down (►7.7).
Turn off the mains electrical supply before
cleaning the machine.
Interior cleaning 8.2.1
The interior of the machine should be
cleaned after each service when the
machine is drained down.
As a minimum Classeq recommends the
following are checked and cleaned (►3.1):
Remove and clean top and
bottom rinse and wash arms.
Remove and clean primary filters
Remove and clean secondary
filters.
Clean interior of the wash tank
with a sponge and/or brush for all
apertures and outlets.
Clean around door hinge
Use a trigger spray bottle with a
jet nozzle to spray the ball in the
anti-syphon device.10
If required apply food grade
grease to the door ball catch.
Ensure all arms and filters are refitted to the
machine before turning it on.
Exterior cleaning 8.2.2
Wipe the exterior of the machine with a
damp (NOT WET) sponge.
Once dry, clean using a STAINLESS
STEEL cleaning agent.
8.3 Lime scale
For best results ensure your machine is
operated with soft water (≤3°dH).
If your machine is connected to an external
softener, ensure this is routinely
‘regenerated’ as per the instruction of the
water softener.
If your machine 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 machine could be
damaged. For more information on hard
water refer to Appendix A (►11).
8.2 Daily cleaning
It is recommended that the machine is
cleaned daily to ensure good hygiene in the
machine.

follow the troubleshooting tips before
requesting a service callout. The service
support number can be found in the ‘Useful
contact details’ section (►16):
9.1 Machine will not fill
Your machine operates a pulse fill function,
this means that it will fill the rinse boiler,
heat this to a pre-set temperature then
transfer this water to the wash tank. During
the fill stage the heating indicator will flash
amber.
If your machine has been in this state for
more than a specific time the error indicator
will illuminate. Check the items below
before requesting a service callout:

to your machine.
Water supply is turned on.
Water supply hose has not been
trapped or kinked.
Check that the site water supply
has not been interrupted.
Check the machine is turned on.
Check the door is closed.
9.2 Machine will not turn on
Machine is connected to a mains
power supply.
Check power supply switch is
turned on.
On 13A machines first check and
replace the fuse in the plug,
ensuring that the correct rating is
used.
On all ratings of machine check
and reset circuit breaker in the
site fuse board.
If the fuse or breaker continues to
trip, do not reset and request a
service callout.
9.3 Machine fills slowly
Check water supply is turned fully
on.
Check water supply hose has not
been trapped or kinked.
Check that the site water supply
has not been interrupted.
Check site pressure is adequate
(►4.3.2).
9.4 Machine over filling
If your machine is over filling during the fill
cycle attempt to drain the machine (►7.7)
and refill before isolating the machine and
requesting a service callout.
9.5 Machine does not heat
Machine is turned on (►9.2).
Machine able to fill (►9.1).
Enough time has been allowed
for the machine to fill and heat
(►7.3).
9.6 Excessive foam in wash tank
Chemicals are commercial ware
washer grade.
Chemical dosage is correct.
Check wash tank has fully
heated.
9.7 Cycle does not start
Your machine has a heat interlock that will
delay the start of the wash cycle until all
criteria have been met. When the criteria
have been met the heat indicator lamp will
illuminate green and the cycle should start.
If this is not the case please check the
below items before requesting a service
callout.
Machine is on.
Enough time has been allowed
for the machine to fill and heat
(►7.3).
Wash tank is full of water.
Page 22
Page 21
9.8 Cycle runs for a long time
Your machine has a heat interlock to
ensure that the rinse is in accordance with
environmental health requirements. This
will extend the wash cycle if the rinse boiler
has not achieved the required temperature.
9.9 Machine does not rinse
If your machine runs through a full cycle,
but does not rinse, you will need to request
a service call to identify the root cause of
the problem.
9.10 Machine over flowing
Drain/stand pipe is correct for the
machine (►4.3.3).
Site waste is not blocked.
Machine waste hose is not kinked
or blocked.

rinse aid and detergent bottles
and the bottle weights and tubes
are correctly positioned.
Chemical dosing set to the
correct concentration levels
(►6.3).
Machine is regularly cleaned
(►8.2).
Water softener regenerated
(external) or salt reservoir full
(internal)
Glasses may need to be
renovated.
9.13 Machine will not turn off
Isolate the machine before requesting a
service callout.
9.12 Machine does not drain
The drain/stand pipe is correct for
the machine (►4.3.3).

used for the machine type
(►7.7).
Page 23
Page 22
Warning
If the machine is being
drained immediately after
use, water draining from the
‘Boiler drainage hose’ may
reach up to 95°C.
RECYCLING If you are
recycling or disposing of
your machine, you must
ensure this is done in
accordance with local and
national regulations.
10. Decommissioning
If for any reason you require to remove or
decommission your machine 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 machine is fully
drained (►7.7). 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 machine from the
mains electrical supply:
Machines with an electrical plug,
always pull the plug. Never pull the
cord itself.
Once the electrical supply has been
disconnected, ensure the equipotential
wire is removed from the stud at the
rear of the machine.
Turn off the water supply to the
machine 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
3mm hex key.
Now locate the ‘Boiler drainage hose’
as shown. Ensure this protrudes from
the front of the machine and you have
a container large enough to hold 8
litres of water.
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
machine to prevent tripping hazards.
The machine is now ready to be
removed.
Machines 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.

11. Appendix A – 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 machine. These
particles are formed most quickly at the hottest part of the machine – 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 machine.
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 machine 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 machine, 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. As a
guide refer to the map in Appendix B (►12).
