What the symptom
can tell you.
The most useful first distinction is whether the dishwasher never attempted to drain, tried and stopped, or drained slowly. Sounds, error codes and recent plumbing changes provide important context.
Distinguish sump water
from a failed drain.
Some dishwashers retain a small amount of water below the visible filter area. Water covering the tub floor, returning after a drain cycle or carrying debris is a different pattern.
Note whether the cycle completed, stopped with an error or produced a drain sound without moving water.
Inspect the parts
meant to be cleaned.
- A removable filter for food debris or misplaced labels
- The visible drain area for a loose utensil or fragment
- The drain hose under the sink for an obvious kink
- Whether a recently replaced garbage disposal was connected correctly
Turn off power before reaching into the tub and protect your hands from glass. Do not dismantle pumps, wiring or sealed connections.
Leaks and electricity
end the experiment.
Stop using the dishwasher if water is spreading under cabinets, approaching an outlet, or appearing beneath the appliance. A burning smell, damaged cord or repeated breaker trip also requires immediate shutdown.
If dirty water returns from the sink or disposal, the household drain path may also need attention.
Give the technician
a clean starting point.
Remove dishes, but leave any error code or photo available. Keep the model number and cycle name ready. Clear the sink cabinet enough to view the drain connection without disconnecting it.
