I have a leak in my dishwasher. I opened the bottom pan and I can see the drip. I was trying to figure out where the lead is coming from and I think it is coming from the back of the motor, from the pump. May be the pump seal needs replacement.

I would like to know if this is something I can do it myself and if there are step by step instructions for doing this.

Does the dishwasher needs to be pulled out? I don't really see any working space underneath to do the replacement.
