Dyson V11, V12 and V15 showing “Runtime remains on screen but the vacuum cuts out” has a specific manufacturer-backed troubleshooting path. Match the exact light, sound or behaviour before cleaning, resetting or ordering anything. Confirm “Runtime remains on screen but the vacuum cuts out” exactly, including the full number, colour, flash order, spoken phrase or screen text. If any element differs, use the guide for that other indication instead. Dyson — V15 troubleshooting documents this condition for Dyson V11, V12 and V15. It identifies the branch to test, but it does not by itself prove that a battery, motor, board, sensor, dock or replaceable part has failed. Do not treat the displayed minutes as proof of battery failure. Remove all tools, empty the bin and test ten seconds; if it pulses, inspect the removable air path and fully dry filter, then retest once in Eco mode after cooling. Switch the vacuum off and disconnect its charger or mains plug before removing an accessible tool, bin, filter or brush. Never open the motor body, charger or battery pack. Run only one normal start, charge or cleaning cycle after the documented check. If “Runtime remains on screen but the vacuum cuts out” returns unchanged, record the code, model and serial number and contact authorised Dyson support instead of repeating resets or guessing a part.

Checks in the right order

  1. Identify the exact indication

    Confirm “Runtime remains on screen but the vacuum cuts out” exactly, including the full number, colour, flash order, spoken phrase or screen text. If any element differs, use the guide for that other indication instead.

  2. Safe check to perform

    Do not treat the displayed minutes as proof of battery failure. Remove all tools, empty the bin and test ten seconds; if it pulses, inspect the removable air path and fully dry filter, then retest once in Eco mode after cooling.

  3. What to do after the test

    Run only one normal start, charge or cleaning cycle after the documented check. If “Runtime remains on screen but the vacuum cuts out” returns unchanged, record the code, model and serial number and contact authorised Dyson support instead of repeating resets or guessing a part.

Stop and get qualified help when

  • Stop for a swollen or unusually hot battery, burning or electrical smell, smoke, liquid ingress, a damaged lead, sparking or harsh motor noise. Run only one normal start, charge or cleaning cycle after the documented check. If “Runtime remains on screen but the vacuum cuts out” returns unchanged, record the code, model and serial number and contact authorised Dyson support instead of repeating resets or guessing a part.

Next step

Repair, replace a part, or arrange a diagnosis?

Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.

Resolve it without buying anything

Complete the 3 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.

Replace only the confirmed part

If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.

This guide does not identify a replacement part. Do not order a generic component from the symptom alone.

Arrange a diagnosis before replacing the appliance

Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
