E6 error appears and cooker will not start; sometimes occurs after a power surge or lightning event.

Safety first: Disconnect from mains before opening the housing. Capacitors on the PCB can retain charge; avoid touching bare solder joints.

Steps to attempt:

• Power reset: Unplug the cooker for at least 10 minutes to allow internal capacitors to discharge, then plug back in and test. Sometimes this clears transient faults.
• Inspect PCB visually: Remove the top or side cover to access the control PCB (behind the display and buttons). Look for burnt components, bulging capacitors, or cracked solder joints.
• Check connectors: Reseat all harness connectors to the PCB (heater, sensors, lid switch, pressure sensor). A poor connection can trigger self-test errors.
• Surge damage: If there are visible burn marks or a strong burnt smell from the PCB, the board is likely beyond simple repair.
• Replace PCB: Order the correct Morphy Richards control PCB for your exact model number. Transfer any detachable wiring looms one by one to avoid misconnection, then reassemble and test.

Warning: Component-level repair of the PCB should only be attempted by trained electronics technicians. For most users, full PCB replacement is the safest option.
