A Warning and Safety Instructions

1 General

All repairs should be performed by a trained technician in strict accordance with national, state and local codes. Any repairs or maintenance performed by unqualified personnel could be dangerous.

When servicing, modifying, testing or maintaining appliances, all applicable laws, regulations and accident prevention guidelines must be observed.

Before star ting any service work, disconnect the machine from its power source.

Even with the machine switched off, voltage may exist on some components.

Do not work on the washer while it is carrying voltage. If this becomes unavoidable, as in the process of locating faults, put extra safety measures into place.

After work has been completed, as a matter of standard practice, a visual as well as an operational check should be performed.

2 Voltage present on power electronic (ELP)

Danger!

A capacitor on the power electronic (ELP) maintains voltage of up to approx. 400 V, even after the appliance is disconnected from power.

After the appliance is disconnected from power, an electrical resistor discharges the capacitor within approx. 2 minutes.

Work on the power electronic (ELP) may only be started after it has been established that the capacitor has been safely discharged.

4 Touch current measurement

Note

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

Warning!

Touch current measurement should only be carried out after the ground 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 ground!

Note

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

• Door ring.

2 Function

2.1 Pull door lock (A2)

2.1.1 Electromagnetic door lock

When locking the door, the locking latch dips into the lock and is pulled into the lock by the locking mechanism.

The power electronic (ELP) registers the locked state via a switch in the door lock (A2).

During operation, with the door closed, the door lock is electromagnetically bolted, refer to 020 2.1.2 Safety requirements.

As long as the door is not electromagnetically bolted, the door can be opened by simply pulling it.

Activating the emergency release cancels the electromagnetic lock, and the door can be opened.

Danger!

Opening the door by means of the emergency release may present danger of injury by a rotating drum, danger of scalding suds and flooding.

Note

Closing the door when the door lock is already locked causes damage to the door lock.

If the door lock is locked, with the door open, it has to be released manually, refer to Door lock (A2) – Open manually, 020 4.1.

2.1.2 Safety requirements

After pressing the “Start” pad, the electromechanical door lock is only activated when the following safety requirements are met:

– Drum speed < 7 min

-1

, registered by RPM sensor (Tachogenerator),

– Water level < 80 mmWS, registered by analog pressure sensor (ADS),

– Suds temperature < 131°F (55°C), registered by suds temperature sensor

(NTC resistor R30).

3 Fault Repair

3.1 Door lock (A2) does not lock

Symptom

The door latch hits the locking mechanism when pushing into the door lock (A2).

Cause

The locking mechanism is locked, with the door open.

Remedy

A Open the door lock (A2) manually, refer to Door lock (A2) – Open manually,

020 4.1.

A Check the function of the door lock (A2).

Fig. 1

A With the front panel in place, the door lock (A2) and the door seal fitted, press

the door locking mechanism open.

4 Service

4.1 Door lock (A2) – Open manually

Note

Manual opening is only required when the door locking mechanism is locked, with the door open.

This happens if the locking mechanism is interfered with, e.g. if an object is pushed into it.

In this situation, the locking latch cannot push into the lock and the door can't be closed.

A Lift the door lock (A2) and remove.

A Pull the plug off.
