- limescale/scale buildup in the steam generator cutting steam output in hard-water areas

Quick check — and when it's not DIY
Before booking a repair, note the exact error code or light pattern, then try a full power cycle — unplug for 60 seconds before doing anything else. Also, check whether the error only appears during a specific cycle or setting, which narrows down the fault. If none of that changes anything, a code that returns after a power cycle means an internal sensor or board is reporting a real fault, and clearing codes without fixing the cause just masks it.
