Possible Causes

Failed motor start capacitor (if fitted), Faulty motor driver circuit on control PCB, Open circuit in motor windings, Loose motor wiring connector

How to Fix / Troubleshooting

Safety first: Remove the battery pack and do not connect the charger while inspecting. Internal electrical repairs should only be done by qualified personnel.

User-level checks:

  • 1. Confirm battery status: Ensure the battery is fully charged and correctly latched into the handle. Try a second battery if available.
  • 2. Check for blockages: Severe blockages can sometimes prevent the motor from starting. Remove hose, wand, and tools and check for obstructions.
  • 3. Listen for clicks or beeps: When you pull the trigger, note whether you hear a relay click or brief attempt to start. No sound at all can indicate a control PCB issue.

Beyond this point: Accessing the motor, start capacitor, or control PCB requires opening the Henry cordless body, which can expose you to live circuits and void warranties.

When to stop: If the unit still shows E5 after basic checks, arrange service. The motor unit or control PCB will likely need testing and replacement.
