Understanding the Blinking Codes
Before we dive into the troubleshooting process, it’s essential to understand the language of your Whirlpool dishwasher’s blinking codes. These codes are designed to communicate specific error messages, helping you identify the problem and take corrective action.
The most common blinking patterns on Whirlpool dishwashers include:

What is the blinking error code on my Whirlpool dishwasher?
The blinking error code on your Whirlpool dishwasher is a series of flashing lights that indicate a specific problem with the appliance. These codes are designed to help you diagnose and troubleshoot issues with your dishwasher, so you can take the necessary steps to get it up and running again.
The error code will typically appear on the display panel of your dishwasher, and it may be accompanied by a beeping noise or other indicators. By consulting your user manual or searching online, you can determine what the specific code means and what steps you need to take to resolve the issue.
Why is my Whirlpool dishwasher blinking and not turning on?
If your Whirlpool dishwasher is blinking but not turning on, it’s likely that there is a fault with the appliance’s power cycle. This could be due to a faulty control board, a broken door latch, or a problem with the dishwasher’s wiring.
To troubleshoot the issue, try unplugging the dishwasher from the power outlet and waiting for 30 seconds before plugging it back in. This can sometimes reset the appliance and get it working again. If this doesn’t work, you may need to check the door latch and wiring for any signs of damage or wear. If you’re still having trouble, it may be best to contact a professional appliance repair technician.
How do I reset my Whirlpool dishwasher?
Resetting your Whirlpool dishwasher can sometimes resolve issues with the appliance, including problems with blinking lights or failure to turn on. To reset your dishwasher, unplug it from the power outlet and wait for 30 seconds.
Plug the dishwasher back in and check to see if it’s working properly. If you’re still experiencing issues, you may need to consult your user manual for more detailed reset instructions or contact a professional appliance repair technician for further assistance.
What does it mean if my Whirlpool dishwasher is blinking 7 times?
If your Whirlpool dishwasher is blinking 7 times, it’s likely that there is a issue with the appliance’s heating element or thermistor. The thermistor is responsible for regulating the dishwasher’s temperature, and if it’s faulty, it can cause problems with the appliance’s wash cycle.
To resolve the issue, you may need to check the thermistor for signs of damage or wear. If it’s faulty, you may need to replace it with a new one. You can consult your user manual for more information on how to do this, or contact a professional appliance repair technician for further assistance.
Can I repair my Whirlpool dishwasher myself?
While it’s possible to repair your Whirlpool dishwasher yourself, it’s not always recommended. If you’re not familiar with appliance repair, you could end up causing further damage to the dishwasher or injuring yourself.
However, if you’re comfortable with DIY repairs, you can try troubleshooting the issue and checking the user manual for guidance. You can also find online tutorials and repair guides that can walk you through the process step-by-step.
How much does it cost to repair a Whirlpool dishwasher?
The cost of repairing a Whirlpool dishwasher can vary depending on the nature of the problem and the cost of replacement parts. If you’re hiring a professional appliance repair technician, you can expect to pay anywhere from $50 to $200 for the service call, plus the cost of any replacement parts.
If you’re repairing the dishwasher yourself, you’ll only need to pay for the cost of replacement parts, which can range from $20 to $100 or more, depending on what’s needed.
Should I replace my Whirlpool dishwasher if it’s still under warranty?
If your Whirlpool dishwasher is still under warranty, it’s usually best to contact the manufacturer or a authorized service provider for assistance. They can send a technician to repair or replace the appliance free of charge, depending on the terms of the warranty.
However, if the warranty has expired, it may be worth considering replacing the dishwasher altogether, especially if it’s an older model or has been experiencing frequent problems. A new dishwasher can provide better performance and energy efficiency, and may be more cost-effective in the long run.
