You will need:

  1. Water
  2. Descaler: We recommend using Durgol. You can purchase it here:
    1. Customers in the United States of America:
    1. Customers in Canada:
  3. Two measuring cups or water reservoirs. For your own safety, please use reservoirs with a handle to help prevent spilling hot water
    1. One large reservoir that holds at least 2 liters / 8.5 cups, and
    2. One small reservoir that holds at least at least 300 mL / 1.5 cups
  1. Preparation
    1. Fill the water tank to the “Max” mark with the descaling solution/water mixture. We recommend you use a 50/50 mixture of Durgol and water.
    2. Place the tank back on the machine. Ensure the tank is properly seated on the machine.
    3. Place the empty large water reservoir under the steam valve, and the empty small one under the grouphead.
    4. Check that the steam knob is in the (Off) position.
    5. Ensure the espresso maker is plugged in and that it remains so during the entire descaling process. If for some reason the power is interrupted, the process must be started over.
    6. Power on the Espresso maker. Immediately after powering it on the one and two cup lights will blink indicating the machine is warming up. This will continue for about 1 minute, after which they will turn solid. The espresso maker is now in standby.

  2. Descale Cycle:  Takes approximately 15-20 minutes.
    Enter the descale program by doing the following:
    1. With the machine in standby, hold the steam button down for 10 seconds until the lights begin to blink in sequence.
    2. Rotate the steam valve towards you to the  (ON) position.
    3. Press the steam button. You will know you are in the descale program if the steam button is flashing orange and the machine begins to pump water quickly, slowing down shortly into the cycle.
    4. After two minutes have passed, in order to run some descaler through the grouphead, rotate the steam valve back to the (Off) position for approximately 2 minutes. After this time rotate the steam valve towards you to the  (On) position.
    5. Once the water in the tank has run out, the machine will stop pumping automatically. The pump will be very noisy at the very end of this process for a short period of time because the pump is starved of water. This is normal.
    6. After the pump has stopped pumping, empty both the water reservoirs.
      WARNING: The water in the reservoirs is hot. Be careful not to spill.
    7. At this point the steam button will still be lit up orange.

  3. First Rinse: Takes approximately 5 minutes.
    1. Place the empty large reservoir back under the steam spout, and the empty small reservoir back under the grouphead.
    2. Remove the water tank and refill it with just water to the “Max” mark.
    3. Place the water tank back on the espresso maker, ensuring it is properly seated.
    4. Press the steam button once and the first rinse cycle will begin.
    5. In order to rinse the grouphead, rotate the steam knob towards you to the  (On) position.
    6. After 1 minute has passed rotate the handle back.
    7. As before, the machine will run until it is out of water, after which it will stop the pump.
    8. At this point the steam button will still be lit up orange.

  4. Subsequent Rinses: Repeat the actions in step 3 (First Rinse) as many times as is needed. The espresso maker will generally run at least two rinses after the descaling solution is run through, however it is possible that more rinses will be needed depending on water hardness and time since last descale. When enough rinses have been completed, the orange light on the steam button will turn off indicating that the machine is fully descaled. At this point the user should turn the steam valve to the  (Off) position. Once the one cup and two cups are lit up solid the espresso maker is ready to be used.
