Direct answer: When a dishwasher starts then stops, the most common causes are a door that is not staying latched, a cycle that is pausing during fill or heat, or a drain or float problem that interrupts the wash. Start by confirming whether it truly shuts off or just goes quiet for a few minutes.
Most likely: A loose dishwasher door latch or a cycle interruption from standing water, a clogged filter, or a stuck dishwasher float is more likely than a bad electronic part.
Watch the machine for one full start attempt. Listen for the fill, the first wash sound, and whether the lights stay on or go dead. That pattern tells you a lot faster than guessing. Reality check: many newer dishwashers go quiet for stretches and homeowners think they quit. Common wrong move: canceling and restarting the cycle over and over before checking the filter, float, and door catch.
Don’t start with: Do not start by ordering a control board or tearing into wiring. Most of these calls end up being a latch, blockage, or normal cycle pause.
You hear it start, then it goes quiet, but the display or indicator lights are still on.
Start here: First decide whether it is a normal pause. Wait several minutes, then check for standing water, a clogged filter, or a stuck float.
The dishwasher starts, then the lights go out or the panel becomes unresponsive.
Start here: Check the house power first, then the door latch. A latch that opens electrically or mechanically can kill the cycle fast.
You hear water enter, but the wash never really gets going.
Start here: Look for a stuck dishwasher float, debris in the sump area, or water left in the bottom from a drain restriction.
The dishwasher may start, pause, or resume depending on door pressure.
Start here: Go straight to the dishwasher door latch and strike area. That is the clearest clue on this symptom.
If the control thinks the door opened, the cycle stops immediately or acts dead even though nothing else is wrong.
Quick check: Start a cycle and press gently on the top corners of the door. If the dishwasher resumes, clicks, or changes behavior, the latch area is suspect.
Many dishwashers pause during fill, sensing, soaking, or heating, especially early in the cycle.
Quick check: Let it sit untouched for 5 to 10 minutes. If it resumes on its own and the lights never went out, it may be operating normally.
If the dishwasher cannot clear water properly, some models stall, stop advancing, or cancel the wash portion.
Quick check: Open the door after it stops and look for standing water in the bottom. Check the dishwasher filter and the drain path for food sludge or glass bits.
A float that reads full can stop further filling and leave the machine sitting there without moving into a normal wash.
Quick check: Find the float inside the tub floor area and make sure it moves up and down freely without grit, scale, or a utensil blocking it.
A quiet dishwasher is not always a failed dishwasher. Newer cycles often sit still while filling, soaking, or waiting on temperature.
Next move: If the dishwasher resumes on its own, you were likely catching a normal pause rather than a true shutdown. If it stays dead, never resumes, or repeatedly stops at the same early point, move on to the door and drain checks.
What to conclude: Lights staying on usually points away from a total power loss. A dead panel or a cycle that changes when the door is touched points more toward the latch or power feed.
A marginal latch is one of the fastest, most common reasons a dishwasher starts then stops, and it often shows up as an intermittent problem.
Next move: If the cycle runs normally once the door is fully seated, clean the latch area and correct anything preventing a tight close. If pressing on the door changes nothing, keep going. The stop is more likely tied to water level or drain trouble.
What to conclude: A dishwasher that only runs with door pressure usually has a worn dishwasher door latch or a door that is not aligning cleanly with the strike.
If water is left in the sump, the dishwasher may stall early, stop advancing, or act like it started and quit.
Next move: If the dishwasher runs farther or completes a cycle after the filter and sump are cleaned, the stop was likely caused by poor draining or restricted water movement. If it still starts then stops, check the float next. If it also leaves water behind every time, the drain hose path may be restricted.
A stuck float can tell the dishwasher it is already full, which can leave it sitting after the first moments of the cycle.
Next move: If the dishwasher fills and continues washing after the float moves freely, the interruption was likely a float issue rather than a failed major component. If the float moves freely, the door latch is solid, and the dishwasher still stops early, the problem is likely beyond the simple homeowner checks.
After the simple checks, one clean test tells you whether you solved it or whether the machine needs deeper diagnosis.
A good result: If it completes the early wash portion normally, keep using it and recheck for recurring latch or drain symptoms over the next few cycles.
If not: If it still starts then stops and you have ruled out the simple causes, stop buying guess-parts and have the unit tested for internal switch, motor, or control faults.
What to conclude: You have narrowed the problem to either a confirmed latch issue or a deeper fault that needs meter-based diagnosis.

Most often it is either pausing normally, losing the door-latch signal, or stalling because of standing water, a clogged dishwasher filter, or a stuck float. The first clue is whether the lights stay on and whether pressing on the door changes anything.
Yes. Many dishwashers pause during fill, soak, sensing, or heating. If the lights stay on and it resumes after several minutes, that can be normal. If it goes dead or only runs when the door is pushed, that is not normal.
Yes. If the latch does not stay engaged, the dishwasher can stop immediately as if the door opened. A strong clue is a cycle that resumes or changes when you press on the door.
It can. A badly clogged dishwasher filter can leave water in the bottom and interfere with normal circulation or drain-out, which can make the cycle stall or fail to advance properly.
Not first. On this symptom, a control board is far less likely than a door latch problem, a drain restriction, or a stuck float. Rule out the simple physical causes before paying for deeper electrical diagnosis.
