Water supply problems.
– Make sure that the water supply line is open, and there is adequate flow and pressure.
Loose wiring, or clogged strainer in dual fill valves.
– Check the wiring to the float board and the dual fill valves.
– Check the strainer in the dual fill valves is not clogged – refer to
Valves and Drain Pump" on page 54
Drain pump running, or manual drain valve open.
– Check that the manual drain valve is closed, and the drain pump is not running.
Floats may be stuck.
– Visually check that the different LEDs on the float board light up as the water level in
the float chamber changes. If necessary, clean the float chamber – refer to
.
Fill valve relay on the driver board not seated properly, or defective.
CAUTION!
Electro-static discharge damage to board.
– Check that LED3 (corresponding to REL4 for the high volume fill valve) and LED4
(corresponding to REL5 for the low volume fill valve) on the driver board light up when
the fill valves are supposed to be energized. If not, check the relay(s) is seated prop
-
erly on the driver board.
– Swap the relay(s) with another relay on the board to verify that it is working. If neces
