7.2 Descaling

During operation scale will form in the machine.

Therefore the machine needs to be descaled

regularly to guarantee the lowest energy

consumption and proper functioning.

When to descale?

Depending on the use and hardness of the water, we

advise you to have the WKI descaled by a service

technician every 5 or 6 months.

Depending on the frequency of usage and the

hardness of the water, we advise you to inspect the

appliance regularly for scale formation.

Remove the cover of the water boiler regularly;

If there is loose scale grit on the bottom, or if there

is severe scale formation on the walls, then the unit

needs to be descaled.

Descaling procedure for the service engineer:

1. Switch off the appliance and remove the plug

from the socket.

2. Remove the bottom plate by unscrewing the

fastening bolt in the middle of the plate.

3. Once the hexagonal plug has been removed

from the red drain tap, the drain tap can be used

to completely drain the water boiler.

Any loose boiler scale will then be removed.

4. Close the red drain tap, replace the hexagonal

plug and bottom plate (for safety reasons).

5. Switch the water boiler on again, allow it to

fill until all scale deposit has been completely

submerged.

6. Switch on the heating system and heat the water

to a temperature of approx. 60°C.

7. Read the warnings and other instructions

indicated on the Animo scale remover.

WARNING

• To descale the WKI the appliance needs to be

opened and partly disassembled. As a result

components are opened up that have a high

voltage and are not covered. Always discon nect

before opening the appliance!

WARNING

• Since the drain tap is located in the electrical

part of the water boiler, users are advised (for

safety reasons) not to descale the hot water

boiler themselves!

8. Add the scale remover to the heated water.

Please note:

once the scale remover has been added, the

water will start to foam. In extreme cases, where

too much scale remover has been used, the

foam may flow over the edge of the water boiler!

9. When no more scale remover is required

(no foaming occurs when more scale remover is

added), drain the water boiler via the tap.

In the event of obstinate boiler scale, repeat

steps 5-9.

10. Repeat steps 1-4 in order to drain the water

boiler.

11. Once all boiler scale has been removed, rinse

the water boiler thoroughly with clean water, not

forgetting to also rinse the tap.

12. The water boiler is now ready for use again.

8. Dry-boil protection

This appliance is equipped with a dry-boil protection.

This protection triggers if the heating element

overheats owing to a fault. Once the fault has been

resolved, the dry-boil protection can be reset at the

left side of the appliance (fig 1I). The most common

cause of the dry-boil protection being triggered is not

descaling the heating system in time.

If the heating system does not switch back on,

proceed as follows:

1. Allow the appliance to cool down.

2. Unscrew the protective cap.

3. Press the button which is now visible and firmly

screw the protective cap back on.

If the dry-boil protection triggers owing to increased

scale deposits, descale the appliance.

See chapter 7.2. Consult your dealer if the fault was

caused by a problem other than the dry-boil

protection being triggered.
