Direct answer
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. For dishwasher circulation pump and spray, first listen after fill, mark arm position and run a short empty wash.
What this covers
- dishwasher circulation pump and spray with this exact failure state
- Diagnosis across fill level/filter/spray arms versus circulation motor and diverter
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleWrite down the selected mode, input conditions and the exact unexpected output. Expected behavior: move wash water through rotating spray arms at useful pressure.
Isolate the component boundary
ReversibleListen after fill, mark arm position and run a short empty wash. Use a known reference input or manufacturer test and compare the result. Boundary to separate: fill level/filter/spray arms versus circulation motor and diverter.
Correct only the proven cause
ReversibleClean/reseat filter and approved spray holes or service absent circulation. Correct the setting, calibration or component proven by that comparison.
Verify and stop safely
ReversibleRepeat with the reference and a normal real-world case. Stop for grinding, burning smell, leaks or broken glass near the pump.

Common follow-ups
What should I check first when dishwasher circulation pump and spray has this problem?+
Listen after fill, mark arm position and run a short empty wash.
Why not factory-reset immediately?+
The useful boundary is fill level/filter/spray arms versus circulation motor and diverter. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
stop for grinding, burning smell, leaks or broken glass near the pump.
