Possible Causes

Defective mode selector button PCB, Damaged ribbon cable between display panel and main PCB, Liquid ingress into control panel, Firmware glitch in user interface board

How to Fix / Troubleshooting

Safety first: Remove the battery before inspecting the handle or control panel area.

  • Step 1 – Power cycle: Remove the battery for 5 minutes, then reinstall and test. Sometimes a temporary UI communication error clears with a full power cycle.
  • Step 2 – Inspect buttons: Check that the mode button is not stuck or physically damaged. Press it repeatedly to free any minor sticking caused by dust.
  • Step 3 – Check for moisture: Look for condensation or liquid traces around the display and buttons. If present, leave the unit in a dry, warm (not hot) area for 24 hours with the battery removed.

When to call a technician: Persistent E8 usually indicates a failed control panel PCB or ribbon cable. These parts require disassembly of the handle and should be replaced by a service center.
