With all due respect, this is an audio forum.
You’re talking about washing machines.
voltage spikes or sags can reduce the effiency of all connected electronics. Seems like a power conditioner would be useful for that machine, and also perhaps your audio system.
Check out my profile or send me a message if you want to chat about what I consider to be state-of-the-art, all at a reasonable cost.
Since first acquring it, I want more people to experience it. Faster charging for any smartphone (with or without Power Delivery certified, power factor correction, noise filtration,etc. the list goes on...

What we want is optimal performance of all connected electronics! No story-selling!
