DESCALING
Why descaling
Tap water contains minerals such as Calcium and Magnesium. Heating this water results in scale
deposits on the thermostat and the heating element of the sous vide machine. As a result the heater
may not work efficiently and the water pump may get blocked. The Wartmann® sous vide device
should therefore be descaled regularly. The frequency with which you need descaling depends on the
hardness of your tap water. We recommend to descale the Wartmann® sous vide device after every
100 hours, or after every 20 times, of use.
Tools
To descale the Wartmann® sous vide device you will need a suited descaling agent. You may use a food
save (white) vinegar or citric acid as a descaling agent. Check the recommended temperature for your
descaling agent before usage.
Descaling process
Fill the water basin with water just up to the “Max” indication, leaving enough space to add the
descaling agent. Add the descaling agent. For vinegar, add 15 grams of vinegar. Wear protective
clothing when working with chemicals, use rubber gloves and safety glasses. Rinse immediately with
clean water if undiluted chemicals get into your eyes; if necessary contact your doctor.
Plug the power cord into the power socket and switch the Wartmann® sous vide device to standby.
Set the duration at 3 hours and the temperature at 80
℃
(176 F).
Press ]> to start the descaling process. After 3 hours you will hear a beep tone.
Press ]> to switch the Wartmann® sous vide device in standby. Switch the Wartmann® sous vide device
off and remove the power cord from the power socket.
Check the device for any signs of remaining scale. Repeat the above cleaning cycle if scale is still
present; if necessary add more descaling agent.
If there are no more signs of scale then please a bucket under the drainage tap and drain the water
basin. Rinse the water basin and accessories with clean water.
If the water filters at the bottom of the water basin are blocked, then they can be unscrewed, removed
and cleaned. Do not forget to screw the water filters back in place.
