Advice needed on washer/dryer sets

Seasons greeting everyone! This seems to be the time of the year when all the machines tend to break down. My wife and I manage 10 rental units on Kauai. I also do the maintenance on them. Since the guys who fix them know what to avoid I need to ask a general question regard washers and dryers. Since all machines will need maintenance at times, which machines have the least maintenance, easiest to repair and ready availability of parts. What brands and or models should I avoid. This is mostly at this time due to a broken GE stackable W & D unit that failed, but in general for all major appliances is there a brand or model that seems to keep running after others have quit.

Thanks in advance for your input
Jim
