When your dishwasher has power but won't start, the most common culprits are an unlatched door, an active child lock, or a stuck cycle.
If your dishwasher has power (lights are on) but won't start, the most common culprits are an unlatched door, an activated child lock, or a tripped delay timer. Clear, actionable troubleshooting steps can help you pinpoint the issue quickly:
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).
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.
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.
A blown dishwasher fuse (often called a thermal fuse) generally causes the dishwasher to lose all electrical function.
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.
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.
Mr. Appliance offers these expert tips for fixing a dishwasher that isn't cleaning dishes properly.
How do I know if my dishwasher's control board is faulty? Look for symptoms like unresponsive buttons, erratic cycle behavior, frequent error codes, or the dishwasher failing to start or complete cycles. These often indicate control board issues.
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.
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.

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.
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.
To know if a fuse is blown, inspect the filament inside the fuse. If the wire is severed, melted, or if the inside of the fuse looks dark or cloudy, the fuse is blown. You can also test it without removing it using a multimeter or a test light.
Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses.
