cover). I am not sure if I should try re-install it or get a new one. Also, I am not sure what it came off. Thanks.
Answer Tim, There is not a blue colored "O" ring or seal, that large ( 7 to 8 in.) in your dishwasher. Are there any issues with washability, or major leakage. Good Luck and Thanks Read More... Answered by AppliancePartsPros.com | Friday, November 25, 2011
