Dyson Cordless Vacuum Dust Canister Is Full

If your Dyson cordless vacuum battery flashes the Amber light, check the dust canister and be sure it is not overfilled. If the canister gets too full, the vacuum may stop working and the Amber light will flash. Empty the canister and try again. Charge the vacuum if needed.

Dyson Cordless Vacuum Thermal Cut-Out

The cordless Dyson vacuum is fitted with an automatically resetting thermal cut-out switch. If large items block the tools, nozzle, or any part of the vacuum becomes blocked, the machine may overheat and automatically cut out. Let the vacuum sit to cool down for 1-2 hours before checking the filter or for blockages. Ensure the machine is disconnected from the charger before looking for blockages. Clear any blockage before restarting. Refit all parts securely before using.

Dyson Cordless Vacuum Charging and Storage

To help prolong battery life, avoid recharging immediately after a full discharge. Allow cooling for a few minutes. The cordless Dyson vacuum will switch OFF if the battery temperature is below 37.4°F (3°C). This is designed to protect the motor and battery. Do not charge the machine and then move it to an area with a temperature below 37.4°F (3°C) for storage purposes.
