Reported symptom
The dishwasher was not draining and the drain pump was not operating.

Miele Dishwasher Not Draining
Standing water needs a clear diagnosis, not an assumed pump replacement. A real G 2142 SCi service record and the matching Miele operating manual show why.

What the symptom actually tells you
When water stays in the tub, the investigation follows the path the water should take: filters, the pump area, non-return components, hose routing, an air gap where fitted, and the household drain. On the Miele G 2142 family, Miele's own operating instructions specifically point to the filter combination, drain pump, non-return valve and a kink or restriction in the drain hose when water is not pumped away.
A fault code narrows the question without naming a part: Miele documents F13 as a water-inlet condition, not a failed drain pump. Diagnosis is a paid on-site visit followed by a written estimate.
From the field
Miele G 2142 SCi — foreign objects in the drain pump
A real KONGRA service record, kept separate from the general troubleshooting guidance below.
Finding & work performed
Foreign objects were blocking the drain pump. The pump area was disassembled, the obstruction removed, and cleaning, unclogging and maintenance performed before reassembly.
What this record does not establish
No pump replacement is documented. The available service notes do not record the final functional drain-test result, so no additional tested outcome is claimed here.
Differentiate
Which pattern matches what you are seeing
These are categories to narrow the question before a visit, not a remote diagnosis. Confirmation requires on-site measurement.
What you observe
What it points toward
- Water standing in the tub after the cycle endsA drainage question: filters, pump area, hose routing, air gap or the building drain line.
- Dishes dirty but the tub is emptyPrioritize wash coverage and circulation; an empty tub alone does not rule out an intermittent drainage problem.
- Machine stops early, before or during fillingAn early stop alone does not prove an inlet fault. Where an exact F13 is shown, Miele identifies that code as a water-inlet condition; otherwise the filling you observed and a model-specific assessment decide.
- Sink backs up, or a countertop air gap overflowsSuggests the restriction may be downstream of the appliance. Note recent plumbing or disposal work too.
Safe to check
What you can safely observe yourself
Observations only. No tools, panels, water connections or electrical parts.
Owner observations
- Note whether water remains in the tub, and where the cycle stopped
- Record the model number and photograph any code shown
- Check whether the sink drains normally and whether a visible air gap overflows
Do not attempt
- Do not disconnect the drain hose or any water connection
- Do not pull the dishwasher out or open the pump area
- Do not work on the appliance while it is energized
Professional assessment
What requires a technician on site
Assessed during a diagnostic visit
- Tracing the drain path the model uses, with installation and air-gap condition
- Separating an appliance restriction from a building drain-line restriction
- Reading model-appropriate service data and fault history; documenting an actual functional drain check after corrective work
Model and scope boundaries
- Drain arrangement and pump access differ by model — the rating plate determines the procedure
- An inlet-stage code is not evidence of a drain-pump fault
- Commercial warewashing is separate; plumbing beyond the appliance connection may require a licensed plumbing contractor
Diagnostic information
Useful observations
- Model number and the exact code displayed
- Whether water remains in the tub at the end of the cycle
- Whether the sink drains normally and whether an air gap is fitted
- Any recent plumbing, disposal or installation change

Documented service record
Miele G841: restoring drainage
During a Los Altos Hills service visit, the technician documented standing water, a blocked air gap and a displaced seal. The air gap was cleared and the seal repositioned. The entry confirms drainage was restored and the dishwasher operated properly during the check — not that every standing-water complaint needs the same work.
Documented diagnosis — no completed repair confirmed
G4228SCU: F13 intake diagnosis and recommendation
A documented diagnostic visit showed F13 with an Intake/Drain indication, while pressure and drainage were recorded as normal. The intake assembly and flow measurement were suspected and replacement recommended; the record confirms the recommendation only, not a completed repair or outcome.

FAQ
Frequently asked questions
Does standing water mean the drain pump has failed?+
No. Filters, the pump area, hose routing, an air gap where fitted or the household drain can each hold water in the tub. The pump is confirmed by inspection, not assumed.
Is an F13 fault a drainage problem?+
Miele documents F13 as a water-inlet condition, not a drain-pump diagnosis. The exact model, the exact code and what you observed during filling all matter.
What does Miele list for a G 2142 that is not draining?+
For the G 2142 family, Miele's operating instructions point to the filter combination, drain pump, non-return valve and a kink or restriction in the drain hose when water remains in the cabinet. A technician still confirms the actual cause before recommending a part.
Can I check the air gap or the sink myself?+
You can look: note whether the sink drains normally and whether a countertop air gap overflows. Dismantling or reaching into the pump is not safe.
