E6 error appears shortly after starting a program; cooker may not heat properly.

Safety first: Unplug the multicooker and allow it to cool. Internal electrical checks should only be done if you are comfortable and the unit is out of warranty.

• Basic reset: Disconnect power for 10 minutes, then plug back in and test a simple program. If E6 returns immediately, proceed to inspection.
• Check for obvious damage: Turn the unit over and remove the bottom cover. Look for burnt smells, discoloration, or melted insulation near the heater connections.
• Inspect heater terminals: Locate the two main heater terminals on the underside of the heater plate. Ensure both spade connectors are tight and not oxidized or broken.
• Check thermal fuse: Many Black+Decker multicookers include an inline thermal fuse attached to the heater plate wiring. If it appears burned or open (bulged or discolored), it must be replaced with the same rating.
• Control board inspection: Examine the main PCB for a burned heater relay (darkened area, cracked solder joints). If damaged, the control board will need replacement.
