TROUBLE SHOOTING
CHECKING OPERATION OF REED SWITCHES
The curtain flap switches and the high and low floats have indicator (red LED) lights on the
main circuit board.
To check the operation of these switches, set the machine in the WARM UP CYCLE with no
water in the water trough.
CURTAIN FLAP SWITCHES
By moving the water curtains ,the lights marked FLAP 1 and FLAP 2 should be on when the
curtain is closed and off when the curtain is about 10 to 15mm open.
LOW FLOAT
With the low float all the way down, the indicator light should be off, but by moving the float
up the indicator light should come on.
NOTE: If the reverse is happening, the float itself is around the wrong way. Remove the clip
at the bottom, take the float off and re-install the float the other way round.
HIGH FLOAT
With the float in down position, the light should be off, but by moving the float up, the light
should come on.
NOTE: If the reverse is happening, rotate the whole float switch assembly 180degrees
ELECTRONIC CIRCUIT BOARDS FUSE - MAIN CIRCUIT BOARD
The main circuit board is protected by a fuse. If this fuse should blow it will isolate the whole
machine. The correct replacement fuse is a slow blow HRC Ceramic. Refer parts list for
correct size.
DO NOT USE GLASS TYPE FUSES
When changing circuit boards ensure that:
(a) The incoming active goes to the relay tab marked COM.
(b) The ribbon cable connecting the two boards is correctly orientated, i.e. red cable
on top of main circuit board and on bottom of the control board.
