Bosch Dishwasher Error Codes and Solutions

Bosch dishwashers are among the most trusted appliances in Azerbaijan, known for German engineering and reliability. However, like any appliance, they can develop issues over time. Error codes on the display help identify the problem — but resolving it requires professional intervention. Güvən Servis has over 15 years of Bosch dishwasher repair experience.

Water Intake Errors

• E14 — Flow meter fault: The machine cannot correctly measure incoming water flow.
• E16 — Water fill error: Unexpected water intake detected. Possible inlet valve malfunction.
• E17 — High water level: Water level inside the machine exceeds normal range.
• E18 — Fill timeout: The machine failed to fill with enough water within the allotted time.

Water intake issues typically stem from valve, filter, or sensor malfunctions. Contact our dishwasher repair service.

Drainage Errors

• E21 — Drain pump fault: The pump is not functioning and water cannot be evacuated.
• E22 — Blocked filter: Food residue has clogged the drainage filter.
• E24 — Drainage issue: The drain hose is kinked, compressed, or blocked.
• E25 — Drain pump clog: A foreign object is blocking the pump impeller.

Improper interference with the drainage system can cause leaks and electrical short circuits. Do not attempt to repair this yourself — it can cause further damage.

Heating System Errors

• E01 — Water heating error: The machine fails to heat water to the required temperature.
• E02 — NTC sensor fault: The temperature sensor provides incorrect readings.
• E09 — Heating element (TEN) fault: The heating element has burned out or short-circuited.

Due to hard water in Baku, limescale buildup on the heating element is extremely common. Replacement requires professional expertise.

Leak Protection (Aquastop)

• E15 — Aquastop activated: Water detected in the protective tray. The machine shuts down immediately to prevent flooding.

If you see E15, disconnect the machine from power immediately and call: +994 55 958 38 39.

Why Professional Diagnosis Matters

A dishwasher's electronics form a complex system. A single error code can have multiple causes. Unqualified interference can make things worse. Trust experienced technicians.
