Choose what you notice. These are the issues covered by your appliance guide.
Check the coffee-temperature setting.
Increase the coffee temperature in the settings.
Has some time passed since the last coffee?
Run Rinsing, or Settings → Maintenance → Rinsing, to heat the spouts. To preheat cups with hot water, discard that water and dry the cups carefully before use.
Is one or both spouts failing to deliver?
Does the display say the grind is too fine?
Check that the water tank is properly inserted.
If the warning remains, ask AEG for the grind-adjustment instructions for your model before turning the dial. Contact support
Is the machine still in Ready to use mode?
Hold On/Stand-by C1 for three seconds before removing the brewing unit. Do not force it.
Check the milk-container lid, froth dial and connection nozzle.
Check the milk type and temperature.
Try skimmed or semi-skimmed milk at refrigerator temperature, about 5°C. If needed, try another brand.
Check the dial on the milk-container lid.
Choose more froth for cappuccino or frothed hot milk, less for latte macchiato, and no froth for caffe latte or plain hot milk.
Check the mains connection and side main switch A1.
Connect the machine to its mains socket and turn on A1. If the cable is damaged or a fault remains, switch off, unplug and contact authorised service.
Does the message remain after cleaning?
If the error remains after cleaning, contact AEG Customer Services. Do not attempt internal repairs. Contact support
Has the machine recently been ready for use or switched off?
Small noises or puffs can be normal. Empty the drip tray to reduce them.
When coffee does not leave a spout
If one or both coffee spouts are blocked, clear the openings and rinse.
Clear the blocked spout openings with a toothpick.
Select Rinsing, or Settings → Maintenance → Rinsing, and run the programme.
When a third rinse is requested
A third rinse can be requested if the tank was not filled to MAX during the first two rinses.
Empty the drip tray to prevent overflow, then follow the display to complete the additional rinse.
