SHP78CM2N: model-specific checks
Start with the source identity
Bosch SHP78CM2N is the exact code in this catalog record. This topic should be evaluated for that code and dishwashers category. The original source record is linked below; unrecorded settings, dates and compatibility remain unknown.
Use symptoms and safe observations to decide whether a dishwasher issue is a loading, supply, drain, drying, or service problem.

Describe the failure precisely
Start with what changed: cycle fails to start, dishes remain dirty, water stays in the tub, drying is poor, or water escapes. Note whether the issue happens every time, only on one cycle, or after a recent move or plumbing change. A symptom pattern is more useful than a broad label such as “broken.”
Look for a displayed code or indicator and photograph it before clearing anything. Codes are specific to model families, so do not interpret a number using a search result for another brand. Record the cycle and options selected; some wash and drying options intentionally add time or fan operation.
Rule out loading and detergent causes
For poor cleaning, check whether dishes block spray-arm rotation, the detergent cup, or a lower wash path. Confirm the filter is clean and correctly seated. If a specific rack remains dirty, compare its spray coverage and loading pattern with an otherwise similar load rather than changing detergent and options together.
Use automatic-dishwasher detergent only. Consider cycle length and product form when a tablet remains partly dissolved. A rinse-only cycle may not dispense detergent, while a short wash may use a different placement on some models. Confirm the machine’s own instructions before diagnosing a dispenser failure.
Check the water and drain clues
If filling seems weak, compare the kitchen faucet flow with its usual flow and see whether other household fixtures are affected. A temporary supply issue can mimic an appliance fault. Do not open the dishwasher cabinet or manipulate the inlet valve. If the faucet is normal but the machine still does not fill, collect the cycle stage and any indicator for support.
If water remains after a cycle, inspect only accessible filter and air-gap areas, if present. A disposer connection or shared drain can be obstructed. A high drain loop or air-gap arrangement is installation-specific; do not change hose routing based on a generic diagram. Repeated standing water, sewage odor, or leakage needs prompt assessment.
Separate drying behavior from failure
Plastic items often retain droplets, and condensation drying may leave more moisture than heated drying. Open the door only as directed by the machine’s cycle guidance. Some fan-assisted models continue drying after the wash ends; other designs may open the door automatically. Do not treat a fan or door motion as universal behavior.
If glass and ceramic items are also wet, check rinse-aid supply, loading that traps water in cups, and the selected drying option. Use the exact product support page for design-specific advice. A change in sound or drying result after a filter clean can be useful evidence, but it does not prove a particular component failed.
Choose a service path with clear evidence
Before contacting support, gather the model identifier, code or indicator, cycle, approximate point of failure, and whether water is present. Take a photo of a visible leak or damaged rack component. For a one-time poor-cleaning load, first correct an obvious obstruction and compare again; for a recurring drain, fill, or leak fault, do not keep rerunning cycles to see if it clears.
If repair is needed, ask what diagnosis and parts are included in the estimate, whether travel or inspection is charged, and whether tax or follow-up visits are separate. Compare the total quoted amount with replacement options using your own constraints and the Energy Department’s energy-use information, rather than relying on a generic repair-cost average.
What to do with what you find
The same fill, drain, or leak symptom repeats after accessible checks.
A component or installation issue may require diagnosis beyond owner observations.
Stop repeated cycles and contact model support with the timing, code, and water evidence.

Common questions
Can an error code from another brand help diagnose mine?
No. Use the code list for the exact model family.
Should I cancel a cycle to inspect a suspected leak?
If water is escaping, avoid further operation and use the owner’s cancel procedure only if it can be done safely.
