Bauknecht dE

Bauknecht error code DE indicates: Bauknecht ProFresh & Dynamic0° Total NoFrost Refrigerator: Defrost circuit failure dE; electric heating element failed to warm evaporator coil sufficiently during scheduled defrost cycle..

The primary root cause for Bauknecht code DE is: On Bauknecht refrigerators (Bauknecht Zen Motor Direct Drive brushless BLDC and L1373 / DEA700 power control architecture): Open-circuit calrod heating element (~160 Ω to 260 Ω), blown in-line thermal fuse (72°C), or stuck defrost relay contacts on PCB..

To resolve error code DE: Disconnect mains. Remove freezer evaporator cover. Measure defrost heater resistance (~160–260 Ω) and thermal fuse continuity (<1 Ω). Replace defective component. Hold Alarm Reset button for 3 seconds until alarm indicator turns off and evaporator fan resumes normal cycle.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bauknecht code DE persists, the physical component causing On Bauknecht refrigerators (Bauknecht Zen Motor Direct Drive brushless BLDC and L1373 / DEA700 power control architecture): Open-circuit calrod heating element (~160 Ω to 260 Ω), blown in-line thermal fuse (72°C), or stuck defrost relay contacts on PCB. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

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.
