Morphy Richards oven shows E10 and the display is blank or flickers when attempting to start.

Safety first: Isolate the oven at the mains. High voltages are present at the terminal block.

Steps:

• Check supply: Verify that the wall isolator or cooker switch is supplying correct voltage and is not loose or burnt.
• Inspect terminal block: Remove the rear cover to access the oven's mains terminal block. Look for discoloured plastic, loose screws, or melted insulation.
• Tighten/replace: Tighten any loose terminals and replace the mains terminal block if heat damage is evident.
• Check mains filter: Many Morphy Richards ovens use an EMI filter module. Inspect for bulging capacitors or burn marks. Replace the mains filter module if faulty.
• Control board: If external connections are sound but E10 persists, the internal low-voltage power supply on the electronic control board may have failed and the board should be replaced.

Note: If you smell burning or see smoke, do not re-energise the oven until it has been inspected by a professional.
