Why do all the lights flicker when the washing machine and dryer is on?

The flickering lights when the washing machine and dryer are running may be due to a surge in electrical demand. Both appliances draw significant power, especially during their heating cycles, which can cause a temporary drop in voltage and result in flickering lights. Additionally, if the wiring in your home is outdated or inadequate for the load, it can exacerbate the issue. Consider consulting an electrician to assess your electrical system for safety and capacity.
