3.2 Descaling Instruction

Regular descaling is essential for maintaining your machine's performance. Three descaling methods are available: descaling powder, descaling tablets, or liquid descaler.

1. Prepare Solution: Open one packet of descaling agent. Empty one sachet into 1.2 liters of water and stir to dissolve. Leave to stand for 5 minutes (fully dissolve the descaler).
2. Initiate Descaling: Turn on the machine and ensure it stays under standby mode. Place a container under the brewing head and steam tube. Add the descaling solution to the water tank. Hold and press the GRIND, SINGLE-cup, and DOUBLE-cup buttons for 5 seconds to start the descaling process.
3. Descaling Cycle 1: Turn the knob to the STEAM position. The steam indicator will flash. Hot water will go through from the brewing head and steam tube. When hot water dispensing is stopped, turn the knob to the off position. The steam and hot water indicators will illuminate solidly.
4. Descaling Cycle 2: Clean the water tank and empty the containers. Then fill the water tank with fresh water. Turn the knob to the HOT WATER position. The hot water indicator will flash. Hot water will go through from the brewing head and steam tube. When hot water dispensing is stopped, the power indicator stops flashing. Turn the knob to the off position. The descaling cycles will be cleared, and the machine will return to standby state.

4. Troubleshooting

• Why does the drip tray release steam and discharge water automatically?

  This is normal. After the steam function is used, the machine needs to cool down and relieve pressure. You need to wait 20 seconds to continue making coffee.
• Why isn't the coffee hot?

  You can use the hot water function of the steam wand to preheat your cup, or place the cup on top of the machine to warm it before brewing coffee.

• Why is the steam not stable?

  After preheating the steam, you need to release the steam for a few seconds first to stabilize it before proceeding to the next step.

• Why does steam not come out after preheating steam?

  The steam wand may be blocked. Take out the cleaning pin from the tool box in the drip tray. Use the thicker end to clean the steam wand. Also, you can remove the outer tube and clean the inner tube in the same way.
• Why is the grind indicator flashing?

  The bean hopper is not installed properly. Align the bean hopper guide with the red grinder interlock and insert the hopper, then clockwise rotate it to install.

• Why do the four indicators flash quickly?

  This means there is a water shortage in the water tank. You need to add water and restart the machine. Another reason could be that the coffee got over-extracted due to too much pressure.

• Why doesn't the coffee come out?

  The filter may be blocked; please unclog the filter with the thinner pin. If the grind size is too small, the powder is too fine to discharge the coffee. You can increase the grind size, and the coffee powder will be slightly coarser. Continue to observe the flow of coffee and make adjustments at any time. It is also considered that because the powder is too little or the tamping power is too light, then you can increase the amount of powder or the tamping power, or replace the single wall filter with a double wall filter.
• Why does coffee have no oil?

  The grind size being too large will make the powder too coarse like white granulated sugar, and the coffee may lack oil. At this time, you can decrease the grind size to make the powder slightly finer.
