Daily, Weekly & Monthly Coffee Machine Maintenance Guide

If you’re running a café or pulling shots at home, keeping your espresso machine and grinder in top shape is non-negotiable. Dirty machines lead to channeling, off-flavours, and equipment failure. Here’s exactly how often to clean each part and what to do — with precise timing, temperatures, and measurements from professional practice.

In short: daily clean the group heads and steam wand with water and backflush pads, weekly add 2g of cleaner per backflush and soak portafilter parts for 30 minutes, and monthly maintain the boiler by draining and toggling its valve to the 180° open position.

Daily Coffee Machine Cleaning Routine

Every day, your espresso machine builds up old coffee oils, milk residue, and mineral deposits — all of which affect shot quality and machine longevity. The daily routine takes under five minutes and prevents major buildup.

• Insert the backflush disc (also called a cleaning pad or rubber disc) into a double spouted portafilter and lock it into the group head.
• Turn the machine off.
• Hold down the 60ml brew button while powering on until the screen shows “cleaning,” then release the button to start the automatic rinse cycle.
• Take a 600ml milk pitcher, fill it with 300ml cold water, and use it to purge and heat-clean the steam wand for roughly 60 seconds.
• Wipe down and rinse the drip tray to finish.

Weekly Coffee Machine Deep Clean

Once a week, you need to go deeper. Oils and coffee particulate build up in the group head gaskets, filter baskets, and internal pathways. This weekly routine uses a small amount of espresso machine cleaner to break them down.

• Place a backflush disc into the double spouted portafilter, add 2g of espresso machine cleaning powder (about half a short bar spoon), and lock it into the group head.
• Power off the machine, then hold the 60ml brew button during startup until “cleaning” appears on screen — release the button to begin the automated cycle.
• Purge and clean the steam wand again using 300ml of cold water in a 600ml pitcher for around 60 seconds.
• Use a short bar spoon to carefully pry off the group head gasket and filter screen, then wipe the group head with a damp cloth.
• Soak all portafilter filters and screens in hot water mixed with 5g (one short bar spoon) of machine cleaner.
• Finally, clean the gasket and drip tray again.

Note: Never soak any rubber or silicone parts — like gaskets or the drip tray — in the water with cleaning powder.

Monthly Boiler Maintenance

Your espresso machine’s boiler needs occasional attention to remove built-up minerals and ensure proper heating and pressure. This is a monthly task.

1. Open the machine’s drain valve to let water out.
2. Locate the black switch beneath the electronic display panel. Turn it to the 180° open position (slow the rotation for precision; it’s a fine adjustment).
3. Important: after draining the boiler, always return the black switch to the 90° closed position.

Coffee Grinder Maintenance

Even your grinder needs regular love. Old coffee grounds left inside the bean hopper and burr chamber can go stale, affecting freshness and taste. This quick routine keeps everything running smoothly.

• Take out the bean hopper and empty any remaining beans into an airtight container. Wash the hopper thoroughly.
• Grind any leftover beans into powder, then sweep them out of the burr chamber using a brush or vacuum.

Frequently Asked Questions

How often should I backflush my espresso machine without cleaner?

You should backflush your espresso machine with just water daily to clear old coffee oils and grounds from the group head. This takes less than a minute and helps maintain shot consistency and machine health.

What temperature should I use to clean the steam wand?

Purge and clean the steam wand using approximately 300ml of cold water heated to around 60°C during the process. This helps dissolve milk residue without damaging the wand’s inner lining.

Do I need to soak the group head gasket every week?

Yes, you should soak the filter basket and screen in hot water with 5g of machine cleaner for about 30 minutes once a week. However, never soak rubber or silicone gaskets, o-rings, or the drip tray in cleaner solution.

How much espresso machine cleaner should I use per backflush?

For a weekly deep clean, use 2g of espresso machine cleaning powder — about half a short bar spoon — placed in the backflush disc before locking it into the group head.

What does the 180° and 90° positions mean for the boiler switch?

The black switch under the display controls boiler drainage. At 90°, it’s closed; at 180°, it’s fully open. Always return it to 90° after draining to prevent leaks or malfunctions.

Can I clean the grinder burrs without taking them apart?

You don’t need to disassemble the burrs for regular maintenance. Grind any remaining beans to powder, then sweep out the chamber and chute using a brush. For deeper cleaning, refer to manufacturer guidelines.
