The machine is top-loading Samsung WA55H4000SW 5.5 KG. It's about 4-5 years old.
Seems it could do with a thorough clean (instead of the regular tub clean it regularly calls for and gets) so I've been studying various methods.
Anyone have a favorite chemical system?
Anyone taken the disassembly route? This one is obviously more thorough, but I don't want to end up needing a new machine because I couldn't reassemble the old one.
