do I have to take dishwasher out to replace sump seal
Answer Carl, You don't really have to remove the dishwasher, But it's a lot easier if you do. Once you remove power to the dishwasher, remove the racks and disconnect the manifold from the pump accumulator, then you need to remove the kickplate and access panel, you can access the pump tabs, remove them, then disconnect the hoses and the wire harnesses and raise up on the pump assembly, and replace the sump gasket.
How do you replace the sump pump seal on my dishwasher? Can you access it from the top or does it have to be pulled out and access from the bottom?
To replace the seal you will need to access the bottom of the unit to disconnect the pump assembly. You will also need to pull 3 pins to get the sump out and install the new seal.
