How to Fix / Troubleshooting
Safety: Unplug the Ewbank cleaner before accessing internal wiring.
- Check mains supply: Plug directly into a known-good wall outlet without an extension.
- Inspect connectors: Remove the housing and gently press all wiring harness connectors into the control PCB until fully seated.
- Visual inspection: Look for burnt components or bulging capacitors on the PCB. Do not touch components if you are not trained.
Persistent flickering and speed changes usually indicate a failing control board or motor and should be serviced professionally.
