Text Box: Text Box: 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.
