Electric oven shows E50 and the grill function does not operate.

Safety first: Disconnect mains power and allow the oven to cool.

• Visual inspection: Check the grill element at the top of the oven for visible breaks, bulges, or burn marks.
• Continuity test: Access the rear of the cooker and locate the grill element terminals. Disconnect one wire and measure resistance; an open circuit indicates a failed element.
• Check wiring: Inspect the wires and terminals for heat damage. Replace any charred connectors and trim back damaged wire before fitting new terminals.
• Control relay: If the element and wiring are good but the grill never receives power, the grill relay on the electronic control board may be defective. Replace the board.
• Test grill: After replacing the element or board, run the grill at a low setting first to confirm operation and check for abnormal smells or smoke from new parts.
