Frequency of maintenance should be based on the machine's degree of use. Daily • Check door and safety lock: - Open the door and try to start machine. It should not start. - Close the door, start machine and try to open the door. It should not be possible to open the door. - Make sure the door does not leak. - Clean the door seal of any residual detergent.

Service Manual 11 12. Fault Tracing Function checks It is possible to test the machine's various functions by inputting a numerical code using the key set. The function chosen can then be turned on and off using the start button. Program indicator no. 10 shows if the function is turned on or off.
Service Manual 12. Function Sequences General This chapter describes a machine with the wash program P02CH. The machine has an electromechanical programmer, hot and cold water connection, without heating and wash programs for laundrettes, coin-ops etc. To facilitate fault-tracing in the machine electronics, the circuit diagram is divided into functional sequences. The following sequences are described in this chapter: • Power supply and start, machines without coin meter .......

When the machine starts, the solenoid locks the lock knob by drawing the lock bolt into closed position. A microswitch in the delay unit is controlled by the lock bolt and indicates that the lock bolt is in closed position. Only when this signal is received does the drum start to rotate and water begin to fill the drum.

Inlet Valve, Water 8911 1 Type Edition Page 34 Data Capacity at 300 kPa 300 litres/min Operating limits 40-1000 kPa Coil Description Armature The valve is electromagnetically operated and has a rubber diaphragm as its opening and closing element. The valve utilises the water pressure when opening and closing. When the electromagnetic is de-energised, the valve is closed. The water pressure acts through the pilot pressure opening on the top of the rubber diaphragm.

34 4 9109 2 Type Edition Page Service Manual 34. Water inlet valve Repair instructions 3 Lime deposits can block the valve diaphragm hole and prevent the valve from functioning properly. It is therefore a good idea to take apart and clean the valve regularly depending on operation conditions and the degree of polutants and lime content present in the water. Valve does not open • Check that there is voltage supply to the coil.
Service Manual Description Fig. 1 5 38. Drain valve The drain valve utilises the water pressure in the cold water inlet to close the valve. A hose (1) connects the water inlet and the control valve (2). When the control valve is activated, it opens and allows water to pass through the supply main (3) which is connected to the drain valve. The water pushes up a rubber diaphragm (4) and a piston (5) by means of a pressure plate (6) which closes the rubber diaphragm (7) on the valve.

Coin meter Alternative 2: Timed coin meter (Available only on the Swedish market) When the coin slot with coin or token is pushed in, the slot actuates a catch which advances a wheel. This actuates a microswitch which provides power (phase) to the automatic unit of the machine. It is now possible to start the machine. The paid time has run out. The wheel is turned so that the microswitch cuts the phase to the automatic unit and timer motor.
