Whirlpool Dishwasher Not Starting: Power and Door Fixes
Quick Answer
Whirlpool Dishwasher not starting: check that the door or lid is fully closed first, then verify the breaker is on and child lock is not enabled. Try a power reset (unplug 2 minutes). If still dead, test the door switch and thermal fuse with a multimeter.
Most of the time when I get this call, it turns out to be the control lock or a door that's not quite latched right. But sometimes it's a blown thermal fuse after a power surge, and that's when it gets more involved. Ignore this too long and you might convince yourself the control board is dead when it's actually a $12 fuse. Let's figure out which one you've got.

Whirlpool Dishwasher Not Starting: Power and Door Fixes
So your Whirlpool dishwasher is sitting there mocking you, completely ignoring the Start button. I see this a lot. Honestly, nine times out of ten it's something like the control lock got accidentally triggered while someone wiped down the panel, or the door didn't quite click all the way. The other times it's a tripped breaker or a thermal fuse that gave up after a surge. Either way, you can probably fix this yourself in under an hour.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Door not fully latched - latch requires a firm push40%
Control lock engaged preventing button input24%
Delay Start is set - dishwasher is waiting for its timer14%
Start button held too briefly (requires 3-second press on some models)12%
No power to the unit (tripped breaker or failed outlet)10%
Symptoms You May Notice
You press Start and absolutely nothing happens. No hum, no water trickling, no sounds whatsoever.
The control panel lights up fine and shows the cycle options, but pressing any button including Start does nothing at all.
There's a small padlock icon or the letters LOC showing somewhere on the display.
The whole panel is completely dark, no lights, no display, like the unit has zero power.
The display is showing a countdown timer ticking down and you never set it that way.
Can you reset a Whirlpool dishwasher to clear the NOT-STARTING code?
Hold the Cancel or Drain button for three full seconds until the pump kicks on briefly or the display clears. Let it drain completely, then wait 60 seconds before touching anything. If the panel is completely dark and frozen, flip the breaker off for a full minute, then back on. Give it another 30 seconds after power comes back before you press anything. This clears most software glitches that make the control board ignore the Start command entirely.

Diagnostic Checklist
Follow these steps in order. We start with the easiest external fixes before opening up the machine.
Did the fix not work?
If the problem comes back after following these steps, a component has permanently failed and needs replacement. Check the specific error code your dishwasher is showing:
ConditionIf Open (OL) or infinite, replace component.
Replacement Parts
If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions
My Whirlpool dishwasher beeps when I press Start but doesn't run. What does that mean?
That beep means the control board heard you, but the door switch is telling it the door is still open. Even if the door looks completely shut, the microswitch inside the latch might not be making full contact. Check that the top rack is pushed all the way back and nothing's hanging over the door opening. If the latch clicks but it still beeps, that microswitch inside the latch assembly is probably failing. You can confirm it with a multimeter continuity test. Latch assemblies run about $25 to $45 and take maybe 20 minutes to swap out. Not a hard repair at all.
How long do I hold the Start button on a Whirlpool dishwasher?
Three full seconds, and really commit to it. Don't just tap it. A lot of people barely graze it and then wonder why nothing's happening. Press it firmly and hold until you hear the drain pump kick on or the Sensing or Washing light comes on. This is intentional design, it's a safety feature so the machine doesn't accidentally start. If you've held it a solid three seconds and still nothing, that's when you start working through the other causes in this guide.
Can a power outage cause my Whirlpool dishwasher to not start at all?
Yeah, definitely. Power surges and outages mess with the control module pretty regularly. What usually happens is the board gets stuck in a weird state mid-cycle and then won't respond to Start after power comes back. Sometimes it's worse and a surge actually blows the thermal fuse, which cuts all power to the panel completely. First thing to try after any outage is a hard reset at the breaker, off for a full minute then back on. If the panel stays completely dark after that, you're probably looking at a blown thermal fuse. Quick $10 fix if that's it.
How do I know if the thermal fuse is blown on my Whirlpool dishwasher?
Biggest tell is a completely dark panel. No lights, no display, not even a clock or a single indicator light. Nothing at all. That's almost always a blown thermal fuse or a dead control board, and the fuse is way more likely and way cheaper to check first. You'll need to pull the inner door panel to get to it, then test it with a multimeter on continuity. If it reads open, you found your problem. Part is usually under $15. Common part number for WDT and WDF series is W10258275 but double-check it against your specific model number before ordering.
My dishwasher shows a timer counting down and won't start. What's going on?
Delay Start is active. It's literally just waiting for that timer to hit zero before it'll do anything. Press and hold Cancel for three seconds to clear it, then set your cycle and hit Start normally. Happens all the time. That Delay Start button is right next to everything else and it's easy to bump accidentally while you're selecting a cycle.
Is it worth repairing a Whirlpool dishwasher that won't start, or should I just replace it?
Depends entirely on what's broken. Door latch is $25 to $45, thermal fuse is $8 to $15, control lock issue costs nothing. All worth fixing without question. If the control board itself is dead, those run $150 to $300 for the part alone, and at that point you're getting close to the cost of a new entry-level unit. For any dishwasher under five years old, almost always worth repairing. Over ten years and you're staring at a board replacement, I'd start pricing out replacements at the same time so you can make an informed call instead of just throwing money at an old machine.
