SAMSUNG F1045A Service Manual Operation Instruction & Installation

2. Safety Devices

※

We adapt 5 safety devices for users to use this wash machine safely.

1) Balancing device (ASSY-Main PCB)

→

When the lauandry is out of balance, to prevent the noises and vibrations, the unbalance

detecting sensor helps the laundry laid even and continue the dehydating process.

2) Anti-over water supply device

→

Because water supply valve is broken, once water is supplied to the 2/3 level of the door, the

water supplied is drained automatically, Over -flow error (E3) is diplayed on the panel

3) Temperature-regulating device(thermistor)

→

To prevent over-heating over the temperature setted up, THERMISTOR senses the temperature of

the machine continuously and helps the wash machine to work at the temperature given by users.

4) Overheating- controlling system

→

Under the circumstances of THERMISTOR inferiority or abnormal condition, if wash-heater is

overheated, automatically, assy -thermal fuse cuts off the power supply to protect the machine to

keep it safe.

5) Delicate clothing safeguard function(ASSY-Main PCB)

→

To protect the clothings which is weak to high temperature, the wash machine senses the

temperature inside the washing tub. if the temperature rises over 50℃wool washing course and

Delicate washing course display abnormal water temperature on the panel , after draining the

water.

5. Main function

1) Auto power S/W off function

●

After power on, the auto power S/W off function automatically switches power off for you if you do not press

selection button for 10 minutes

●

After selecting the function, the auto power S/W off function automatically switches power off for you if you do

not press start/pause button for 10 minutes

●

until 5 minutes past, After finishing the last function, the auto power S/W off function automatically switches

power off for you if you do not re-select the course button or manual button

2) Door open function

●

If door is open during the operating, all operating is halted, and door error message will be displayed (2-digit

panel displays "Ed" 4-digit panel displays "door") and error melody will coming out

●

Door open error can be cleared by closing the door. the operating keeps going on

3) Rinse hold function

●

If rinse hold function selected, the operating is finished , the machine do not drain the water after last rinse

4) No spin function

●

If no spin function selected, the operating is finished after last rinse

5) Drain function

●

Drain function is over, after pumping out the water for 2 minutes , without motor rotating

6) Pre-washing function

●

Pre-washing function can be selected ,when you choice the following mode; cotton, coloreds, sythetics, delicates,

baby cotton

●

Water level/reverse time is the same with the selected course

●

Pre-washing takes about 15 minutes

7) Rinse+ function

●

8) Power-out compensation function

●

If power is out on selected process, the process before power out is stored to EEPROM, once power is back

the process before power out continues.

●

When power is back, washing process starts from the process at the point of the power out, rinse/drain process

starts from the initial process.

9) Water heater Error function

①

This function starts working, when the heater works abnormally.

(this function begins sensing the heater 2 minutes later, after the heater operating)

②

The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes (Y=A2-A1)

- For 10 minute the variance of temperature(Y) is less than 2℃"HE2"message is displayed on the panel.

③

The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 11 minutes (Y=A2-A1)

- For 1 minute the variance of temperature(Y) increases more than 40℃(0.3V) "HE1"message is displayed on the

panel.

④

At this time heater, Error "HE2 (heater do not work), HE1(overheated)" is displayed and all working process off

⑤

The heater operating continues during heating hours, if washing hour is left over, the residual washing process

keeps going without heating.

10) Fuzzy washing function ( weight-sensing)

☞

After finishing initial water supply, when the fall of the water level needs supplementary water supply,

Sensing function perceives the weight with the supplementary water supply numbers and starts to work.

Under the course of Cotton, or Coloureds, if the supplementary water supply numbers become 3 - 4 times the

function is going at default condition ( high water level ), if 1-2 below that is going at middle level, if 0 below

low water level, heating hours and rinse hours depend on the above data.

ECO PRE mode is selected, the process going on at default condition.

※

After sensing weight, above hours is decreased from above default hours

11) Bubble -detecting function

At the each condition of washing&dehydrating , rinse&dehydrating , hydrating, bubble -detecting function works,

this function works 5times normally, if the function detects bubbles at 6 times , the bubble-detecting function

stops and go on to the next process.

Detecting function thinks there are bubbles and add the bubbles-removing rinse, needing hours are above

hours and 8 min 40 sec.

→

The bubble-detecting function during single hydrating process

after 2 times instant dehydrating and before main dehydrating , if the water level is 25.45KHZ below or

during main dehydrating, water level data is 23.80KHZ below Bubble-detecting function thinks there are

bubbles and add the bubbles-removing rinse 1 times, needing hours are above hours and 5 min 55 sec.

12) Unbalance detecting & laundry balance positioning system

①

Just before the hydrating process and just after reversal rotation for balancing laundry position, this function is

carried out

②

The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm for

initial 6 sec

③

Next 10 sec, the rotation increases the speed from 50 rpm to 90 rpm slowly

④

During the next 18 sec, drum rotates at the speed of 90 rpm, the sensor decides the degree of laundry

unbalance with TACHO data which is attached to motor

⑤

If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carries out

feed back process 6 times

13) R.P.M control

The rotating motor enables the magnetics( i.e generator) to generate magnetic flux in proportion to r.p.m,

magnetic flux induced by coil sensor in the opposite side produces the wave like the figure below to dΦ/dt and

via rectangual wave generating citcuit, the waves reaches MICOM and micom controls r.p.m with the pulse,

count and cycle inputted by program.
