(1) don't mix washing and dryer. as with other All-In-One devices, one function breaks down means the whole thing can't use.

(2) don't mix washing and drying especially when you are using with (huge) family. why waste time waiting 1 load to finish end-to-end when you can multi-task in parallel with 2 separate machines.

(3) between japanese and korean brands, choose japanese for it's longevity and reliability. though not wrong to choose korean if you are the sort of person who changes devices every year or two 😅
