Capresso coffee maker with built-in grinder displays E8 and stops grinding mid-cycle.

Safety first: Unplug the unit and allow it to cool for at least 20–30 minutes before further use.

Steps:

• Let the grinder cool: Overheat protection often resets automatically after the motor cools down.
• Clean grinder path: Empty the hopper, remove the upper burr (if applicable), and thoroughly clean the burrs and chute with a brush. Avoid water on metal burrs unless the manual explicitly allows it.
• Adjust grind setting: Set the grind to a slightly coarser setting to reduce load on the motor.
• Use appropriate beans: Avoid extremely oily beans, which can gum up the burrs. Mix with drier beans or switch to a less oily roast.
• Test again: After cleaning and cooling, plug in and run a short grind cycle. If E8 returns quickly, the motor or thermal protector may be failing and should be replaced.
