De-scaling the Appliance

It is recommended that the appliance be de-scaled regularly. Excessive scale deposits may
become difficult to remove with some de-scaling products.
• To de-scale the appliance, isolate the appliance from the water and electricity supply.
• Allow the water to cool to prevent possible injury when removing parts.
• Remove the outer and inner lids.
• Add the de-scaling compound, a little at a time, to the cooled water. Some de-scaling
compounds may cause hot water to erupt. It is advisable to follow the instructions of the
manufacturers.
• Replace the inner and outer lids of the appliance.
• Turn on the water and electricity supply.
• Allow the appliance to heat and run in standby mode for approximately 30 minutes, after
which, isolate the services and allow the water to cool.
• Remove the lid system and inspect the tank for scale deposits. In the case of severe scale
deposits it may be necessary to repeat the de-scaling process.
• On completion of successful de-scaling, evacuate the tank via the faucet. To complete the
evacuation of the tank, move, if possible, the appliance so that the leading edge of the
appliance over hangs the work surface not exceeding 30mm. Place a suitable container
directly below the appliance over hang to capture the discharge from the tank. If it is not
possible to move the appliance on the work surface the remaining contents of the tank can be
drained into the spillage tray. Note. The spillage tray has a small limited capacity. Where the
appliance is wall mounted the container can be placed beneath the appliance.
• Examine the level sensor housings for scale build up and other deposits, clean as necessary.
Failure to do so may incur problems with tracking from sensor housing to the tank wall
thereby giving false signals to the circuit board and ultimately cause failure of the appliance.
• Insert a flat bladed screwdriver into the drain valve screw and rotate anti-clockwise to loosen
the screw. Continue to rotate the screw anti-clockwise until a steady flow is observed from
the valve.
• Evacuate the tank completely and close the valve by rotating the valve screw clockwise.
Ensure the valve screw is fully home.
• It will be necessary to purge the tank, turn on the water and electricity supply and allow the
appliance to fill. Do not fill the tank manually with water as spillage may damage the
electrical components of the appliance and therefore invalidate the warranty.
• Drain the tank as described above and refill the appliance.
• If the water is free of tainting that may be caused by the use of some de-scaling compounds
then the appliance is ready for use.
