I doubt this is true, because modern electronics are so highly integrated that it would be quite difficult to remove the SMD, or possibly BGA CPU/SOC, and particularly in a washing machine it would be encased in silicone or some other waterproofing.
I'm not sure why more-modular electronics are not more of a thing.
For example, blue-pill STM boards are very cheap, because they are produced in millions. Similarly for many other modules.
How is it cheaper to design and produce a relatively limited run of integrated, custom washing machine control electronics, instead of a simple 'baseboard' and a bunch of really-really-mass-produced modules?
The later modular design would be a boon for legibility, repairability, re-usability, supply-chain resilience, etc, etc.
