Cordless vacuum display shows E5 and the unit will not start, often after being dropped or knocked.

Safety first: Remove the battery pack and ensure the charger is unplugged. Do not open the main body if your model is still under warranty; contact Salter support.

External checks:

• Inspect for moisture: Check for signs of liquid spills or condensation around the handle, display, and vents. If the vacuum has been exposed to moisture, leave it in a warm, dry room for 24–48 hours with the battery removed.
• Check battery fit: Ensure the battery clicks firmly into place. A loose connection can mimic a PCB fault.
• Try a different battery: If you have a second compatible Salter battery, test with it to rule out a battery communication issue.

Internal inspection (advanced users only):

• If out of warranty and comfortable with small electronics, remove the screws on the main body shell and carefully separate the halves.
• Inspect the main PCB for burnt components, cracked solder joints, or loose connectors from the battery and motor.
• Reseat any plug-in connectors firmly. Do not short any components.

If E5 persists, the main control PCB will likely need replacement as a complete module. This is typically a level of repair best handled by a service centre.
