Adjusting the water softener

To avoid the build-up of calcium depos its on items being cleaned and disin

fected in the washer/disinfector, the water may need to be softened (where the supply hardness exceeds 107 ppm CaCO3).

To ensure a steady supply of soft water, the water softener must always be:

correctly set

–

regenerated with salt as soon as the

–

REACTIVATION indicator light comes on.

The water softener should be set to cor respond with the water hardness upon installation of the washer/ disinfector.

Your local water authority can advise you on the water hardness in your ara.

Setting the water softener

The hardness range is divided into 18

units and a zero position. The washer/ disinfector is set at the factory for a water hardness setting of 8, corre sponding to 339 ppm CaCO3. If your water supply is harder or softer than this, change the setting as follows:

Reactivating the water softener

When the REACTIVATION indicator light on the left hand side of the control panel comes on during a cycle, the built-in water softener is depleted and cannot supply any more soft water.

It should be reactivated with salt as soon as the wash cycle has finished. If this cannot be done, and further loads have been washed, then the reactiva tion process should be carried out twice

in succession.

Each reactivation cycle requires:

4.4 lbs (2 kg) of water softener salt. A

granule size of 1 to 4 mm is recommended by Miele. Do not use any other type of salt, it may damage the water softener.

^ The plastic salt container which is

supplied with the washer/disinfector.

IMPORTANT: If the only reactivation salt available is fine grain, please consult the Miele Technical Service Department. Water softener salt with granules larger than 4 mm cannot be used.

Filling the salt container

1. Unscrew the filter insert from the salt

container and remove.

WARNING: PERSONAL INJURY/ EQUIPMENT DAMAGE HAZARD Do not fill container with cleaning detergent! Fill with reactivation salt only! Detergents can be corrosive, causing potential personal injury and damage to the water softener.

2. Fill the salt container with approx.

4.4 lbs (2 kg) of granular salt and screw the filter insert back in place.

Reactivating the water softener

Position the salt container as follows:

1. Remove the lower basket from the

machine.

2. Unscrew the plastic cap in the base of the wash cabinet.

4. Close the door.

The filters must be cleaned when dirty, otherwise insufficient water will flow into the wash cabinet. These filters must be periodically inspected based on the quality of incoming water.

^ Clean the large area filter (1) and the

fine filter (2) or replace if necessary.

^ After reconnection, turn on the valves

and test for leaks.

Maintaining the dispensing system

The dispensing system should be main-tained at regular intervals in order to guarantee optimum safety and effi ciency.

The tubes in the dispensing system should be replaced every 2 years.

Cleaning and care

Maintaining the drying unit

To ensure thorough cleaning without recontamination, the air filters have to be exchanged after their life cycle (coarse filter = 100 operating hours, clean room filter = 500 operating hours).

1. Changing the coarse filter

The coarse filter is located on the dry ing unit behind the unit’s front panel, which can be pulled out.

Correcting minor problems

Unsatisfactory cleaning results

Unsatisfactory cleaning results may ap pear as drying spots, or as spots that look like corrosion.

Presumably corrosive spots often are bio-debris. They have the shape of dry ing spots, blurry edges, and the color of rust. Bio-debris may also appear on surfaces that were not decontaminated before processing.

Please observe:

Have the instruments been stored in

the washer/disinfector for more than 6 hours? If so, please run the washer/disinfector, even partially loaded, within 6 hours of loading.

^ Was enough detergent used? Please

check the dosage of the detergent and adjust, if necessary. Too little as well as too much detergent may deteriorate the cleaning results.

^ Can both spray arms rotate easily,

when the washer/disinfector is loaded? If not, please rearrange the goods to be cleaned in a way so that the spray arms can rotate freely.

The water in the wash cabinet is not heated; the cycle lasts too long

This washer/disinfector has a resettable temperature sensor which will shut off the heating elements in the case of over-heating. This could be caused if
