If your dishwasher starts but nothing happens (e.g., no filling, washing, or draining), the most likely culprit is a faulty door latch, a tripped power switch or breaker, a stuck float switch, or an active delay/child lock.
The first and one of the most common reasons your dishwasher may have power but refuses to start is a faulty door latch or door switch. Dishwashers are designed to remain inoperative unless the latch is firmly closed.
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).
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.
A blown dishwasher fuse (often called a thermal fuse) generally causes the dishwasher to lose all electrical function.
To perform a hard reset on a dishwasher, cut off its power source. Unplug the unit or flip the corresponding circuit breaker off for at least 1–5 minutes to clear out the control board's memory, then restore power.
If your dishwasher is not working, you may want to consider these potential causes:
An average dishwasher lasts between 10 to 12 years. However, a model's true lifespan can span from 8 to 15 years, depending heavily on the brand, how frequently it is used, and how well it is maintained.
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.
The most frequent reasons for a dishwasher suddenly losing power include door latch issues, power supply problems (such as tripped circuit breakers or faulty outlets), and control panel malfunctions.
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 bad dishwasher control board usually shows symptoms like an unresponsive display, cycles that won't complete or start, erratic behavior (looping), or failure to fill or drain. The most definitive way to confirm it is bad is to inspect the board for burn marks or damage and use a multimeter to verify that power reaches it, but not beyond it.
Dishwasher repair costs range from $175 to $325, with most homeowners paying around $225 for standard repairs. Costs vary based on the type of repair, parts needed, and labor rates. Understanding these factors can help you budget for your dishwasher repair and avoid unexpected expenses.
If your Dishwasher is making a humming sound but is not filling with water, this could be due to the pump motor not running for a week or longer. This can cause the Dishwasher pump seals to dry out and stick. Operating the Dishwasher at least once a week keeps the seals from drying out and sticking.
If your dishwasher starts but nothing happens (e.g., no filling, washing, or draining), the most likely culprit is a faulty door latch, a tripped power switch or breaker, a stuck float switch, or an active delay/child lock.
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.
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 failure is poor drainage or standing water at the bottom of the tub, which is usually caused by a clogged filter, a blocked drain pump, or a kinked drain hose. This prevents the machine from running or cleaning dishes effectively.
You may need to reset your dishwasher if the control lock or sleep mode is activated or if you've selected a delayed wash cycle. Other reasons for resetting a dishwasher are if the door is not completely closed or if the water and power supply have been cut off.
To fix a dishwasher that won't start, perform a hard reset by shutting off the circuit breaker or unplugging the unit for 2 to 5 minutes. Next, check the door latch and ensure the lower rack is fully pushed in. Finally, verify the power supply, making sure the under-sink GFCI outlet or counter switch hasn’t tripped.
The average lifespan of a dishwasher is 9 to 12 years. However, premium brands properly maintained can last up to 15 years, while heavy use or hard water can cause models to break down in 7 to 8 years.
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.

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.
