Coffee tastes bitter or burnt

Step 1 – Adjust grind and strength:

• Set the grinder one step coarser while it is running.
• Reduce the coffee strength or aroma setting by one level.

Step 2 – Adjust temperature (if available):

• In the machine menu, lower the brewing temperature setting to 'normal' or 'low'.

Step 3 – Use appropriate beans:

• Use fresh, medium-roast beans designed for espresso.
• Avoid very dark or oily beans that can taste burnt and clog the grinder.

Step 4 – Clean machine:

• Run a cleaning tablet cycle to remove rancid coffee oils from the brew path.
• Descale the machine if it has not been descaled recently; scale can cause uneven heating.
