E10 appears; unit may not respond to temperature or time settings correctly.

Safety: Unplug the air fryer before working on the control panel.

• Dry out panel: If the panel was recently wiped with a wet cloth or exposed to steam, leave the unit unplugged for 24 hours in a dry environment and retry.
• Inspect front panel: Check for cracks in the glass/plastic touch surface or signs of liquid under the panel.
• Open control housing: Remove screws around the control panel and gently lift it to access the touch panel / keypad PCB and its connector.
• Check connector: Ensure the keypad ribbon or plug is fully seated on the main PCB. Reseat it to clear any poor contact.
• Look for corrosion: If there is visible corrosion or residue on the keypad PCB, clean carefully with isopropyl alcohol. Severe damage will require replacement.
• Replace keypad/touch panel: If specific buttons never respond or E10 persists, replace the complete touch control panel assembly for your Russell Hobbs model.
• Reassemble and test: Refit the panel, ensuring no wires are pinched, and test all buttons and functions.
