Checking Power and Connections

Ensure the dishwasher is properly plugged in

One common issue that homeowners may encounter with their dishwasher is a lack of power. It’s important to check if the dishwasher is properly plugged into an electrical outlet. Sometimes, due to movements or accidents, the plug may become loose or disconnected.
