Oven display flickers or dims when heating elements switch on

Safety first: Turn off power before tightening terminals or opening the oven.

• Check circuit loading: Ensure the oven is on a dedicated circuit as recommended by Brandt. Avoid running other high‑power appliances on the same circuit.
• Inspect terminal block: Tighten all screws at the oven's mains terminal block. Loose connections can cause voltage drops and heating.
• House wiring check: If lights in the house also dim, have an electrician check the supply and distribution board.
• Control board repair: If only the display flickers and the supply is stable, the low‑voltage capacitors on the control board may be failing. Replace the main control board.
