Have a powered sub in my computer room that you can hear a "pop" through when the washer or dryer goes through cycles etc...the laundry room is right next to me...so, what will help?
Follow Ups:
Turn the sub off when doing laundry.
Used a soldering iron very very long ago in high school and would not do it now due to peripheral neuropathy in fingers...
check online (ebay) for isolation transformer. A lot of them are plug + play. Topaz is a good brand name.

I've tried many line conditioners, they all change the sound of the stereo, but also add warts that I would rather be without. The popping may or may not be fixed you have to try it in your situation if you want to experiment, but conditioners are not for me.
I've had good luck removing pops from lights and appliances using an isolation transformer. Depending on the draw of the sub, it may have to be a large one but isolating the equipment from the rest of the noise in the circuit is a good idea.

I would work on the washer dryer instead of the stereo.
They are probably 220V so not as easy to fix, but still manageable.
Check some fix it pages for solutions.
I would start with a EMF choke wrapped around the offending appliance cord. One of those spiral wrap types used on some audio powercords.
Or getting an extension cord for it, and wrapping the extension multiple times around a thick heavy steel/iron object.
Second note,
I see that you are in Seattle and very much on the "grid". This is important because you are sharing your power w/ a huge population.
Apartment or single dwelling home?
Are you sure the problem isn't in the power supply of your sub? Has the problem always been present or is it something recent? If recent, you may want to look at the sub amp first. I had a very similar issue in the past that I blamed on my power conditioner, but turned out to be bad caps in the power supply to my preamp.
I have a PS Audio Quintessence, and hear a pop through my speakers when I turned the ceiling fan in my listening room off.
I had a dedicated line installed (not because of the popping) and still hear the pop when I turn the fan off, both with and without the Quintessence. I posted about it, and was told that a dedicated line didn't necessarily cure things like that.
I'd be wary of a "Yes, definitely" answer regarding power conditioners. I'd say it's more of a "You'll have to try it and see" situation, as with most things in this hobby.
Good luck.

You should be able to fix it at source with a powerline filter which usually contains three filter capacitors, plus possibly a choke.
Yes, I had similar problems and the cheapest Furman (AC-215A) i got made a huge difference, not only by stopping all clicks and pops but also bettered the sound of the system.
