Direct answer
A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. 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
ReversibleRecord the change, version, outage time or newly connected hardware and the last known working state. 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. Remove or roll back only the reversible change, or test the previous direct path. 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. Reapply compatible settings, update both endpoints or replace the incompatible new path.
Verify and stop safely
ReversibleRestart twice and confirm the feature remains stable with the intended change present. 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.
