Bauknecht E2

Bauknecht error code E2 indicates: Bauknecht PowerClean & GentlePower MaxiSpace Pro Dishwasher: AquaStop base pan float switch closed E2; emergency drain activated to prevent residential water flooding..

The primary root cause for Bauknecht code E2 is: On Bauknecht dishwashers: Sump seal failure, loose hose clamp on circulation pump volute, split water matrix air-break, or leaking door lower gasket..

To resolve error code E2: Unplug unit. Sponge dry base tray. Inspect circulation motor and sump gaskets for active drips. Replace defective hydraulic joint or hose. Hold Reset/Cancel button for 3 seconds until drain pump evacuates water and LED displays '0:01'.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bauknecht code E2 persists, the physical component causing On Bauknecht dishwashers: Sump seal failure, loose hose clamp on circulation pump volute, split water matrix air-break, or leaking door lower gasket. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
