What You’ll Need

Before you start cleaning, gather the following supplies:

• Espresso machine cleaning tablets
• Descaling solution (if applicable)
• Microfiber cloths or paper towels
• Brush or toothpick
• Small bowl or cup
• Clean water

Step-by-Step Cleaning Guide

1. Daily Cleaning

• Empty and clean the portafilter: Remove the portafilter and knock out any spent coffee grounds. Rinse the portafilter and basket thoroughly with hot water.
• Wipe down the machine: Wipe down the exterior of the machine, including the drip tray, with a damp microfiber cloth.

2. Weekly Cleaning

• Backflush the group head: Insert a cleaning tablet into the portafilter and lock it into the group head. Run hot water through the machine for about 10 seconds, then stop. Wait for 30 seconds and repeat the process several times. This helps remove coffee oils and residue from the group head.
• Clean the steam wand: Dip the steam wand into a small bowl of hot water and turn on the steam. Allow steam to run through the wand for about 10 seconds to remove any milk residue.
• Wipe down the machine: Wipe down the exterior of the machine and the portafilter with a damp microfiber cloth.

3. Monthly Cleaning

• Descale the machine: If your machine is prone to scale buildup, use a commercial descaling solution according to the manufacturer’s instructions. This will remove mineral deposits from the boiler and other internal components.
• Clean the water tank: Remove the water tank and rinse it thoroughly with hot water. Clean the inside of the tank with a microfiber cloth or brush if necessary.
• Clean the shower screen: Remove the shower screen from the group head and soak it in a cleaning solution for 10-15 minutes. Use a brush or toothpick to gently remove any coffee residue or blockages.

4. Annual Cleaning

• Thorough disassembly: Most espresso machines require an annual thorough disassembly for deep cleaning. Refer to the manufacturer’s instructions for specific steps, as disassembly procedures vary depending on the model.
• Clean all components: Disassemble and clean all components, including the boiler, pump, valves, and internal tubing. Use a cleaning solution and brush to remove any scale, residue, or blockages.
• Reassemble the machine: Carefully reassemble the machine according to the manufacturer’s instructions.

Tips for Maintaining Your Espresso Machine

• Use filtered water to prevent mineral buildup.
• Clean the machine immediately after use to prevent coffee oils and residue from drying and caking on.
• Backflush the group head regularly to remove any lingering coffee residue.
• Descale the machine every 2-3 months, or more frequently if your water is hard.
