Descaling
Regular descaling prolongs the life of the appliance and guarantees optimal brewing results and a
constant brewing time for a long time.
In case of normal use (two full jugs of coffee every day), descale the appliance:
- 2 or 3 times a year if you use soft water (up to 18dH);
- 4 or 5 times a year if you use hard water (over 18dH).
Contact your local water board for information about the water hardness in your area.
You can use white vinegar with 4% acetic acid or a liquid descaler to descale the coffeemaker.
Note: If the appliance starts to produce more steam, this can be an indication that scale is building up.
Never use vinegar with an acetic acid content of 8% or more, natural vinegar, powder descalers
or tablet descalers to descale the appliance, as this may cause damage.
Descaling takes approx. 30 to 60 minutes.
1 Fill the water tank with one litre of white vinegar (4% acetic acid) (Fig. 16).
Note: Do not put a filter and ground coffee in the filter holder.
Note: You can also use an appropriate liquid descaler. In this case, follow the instructions on the package
of the descaler.
2 Press the on/off switch to switch on the appliance and let it complete the brewing cycle (see
chapter 'Using the appliance') (Fig. 9).
3 Empty the jug over a sink (Fig. 17).
Note: For extra through descaling and to make sure that there is no scale left in the appliance, repeat
steps 1 to 3.
4 Let the appliance complete two more brewing cycles with fresh cold water to remove any
vinegar/descaler and scale residues (Fig. 18).
5 Clean the jug and the filter holder (see chapter 'Cleaning').
replacement
You can order a new jug from your local Philips dealer or a Philips service centre under type
number HD7989/20 (black) and HD7989/00 (grey).
Environment
- Do not throw away the appliance with the normal household waste at the end of its life, but
hand it in at an official collection point for recycling. By doing this, you help to preserve the
environment (Fig. 19).
