Potential Damage: Extremely hot water can damage delicate dishes or plastic items. On the other hand, very cold water can cause thermal shock, leading to cracks or breakage in glassware.
Sanitization Concerns: To ensure proper sanitization, your dishwasher requires water at a certain temperature. Improper water temperature may compromise the effectiveness of the sanitization process, compromising your family's safety.
By understanding the reasons for the start light blinking and the impact of improper water temperature, you can take the necessary steps to resolve the issue and ensure proper functioning of your Whirlpool dishwasher.
Testing The Heating Element
If the start light on your Whirlpool dishwasher is blinking, it may indicate a problem with the heating element. Use a multimeter to test the heating element for continuity and determine if it needs to be replaced. This simple troubleshooting step can help you fix the issue and get your dishwasher running smoothly again.
Using A Multimeter To Check The Heating Element For Continuity
To troubleshoot the issue of the Whirlpool dishwasher start light blinking, one potential cause could be a faulty heating element. The heating element is responsible for heating up the water to the proper temperature during the dishwasher's cycle. If the water doesn't reach the desired temperature within a set amount of time, it can trigger the start light to blink.
To check if the heating element is functioning correctly, you can use a multimeter to test it for continuity. This will determine if there is a break in the electrical circuit, indicating a burnt-out or damaged heating element.
Step-by-step Guide For Testing The Heating Element
Start by turning off the Whirlpool dishwasher and unplugging it from the power source to ensure your safety throughout the testing process.
Locate the heating element, which is typically located at the bottom of the dishwasher and may have two terminals connected to it.
Using a multimeter set to the continuity or ohms setting, touch one probe to each terminal of the heating element.
If the multimeter displays a reading close to zero or beeps, it indicates that the heating element has continuity, meaning it is functioning properly.
However, if the multimeter does not display any reading or remains at infinity, it suggests that the heating element does not have continuity, indicating a fault in the element.
If the heating element fails the continuity test, it will need to be replaced to resolve the issue of the start light blinking.
By following this step-by-step guide and using a multimeter to check the heating element for continuity, you can identify if a faulty heating element is causing the Whirlpool dishwasher start light to blink. If the heating element is indeed damaged, replacing it should resolve the issue and restore the proper functioning of your dishwasher.
When testing terminals, always handle probes by the insulated grips. Basic electrical safety practices from the Occupational Safety and Health Administration are worth reviewing if you are new to using a multimeter. For a broader look at how continuity testing is applied in other gadgets, the same continuity testing methodology is used for troubleshooting a dyson vacuum's blinking light indicator.
Resetting The Blinking Light
To reset the blinking light on a Whirlpool dishwasher, first check if the water is reaching the proper temperature. If not, the heating element may need to be tested for continuity using a multimeter. Another option is to turn off the dishwasher, fully open the door, close it again, and turn it back on.
If the start light continues to blink, it may indicate a short or stuck button on the touch control panel.

Remember to always prioritize your safety by disconnecting the power supply before attempting any repairs and consult a professional if needed.
Decoding Whirlpool Dishwasher Error Codes
Depending on your Whirlpool model, the blinking start light may follow a specific pattern (e.g., 3 flashes, 4 flashes, 5 flashes). These flash patterns are diagnostic codes that can pinpoint the issue without needing a multimeter.
3 Flashes: Heating element failure or high-limit thermostat open. 4 Flashes: Water temperature sensor (thermistor) fault. 5 Flashes: Control board / keypad communication error. 6 Flashes: Water inlet or drain timeout. 7 Flashes: Heating element relay stuck. 8 Flashes: Door latch / micro switch failure.
If your start light is blinking in a pattern, count the flashes carefully. This can save hours of guesswork. Note that older Whirlpool models may use a different numbering system; checking your specific manual is always best. For the most up-to-date information, refer to Whirlpool's official portal. Just as refrigerator fault codes can display a specific error on a separate panel, Whirlpool's integrated system uses the start light exclusively.
Inspecting the Door Latch and Micro Switch
One frequently overlooked cause of a blinking start light is a faulty door latch assembly. The dishwasher won't proceed with its cycle if the control board doesn't register that the door is fully closed. Over time, the plastic latch can wear down or the internal micro switch can fail.
How to test: With the dishwasher powered on, press the door firmly shut. If the start light stops blinking or the sound changes, the latch may be loose. You can test the micro switch with a multimeter for continuity when the door is closed. If the switch fails to close the circuit, it must be replaced. Unlike testing the heating element, the door latch issue often prevents the motor from running altogether.
If you have ruled out the heating element, thermostat, and door latch, the problem likely lies in the control board itself. Much like a thermostat that blinks red to signal a low battery or wiring fault, the dishwasher's flashing light indicates a need for board replacement.
Detergent and Over-Sudsing Issues
Using hand dish soap or excessive detergent in a Whirlpool dishwasher can create a massive overflow of suds. This triggers the dishwasher's flood prevention lockout, causing the start light to blink frantically and the pump to run continuously without starting a cycle.
What to do: If you suspect over-sudsing, immediately stop the cycle, open the door, and scoop out as many suds as possible. Sprinkle salt or pour a cup of white vinegar into the bottom of the unit to kill the remaining suds. Run a rinse cycle without detergent. Never use hand dishwashing liquid in an automatic dishwasher, as it is specifically formulated for high-suds environments.
When to Call a Professional Repair Technician
While many causes of a blinking start light are DIY-friendly, some issues require professional service. You should call a technician if:
- The control board shows signs of burning or physical damage.
- You have tested the heating element, thermostat, and door latch, but the error persists.
- The integrated error code points to a control board failure (5 or 7 flashes), as board replacement often requires firmware pairing unavailable to consumers.
- There is a visible short or spark when plugging the unit in.
Attempting complex repairs on a dishwasher's main control board without proper training can lead to further damage or electrical shock.
