Direct answer: When a dishwasher cycle will not complete, the most common causes are standing water that keeps it from advancing, a dirty filter or blocked drain path, a door latch that is not staying made, or a stuck overfill float. Start with the tub and drain path before assuming an electronic failure.
Most likely: On most machines, this turns out to be a drain problem or a simple interruption like the door not latching cleanly.
First pin down the pattern. A dishwasher that stops with water in the bottom is a different job than one that runs a long time with no water left, or one that pauses when the door shifts. Reality check: many "stuck cycle" calls end up being a filter packed with grease and food paste. Common wrong move: forcing the timer ahead or killing power over and over without checking for standing water first.
Don’t start with: Do not start by ordering a dishwasher control board or tearing into wiring. Those are not the first bets on this symptom.
The cycle pauses or ends early, and there is dirty water sitting in the sump or across the tub floor.
Start here: Go straight to the filter, drain area, air gap if you have one, and the dishwasher drain hose path.
The dishwasher seems to wash forever, then may finish late or need to be canceled.
Start here: Check for a partially restricted filter or drain path first, then look for a float or latch issue interrupting normal progress.
Lights stay on or flicker, but the cycle pauses when the door shifts or needs to be pushed to continue.
Start here: Inspect the dishwasher door latch and strike area before chasing anything deeper.
You hear filling or short bursts of noise, but spray sounds are weak and the cycle does not move along normally.
Start here: Check the overfill float for a stuck-up position and make sure the filter area is not packed with debris.
When the filter is packed, water movement slows down and the machine may never drain or reset cleanly into the next part of the cycle.
Quick check: Pull the lower rack, remove the filter if your model has a removable one, and look for grease sludge, labels, glass chips, or food paste.
A kinked dishwasher drain hose, clogged sink air gap, or blockage where the hose meets the sink drain can leave water in the tub and keep the cycle from finishing.
Quick check: Look for standing water, then inspect the hose routing under the sink and clear the air gap cap if your sink has one.
If the latch opens electrically or mechanically for even a moment, many dishwashers pause the cycle and wait.
Quick check: Close the door firmly and see whether it feels loose, needs upward pressure, or pauses when you press on the top corners.
A float stuck in the up position can tell the dishwasher it is already full, which throws off filling and cycle progress.
Quick check: Find the float inside the tub floor area and make sure it moves up and down freely without grit or hard buildup around it.
Standing water is the clearest early split. If water is still in the tub, the dishwasher often is not really stuck on timing at all; it is waiting on a drain problem.
Next move: If you find heavy debris and clear it, you may have already found the reason the cycle would not complete. If there is no standing water, move on to door latch and float checks. If there is water but no visible blockage, keep following the drain-path steps.
What to conclude: Water left behind points first to a restricted drain path, not a bad timer by default.
This is the highest-payoff fix on a dishwasher that stalls, runs long, or stops before draining cleanly. A half-clogged filter can cause weak circulation and slow draining at the same time.
Next move: Run a short rinse or quick cycle. If the dishwasher now drains and advances normally, the filter restriction was the problem. If the cycle still hangs or leaves water, inspect the rest of the drain path under the sink.
What to conclude: A filter packed with debris is a common cause of long cycles, weak wash action, and a machine that never seems to finish.
A dishwasher can look like it has an internal failure when the real restriction is under the sink. Air gaps, hose loops, and sink drain connections are frequent trouble spots.
Next move: If the dishwasher now drains strongly and finishes the cycle, the blockage was in the external drain path. If the drain path is clear and the tub still hangs full of water, the problem may be deeper in the dishwasher and is a good point for service.
A dishwasher that stops when bumped, needs to be pushed closed, or restarts after opening and closing the door often has a latch problem, not a drain problem.
Next move: If cleaning the latch area or correcting a simple alignment issue lets the dishwasher run through normally, the interruption was at the door. If the door feels solid and the symptom is unchanged, check the float next.
A stuck float can interrupt filling and leave the dishwasher washing weakly, pausing oddly, or never progressing the way it should. If the float is free and the easy checks are done, the remaining causes are less DIY-friendly.
A good result: If freeing the float restores normal filling and the cycle completes, you found the fault.
If not: If none of the simple checks change the symptom, deeper electrical or internal pump issues are more likely and are not good guess-and-buy territory.
What to conclude: Once the filter, drain path, latch behavior, and float check out, the remaining problem is usually an internal component or control issue that needs model-specific testing.

That usually means it is hanging on a drain, fill, or door-latch issue rather than truly counting down normally. Check for standing water first, then the filter, drain path, and latch behavior.
Yes. A clogged dishwasher filter can slow circulation and draining enough that the machine runs long, stalls, or never gets through the final drain cleanly.
Weak spray and a cycle that drags on often go together when the filter is packed, the sump is dirty, or the float is interfering with normal filling. Start with cleaning and simple movement checks before assuming a major part failure.
No. On this symptom, a control board is not the first thing to suspect. Drain restrictions, latch interruptions, and float problems are much more common and much cheaper to rule out first.
Not until the filter, air gap if present, hose routing, and sink-side drain connection are confirmed clear. A lot of dishwashers get diagnosed as pump failures when the blockage is outside the pump.
That points strongly to a dishwasher door latch or alignment problem. If the latch signal drops out, the machine pauses the cycle for safety and may seem randomly stuck.
