temperature-testing resist value; when the control panel makes sure that the water
temperature arrives the set temperature, it cuts off the heater and stop heating.
The control of unbalanced load during spinning
When the washing machine is running the spinning program, if the clothes in the drum
are put unbalanced or gravely out of center, the washing machine will vibrate greatly, so
the control panel needs to adjust it. The detailed process is as below: when the washing
machine is running the spinning, the drum rotating speed will promote from low to high;
when it gets to 95r/min ,according to the principal that different eccentric clothes have
different rotating speed between ascending and descending, the control panel first checks
the testing motor’s rotating speed difference at 95rpm, after a special computing,
estimates whether the clothes in the drum balanced, such as balanced distribution. If
balanced, the washing machine will run at normal spinning speed until the set highest
rotating speed. If unbalanced, after the control panel cutting off the controlling motor 5
seconds, the drum runs 30 seconds at washing speed. It shakes the clothes, tests and
computes the motor's rotating speed , and estimates whether the distribution balanced.
This procedure runs 12 times until the clothes balanced to spin. If the eccentricity is still
large after 12 modulations, it will display UE urgent.
Now turn off the machine, open the machine door to replace the clothes or put more
clothes to descend the eccentricity, and then choose the spinning program again.
NOTE
: usually, a towel, jeans and some fabrics have large eccentricity
and suggest that
consumers should put 2~3 or more to wash.
