Milk frother does not produce foam; only hot milk or weak steam comes out.

Safety first: Unplug the machine and allow the steam system to cool before disassembling the frother.

• Clean frother components: Disassemble the milk frother nozzle and soak parts in warm water with a little dish soap. Use a fine brush to clean air holes.
• Check air intake: Ensure the small air hole on the frother is not blocked by dried milk.
• Use cold milk: Use fresh, cold milk (3–3.5% fat) for best foam.
• Descale steam circuit: Run a descaling cycle focusing on the steam function to restore proper steam pressure.
