• If the machine is used in a commercial environment it may only be operated by instructed/trained personnel. If the machine is used in a publicly accessible area, the supervisor must ensure that it can be operated safely without risk of danger.

• The washing machine must not be used in a non-stationary installation site (e.g. on a ship).

• This washing machine can only be used by people with reduced physical, sensory or mental capabilities, or lack of experience or knowledge, if they are supervised whilst using it or have been shown how to use it in a safe way and understand and recognise  the consequences of incorrect operation.

• Children under the age of 8 must not be allowed near the washing machine unless they are constantly supervised.

• Children over the age of 8 may only use the washing machine without supervision if its operation has been clearly explained to them and they are able to use it safely. Children must be able to understand and  recognise the possible dangers caused by
  incorrect operation.

• Children may not carry out cleaning or maintenance on the washing machine unsupervised.

• Always supervise any children in the vicinity of the washing machine. Never allow children to play with the washing machine.

• Disinfection programmes must not be interrupted, as this can have a limiting effect on the disinfection result. It is the operator’s responsibilityto ensure that the standard of disinfection in thermal as well as chemo-thermal procedures is maintained by carrying out suitable validation tests.

Foreseeable misuse

• Never use solvent-based cleaning agents, e.g. those containing benzine, in this machine. Doing so may result in damage to component parts and create toxic steam and fumes. Risk of fire and explosion!
• When washing with high temperatures, remember that the porthole glass becomes hot. Do not let children touch it during the wash process.

Danger of burning!

• Close the drum door after each wash cycle. This is to avoid the risk of children trying to climb into the washing machine or hide things in it, and animals getting into the machine.

• Do not damage, remove or bypass the safety features or control elements of this washing machine.

• Machines with a damaged control panel, wires or cables must not be used until they have been repaired.

• Water used for washing in this machine consists of suds and is not drinking water! Drain the suds into a proper drainage system.

• Always make sure that the drum is stationary before reaching in to remove laundry. Reaching into a moving drum is extremely dangerous.

• Be careful not to put your hands in the gap between door and frame when closing the drum door.
  Please note: the drum door is locked automatically as soon as the washing machine starts.

• It is particularly important to follow the manufacturer’s instructions when using a combination of cleaning agents and special application products. Products must only be used for applications approved by the manufacturer to avoid any material damage or  the occurrence of strong chemical reactions.

Technical safety

• Before setting up the washing machine, check it for any externally visible damage. Do not install or use a damaged washing machine.

• The electrical safety of this washing machine can only be guaranteed when correctly earthed. It is most important that this basic safety requirement is tested and in case of any doubt the on-site wiring system should be inspected by a specialist. Miele cannot  be held liable for the consequences of an inadequate earthing system.

• Unauthorised repairs could result in unforeseen dangers for the user, for which the manufacturer cannot accept liability. Repairs should only be undertaken by a Miele authorised technician, otherwise any subsequent damage will not be covered by the warranty.

• Do not make any alterations to the washing machine, unless authorised to do so by Miele.

• Disconnect the washing machine from the power supply in the event of a fault and for cleaning and maintenance. The washing machine is only electrically disconnected from the power supply when:
  – the plug of the washing machine is unplugged, or
  – the mains fuse is disconnected, or
  – the screw-in fuse has been completely removed
  For more information, see “Installation – Electrical connection”.

• The washing machine may only be connected to the water supply using the set of hoses supplied with the machine. Old sets of hoses must not be re-used. Check the sets of hoses regularly for signs of wear. Change the sets of hoses in good time to avoid the  risk of leaks and subsequent water damage.

• The cause of any leaks must be dealt with before the washing machine is restarted. Disconnect the washing machine immediately if any water leaks out.

• Faulty components must only be replaced by genuine Miele spare parts. Miele can only guarantee the safety standards of the machine when Miele spare parts are used.

• All relevant national provisions and regulations (DGUV in Germany) relating to accident insurance are applicable to this machine. It is recommended to carry out testing in accordance with the regulatory framework described in DGUV 100-500/Chapter 2.6/Section 4. The test book required for the documentation is available from the Miele Customer Service Department.

• Please observe the instructions in “Installation and connection” and “Technical data”.

• The plug for the washing machine must always be kept accessible so that the machine can be easily disconnected from the power supply.

• For hard-wired machines, an all-pole means of deactivation must be provided on site.

