How to Run a Full Clean on Melitta SOLO Coffee Machine

If your Melitta SOLO coffee machine has started brewing weaker shots or leaving oily residue in your cup, it’s likely due to built-up coffee oils and mineral deposits you can’t reach by hand. These residues affect taste, hygiene, and machine longevity—but the solution is straightforward.

To fully clean your Melitta SOLO machine, run the integrated cleaning program every two months or after about 200 brews, or as soon as the cleaning icon lights up on the display. This 15-minute process clears out coffee oils, calcium build-up, and other residues inside the brew group and internal pathways.

What Is the Melitta SOLO Coffee Machine Cleaning Program?

The Melitta SOLO cleaning program is an automated routine designed to flush out coffee oils, mineral scale, and other hard-to-reach residues from inside the machine. It can’t be done manually and must be run using a specific button combination. This helps maintain espresso quality, prevents clogs, and extends machine life—especially important for home users brewing regularly.

When Should You Run the Full Clean Cycle?

You should run the comprehensive cleaning cycle:

• Every two months, or
• After approximately 200 coffee brews, or
• As soon as the cleaning symbol lights up on the machine’s display.

This ensures the internal components—especially the brew group and water pathways—stay free of coffee oils and mineral buildup that affect taste and performance.

Step-by-Step: How to Run the Melitta SOLO Full Cleaning Program

Follow these 14 steps exactly to complete the full cleaning cycle on your Melitta SOLO coffee machine:

1. Prepare the water tank: Open the water tank lid, lift the tank out, fill it with water to the maximum fill line, then reinsert it.
2. Start the cleaning mode: Press and hold both the single-cup button and the power button simultaneously for more than two seconds.
3. Observe the indicators: During the entire cleaning process, the cleaning icon and the water tank (drain tray) icon will flash alternately.
4. Empty containers: Remove and empty both the drain tray and the coffee grounds container. Reinsert only the drain tray (without the coffee grounds container). Place the coffee grounds container directly under the coffee outlet.
5. Automatic rinses: The machine will run two initial automatic rinse cycles, then the standby icon will light up.
6. Access the brew group: Reach into the machine’s right-side recess and pull out the cover panel. Then, rotate the red button on the brew group handle clockwise until it stops (about 75 degrees).
7. Remove the brew group: Pull the brew group straight out from the machine. Once removed, the standby icon and cleaning icon will alternate flash. Note: You can only remove the brew group during designated times to avoid damage.
8. Clean the brew group: Hold the brew group steady (do not twist or move internal parts), then rinse all sides thoroughly under running water. Let it air-dry briefly before inserting a cleaning tablet or tablet-sized cleaner inside.
9. Reinstall the brew group: Put the brew group back into the machine. Rotate the handle counterclockwise until it locks (stops moving). The cleaning icon continues to flash; the standby icon turns off and the water tank icon lights up. Replace the brew group cover.
10. Refill with fresh water: Open the water tank again, lift it out, fill it to the max line with fresh water (not necessarily purified, but clean), and reinsert the tank.
11. Start the second rinse phase: Slide the coffee outlet down fully, then press the coffee strength button. The extended cleaning process will continue for around five minutes. Water will flow from the outlet through the internal pathways into the drain tray. The drain tray icon will light up.
12. Repeat water refill and drainage: Open the water tank, fill it again to the max line with fresh water, and reinsert. Empty both the drain tray and the coffee grounds container.
13. Final rinse setup: Reinsert the drain tray without the coffee grounds container. Position the coffee grounds container under the coffee outlet. The cleaning process runs for another five minutes with water draining through the machine into the tray. The drain tray icon will light up again.
14. Complete the cycle: After the cycle finishes, empty both the drain tray and the coffee grounds container. Reinsert both. Allow the machine to warm up briefly, until the standby icon lights up—your machine is now ready for normal use.

Important Notes During the Cleaning Process

Only remove the brew group during the brief window when the icons indicate it’s safe. Do not twist or force any part of the brew group during cleaning. Always use fresh water (not espresso grounds or old water) during refills. Don’t interrupt the cycle once started.
