agents, or neutralising agents. These  
may contain irritant or corrosive ingre-  
dients, acids or alkalis. On no account  
use any organic solvent, as there may

ring.  
Follow the instructions and relevant  
safety procedures carefully. Wear pro-  
tective gloves and goggles.  
programme, you could burn yourself.  
Never use an ordinary or a high  
pressure hose on or in the vicinity  
of the machine.  
Before any maintenance or repair  
work is undertaken, the machine  
must be disconnected from the mains  
supply, by switching off at the mains  
isolator, or withdrawing the mains fuse.  
Avoid inhalation of powder  
cleaners. They can cause burning  
in the mouth and throat if swallowed, or  
inhibit breathing.  
The following points should be ob-  
served to avoid damage to the ma-  
chine and the loads being cleaned.  
The water in the machine must not  
be used as drinking water.  
The standard of disinfection in the  
Disinfection programmes must be  
confirmed by the user as a routine mat-  
ter. The process should be regularly  
checked using chemical indicators,  
and bacteriologically at intervals using  
bio-indicators, with full documentation.  
Proceed according to local health auth-  
ority regulations.  
Do not sit or lean on the open door,  
or rest objects on it. This could  
cause the machine to tip and be dam-  
aged.  
Be careful when sorting items with  
sharp pointed ends and position-  
ing them in the machine that you do not  
hurt yourself or create danger for other  
operators.  
Disinfection programmes must not  
be interrupted, as this can have a  
limiting effect on the disinfection result.  
However, should an interruption be  
necessary. the complete programme  
must be repeated.  
When using this machine in the  
temperature ranges from 70 to  
95°C be especially careful not to scald  
or burn yourself. Baskets and inserts  
must first cool down. Any water which  
may remain in containers will be very  
hot and must be emptied into the wash  
cabinet.  
Only use cleaning agents formu-  
lated for special processes and ap-  
proved by Miele for use with this ma-  
chine. Use of unsuitable cleaning  
agents could adversely affect the load  
or the machine.  
After drying with the TA drying unit then  
open the door to allow the items and in-  
serts to cool down.

Warning and safety instructions  
Warning and Safety instructions  
For pre-treatment and / or cleaning  
only use low-foaming detergents  
and disinfecting agents which have  
been approved by Miele. Foam can  
have an adverse effect on the disinfec-  
tion and cleaning process.  
In critical applications where very  
stringent requirements have to be  
met, it is strongly recommended that all  
the relevant factors for the process,  
such as cleaning agent, quality of  
water are discussed with the Miele Ap-  
plication Technology specialists.  
Where a chemical additive is re-  
commended on technical applica-  
tion grounds (for example with a clean-  
ing agent), this does not imply that the  
manufacturer of the machine takes re-  
sponsibility for the effect of the chemi-  
cal on the material of the items being  
cleaned. Please be aware that changes  
in formulation, storage conditions etc,  
which may not be publicised by the  
chemical producer, can have a nega-  
tive effect on the cleaning result.  
If the cleaning result is subject to these  
particularly stringent requirements (e.g.  
chemical analysis, specialised pro-  
cesses), a regular quality control test  
should be carried out by the user to en-  
sure that required standards of cleanli-  
ness are being achieved.  
Please follow the advice on installa-  
tion in these instructions and the  
separate Installation Instructions.  
Empty any containers or utensils  
before arranging them in the ma-  
chine.  
When using cleaning agents and  
specialised products it is essential  
that the manufacturer’s instructions are  
followed. Only use the product for the  
application described by the manufac-  
turer, to avoid any material damage or  
the occurrence of strong chemical reac-  
tions such as oxyhydrogen.  
Do not allow any remains of acids  
or solvents, or chloride solutions to  
get into the wash cabinet. Similarly  
avoid any materials with a corrosive ef-  
fect.  
The presence in compounds of any sol-  
vents should be minimal, (especially  
those in hazard class A1).  
The machine is designed only for  
operation with water and additive  
cleaning agents. Organic solvents  
must not be used in the machine, as  
there is the danger under certain cir-  
cumstances of explosion. Although this  
is not the case with all organic sol-  
vents, other problems could arise with  
their use, for example damage to rub-  
ber and synthetic materials.  
Ensure that solutions or steam con-  
taining acid salts do not come into  
contact with the steel outer casing of  
the machine, to avoid any corrosion  
damage.

