Question: Why do the lights dim momentarily when the dishwasher or washing machine changes cycles or turns on? Is this a cause for concern?
Answer: It’s normal to notice slight dimming or flickering of lights when large appliances like dishwashers or washing machines turn on or change cycles. This happens because motors in these appliances draw more electrical current during start-up than when they are running at a steady speed. As long as the dimming is brief and only occurs when the appliance starts, there is generally no cause for concern.
