A dishwasher that won't start can often be remedied with simple solutions. Verifying the setting status of features like control lock or sleep mode, ensuring the door is latched or checking the power and water supply usually solves the problem.
Several factors can contribute to this, including: Power Issues: The dishwasher might not be plugged in, the circuit breaker could have tripped, or there might be a blown fuse. Door Latch: As mentioned earlier, if the door doesn't latch correctly, the dishwasher won't start as a safety measure.
When your dishwasher won't start, begin troubleshooting by looking at the most common causes: lack of power, broken door latch, defective timer switch, and blown thermal fuse. If it's not those things, you may need to replace the motor starter relay or drive motor instead.
If the dishwasher won't start but has power, it could be stuck between cycles. If the start button has been pushed more than once, the dishwasher may revert to a drain cycle. To remedy this, allow the drain cycle to run, let it sit for 60 to 90 seconds, then press the start button once.
You can reset your dishwasher by unplugging it from its power source for one minute and then plugging it back in. If it's hardwired to a power supply or the plug is not easy to access, turn off the breaker for the dishwasher on your home's electrical panel and turn it back on after one minute.
Some models require powering down the dishwasher by unplugging it or switching off the circuit breaker. Others require pressing and holding the “Start/Reset” button on the control panel, followed by a brief pause before activating a wash cycle.
You may need to press in firmly on the dishwasher door so it latches properly and the cycle starts. Some dishwashers have a control lock or child lock feature that will prevent a cycle from starting and cause the control panel lights to flash.
Check the dishwasher's circuit breaker on your home's circuit panel. If the circuit is tripped, reset it to ensure the dishwasher has power. Check the door latch to see if food particles or grime are blocking it open, preventing the unit from starting.
The most common problem with a dishwasher is a lack of water flow or a clogged drain. This can be caused by blockages in the line, a faulty water inlet valve, or a broken pump motor.
The usual culprits are misalignment of the machine, a latch dirty with food, soap, and grime, a dishwasher rack sticking out, a micro switch in the latch is faulty, problems with the mechanical hinges or springs on the door, or the gasket seal is failing. Check each of these components.
If you're hearing a clicking noise but your dishwasher is not washing, it could be an issue with the home's circuit breakers and fuses. Check the wiring in your home to ensure that all connections are secure and that the circuit breaker or fuse for your dishwasher is properly powered.
Average Lifespan of Dishwashers
According to reputed appliance repair technicians and manufacturers, the average home dishwasher lasts between 10 to 15 years with regular use and proper maintenance. Even an appliance from the best dishwasher brands will only last 15 to 20 years at most.
If your dishwasher isn't starting, it could be that the dishwasher's control keys are locked, the dishwasher could be in demo mode or the door switch isn't working as it should.
Lack of Water Supply
Your dishwasher needs a healthy supply of water to operate correctly. It gets this water through the water inlet valve; if the valve is defective, damaged, or broken, it will disrupt your dishwasher's cycle. Check your home's water pressure to ensure it is normal.
Most dishwashers have a Start button that doubles as the reset button. You can also reference your dishwasher owner's manual to determine the exact location of the reset feature.
Beeping Sound, Blinking or Will Not Start
This light will blink for 75 to 90 seconds, depending on the model. Other blinking lights or beeping sounds: These may indicate a problem with the dishwasher caused by power surges. Try pressing the "Start/Reset" pad to reset the dishwasher and wait 2 minutes.
Bosch, ASKO, GE, Maytag, Whirlpool, and KitchenAid stand out as reputable choices known for their commitment to quality and performance. With a focus on innovation and customer satisfaction, these brands consistently deliver reliable dishwashers equipped with advanced features and durable construction.
Sometimes, the control power is getting power but faulty internal wiring or a failed control panel prevents the dishwasher from working. A service technician typically needs to check and repair the control panel when the dishwasher is getting power but the controls won't light up.
Some dishwashers come equipped with a reset button on the control panel. If your model has one, locate the button and press it. Hold the button for a few seconds until you see lights blink or hear a beep. This action should initiate the reset process.
