Possible Causes
Blown internal fuse, Damaged power supply components, Surge-damaged main PCB, Faulty mains cable
How to Fix / Troubleshooting
Safety first: Unplug from the mains. Do not attempt to open the power supply if you are not qualified.
- Check outlet: Test the wall outlet with another appliance to confirm power is present.
- Inspect mains cable: Look for cuts, kinks, or burn marks on the cable and plug. Do not use the machine if damage is visible.
- Try another outlet: Plug into a different, known‑good outlet without extension leads or surge strips.
- Service recommended: If E15 persists, internal fuses or surge components may have failed. These are not user‑serviceable; contact a Dyson‑approved service centre.
