Not sure where the fault is?
Dishwashers · drain plumbing

Dishwasher air gap overflows onto the sink

Water from the air gap indicates a restriction after the air gap—commonly the hose to the disposal or sink drain—not a reason to remove the air gap.

Open record
Dishwashers · spray system

Dishwasher bottom rack is not getting clean

Bottom-rack failure often follows a blocked lower arm, filter debris, cookware blocking rotation or weak circulation.

Open record
Dishwashers · wash

Dishwasher circulation pump and spray behaves incorrectly or produces the wrong result

A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. This record isolates dishwasher circulation pump and spray through fill level/filter/spray arms versus circulation motor and diverter.

Open record
Dishwashers · wash

Dishwasher circulation pump and spray fails only on one cycle, load or operating condition

An appliance problem limited to one cycle, load, zone or operating condition should be separated from a component that fails every time. This record isolates dishwasher circulation pump and spray through fill level/filter/spray arms versus circulation motor and diverter.

Open record
Dishwashers · wash

Dishwasher circulation pump and spray is not working

A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. This record isolates dishwasher circulation pump and spray through fill level/filter/spray arms versus circulation motor and diverter.

Open record
Dishwashers · wash

Dishwasher circulation pump and spray is unusually slow or delayed

A delay can come from capacity, weak signal, background work, protection or a service wait; measuring the exact stage prevents the wrong repair. This record isolates dishwasher circulation pump and spray through fill level/filter/spray arms versus circulation motor and diverter.

Open record
Dishwashers · wash

Dishwasher circulation pump and spray keeps disconnecting or working intermittently

Intermittent behavior is diagnosed by the trigger—movement, heat, load, sleep, distance or time—not by repeating broad resets. This record isolates dishwasher circulation pump and spray through fill level/filter/spray arms versus circulation motor and diverter.

Open record
Dishwashers · wash

Dishwasher circulation pump and spray stopped working after an update, outage or hardware change

A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. This record isolates dishwasher circulation pump and spray through fill level/filter/spray arms versus circulation motor and diverter.

Open record
Dishwashers · detergent

Dishwasher detergent dispenser behaves incorrectly or produces the wrong result

A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. This record isolates dishwasher detergent dispenser through loading obstruction/wet cup versus latch, cycle progress and spray.

Dishwasher detergent door does not open

A detergent door may be blocked by a pan or rack, stuck by damp detergent, or fail because the cycle never reached the release stage.

Open record
Dishwashers · door

Dishwasher door pops open during the cycle

A door that opens can be caused by a rack or utensil preventing closure, cabinet misalignment, an unlevel installation or a damaged latch.

Open record
Dishwashers · drain

Dishwasher drain system behaves incorrectly or produces the wrong result

A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. This record isolates dishwasher drain system through filter/pump cover/hose/air gap versus disposal plug and household drain.

Dishwashers · noise

Dishwasher hums but does not wash

A brief hum can be a drain or inlet valve, but continuous humming without water movement can mean a blocked pump, closed supply or seized circulation motor.

Open record
Dishwashers · wash quality

Dishwasher leaves a white film on dishes

White film can be hard-water mineral, excess detergent or undissolved detergent—not necessarily food soil. Whether vinegar dissolves a sample helps distinguish mineral from etching, but follow material and manufacturer limits.

Open record
Dishwashers · wash quality

Dishwasher leaves gritty residue on glasses and dishes

Grit usually comes from a dirty or incorrectly seated filter, blocked spray arms, poor loading, low fill or detergent that did not dissolve.

Open record
Dishwashers · racks

Dishwasher rack coating is chipped or rusting

Exposed metal under damaged rack coating can rust and stain the tub or dishes. Cleaning does not restore the protective coating.

Open record
Dishwashers · drain plumbing

Dishwasher smells like sewage

Sewage odor indicates drain backflow, a missing high loop or air gap, a dry/blocked trap or household plumbing problem more than ordinary tub residue.

Open record
Dishwashers · odor

Dishwasher smells like wet dog after a cycle

A wet-dog odor often develops from food residue in the filter, stagnant drain water, dirty seals or dishes drying slowly—not from a need for fragrance.

Open record
Dishwashers · spray system

Dishwasher top rack is not getting clean

Top-rack-only failure points to loading, a blocked upper spray arm, a disconnected rack water feed or insufficient circulation to that level.

Open record
Dishwashers · normal drain state

Is a small amount of water under the dishwasher filter normal?

A small amount of clean water in the sump can protect pump seals, while water covering the tub floor or carrying debris indicates incomplete drainage.

Open record
Dishwashers · detergent emergency

Soap foam is leaking from the dishwasher door

Foam pouring from the door usually means hand dish soap, excessive detergent or spilled rinse aid. Stop the cycle and remove foam before repeated draining.

Open record
Dishwashers · drying

Why are plastic dishes still wet after the dishwasher?

Plastic stores less heat than ceramic or glass, so condensation and residual droplets are common even when the dishwasher dries normally.

Open record
Dishwashers · cycle timing

Why does the dishwasher cycle take much longer than expected?

Modern cycles extend time to compensate for cooler water, soil sensing, energy-saving heat and drying. A sudden increase can also indicate low inlet temperature, excess foam or repeated heating.
