In this guide, we will explore common reasons why dishwasher lights may flash and provide troubleshooting steps to help you identify and potentially resolve the problem.
Common Causes of Flashing Lights on a Dishwasher
- Error Codes: Many modern dishwashers are equipped with error code systems that use flashing lights to communicate specific issues, such as water supply problems, drainage issues, or malfunctioning sensors.
- Power Interruption: A temporary power interruption or surge can sometimes cause the dishwasher’s control panel to display flashing lights, signaling that it needs to be reset.
- Door Latch Problems: If the dishwasher’s door is not securely latched or is not making proper contact with the door switch, it can trigger flashing lights.
- Water Inlet Issues: Problems with the water inlet valve, water pressure, or water supply hose can lead to flashing lights as the dishwasher struggles to fill properly.
- Blocked or Clogged Components: Obstructions in the drainage system, such as a clogged filter, drain hose, or pump, can result in flashing lights due to improper water drainage.
