Flashes red and blue
Rowenta Flashes red and blue stick vacuum: charger mismatch
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
When the charger is connected to your Rowenta X-Force Flex vacuum and the battery indicator flashes red and blue alternately (or charging lights flash very quickly), unplug it: check that you are using the original compatible Rowenta charger or have an Authorized Service Centre replace it.
Safety first
Stop and check this first
- If the power cord of your appliance is damaged, do not use your appliance; to avoid any danger, have it replaced by an approved repair centre and never use non-original chargers.
- Never open, puncture, bridge, or charge a swollen, hot, smoking, or damaged lithium-ion battery pack, and do not open the mains charger or dock internals yourself; stop immediately and use an Authorized Service Centre.
Safe checks you can perform
- Check that the connected charger is the original unit for your Rowenta model
- Inspect the power cord for damage and verify the plug connection
- Confirm room temperature is between 0°C and 40°C and inspect battery condition
Leave these tasks to a qualified professional
- Do not attempt this professional task: Verify charger compatibility and replace a faulty charger or cord at an Authorized Service Centre
- Do not attempt this professional task: Inspect the battery pack and charging circuit if red flashing persists

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Verify charger compatibility and replace a faulty charger or cord at an Authorized Service Centre
What they doAn Authorized Service Centre tests the charger output and replaces a faulty charger or damaged power cord with the correct Rowenta unit.
They must show youthe battery indicator charging normally when connected to a verified compatible Rowenta charger.
In writingwhether the original charger tested faulty and the part reference of the replacement Rowenta charger.
Inspect the battery pack and charging circuit if red flashing persists
What they doIf a verified compatible charger at 0°C to 40°C still triggers red flashing on the battery or Smart Control display, the Authorized Service Centre inspects the battery pack and vacuum.
They must show youdiagnostic test results comparing your battery pack with a service test battery on an approved charger.
In writingthe service center findings on the battery pack and charging connectors without opening lithium-ion cells.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check that the connected charger is the original unit for your Rowenta model
- Who:
- you, next to the wall outlet and your Rowenta X-Force Flex battery pack.
- How:
- unplug the charger from the mains socket, inspect the label on the adapter body, and confirm it is the original charger supplied with your Rowenta X-Force Flex vacuum rather than a cord from another device.
- Result that matters:
- rule out an incompatible adapter that triggers red and blue alternating flashes.
- If a different appliance's adapter was plugged in by mistake:
- switch to the original compatible Rowenta charger.
- If you are already using the original Rowenta charger:
- inspect the power cord and plug seat next.
- Evidence to keep:
- photo of the charger rating label alongside your vacuum reference (such as RH9AD1WO or RH99F1WO).

Inspect the power cord for damage and verify the plug connection
- Who:
- you, with the charger disconnected from the wall socket.
- How:
- check the entire length of the charger cord and plug for cuts or damage (if the power cord is damaged, do not use the appliance), then firmly reconnect an undamaged original charger directly to the battery and test a known-working wall socket.
- Result that matters:
- ensure the charger is properly seated without operating a damaged mains cord.
- If reseating the undamaged original charger in a working socket restores normal charging lights:
- it was a loose connection.
- If the battery indicator still flashes red and blue alternately or flashes very quickly:
- unplug it and check the room temperature.
- Evidence to keep:
- short video showing the battery indicator flashing red and blue when connected.

Confirm room temperature is between 0°C and 40°C and inspect battery condition
- Who:
- you, in an indoor room with the charger unplugged from the battery.
- How:
- verify that the battery is in an environment between 0°C and 40°C (a red flashing battery light on charger connection indicates temperature outside 0°C to 40°C or a battery issue) and check that the lithium-ion pack is not swollen, deformed, or abnormally hot.
- Result that matters:
- confirm whether the charger itself requires replacement at an Authorized Service Centre.
- If the room is between 0°C and 40°C and the indicator still flashes red and blue:
- take the charger to an Authorized Service Centre.
- If the battery pack is swollen, smoking, or hot:
- stop immediately, do not charge it, and arrange professional service.
- Evidence to keep:
- ambient room temperature and the exact LED flash pattern observed.

What it means
On Rowenta official instructions for use and FAQ pages for the X-Force Flex 13.60 (RH9AD1WO) and X-Force Flex 15.60 (RH99F1WO) cordless stick vacuums, the battery indicator flashing red and blue alternately while the charger is connected (or the charging light flashing very quickly) means the charger is not the correct model or is faulty. Other Rowenta cordless models may differ in LED display patterns, and this flashing signal alone never proves the battery pack or internal electronics have failed.
