E6 displays and the cooker will not heat or start a program.

Safety first: Unplug the multicooker and allow it to cool. Heating circuit work involves mains voltage; proceed only if you are comfortable and qualified.

• Visual inspection: Turn the unit upside down and remove the bottom cover. Inspect the heating element ring around the base of the inner pot area.
• Check connectors: Look for loose, discolored, or burned spade connectors where the element connects to the wiring harness. Reseat any loose connectors and replace any that are heat-damaged.
• Continuity test (advanced): With a multimeter set to ohms, measure across the heating element terminals. An open circuit (OL) indicates a failed element.
• Inspect control board: Examine the main PCB for burned spots near the heater relay or triac. A strong burnt smell or visible charring indicates board failure.
• Reassemble and test: If connectors were loose but the element tests good, reassemble and test a low-heat mode. If E6 persists, further component replacement is needed.
• Replacement: Replace the main heating element ring if it is open or physically damaged. If the element is good but the board is burned, the main control board must be replaced by a qualified technician.
