Whirlpool Dishwasher Not Turning On

A dishwasher is a modern convenience that saves time and effort in the kitchen. However, when your Whirlpool dishwasher refuses to turn on, it can be frustrating. Before calling for professional help, you can perform some troubleshooting steps to identify and potentially resolve the issue. This guide will walk you through the process step by step.

1. Check Power Supply:

  • Ensure the dishwasher is plugged into a functioning power outlet. Check the power cord and make sure it’s securely connected.
  • Verify that there are no tripped circuit breakers or blown fuses in your home’s electrical panel. Reset any tripped breakers and replace blown fuses as needed.

2. Door Latch Inspection:

  • The dishwasher will not start if the door is not securely closed. Inspect the door latch to ensure it’s engaging properly.
  • Clean the latch and the area around it from any debris or obstructions that might be preventing it from closing properly.

3. Control Lock Feature:

  • Many Whirlpool dishwashers have a control lock feature that can accidentally be activated, preventing the dishwasher from starting. Look for a “Control Lock” or “Child Lock” button on the control panel.
  • To deactivate the control lock, press and hold the button for several seconds until you hear a beep or see the indicator light turn off.

4. Timer Delay Setting:

  • Check if you have inadvertently set a timer delay on your dishwasher. If a delay is set, the dishwasher will not start until the specified time has passed.
  • To cancel the delay, refer to your dishwasher’s user manual for specific instructions, as the process may vary by model.

5. Water Supply Check:

  • Ensure that the water supply to the dishwasher is turned on and that there are no kinks or obstructions in the water inlet hose.
  • Inspect the water inlet valve for any clogs or damage, which can prevent water from entering the dishwasher.

6. Overloaded Dishwasher:

  • Overloading the dishwasher can prevent it from starting. Make sure that dishes are arranged properly and not blocking the spray arms or detergent dispenser.

7. Faulty Door Switch:

  • The dishwasher’s door switch plays a crucial role in enabling it to start. If the switch is faulty, the dishwasher may not turn on.
  • Test the door switch for continuity using a multimeter. If it doesn’t register continuity when the door is closed, the switch may need to be replaced.

8. Control Panel Issues:

  • If none of the above steps resolve the issue, there may be a problem with the control panel or the electronic control board.
  • Contact Whirlpool customer service or a certified technician to diagnose and repair control panel or board issues.

9. Check for Water Leaks:

  • Dishwashers are equipped with a float switch that prevents them from starting if there’s water in the base due to a leak. Look for any signs of water under or around the dishwasher.
  • If you find water, locate and fix the source of the leak before attempting to use the dishwasher again. Common sources of leaks include a damaged door seal, loose hose connections, or a cracked tub.

10. Inspect the Control Panel Display:

  • If your dishwasher has a digital display, inspect it for error codes or messages. These codes can provide valuable information about the issue.
  • Refer to your dishwasher’s user manual for a list of error codes and their meanings. This can help pinpoint the specific problem.

11. Test the Power Outlet:

  • Sometimes, the power outlet itself may be faulty. Plug another working appliance into the same outlet to verify that it’s providing power.
  • If the outlet isn’t working, you may need to consult an electrician to repair or replace it.

12. Reset the Dishwasher:

  • Some dishwasher models have a reset function that can help clear minor electronic glitches. To reset your dishwasher:
    • Unplug it from the power source or turn off the circuit breaker for a few minutes.
    • Plug it back in or turn the circuit breaker back on.
    • Try starting the dishwasher again.

13. Examine the Thermal Fuse:

  • The thermal fuse is a safety device that can cut off power to the dishwasher if it overheats. If it’s blown, the dishwasher won’t start.
  • Access the thermal fuse, usually located on or near the control board, and test it for continuity using a multimeter. If it’s open (no continuity), replace it with a compatible fuse.

14. Call Whirlpool Customer Support:

  • If you’ve exhausted all troubleshooting steps and the dishwasher still won’t turn on, it’s time to contact Whirlpool’s customer support or visit their website for further guidance.
  • They can provide specific advice for your dishwasher model and may arrange for a service technician if necessary.

15. Warranty Consideration:

  • If your Whirlpool dishwasher is still under warranty, be sure to check the terms and conditions. Attempting to fix the dishwasher yourself or using unauthorized service can void the warranty. In such cases, it’s best to rely on Whirlpool’s authorized service technicians.