Warning and Safety instructions.  
The only accessories to be used  
with the special commercial ma-  
chine must be those supplied or ap-

Professional department for advice.  
Disposal of an old machine  
When disposing of an old machine  
first make it unusable. Disconnect,  
cut off the cable and any plug from the  
cable. For environmental and safety  
reasons ensure the machine is com-  
pletely drained of any residue water  
and cleaning agent. (Observe safety  
regulations and wear safety goggles  
and gloves). Make the door lock inoper-  
ative, so that children cannot acciden-  
tally shut themselves in. The simplest  
way to do this is to remove the locking  
pin (2 philips screws above the door).  
Make appropriate arrangements for the  
safe disposal of the machine. For tank  
system machines ensure that any water  
is emptied out of the tank.  
In countries where there are areas  
which may be subject to infesta-  
tion by cockroaches or other vermin,  
pay particular attention to keeping the  
machine and its surroundings in a  
clean condition at all times. Any dam-  
age which may be caused by cock-  
roaches or other vermin will not be  
covered by the machine guarantee.

properly cleaned.  
General glassware used in labora-  
tories, e.g. beakers, conical flasks, test  
tubes, etc., can be arranged in full-  
size, half or quarter inserts in top or bot-  
tom baskets. Your Miele laboratory  
dealer will advise on specific require-  
ments.  
Do not place items to be cleaned in-  
side other pieces where they may be  
concealed.  
Hollow vessels such as beakers,  
measuring cylinders, flasks, etc.  
should be inverted and placed in the  
correct inserts. A cover net can be  
used to reduce the risk of movement  
during the wash process.  
The following instructions relate only to  
basic preparation and loading of glass-  
ware.  
Petri dishes and similar should be  
placed in the correct insert with the  
soiled side facing the centre.

programme, you could burn yourself.  
Never use an ordinary or a high  
pressure hose on or in the vicinity  
of the machine.  
Before any maintenance or repair  
work is undertaken, the machine  
must be disconnected from the mains  
supply, by switching off at the mains  
isolator, or withdrawing the mains fuse.  
Avoid inhalation of powder  
cleaners. They can cause burning  
in the mouth and throat if swallowed, or  
inhibit breathing.  
The following points should be ob-  
served to avoid damage to the ma-  
chine and the loads being cleaned.  
The water in the machine must not  
be used as drinking water.  
The standard of disinfection in the  
Disinfection programmes must be  
confirmed by the user as a routine mat-  
ter. The process should be regularly  
checked using chemical indicators,  
and bacteriologically at intervals using  
bio-indicators, with full documentation.  
Proceed according to local health auth-  
ority regulations.  
Do not sit or lean on the open door,  
or rest objects on it. This could  
cause the machine to tip and be dam-  
aged.  
Be careful when sorting items with  
sharp pointed ends and position-  
ing them in the machine that you do not  
hurt yourself or create danger for other  
operators.  
Disinfection programmes must not  
be interrupted, as this can have a  
limiting effect on the disinfection result.  
However, should an interruption be  
necessary. the complete programme  
must be repeated.  
When using this machine in the  
temperature ranges from 70 to  
95°C be especially careful not to scald  
or burn yourself. Baskets and inserts  
must first cool down. Any water which  
may remain in containers will be very  
hot and must be emptied into the wash  
cabinet.  
Only use cleaning agents formu-  
lated for special processes and ap-  
proved by Miele for use with this ma-  
chine. Use of unsuitable cleaning  
agents could adversely affect the load  
or the machine.  
After drying with the TA drying unit then  
open the door to allow the items and in-  
serts to cool down.

application described by the manufac-  
turer, to avoid any material damage or  
the occurrence of strong chemical reac-  
tions such as oxyhydrogen.  
The presence in compounds of any sol-  
vents should be minimal, (especially  
those in hazard class A1).  
The machine is designed only for  
operation with water and additive  
cleaning agents. Organic solvents  
must not be used in the machine, as  
there is the danger under certain cir-  
cumstances of explosion. Although this  
is not the case with all organic sol-

their use, for example damage to rub-  
ber and synthetic materials.  
Ensure that solutions or steam con-  
taining acid salts do not come into  
contact with the steel outer casing of  
the machine, to avoid any corrosion  
damage.

Disposal of an old machine  
When disposing of an old machine  
first make it unusable. Disconnect,  
cut off the cable and any plug from the  
cable. For environmental and safety  
reasons ensure the machine is com-  
pletely drained of any residue water  
and cleaning agent. (Observe safety  
regulations and wear safety goggles  
and gloves). Make the door lock inoper-  
ative, so that children cannot acciden-  
tally shut themselves in. The simplest  
way to do this is to remove the locking  
pin (2 philips screws above the door).  
Make appropriate arrangements for the  
safe disposal of the machine. For tank  
system machines ensure that any water  
is emptied out of the tank.  
In countries where there are areas  
which may be subject to infesta-  
tion by cockroaches or other vermin,  
pay particular attention to keeping the  
machine and its surroundings in a  
clean condition at all times. Any dam-  
age which may be caused by cock-  
roaches or other vermin will not be  
covered by the machine guarantee.

hand side of the control panel comes  
on during a programme the built-in  
water softener is depleted and cannot  
supply any more softened water. It  
must therefore be reactivated with dish-  
washer salt as soon as the pro-  
gramme has finished.  
If this cannot be done immediately, and  
further batches have been washed,  
then the reactivation process must be  
carried out twice in succession.  
Only use special course grained dish-  
washer salt (granule size approx. 1-4  
mm), for reactivation, as other salts  
may contain insoluble impurities or ad-  
ditives which can impair the functioning  
of the softener.  
Filling the salt container  
The salt container holds approx. 2 kg  
salt.  
Important  
If the only reactivation salt available is  
fine grain, please consult your Miele  
service representative.  
Reactivation salt with granules larger  
than 4 mm cannot be used.  
Unscrew the filter insert from the salt  
container and remove.  
Fill the salt container with granular  
dishwasher salt and screw the filter  
insert back in place.

