Function DWF-100M's,100C's,1098's DWF-900's, 160's, 170's, 174W's DWF-750's, 800's
"E9" signal The PCB have a function of checking frequency from Pressure switch in order to decide the proper water level
after load sensing process.
If no frequency is checked by Micom, PCB display the "E9" error mode.
Checking point here is that check the connector and wire-open and Micom condition.
The solving method is first OFF the power and unplug and then change the defective part.
Note : Processing of operation of Pressure switch.
water level
→
water pressure
→
push the diapharm in the switch
→
moving magnetic core in the switch
→
emit the freqnecy from low level(22KHz, response to high water level) to high level(25KHz, low water level) linearly.
Automatic The washer provide some energy saving function by electron power switch in PCB.
power OFF
The PCB off the power of washer immediately after finishing all process properly.
And, in case of only pressing power button and pressing Start/Hold button during processing without any next action,
the power is offed after 10 minute automatically.
Auto Drain The washer have some safety-proof function, the one is to prevent water from flowing on the floor in case of
abnornal condition during washing.
If huge amount of water is to be poured beyond high water level, the Drain pump is operated automatically
so as not to cause serious problem when the water level reach over 30~50mm.
Checking point
The Water Inlet valve can not OFF itself even though power OFFed.
The PCB can not control this part(Inlet Valve) because of breaking off the related parts(such as Triac, etc).
The Pressure switch can not work properly by bended-air tube and clogged-air tube and broken itself.
