Removing the transport locks

Caution! Damage to the appliance

  • The appliance is secured for transportation using transport locks. If the transport locks are not removed, the appliance may become damaged when it is operated. Before using the appliance for the first time, make sure that you completely remove all four transport locks. Keep the locks in a safe place.
  • To prevent transport damage from occurring if the appliance is moved at a later date, you must refit the transport locks before transporting the appliance.

Note: Keep the screws and sleeves in a safe place.

1. Take the hoses out of the holders

2. Unscrew and remove all four transportation securing bolts with a wrench (WAF 13). Remove the sleeves. Remove the mains cable from the holders.

3. Insert the covers. Lock the covers firmly in place by applying pressure to the snap-in hooks.

Hose and cable lengths

  • Left-hand connection

  • Right-hand connection

Tip: The following are available from specialist dealers/the after-sales service:

  • Extension for Aqua-Stop and cold water supply hose (approx. 2.50 m); order no. WM Z2380, WZ 10130, CZ 11350, Z 7070X0
  • A longer supply hose (approx. 2.20 m) for standard models; individual component number for customer services: 00353925

Water inlet

Warning Risk of death! There is a risk of electric shock if you touch live components. Do not immerse the Aqua-Stop safety valve* in water (it contains an electric valve).

Notes

  • Only operate the appliance using cold mains water.
  • Do not connect the appliance to the mixer tap of an unpressurised hotwater boiler.
  • Do not use a used supply hose. Only use the supply hose supplied or one that was purchased from an authorized specialist retailer.
  • Do not kink or squash the water supply hose.
  • Do not alter (shorten, cut through) the water supply hose (otherwise its strength is no longer guaranteed).
  • Only tighten the screw connections by hand. If the screw connections are tightened too much with a tool (pliers), the thread may be damaged.
  • When connecting to a 21 mm = ½" tap, first fit an adapter* with a sealing washer from 21 mm = ½" to 26.4 mm = ¾".

Optimum water pressure in the supply network

At least 100 kPa (1 bar)

Maximum 1000 kPa (10 bar)

When the tap is open, the water flow is at least 8 l/min.

If the water pressure is higher than this, a pressure-reducing valve must be installed.

Connection

Connect the water supply hose to the tap (26.4 mm = ¾") and to the appliance (not necessary for Aqua-Stop models as this is permanently installed):

  • Model: Standard

  • Model: Aqua-Secure

  • Model: Aqua-Stop

Note: Turn on the tap carefully, checking the leak tightness of the connection points. The screw connection is under mains water pressure.

Water outlet

Caution! Water damage

When water is being pumped away, the outlet hose is under water pressure and may slip out of the wash basin or connection point. Secure the drain hose so that it cannot slip out.

Caution! Damage to the appliance/fabrics

If the end of the drain hose is immersed in the drained water, water may be sucked back into the appliance and may damage the appliance/fabrics. Make sure that:

  • The plug does not block drainage from the washbasin.
  • The end of the drain hose is not immersed in the drained water.
  • The water drains away quickly enough.

Note: Do not kink the water drain hose or put strain on it lengthways.

Connection

  • Drainage into a washbasin

  • Drainage into a siphon

The connection point must be secured using a hose clamp with a diameter of 24 - 40 mm (available from specialist dealers).

  • Drainage into a plastic pipe with rubber bushing or into a drainage pit

Levelling

Align the appliance using a spirit level. Incorrect alignment may result in loud noises, vibrations and machine "movement".

1. Loosen the lock nuts using a WAF17 spanner, by turning it in a clockwise direction.

2. Check the alignment of the washing machine with a spirit level, and adjust it if necessary. Change the height by turning the appliance feet. All four appliance feet must stand firmly on the ground.

3. The lock nuts on all four appliance feet must be screwed tightly against the housing using a suitable WAF17 spanner. In doing so, hold the foot tight and do not adjust its height.

Electrical connection

Warning Danger of death!

  • Never touch or hold the mains plug with wet hands.
  • Only pull out the mains cable by the plug and never by the cable, as this could damage it.
  • Never unplug the mains plug during operation.

Observe the following information and ensure that:

Notes

  • The mains voltage and voltage indicated on the appliance (rating plate) are the same. The connected load and fuse required are specified on the rating plate
  • The appliance is only connected to an alternating current via a properly installed earthed socket.
  • The mains plug fits the socket.
  • The earthing system is properly installed.
  • The mains cable is only replaced by a qualified electrician (if this is necessary). Replacement mains cables are available from the aftersales service.
  • No multiple plugs/couplings or extension cables are used.
  • If an earth-leakage circuit breaker is used, only a type which displays this symbol is used: .Only this symbol guarantees compliance with the currently applicable regulations.
  • The mains plug can be accessed at all times. If this is not possible, in order to comply with the relevant safety regulations, a switch (2-pole switch-off) must be built into the permanent installation in accordance with electrical installation regulations
  • The mains cable is not kinked, squashed, altered or cut through
  • The mains cable does not come into contact with heat sources.

Before washing for the first time

The washing machine was thoroughly tested before leaving the factory.To remove any water that may be left over from the test, run the first wash cycle without any laundry.

Preparatory work:

1. Check the machine.

2. Remove the protective film from the control panel.

3. Plug in the mains plug.

4. Turn on the tap.

Running the programme without laundry:

1. Switch on the appliance.

2. Close the door (do not load any laundry).

3. Set the Drum Clean 90 °C programme

4. Open the detergent drawer.

5. Pour approximately 1 litre of water into compartment II

6. Pour standard washing powder into compartment II

Note: To prevent foaming, only use half the amount of detergent recommended by the detergent manufacturer.Do not use detergents intended for woollens or delicates.

7. Close the detergent drawer

8. Press the button.

9. Switch off the appliance at the end of the programme

Your washing machine is now ready to use.

Transportation

Preparatory work:

1. Turn off the water tap.

2. Reduce the water pressure in the supply hose.→ Page 45; Cleaning and maintenance – filter in the water supply blocked

3. Disconnect the washing machine from the mains.

4. Drain the remaining water: → Page 44; cleaning and maintenance – the drain pump is blocked, emergency draining

5. Remove the hoses.

Fitting the transportation securing means:

1. Remove the covers and keep them in a safe place. If required, use a screwdriver

2. Insert all four sleeves. Clip the mains cable securely in the holders. Insert the transportation securing bolts and tighten them with a wrench (WAF 13).

Before switching on the appliance again:

Notes

  • The support struts must be removed.
  • Pour approx. 1 litre of water into dispenser II, select the Drain programme and start. This will prevent detergent from flowing straight into the drain during the next wash.

  • Look out for metal items (paperclips, etc.) and remove them.
  • Wash delicates in a net or bag (tights, underwired bras, etc).
  • Close zips, button up covers.
  • Brush sand out of pockets and collars.
  • Remove curtain fittings or place in a net/bag

Sorting laundry
