Descaling
,
To prevent the risk of damage
only use the descaling agent
supplied with the appliance (see
"Accessories supplied").
Descaling must be carried out on a
cold appliance to prevent harmful
vapours forming.
The descaling agent is caustic.
Avoid contact with the skin and do
not inhale the vapours.
If you do come into contact with
descaling agent it should be rinsed
off immediately with plenty of fresh
water. In the event of an adverse
reaction or if it has been inhaled or
ingested, seek medical help.
Replace the lid securely after use
and keep out of the reach of
children.
Do not spill descaling agent on
metal surfaces. This could cause
marks. Any spillages should be
wiped away immediately.
The appliance will alert you after a
certain number of operating hours that
the steam generator needs to be
descaled. When the appliance is
switched on the k symbol, the Descale
programme symbol k and the number
10 will appear in the
programme/temperature display.
The number indicates that the
appliance can be used a further 10
times before it locks out. If the
appliance is not descaled immediately,
a
9 will appear in the display the next
time the appliance is switched on, and
so on.
The appliance will then lock and it must
be descaled before it can be used
again. We recommend that you descale
the appliance before it locks out.
The descaling process can only be
stopped by switching off the appliance.
If the appliance is switched back on,
after interrupting it, a rinse cycle will be
carried out automatically (see "Problem
solving guide").
