1. Reduced Water Output

• Symptom: The machine dispenses less coffee than selected, e.g., set for 6 cups but only dispenses 4 cups.
• Possible Cause: Lime scale buildup in the heating tube can cause premature shutdown.
• Solution:
  • Prepare a descaling solution with 10 cups of water and 20 grams of descaling agent, then pour it into the water reservoir.
  • Press “GRIND OFF” and then “ON/OFF” to start brewing. When the water level reaches 2 cups, press “ON/OFF” to stop.
  • Wait 60 minutes, then press “ON/OFF” to brew the remaining water.
  • Repeat steps 1-3 three times and check if the brewing is normal.
  • If still unsuccessful, repeat steps 1-2, let it sit for 3 days, then complete brewing.
  • Fill with clean water to the max line and brew all water, repeating at least 3 times.

2. Steam Leakage

• Possible Cause: Lime scale blockage causing prolonged heating time.
• Solution:
  • Prepare a solution with 10 cups of water and 100 grams of descaling agent and pour into the reservoir.
  • Press “GRIND OFF” and then “ON/OFF” to start brewing. When the water level reaches 2 cups, press “ON/OFF” to stop.
  • Wait 60 minutes, then press “ON/OFF” to brew the remaining water.
  • Repeat steps 1-3 three times to check for normal brewing.
  • If unsuccessful, let the machine sit for 5 days with the solution, then complete brewing.

3. No Heating or Water Flow

• Possible Cause: Likely a blown fuse
• Steps for Handling:
  • Contact customer services and provide:
    • Order number or screenshot
    • Video following these steps:
      • Fill the water tank.
      • Plug in, press “GRIND OFF,” then “ON/OFF” to brew.
      • After 3 minutes, check for steam or water flow.
      • Confirm if the bottom heating plate is warming up.

4. Coffee Not Hot Enough

• Explanation: Drip coffee makers heat water to around 92°C (198°F) for brewing, yielding coffee at about 70-77°C (158-170°F). The machine can keep coffee warm for up to 2 hours at around 60°C (140°F), though less coffee in the pot will cool faster. For better temperature retention, drink promptly after brewing or brew in batches.

5. Code 660 (Codes Starting with "6" Followed by Multiples of 30)

• Meaning of Code: Codes beginning with "6" refer to the brewing function, and numbers in multiples of 30 indicate usage frequency. This code signals that the machine has reached a set number of uses and requires a cleaning. This code is a reminder and does not impact normal operation.
• Solution Steps

1. 1. Prepare a Descaling Solution:
      • Use a descaling agent.
      • Fill the glass carafe with 10 cups of water, add 33 grams of descaler, mix well, and pour into the water reservoir.
   2. Start Descaling:
      • Place the carafe on the warming plate, plug in the machine, and ensure the display lights up.
      • Press “GRIND OFF” (the blue “GRIND OFF” indicator should light up) and then “ON/OFF” to begin brewing.
      • When the water level in the reservoir reaches 2 cups, press “ON/OFF” to stop brewing.
      • Wait 60 minutes.
      • Press “ON/OFF” again to brew the remaining 2 cups of water.
      • Wait for the machine to beep three times and for the symbol to disappear.
   3. Flush with Clean Water:
      • Empty the carafe and refill it with 10 cups of clean water. Pour this water into the reservoir.
      • Place the carafe back on the warming plate.
      • Press “GRIND OFF” and “ON/OFF” to start brewing again.
      • Repeat these steps until any descaling solution residue is cleared.
   4. Clean Removable Parts:
      • After brewing, press the filter basket release button, open the swing filter basket, and remove and clean the drip-stop filter insert, permanent filter, and filter ring with water.
      • Reassemble all parts after drying, close the filter basket, and replace the carafe.
