Our Kitchenaid dishwasher is 6.5 years old and has started leaking from the door. We paid $80 for a repair shop service call. They really didn't do much except run the washer and say that most likely it was a bad door baffle or door seal. They called back with a repair estimate of $350 (parts and labor). Is it just me, or is this high?

How labor intensive is it to replace a door seal and baffle? The parts cost under $100, so this is over $250 in labor costs. I am just wondering if this is a 3 hour job. Is this something we could do ourselves? Are there any websites with video tutorials on how to do such a repair?

Any input would be appreciated. Would hate to shell out half of what we paid for the washer to fix it.
