8.3 Lime scale
For best results ensure your warewasher is
operated with soft water (≤3°dH).
If your warewasher is connected to an
external softener, ensure this is routinely
‘regenerated’ as per the instruction of the
water softener.
If your warewasher has an internal water
softener fitted ensure the salt level is
maintained as per the instructions in this
manual.
If your warewasher is operated with hard
water without the relevant water treatment,
the internal working and all water lines can
become ‘scaled’, your results will deteriorate
and the warewasher could be damaged. For
more information on hard water refer to
Appendix B (►12).
Caution
Damage to the
warewasherd caused by
lime scale will NOT be
covered by the
manufacturer’s warranty
(►Chyba! Nenalezen
zdroj odkazů.).
Page 23
8.4 Regular maintenance
Water softener salt (if fitted)
When the salt level inside the water softener
reservoir gets low the refill salt indicator will
illuminate (flash) on the display.
The salt should be replenished as soon as
possible to avoid lime scale from building up
in your warewasher.
To refill the salt reservoir follow the
instructions below:
1. Lift the hood up of the
warewasher.
2. Remove the basket ramp.
3. Open the salt reservoir cap at the
front right hand corner of the wash
tank.
4. Using the salt funnel supplied fill
the reservoir with granulated salt.
5. Wipe away any excess or spilt salt
from the cabinet and the reservoir
opening.
6. Refit the cap to the reservoir,
ensure that the cap is fitted flat
and secure.
Note: The refill salt indicator may stay
illuminated for up to 3 complete wash
cycles after filling/refilling the salt
reservoir with salt
7. Drain down the warewasher to
remove the salt water.
Warning
DO NOT run the
warewasher if there is no
salt in the salt reservoir,
as this will allow lime
scale to build up, also any
lime scale will invalidate
your warranty
DO NOT add any
chemicals, such as
detergent or rinse aid to
the reservoir. These will
cause damage to the
warewasher.
Caution
Only use granulated salt
(max. grain size 5 – 7
mm). Salt tablets are not
suitable.
If the reservoir cap is not
properly secured, water
and/or chemicals can leak
in or out of the unit
causing damage to the
warewasher.

10. Decommissioning
If for any reason you require to remove or
decommission your warewasher do so in
accordance with local and national
regulations.
As a minimum Classeq recommends the
following procedure is followed.
Prior to removing any chemicals refer to all
safety statements on chemical bottles for
dealing with any spillage.
Remove chemical tubes from the
chemical bottles, ensuring the
bottles are then capped to prevent
any further spillage.
Ensure the warewasher is fully
drained (►7.9). Once completed
remove the waste hose from the
drain standpipe; ensure any spilt
liquid is dried prior to advancing
to the next step.
Turn off the mains electrical
supply at wall / isolator / junction
box
When disconnecting your warewasher from
the mains electrical supply:
Warewashers hard wired (i.e. no plug),
this must be disconnected in
accordance with local and national
regulations; Classeq recommends this
is performed by a qualified electrician.
Once the electrical supply has been
disconnected, ensure the equipotential
wire is removed from the stud at the
rear of the warewasher.
Turn off the water supply to the
warewasher and disconnect the water
supply hose from mains water supply,
ensuring any spillage is dried prior to
moving onto next step.
Remove the front lower panel using a
8mm spanner to release two M5 hex
head screws at the bottom.
Now locate the ‘Boiler drainage hose’
as shown. Ensure this protrudes from
the front of the warewasher and you
have a container large enough to hold
8 litres of water.
Warning
If the warewasher is being
drained immediately after
use, water draining from
the ‘Boiler drainage hose’
may reach up to 95°C.
Loosen the jubilee clip and remove the
drain plug, ensuring the water flows into
the container mentioned above. Once
fully drained replace the drain plug and
retighten the jubilee clip.
Replace the front panel, and ensure all
cables and hoses are secured to the
warewasher to prevent tripping
hazards. The warewasher is now ready
to be removed.

12. Appendix B – Water hardness explained
Water hardness occurs because certain chemicals in the rocks through which it passes on its way
to the consumer are slowly dissolved into the water.
The problem shows itself in two forms. First, when hard water is heated the chemicals come out of
solution and appear as solid particles (lime scale) that are carried round the warewasher. These
particles are formed most quickly at the hottest part of the warewasher – normally the rinse element
and the rinse tank in general. This is why the rinse tank is the best place to look to judge if lime
scale is being formed in a warewasher.
Second, most commercial chemicals operate much less efficiently in hard water, and this will often
show as poor results or failure to remove tannin stains, or condensation on glasses. Tannin stains
appear to cling to the hard water film in the drink, which then clings to the surface of the cup or
saucer. With soft water this is not the case.
Some types of hard water do not produce lime scale when heated, but it will still reduce the
performance of the chemicals, as mentioned above. This is known as permanent hardness.
Temporary hardness is when the hardness can be largely removed by conversion into lime scale
by boiling.
If lime scale is produced inside a warewasher it will cause a number of maintenance problems, for
example:
Coating of element leading to slow heating and element failure
Blockage of rinse jets showing as poor results
Wear of bushes in centre boss, showing as poor results and possibly wash water passing
backwards into the rinse system.
Blockage of rinse-aid injection point in boiler.
White marks may appear on glasses, dishes and cutlery.
Dishes or cups may appear dirty even after a wash. Especially coffee or tea cups.
Discolouration of inside of warewasher, making cleaning difficult.
Blockage of hoses due to the deposit “furring up” the inside of the hose.
When lime scale is found, it must be removed with commercial De-scale, used with care in
accordance with the instructions on the product. The descale instructions in this manual should
always be followed. The rinse tank is difficult to de-scale and may require a service engineer.
Your local water board should be able to tell you if the water in your area is hard or soft.
