Bauknecht Function‑Specific Earth Leakage

Oven trips the RCD (residual current device) only when a specific function (e.g. grill) is used.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Specific heating element insulation breakdown, Moisture ingress in that element, Damaged wiring for that function, Faulty fan motor in that mode

Safety first: Disconnect power before testing.

Identify function: Note which mode causes the trip (e.g. grill, fan bake).
Test associated element: Disconnect and insulation‑test the element used in that mode (e.g. grill element). Replace if insulation to earth is low.
Check associated wiring: Inspect and repair any damaged wires or connectors for that circuit.
Fan motor: If the mode uses a specific fan, test the motor for leakage to earth and replace if faulty.
