MAINTENANCE:

Cleaning

It is important for the Machine and its accessories to be kept clean after use.

• Unplug the coffee maker and allow it to cool.
• Wipe all external surfaces, including the hotplate, with a damp cloth and dry thoroughly.
• The glass jug, pots, and filter basket should be washed in warm, soapy water, then rinsed and dried thoroughly.

De-sediments

If you operate in a hard water area, we recommend descaling at regular intervals, e.g., every 2–3 months or as required. If the brewing cycle takes longer than usual or the steam condition is higher than normal, it is a signal that descaling is necessary.

• Add 300 ml fresh lemon juice or condensed lemon juice to 1 Liter of warm water (below 50°C).
• Slide the Filter Pan and place an empty decanter or receptacle at the correct position under the Filter Pan.
• Pour the solution of lemon juice into the Water Reservoir and turn the switch ON.
• Some hot water will drop into the decanter or receptacle until the solution of lemon juice pushes out the water remaining in the Machine. When some solution of lemon juice drops into the decanter or receptacle, then turn the switch OFF.
• Wait for 5–6 minutes to enable the rest of the solution to run through with sediments, then turn the switch ON again.
• When the indicator lights off, set the switch OFF and flush the solution away.
• Since some solution will remain in the Machine, we must run the brewing process several times until there is no more smell of lemon juice in the hot water flowing out from the Machine.
• The machine is ready for service again.

Re-setting

In case the brew cycle fails to operate, switch the appliance off and unplug it from the power supply. Remove the rear cover and check to see if you can press the button down on the side of the boiler. If the button is pressed down and clicks, then descale the unit before the next operation. If the problem persists, then contact the Helpline.

《★》In case the thermostat reaction causes lime build-up, the user must press down and click, then descale the unit before the next operation. The descaling process is as below. If the problem persists, then contact the Helpline to descale. We recommend you use an appropriate…

De-scale

In areas of the water boiler, hard water will cause chalk and limestone to accumulate when the machine is used. To keep the Machine in the best condition and ensure each coffee brewing results in the best taste, we recommend that if the Machine has been successively brewed for 200 times or used for 6 months, a descaling operation be carried out as follows:

•  Add 300 ml of fresh lemon juice or condensed lemon juice to 1 liter of water.
• Slide the Filter Pan into position.
• Place an empty Decanter at the correct position under the Filter Pan.
• Pour the lemon juice solution into the Water Reservoir.
• Turn the switch ON.
• Some hot water will drop into the jug until the solution of lemon juice pushes out the water remaining inside the Machine, and there is some solution of lemon juice starting to drop into the jug, then turn the switch OFF.
• Wait for 5–6 minutes to enable the rest of the solution to run through with sediments, then turn the switch ON again.
• When the solution of lemon juice is no longer dripping out, set the switch OFF and flush the solution away.
• Since some lemon juice solution will remain in the Machine, please run the brewing process several times until there is no more taste and smell of lemon juice in the hot water flowing out from the Machine.
