The washer has knobs and it also has touch controls, which oddly enough seem to indicate sensitivity to conducted EMI on the Whirlpool front-loaders (like mine). Probably the same on yours.
So - one easy thing to try is a Tripp-Lite IsoBar. Get the 4 or 6-plug version with cord. The two-plug, direct-plug-into-the-wall version tends to break in an unsafe way.
This solved my problems: (6-outlet with indicators)

You did NOT indicate the dryer has ANY problems, so I presume that's OK.
Oooops! My wash is ready. Time to put things in the dryer. I'm working 10M right now at 200 Watts, FT8. But most of my intermittent problems were on 40M.
Good luck!
