Obviously, visible flicker is the one that we can see with our eyes. This occurs when the light output from a given source changes rapidly. It is considered that anything below a frequency of Hz can be seen.
They go on to explain that there are health problems that can be caused by this flicker. Short-term exposure to frequencies in the 3Hz to 70Hz range are associated with epileptic seizures. Invisible flicker is one that is present that we cannot see. It is just as much of a problem as visible flicker, maybe even worse. Even though we cannot see it, you can experience symptoms such as dizziness, eyestrain, headaches, migraines, impaired thought, and other general sick-feeling symptoms.
The wiring in your home has an electrical current and the resistance of each wire uses some of the voltage when things in your household are turned on and off.

I have the exact same issue but performed a few different troubleshooting steps that were not mentioned here. To begin, this is a rental home built in All aluminum wiring with some copper for lighting overhead that was updated in They both plug into 1 receptacle with the a top and bottom outlet.
This is wired back to the breaker box as 2 20 amp circuits. They share a neutral wire. The circuit breakers were old and not joined with any bar that physically connected the two switches into one so that one off makes both off.
The receptacle was old, loose and burnt up some. And even more concerning, the tab on the line right side was not broken to properly separate the top and bottom circuits.
I assume that someone replaced this laundry receptacle at least once in the distant past and forgot to break the right tab. I replaced the receptacle with a new 20 amp outlet and broke the tab on the right side only. It is also grounded of course.
I also replaced the two circuit breakers in the box with new and specifically for this type of setup. It has the bar that physically joins the switches for off and on. I also checked and tightened all neutrals in the panel. But even after all that, the damn dimming still occurs when agitating. I should add that all my lighting is LED too. Here is the last important clue that I would think others could try too. I was doing some laundry and it had just started to agitate and dim like always.
Anyways, the washing machine worked fine and there was no dimming throughout the entire cycle. I left it like that for a few days and it continued to perform without dimming the lights. Additionally, this dimming would occur whether the dryer was also being used or when it was off. Keep in mind that they share one neutral.
I tested both the top and bottom outlets and the readings all indicate a grounded correct setup. There is no open neutral.
Perhaps i also need power company to come out like person above had when their issue was resolved. We were having the dimming issue most noticeable when the washer was agitating. Even plugged into a different circuit and found the same thing.
Called out our power company, turns out the neutral was faulty coming from the transformer to the house. Fixed in 10 minutes, no hint of dimming now.
