3.7 HEATING CONTROL

♦ When the temperature set by the user is higher than the water temperature,
the PCB will control the heater to function and run the heating process until the
water temperature reaches the set temperature.
♦ When the temperature set by the user is higher than the water temperature,
no heating operation is required.
♦ The heater is enabled and proceeds to function until 3 seconds pass by after
the set temperature is reached.
♦ When the water level is below the "Heating water level", the heater should be
forced to shut down, and then replenish water.

3.8 SPINNING CONTROL

♦ During draining, the Spinning process will begin after the water of tub is
discharged down to the "Spinning water level".
♦ The PCB controls the motor to drive the drum to rotate in clockwise direction.
Carry out distribution measurement at low speed (about 110rpm) first, and then
measure the equilibrium value. After the equilibrium value is up to standard, the
distribution measurement succeeds, and enter the stage of high-speed
Spinning.If the distribution measurement fails as the equilibrium value is too big
and does not meet the requirements, then it is necessary to continuously carry
out distribution measurement operation.
♦ Spin speed limit: The spin speed shall neither exceed the maximum speed set
by the program nor exceed the speed manually set via the "Spin" button.
