Perform vessel de-scaling.
What you will need: screw driver (+), wrenches, 10mm T-box wrench, container (14liters or
larger), 14 liters (3.7 gal) of diluted de-scaling liquid, and 2 liters (0.5 gal) of clean tap water.
Steps:
1. Remove the top and lateral covers.
2. Open the drain valve and release all water from the vessel. Close the drain valve afterwards.
3. Disconnect the wiring from the three water probe sensors (High, Com, Low).
4. Make sure the water tank is full or disconnect the wiring from the float switch.
5. Wear gloves and goggles and prepare descaling solution based on the instruction by the
chemical supplier.
6. Detach the water suction line from the water filter and submerge the tip into the container.
7. Detach one of the steam hoses from the steam outlet and open the steam outlet valve.
8. Turn on POWER (EMERGENCY STOP) switch then turn on STEAM switch to activate the
water pump. Fill the vessel with 14 liters (3.7 gallons) of diluted de-scaling liquid.
9. Submerge the tip of the water suction line into the container filled with 2 liters (0.5 gallons) of
clean tap water to wash out the water pump. Once water starts coming out of the steam
outlet, turn off the STEAM switch.
10. Let the machine sit for the time instructed on the de-scaling liquid label. Do not exceed the
recommended time to avoid steam vessel damage.
11. Drain the steam vessel by opening the Y-strainer drain cap and temporarily remove the
strainer to prevent scale from clogging the line.
12. To wash out the steam vessel and lines, supply clean water to the steam outlet valve until
you cannot see scale coming out of the Y-strainer.
13. Reassemble the Y-strainer and the water suction line and reconnect wires to the water probe
sensors.
