My maytag dishwasher has been fixed over 8 times in 5 years.  First the top rack will stop working and then the rest will follow.  Even with a warranty that I purchased, it has been a pain.  The final straw was when it took 4 service calls before it was fixed right and Service Net the company that I purchased the warranty through, called to say I was over the 800.00 limit for repairs on this dishwasher and refused to send another technician out to fix it right in the middle of waiting for a part to come in.  Never again!
