# How to descale a Tefal SV8022G0 steam generator Canonical page: https://everydaygarmentcare.co.uk/care/descale-tefal-sv8022g0/ Publisher: Everyday Garment Care Care & fixes / Model guide Follow the Tefal Express Airglide SV8022G0 scale-flush procedure, from filling the tank to holding Anti Calc and handling the hot discharge. By Everyday Garment Care · Updated November 2026 ![A steam generator and its iron resting on a worktop near a utility sink]() ## Flush through the soleplate using Anti Calc When Anti Calc flashes, switch off and unplug before filling the water tank. Refit the tank, plug in and switch on. Hold the iron over the sink and press the flashing Anti Calc button for three seconds. Hot water and steam come out during the cycle. Wait for the end signal before unplugging. ## Confirm the full SV8022G0 model code The white and dress-blue Tefal Express Airglide **SV8022G0** uses a built-in scale-draining cycle. Check the reference on your appliance when it is unplugged and cool enough to handle. Tefal’s shared Express Anti-Calc and Express Airglide quick-start sheet shows more than one maintenance route. The panel headed **Anti Calc** shows the powered soleplate flush for this model. Other illustrations show a collector coming out of the base or an optional holder for an iron over the sink. The SV8022G0 product instructions describe filling the tank and pressing the button to flush scale. If the hardware or control panel differs from the model guide, check the complete reference again before attempting any maintenance. ## Get the sink and water tank ready Have a clear sink where the water can run away. Put the base on a stable, dry surface nearby. Check that the hose reaches without stretching and that the cord and plug will stay clear of the water. You will hold the iron above the sink with the soleplate aimed into the basin. Avoid leaning over the discharge path. The removable tank is the part shown being filled in Tefal’s diagrams. Keep the base and the iron away from running tap water. Clear the surrounding area so you can return the iron to a stable resting position once the cycle ends. Keep children and pets clear of the area while you handle the hot iron. ## Run the Tefal scale-draining cycle 1. **Switch off and unplug.** Start with the appliance disconnected while you prepare the tank. 2. **Fill the removable water tank** with plain water of the type Tefal permits. Respect the tank’s fill mark and seat the tank securely back in the unit before reconnecting. 3. **Plug in and switch on.** Look for the flashing Anti Calc indicator on the control panel. Use the button labelled Anti Calc rather than the separate Mode button. 4. **Hold the iron over the sink.** Aim the soleplate into the basin. With the iron in position, press the flashing Anti Calc button for **three seconds** to start the flush. 5. **Keep the iron directed into the sink through the cycle.** The pump can make noise and the soleplate releases hot water and steam. This is how the flush carries material out of the iron. Wait for the audible end signal and for the discharge to finish. 6. **Unplug the appliance** and rest the iron safely while it cools. The end of the cycle is not a signal that the soleplate has cooled. If you cannot hold the iron over the sink and reach the control without straining the hose, change the position of the base before starting. The optional holder in the shared instructions is shown with an asterisk. Follow the hand-held-over-sink setup for this configuration and keep the base dry. ## Tell a cleaning flush from a fault A noisy pump and a large release of water from the soleplate can be normal during the Anti Calc cycle. After the cycle, consider what you see and where it is coming from. Condensation underneath a board after a long ironing session differs from water appearing at the base unit or around the hose. If the appliance is visibly damaged or water or steam escapes from somewhere other than the intended outlet, stop using it and contact Tefal. If Anti Calc still flashes and the flush did not start, check the tank is filled and fully seated, the appliance is on and you are holding the correct button for three seconds. The three seconds are the button hold. Tefal shows the end of the flush with a sound and the indicator no longer lit. Allow the appliance to finish before judging whether it has cleared the reminder. If you only heard the initial sound while pressing the button, wait and watch the soleplate from a safe position for the separate completion signal. If you cannot complete the documented cycle or it ends but the fault persists, check Tefal support with the full model code. Our [steam generator troubleshooting guide]() covers checks for low steam when the cleaning indicator is clear. ## Clean the outside only after the iron has cooled The quick-start sheet separates scale flushing from wiping the soleplate. For the wipe, it shows switching off, unplugging and giving the appliance **two hours** to cool. Wipe the cool surface with a soft damp cloth. Keep abrasive pads, detergent and chemical descalers away from the soleplate. Avoid running water over the iron or base. Brown marks during ironing can have several causes. Tefal flags water additives and residue from laundry as well as maintenance concerns. Check whether the marks came from the steam holes or from material already on the surface, then follow the appropriate manufacturer instructions. The flush cleans the steam path from within. Use the separate cool wipe for residue you can see on the metal surface. If you put descaler or another additive in the tank and now see brown streaks, Tefal’s support advises contacting an approved service centre. ## Refill with the water Tefal specifies Tefal says this appliance is designed for untreated tap water. If your water is very hard, it specifies equal parts untreated tap water and distilled water. Follow that model-specific mix rather than using water saved from a tumble dryer or adding a fragrance. If you are unsure about your supply, look up its hardness with your water provider and check the [water guide for irons and steamers]() for the differences between water types. ## The model covered here The SV8022G0 has a removable 1.8 L tank and uses the Anti Calc flush described above. If you are choosing a replacement, use the [steam generator iron guide]() to compare how the tank and maintenance arrangements differ.

Tefal identifies the exact UK SV8022G0 as a scale-draining-cycle model. Follow the powered flush section of its shared quick-start sheet. The removable collector shown in the sheet applies to other configurations. ### Why is my Tefal Express Airglide flashing and beeping? Check which light is flashing. The Anti Calc light with beeps is the reminder to run the scale-draining cycle. A water tank or mode indicator has a different meaning. Use the labelled Anti Calc button for the flush. ### How long do I hold Anti Calc on the SV8022G0? Hold the flashing Anti Calc button for three seconds while the iron is positioned over the sink. That is the start command. Wait for the end signal before you take the iron away or unplug the appliance. ### Is it normal for water and steam to come out during descaling? Yes. The cycle flushes water through the soleplate and runs the pump. Aim the hot discharge into the sink. Steam or water escaping from the base, cord area or hose is a different problem and calls for service. ### Can I add vinegar or a descaling liquid to the Tefal tank? Tefal excludes chemical descalers and water additives. Fill with the plain water Tefal permits and let the built-in scale-draining cycle do the cleaning. ### How long should I wait before wiping the Tefal soleplate? Tefal’s quick-start sheet shows a two-hour cooling wait with the appliance unplugged before wiping the soleplate. The wipe is a separate job after the powered flush. Use a soft damp cloth. **Everyday Garment Care** We research manufacturer instructions and product specifications to explain practical garment care and equipment choices.
