No lights at all
The panel stays dark, no response from any button, and no sound when you try to start a cycle.
Start here: Go straight to the house power, outlet, and under-sink connection checks.
Direct answer: When a Whirlpool dishwasher will not start, the usual causes are lost power, a tripped control lock, a door that is not latching cleanly, or a stuck user interface. Start there before thinking about internal parts.
Most likely: Most often, this turns out to be a simple power issue, a half-latched door, or controls that need a reset after a glitch.
First separate what the machine is doing. If it is completely dead, stay on the power path. If lights come on but nothing happens when you press Start, focus on control lock, cycle selection, and the door latch. Reality check: a dishwasher that looks dead can still be getting partial power. Common wrong move: slamming the door harder instead of checking whether the latch is actually catching and the controls are unlocked.
Don’t start with: Do not start by ordering a control board. On this symptom, boards get blamed a lot more often than they actually fail.
The panel stays dark, no response from any button, and no sound when you try to start a cycle.
Start here: Go straight to the house power, outlet, and under-sink connection checks.
The display responds, but the cycle will not begin or it just sits there after you press Start.
Start here: Check for control lock, cancel the current selection, then test the door latch.
The dishwasher chirps, flashes, or acts like it wants to start, but the wash cycle never begins.
Start here: Treat that like a door-latch or control-state problem before assuming a failed part.
It may run after several tries, after opening and closing the door, or after flipping the breaker.
Start here: Look for a loose power connection, weak door latch engagement, or a failing touchpad response.
A dead panel with no lights is usually a supply problem before it is a dishwasher part problem.
Quick check: Plug in a small lamp or tester at the dishwasher outlet if accessible, and check whether the breaker is fully reset.
If the panel lights up but ignores Start, the controls may be locked or the last cycle may not have cleared properly.
Quick check: Look for a lock icon or locked-controls light, then press and hold the marked lock button area for several seconds.
These machines will not start a wash cycle unless the door switch sees a fully latched door.
Quick check: Close the door slowly and listen for a clean click. If you have to lift, push, or slam the door, the latch path needs attention.
If power is good, the door is latching, and the controls still act erratic or partly dead, the control side becomes more likely.
Quick check: Try a full power reset. If some buttons never respond or the panel behaves inconsistently, the interface or control may be failing.
A dishwasher with no lights and no sound is most often dealing with lost power, not a bad internal part.
Next move: If the panel comes back to life after restoring power, run a short cycle and watch for normal fill and wash sounds. If the outlet has power but the dishwasher stays completely dead, move on to a control reset and door check.
What to conclude: You have either ruled out the house power side or found the problem before taking the dishwasher apart.
A locked or confused control panel can make the dishwasher look broken when it is really just refusing a start command.
Next move: If the dishwasher starts after unlocking or resetting, the issue was likely a control state problem rather than a failed component. If lights work but the machine still will not begin, the next likely branch is the door latch or door alignment.
What to conclude: The dishwasher has at least some power and the controls are alive enough to respond, which narrows the problem.
A Whirlpool dishwasher will not start a wash cycle if the latch switch does not see the door fully closed, even when the door looks shut.
Next move: If the dishwasher starts when the door is seated properly, correct the rack loading or minor obstruction and keep using it. If the door closes cleanly but the dishwasher still will not recognize it, the latch assembly becomes a likely repair path.
Once power and latch basics are ruled out, the pattern of button response matters more than guessing at parts.
Next move: If one reset or button sequence brings it back and it runs normally, keep an eye on it but do not rush to replace parts. If the controls are inconsistent or the machine is dead with verified power, you have narrowed it to a latch or control failure path.
At this point you should have a clean direction instead of throwing parts at the dishwasher.
A good result: If the dishwasher now starts consistently without extra pressure on the door, the repair path was correct.
If not: If a confirmed latch issue has been addressed and startup is still erratic, the remaining likely fault is in the user interface or electronic control and it is time for service.
What to conclude: You have moved from broad troubleshooting to the most likely repair without wasting money on the wrong part.

The most common reasons are control lock being on, the previous cycle not being cleared, or the door latch not being recognized as closed. Start by unlocking the controls, pressing Cancel, then trying a fresh cycle with the door shut firmly.
A completely dark panel usually points to lost power first. Check the breaker, the outlet, and the dishwasher plug or connection under the sink before assuming an internal failure.
Yes. If the latch switch does not see the door fully closed, the dishwasher will not begin washing. A strong clue is when it starts only if you push on the door or re-close it several times.
Not as a first move. Control boards are expensive and often blamed too early. Rule out power, control lock, and door latch problems first. If the panel behavior is erratic or partly dead after those checks, then a pro diagnosis makes more sense.
That usually means the controls are alive but the machine is refusing the start command. The door may not be latching cleanly, the controls may be locked, or the cycle may need to be canceled and restarted.
Yes. Try pressing Cancel to clear the cycle, then cut power at the breaker for about 2 minutes and restore it. After power comes back, select a fresh cycle and press Start, then close the door promptly if your model requires that.
