If the start button on your Whirlpool dishwasher isn't working, there could be several reasons behind it. Firstly, ensure the appliance has power by checking the plug socket, circuit breaker, and fuse. Another potential issue is the door not closing correctly due to obstruction, child lock activation, or a faulty latch or sensor. Insufficient water supply, caused by a twisted inlet hose or faulty inlet valve, can also prevent the dishwasher from starting.
In some cases, the thermal fuse might have blown due to overheating, requiring replacement. Occasionally, a stuck key on the control panel can interfere with the dishwasher's operation, necessitating a thorough cleaning or even a new electronic control board. If all else fails, resetting the dishwasher by holding the "Start" button for a few seconds or unplugging it for 15 minutes might resolve the issue.
