Hello: Just bought Bosch dishwasher ( was going to go for Kenmore , but it is a bit higher so the decision was easy by process of elimination.Wondering if we should get the extended warranty 160 for 5 years? Is it waste of money? We are having major differences in opinion and I am wondering what is the concensus here on extended warranty.thanks and thanks also for helping out , many of you recommended Bosch so I am happy about the purchase..
