Why Your Dishwasher Is Flashing And How To Fix It Fast

A flashing dishwasher light can be a frustrating and confusing problem. Understanding the reasons behind these flashing lights is crucial for resolving the issue and getting your dishwasher back in working order. This comprehensive guide will delve into the common causes of flashing dishwasher lights and provide step-by-step instructions on how to diagnose and fix the problem.

Common Causes of Flashing Dishwasher Lights

1. Faulty Door Latch: A malfunctioning door latch can prevent the dishwasher from starting or cause it to stop mid-cycle.
2. Control Panel Issues: Electrical problems or software glitches within the control panel can trigger flashing lights.
3. Overflow Switch Activation: If the dishwasher fills with too much water, the overflow switch will activate, causing the dishwasher to stop and flash lights.
4. Drain Pump Failure: A faulty drain pump can prevent the dishwasher from draining properly, resulting in flashing lights.
5. Heating Element Problems: Issues with the heating element can cause the dishwasher to stop heating water, leading to flashing lights.
6. Water Inlet Valve Malfunction: A malfunctioning water inlet valve can prevent the dishwasher from filling with water, triggering flashing lights.
7. Flooding: In some cases, a dishwasher may flash lights due to flooding or water leakage.

Troubleshooting Flashing Dishwasher Lights

1. Check the Door Latch

• Ensure the dishwasher door is properly closed and latched.
• Inspect the door latch for any damage or misalignment.
• If the latch appears damaged, replace it.

2. Reset the Control Panel

• Unplug the dishwasher from the power outlet.
• Wait 60 seconds.
• Plug the dishwasher back in.
• Check if the flashing lights have disappeared.

3. Inspect the Overflow Switch

• Locate the overflow switch, which is usually found at the bottom of the dishwasher.
• Check if the switch is activated (it will be in the “up” position).
• If the switch is activated, drain the excess water from the dishwasher.

4. Test the Drain Pump

• Unplug the dishwasher from the power outlet.
• Disconnect the drain hose from the dishwasher.
• Blow air into the drain hose. If air flows freely, the drain pump is functioning properly.
• If air does not flow, the drain pump may be clogged or faulty.

5. Inspect the Heating Element

• Unplug the dishwasher from the power outlet.
• Remove the bottom panel of the dishwasher.
• Locate the heating element and visually inspect it for any damage or corrosion.
• If the heating element appears damaged, replace it.

6. Check the Water Inlet Valve

• Unplug the dishwasher from the power outlet.
• Turn off the water supply to the dishwasher.
• Disconnect the water inlet hose from the dishwasher.
• Check if water flows freely from the hose. If water does not flow, the water inlet valve may be faulty.

7. Inspect for Flooding

• Check the floor around the dishwasher for any signs of water leakage.
• If there is water on the floor, unplug the dishwasher and call a plumber.
