So far we've had good luck with all but one DW since we married in 89. One lasted about a year and dropped dead. It didn't do a good job anyway so wasn't worth fixing. The next one lasted about 15 yrs. It was still working fine when we moved and sold the TN house. We bought a new one when we moved in here almost 3 yrs ago. It still works great.
We did have the repair man out twice for the combo washer/dryer. It was still under warranty so cost nothing. It's been working great ever since. It's getting a real workout with 4 adults here and a hot humid climate.
Companies these days have no pride in their products - just in making a profit.
