I'm lucky to have most, if not all, appliances lasted long long time with minimum or no repair.
The previous dish washer when we moved into the house in 1997 was at the very least more than 10 years old, it was broken about 4-5 years ago so it lasted more than 20 years. It was replaced with el-cheapo Sears unit for less than $200 with simple manual control. The new one is quiet and do the cleaning very well.
The front load cloth washer is LG I bought 3 years ago to replace the 12 years old front load Whirlpool, more than 10 year of use isn't bad. I bought LG this time because of the various rebates, so the final cost was about $230-250. The dryer is till working well after 15 years, the cloth come out dry and minimum wrinkle.
The new bottom freezer Maytag replaced the old one after 11-12 years in service, again I bought this frig mainly because of rebates, the final cost was less than $500 for a 25 cf frig isn't bad at all.
The gas water heater was installed 8-9 years ago to replace the 30+ year old heater, never do anything to it not even flush the tank. At about the same time I replaced the electric cook-top with gas with the same brand Thermador. It is working as well as could be.
In general, I don't have any problem with all my appliances, big or small. The toaster oven and the espresso machine are working as new after 6-8 years.
Sometimes you need some luck to have parts/appliances that don't quit on you.