• If the machine is to be hard-wired, there must be a means of disconnecting all poles from the power supply. The mains isolator must be close to the washing machine and be clearly identifiable, unhindered and easily accessible at all times.

Correct use

• The maximum load size for PWM 909 is 9.0 kg of dry laundry. See the “Programme chart” for the maximum recommended load sizes for individual programmes.

• Before using the washing machine for the first time, check that the transit bars have been removed (see “Installation – Removing the transit bars”). During spinning, transit bars which are still in place may result in damage to both the washing machine and  adjacent furniture or machines.

• Never try to open the drum door of the washing machine using force. The door can only be opened when a corresponding message appears in the display.

• Do not push the suspended drum unit while the machine is running.

• When closing the door there is a danger of crushing and shearing between the door frame and the drum opening and also at the hinges.
  Caution: the drum door locks automatically when the machine is started.

• Close the stopcock if the washing machine is to be left for any length of time (e.g. while on holiday), especially if there is no floor drain (gully) in the immediate vicinity.

• Take care to ensure that foreign objects (e.g. nails, pins, coins, paper clips) do not find their way into the machine with the laundry.
  Foreign objects may damage components of the machine (e.g. suds container, drum). Damaged components can damage the laundry.

• If the correct amount of detergent is dispensed, the washing machine should not need to be descaled. If, however, you do wish to descale your washing machine, only use proprietary non-corrosive descaling agents. Special descaling agent is available from  your Miele dealer or from the Miele Customer Service Department.
  Strictly observe the instructions for the descaler.

• Textiles which have been pre-treated in solvent-based cleaning agents must be rinsed in clean water before being washed in the machine. Note that solvent residues may only be discharged into waste water in compliance with local legislation.

• Never use solvent-based cleaning agents, e.g. those containing benzine, in this machine. Doing so may result in damage to component parts and create toxic steam and fumes. Risk of fire and explosion!

• Do not store or use petrol, paraffin or any easily flammable substances near the washing machine. Do not use the machine lid as storage space.
  Risk of fire and explosion!

• Do not store chemicals (liquid detergents, additives) on the machine lid. They may cause discolouration or lacquer damage. Accidently spilled chemicals should be removed from the surface immediately with a wet cloth.

• Only use dyes, dye removers and descalers suitable for use in a washing machine. The manufacturer’s instructions on the packaging must be observed.

• Dye removers contain sulphur compounds which can cause damage such as corrosion. Do not use these products in this washing machine.

• Avoid contact of stainless steel surfaces with liquid cleaning and disinfecting agents which contain chlorine or sodium hypochlorite.
  These agents can have a corrosive effect on stainless steel. Aggressive chlorine bleach vapours can also be corrosive. Do not store open containers of these agents near the machine.

• Do not use a pressure washer or hose to clean the washing machine.

Chlorine and component damage

• Frequent use of chlorine products increases the risk of damage to components.

• The use of substances containing chlorine, such as sodium hypochlorite and chlorine bleach in powder form, can result in damage to the protective layer of stainless steel and corrosion on components.
  Therefore, refrain from using substances containing chlorine. Use oxygen-based bleaching agents instead.
  If, however, chlorine bleaching agents are used, an anti-chlorine treat- ment must always be carried out. Otherwise, both the washing machine components and the laundry may suffer persistent and irreparable damage.

• Anti-chlorine treatment must be carried out immediately after chlorine bleaching agents have been used. Hydrogen peroxide as well as oxygen-based detergents and bleaching agents are suitable for anti-chlorine treatment. The suds must not be drained in  between.
  Treatments with thiosulphates can result in gypsum-like deposits particularly when used in combination with hard water. This gypsum can build up in the washing machine or cause incrustations on the laundry. Treatment with hydrogen peroxide is recommended over treatment with thiosulphates because hydrogen peroxide neutralises chlorine.
  The exact dispensing quantities and the treatment temperatures required must be set and tested on site in accordance with the dispensing recommendations of the detergent and cleaning agent manufacturers. The laundry must also be tested to check whether it contains any active chlorine residues.

Accessories

• Accessory parts may only be fitted when expressly approved by Miele. If other parts are used, warranty, performance and/or product liability claims will be invalidated.

Disposing of your old machine

• Ensure that the door locks are unusable when disposing of or scrapping old washing machines. This will prevent the risk of children accidentally locking themselves in while playing and endangering their lives.

Miele cannot be held liable for damage caused by non-compliance with these safety notes and warnings.
