Oven display shows E8, interior light may flicker, some functions unavailable

Safety first: Switch off the circuit breaker and verify absence of voltage before opening the terminal area. Mains components can be lethal.

• Check wall supply: Use a multimeter to verify that the outlet or terminal block supplies the correct voltage (typically 220–240 V AC in Severin markets). If low, consult an electrician.
• Inspect mains terminal block: Remove the rear cover to access the mains connection. Tighten all screws on the terminal block and check for signs of overheating or melted plastic.
• Examine EMI filter: Locate the mains filter module. Look for cracks, bulging, or burn marks. Replace if damaged.
• Control board power section: On the control PCB, inspect the power supply components (transformer or SMPS, rectifier, capacitors). Swollen capacitors or burnt resistors indicate failure.
• Replace faulty parts: If the power supply section is damaged, the safest solution is to replace the entire control PCB with a genuine Severin part. If only the mains filter is faulty, replace it with the same rating.
• Test: After reassembly, restore power and verify that E8 is cleared and all functions operate normally.
