PART IV
TROUBLESHOOTING - CHECK LIGHT FLASHING
E-33
ENGLISH
Check power supply
If you did not find any problem in the cell, go to investigate the power supply.
1. Put the unit on the repair table. Make sure the cell is placed correctly to connect the unit power contact plate.
2. Open the bottom plate by removing 4 screws with cross screwdriver.
3. Turn on the unit, check the red and green light on the circuit board.
Check the electronic cell
1. If the cell is put in opposite way or missing to put cell in the unit? It will cause the CHECK indicator light on the control panel
flashing.
2. Lift the cell in front of a bright light and look through, visually inspect if there are broken or bent ionizer wires or if the collector
plates are bent or deformed.
3. If the cell is wet after washing or with other reasons? Please dry the cell thoroughly. When the cell is wet, the ionizer wires and
positive plates cannot be insulated from the ground, causing a short circuit so the voltage on the check wire will be decreased
less than 1V DC, leading to the CHECK indicator light flashing. If the square ceramic insulator of the cell was burnt and cracked
down because of a long time use of the wet cell, also causing the CHECK light to flash.
Helpful hints
A simple way to check the cell:
1. Open the front panel, lift out the cell and put it again.
2. Try to change another cell, check if the CHECK light still flashes.
If yes, the cell may be a problem.

Step 1
Check power supply
Step 2
3. The green light does not
illuminate or the red light does not
flash you need to check the power
supply transformer and the main
circuit board. If they are OK, you
need to replace the power supply.
4. If the green light blinks every 15
seconds you need to check red
check wire. When the red check
wire is loosened the green light
blinks.
1. If the green light illuminate but
the red check light flashes you
need to check if you missed to put
the cell in the unit or the cell is not
put correctly.
2. If only the red check light is
flashing you will need to check if
the cell is short circuited. If the cell
is OK, you need to replace the
power supply.
