If your dishwasher isn't working, the fastest way to get it running again is to check for a tripped circuit breaker, ensure the door is firmly latched, and verify that the water supply valve under your sink is completely turned on.
The most common dishwasher fault is clogged or poor drainage. This occurs when food debris, grease, or foreign objects (like broken glass or food particles) block the primary drain filter, the drain hose, or the garbage disposal connection, leaving dirty, standing water at the bottom of the unit.
Most dishwashers do not have a dedicated, standalone "Reset" button. Instead, you can usually reset the appliance by pressing and holding the Start/Reset or Cancel/Drain button for 3 to 5 seconds, or by performing a power cycle (shutting off the power).
Your dishwasher might be receiving power, yet the control board or timer could be malfunctioning and not sending commands properly. While timers are designed to last, they can wear out over time. Listen closely for unusual buzzing noises or irregular clicking, as these could hint at a malfunctioning timer.
Common Causes for a Dishwasher Not Starting
Check for Power: Confirm the power supply and circuit breaker status. Ensure the dishwasher is plugged in and receiving power. For hardwired units, check the circuit breaker to see if it has tripped. Resetting a tripped breaker might solve the problem.
To hard reset a dishwasher, cut off its power to clear the control board's memory. Unplug the unit or turn off the dedicated circuit breaker in your home's electrical panel. Wait at least 1 to 5 minutes before restoring power, then select your cycle and press Start.
The average dishwasher lasts 9 to 12 years. With meticulous maintenance and light usage, some high-end or European models (like Bosch) can stretch up to 15 years, while cheaper models or those run daily may wear out in 7 to 9 years.
Your dishwasher is likely failing if you notice pooled water at the end of a cycle, persistent burning smells, or dishes consistently coming out dirty or cold. These issues often point to failing motors, faulty heating elements, or blocked pumps.
A blown dishwasher fuse (often called a thermal fuse) generally causes the dishwasher to lose all electrical function.
Dishwashers usually don't have a dedicated reset button on the control panel. You can reset your dishwasher by unplugging it from its power source for one minute and then plugging it back in.
If your dishwasher is not working, you may want to consider these potential causes:
A bad dishwasher control board usually shows symptoms like completely unresponsive buttons, erratic cycle behavior (e.g., getting stuck in a loop or stopping mid-cycle), frequent and unexplained error codes, or the dishwasher failing to start at all.
Most dishwashers do not have a dedicated, standalone "Reset" button. Instead, you can usually reset the appliance by pressing and holding the Start/Reset or Cancel/Drain button for 3 to 5 seconds, or by performing a power cycle (shutting off the power).
You can repair minor dishwasher problems yourself, such as loose door latches, clogs, or dirty spray arms. More complicated dishwasher repairs are best left to professional plumbers.
A dishwasher that has power but won't turn on often indicates an issue with a safety switch, a stuck cycle, or a failed control component. The most effective troubleshooting steps can be taken in the following order:
Common Signs It's Time To Buy a New Dishwasher
The control board or electronic control unit is typically the most expensive part in a dishwasher. It manages all the dishwasher's functions, such as the wash cycles, water temperature, and the timing of the washing and drying processes.
Yes, a 5-year-old dishwasher is usually worth repairing. The average lifespan of a dishwasher is 8 to 12 years, and a 5-year-old unit is generally past its initial manufacturer warranty but still has plenty of life left to justify the cost of minor fixes.
Expert Picks: The Most Reliable Dishwasher Models. The average cost to replace a dishwasher will depend on the model you choose. You can expect to pay between $300 and $1500 for a new appliance.
The most common dishwasher fault is clogged or poor drainage. This occurs when food debris, grease, or foreign objects (like broken glass or food particles) block the primary drain filter, the drain hose, or the garbage disposal connection, leaving dirty, standing water at the bottom of the unit.
Some models require you to shut off the power to the dishwasher either by unplugging it or shutting off the circuit breaker. Others are reset by pressing and holding the Start/Reset button on the control panel, then waiting a few moments before attempting to start a wash cycle.
Turn Off and Unplug the Dishwasher
Before attempting any reset, safety should be your primary concern. Dishwashers are electrical equipment and require caution. Locate the dishwasher plug and disconnect it from its outlet.
