A Warning and Safety Instructions

1 General information

Service and repair work should only be carried out by suitably qualified persons in accordance with all appropriate local and national safety regulations.

Servicing, modification, testing and maintenance of electrical appliances should only be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards.

All regulations of the appropriate utility supply companies and standards relating to safety (not limited to electrical safety) are to be complied with.

Before any service work is commenced, the machine must be disconnected from the mains.

Even with the machine switched off, mains power may be applied to some components.

A general visual check should always be carried out.

2 Risk of injury due to sharp edges

There may be a risk of injury due to sharp edges.

Protective gloves should be worn and the edge protection, Mat. no. 05057680, should be used.

Descriptive Technical Documentation

DTD no. 511-6055 A-3

3 Risk of electric shock when working on frequency

converter electronic unit (EFU)

PW 6055, PW 6065

Danger!

A capacitor on the frequency converter electronic unit holds an electrical charge with a potential difference of up to approx. 400 V, even after disconnection from the mains.

After disconnection from the mains a discharge resistor connected in parallel with the capacitor should discharge it within approx. 2 min.

For safety reasons before working on any of the frequency converter (EFU) components it is essential to ensure that this discharge has in fact taken place.

A-4 DTD no. 511-6055

4 Risk of electric shock when working on power-

programme module (ELP) (control-power module)

PW 5065

Danger!

A capacitor on the power-programme module (ELP) holds an electrical charge with a potential difference of up to approx. 400 V, even after disconnection from the mains.

After disconnection from the mains a discharge resistor connected in parallel with the capacitor should discharge it within approx. 2 min.

For safety reasons before working on any of the power-programme module (ELP) components it is essential to ensure that this discharge has in fact taken place.

Descriptive Technical Documentation

DTD no. 511-6055 A-5

5 Electrical connection via plug connector

It is always recommended to make electrical connection via a plug and socket so that electrical safety checks, e.g. during repair or service work, can be carried out easily.

The socket must be accessible after machine installation. This also applies even if an on-site mains switch is also already provided.

Models with a total connected load greater than 9 kW an additional on-site mains switch must also be provided.

Electrical connection must be carried out in accordance with all appropriate legal requirements, accident prevention regulations and valid standards.

A-6 DTD no. 511-6055

6 Touch current measurement

Note

Touch current measurement should be carried out on all accessible conductive parts that are not connected to earth.

Warning!

Touch current measurement should only be carried out after the ear th connection of the unit under test has been checked and found to be satisfactory!

Dangerous voltages may exist on defective machines as well as on accessible conductive parts that are not connected to earth!

Note

Touch current measurement should be carried out on the following accessible conductive parts:

• Door ring

2 Function

2.1 Heating

Overheating protection:

To protect the machine against overheating in case of a technical fault, e.g. if the heating relay contacts fuse together, the heater element has an overheating protection device.

If the overheating device trips, the heater element is destroyed and must be replaced.

2.2 Foam sensing

2.2.1 Excess foam when heating during the main wash

Foam is produced when the suds are heated. When the foam enters the ventilation system, the pressure in the suds container increases.

If, during heating, the analog pressure sensor registers an increase in pressure of 60 mm wc (mm water column) above washing level, the following occurs:

– The heating is switched off for 2 min. After this time, it is only switched on

again when the pressure increase has dropped to 15 mm wc above washing level. The fact that the desired temperature may not have been reached is not indicated as a fault.

– If excess foam is registered 3 times, the Thermostop step is skipped.

– At the end of the programme, the display shows Check dispensing.

– The fault indication F16 Excess foam is saved, see Fault code F16, excess

foam, 080 3.10.

2.2.2 During rinse water intake excess foam is in the drum vent or odour trap

If excess foam exists during rinsing, then during water intake the pressure in the suds container rises more rapidly than it would due merely to the incoming water.

If, during rinse water intake, the analog pressure sensor registers an increase in pressure of 40 mm wc within 4 s, the following occurs:

– The water intake is switched off for at least 15 s.

– After this time, it is only switched on again when the pressure increase has

dropped to 15 mm wc.

– At the end of the programme, the display shows Check dispensing.

– The fault indication F16 Excess foam is saved, see Fault code F16, excess

foam, 080 3.10.

Descriptive Technical Documentation

030-4 DTD no. 511-6055

2.2.3 During spinning excess foam is in the drum (water around drum circumference registered)

During spinning foam is produced and, due to centrifugal force, collects as water around the drum circumference. The pressure increases and the water acts as a brake on the drum.

If, during spinning, the analog pressure sensor registers a higher than expected pressure for the spin speed in operation or the desired/actual speed variation is greater than expected, the following occurs:

– The spin speed is reduced or the spin cycle is interrupted.

– If a spin above 700 rpm has not been carried out for a period of at least 60 s,

an additional rinse is activated.

– At the end of the programme, the display shows Check dispensing.

– The fault indication F16 Excess foam is saved, see Fault code F16, excess

foam, 080 3.10.

4 Service

4.1 NTC temperature sensor, R30

Danger!

Risk of electric shock when working on low-voltage components.

There is no circuit isolation between the power-programme module (ELP) and mains voltage.

When working on a machine connected to the mains, the possible application of mains potential to low-voltage components (e.g. NTC) must be taken into consideration.

4.2 Drum neck/suds container spacing gap setting

Note

The drum neck/suds container spacing gap must be set precisely to prevent the drum neck rubbing against the door seal during operation.

Note

Initial requirements:

– Drum, suds container, suds container cap and weights all pre-assembled.

– Pulley wheel secured on drive shaft.

– Motor bracket not secured.