Open the stopcocks if previously closed.  
Close the door.  
Press I-0.  
Press the k touch pad.  
Press the "Start" h touch pad.  
Remove the bottom basket from the  
machine.  
The reactivation programme proceeds  
automatically and finishes when the indi-  
cator light k at the left hand side of the  
control panel and the "Start" indicator  
light h have gone out.  
Then:  
Switch off the machine.  
Unscrew the salt container carefully,  
so that any water pressure that has  
built up can be released. Do not use  
force. If you cannot uncrew the salt  
container by hand, contact the Miele  
Service department.  
Unscrew the plastic cap in the base  
of the wash cabinet.  
Screw the plastic lid back on the socket.  
Reposition bottom basket.  
Rinse the salt container and filter in-  
sert thoroughly.  
Turn off the stopcocks if the machine  
is not to be used again for some time.  
Important  
The water pressure (flow pressure at the  
take off point) must be at least 2.5 bar. If  
it less than this see "Programming spe-  
cial functions".  
If the flow pressure is below 2.5 bar, or  
if it fluctuates, the water softener can-  
not be reactivated in the normal way.  
After reactivation, salt remains may still  
be found in the salt container.  
To use up the salt remains and to wash  
out the water softener, the "reactivate  
softener" programme must be switched  
on again.  
Place the salt container on the reacti-  
vation socket and screw firmly into  
place.

Stopcocks with 3/4 BSP male thread  
to be provided on site. They should  
be easily accessible because the  
water supply must be turned off  
when the machine is not in use.  
The machine must be connected to  
the water supply in accordance with  
the local and national regulations,  
(NWC in GB).  
The DN 10 inlet pressure hoses are  
approximately 1.7 m long and termi-  
nate in a 3/4" female thread. On no  
account must the inlet filters be  
removed.  
The machine is constructed to com-  
ply with DVGW regulations, in such a  
way that an external non return valve  
is not required.  
The water pressure (flow rate) must  
be between 2.5 and 10 bar. If the  
water pressure is not within this  
range, the Customer Service Depart-  
ment will advise you of the measures  
to take (see also "Programming spe-  
cial functions").  
For additional protection of the sole-  
noid valve against impurities in the  
water supply, large surface area fil-  
ters are enclosed in the kit supplied  
with the machine (see illustration in  
"Cleaning and care, water inlet").  
The filter for AD purified water (H O

The water in the machine is not suit-  
able for drinking.  
The inlet hoses should be connected  
to the respective cold and hot water  
stopcocks.  
If no hot water supply is available,  
the hose for hot water (red marking)  
must also be connected to the cold  
water supply. In this case both hoses  
must be connected to the cold water  
supply.  
In special cases, see Programme E  
in the chart, connection of both  
hoses to hot water is recommended.  
In order to prolong its life, the hose  
marked 90°C should only be used  
on a hot water connection supplying  
water no hotter than 70°C.

bar, or 0.3 - 1.5 bar the machine must  
be converted, if not supplied converted  
ex-works. An “ADP” booster pump  
can only be fitted. This is only possible  
when the machine has no DHK steam  
condensor. As this work requires  
specialised knowledge, it should only  
be carried out by a Miele approved  
engineer.

Drainage  
Ventilation of the wash cabinet  
at rear  
The drainage system is fitted with a  
non-return valve which prevents dirty  
water from flowing back into the ma-  
chine via the drain hose.  
For machines without DHK Steam con-  
densor, the rear ventilation of the wash  
cabinet should be connected to an on-  
site venting system.  
The machine should preferably be  
connected to a separate drainage  
system on site. If no separate drain-  
age system is available, seek profes-  
sional advice.  
Please refer to the Installation Instruc-  
tions provided.  
The machine is supplied with flexible  
drain hoses with an internal diameter  
of 22 mm and approx. 1.5 m long.  
The drain hose must not be short-  
ened.  
Hose clamps for connection are sup-  
plied.  
Longer drain hoses (up to 4 m) are  
available if required. Contact the  
Miele Service Department.  
The drainage system must not ex-  
ceed 4 metres and the drain pump  
has a maximum delivery head of 1  
metre.
