Dacor Dishwasher lights flashing or blinking

Symptoms:

• One or more lights on the dishwasher’s control panel are flashing or blinking continuously.
• The dishwasher may not be functioning properly.
• The display may be malfunctioning.

Possible Causes:

• Micro switch issue: The micro switch located within the door latch assembly may be faulty, causing intermittent contact and triggering the flashing lights.
• Faulty water inlet valve: A malfunctioning water inlet valve can lead to inconsistent water flow, resulting in flashing lights and potential malfunctions.
• Control panel problem: If the control panel buttons are unresponsive or the display is malfunctioning, it could be the culprit behind the flashing lights.
• Sensor error: A faulty sensor, such as the water level sensor or the temperature sensor, can send incorrect signals to the control board, triggering the flashing lights.
• Wiring issue: Loose or damaged wiring connections within the dishwasher can disrupt communication between components and lead to flashing lights.
• Software glitch: In rare cases, a software glitch in the dishwasher’s main control board might cause the flashing lights.

Preliminary Steps:

1. Power cycle the dishwasher: Turn the dishwasher off at the circuit breaker, wait for 30 seconds, then turn it back on. This can sometimes reset the control board and resolve minor glitches.
2. Check the door latch: Ensure the door is closed properly and the latch is engaged. A loose door can trigger the flashing lights.
3. Clean the control panel: Wipe down the control panel buttons with a damp cloth to remove any debris or spills that might be interfering with their functionality.

Advanced Troubleshooting:

1. Test the micro switch: Use a multimeter to check the continuity of the micro switch. If the switch is faulty, it will need to be replaced.
2. Inspect the water inlet valve: Visually examine the valve for any leaks or damage. Check the water flow and pressure using a water pressure gauge. If the valve is malfunctioning, it will need to be replaced.
3. Test the control panel buttons and display: Use the user manual to identify the function of each button and test their responsiveness. If any buttons are not working or the display is malfunctioning, the control panel may need repair or replacement.
4. Check the sensors: Consult the user manual to locate the sensors and perform any recommended maintenance procedures. If a sensor appears damaged or faulty, it will need to be replaced.
5. Examine the wiring: Look for any loose or damaged wires within the dishwasher. If you suspect a wiring issue, it is best to consult a qualified technician for safe and proper repair.
6. Software update: Check with the manufacturer for any available software updates for your dishwasher model. Updating the software may resolve flashing light issues caused by glitches.
