8. Connect the voltmeter across the float high level switch- Refer to Figure 6-
10 and connect the voltmeter leads to the red wire connections at the fill
solenoid and test point 2. Check for 115/120 VAC across these test
points.
• If the meter reads 115/120 VAC across these test points, the high level
switch is faulty. Replace the float assembly.
• If the meter reads 0 VAC, test the fill solenoid Valve.
9, As the water level rises to about one inch in the float cylinder, the lower
float begins to move up the shaft. Check the voltage readings across the
float low level switch.
• If the meter reads 115/120 VAC across the float low level switch, the
switch is faulty. Replace the float assembly.
• If the meter reads 0 VAC across the float low level switch and the
contactor does not energize, the float low level switch is good. Test the
contactor.
• If the meter leads 0 VAC across the float low level switch and the
contactor energizes, continue this procedure with step 10.
For 24-CGA-10 models:
• If the meter reads 0 VAC across the float low level switch and the relay
R1 does not energize, the float low level switch is good. Test the relay.
• If the meter reads 0 VAC across the float low level switch and the relay
R1 energizes, continue this procedure with step 10.
10. As the water level continues to rise in the float cylinder, the lower float
reaches its stop. The upper float starts to move up with the water level.
When the water level is about one inch from the top of the float cylinder,
the upper float magnet opens the upper level switch and de-energizes the
fill solenoid valve. The valve closes and the water level stops rising. As
the unit begins to generate steam, the water level drops, the upper float
energizes the fill solenoid, and the water fills to the upper level. The water
level and upper float cycle up and down two to five times per minute.
• If the float assembly performs as described above, it is operating
properly. End this procedure here.
• If the upper float does not cycle with the water level, it is jammed or
damaged, clean or replace the float assembly.
• If the water level in the cylinder continues to rise after the upper float
reaches the upper stop, continue this procedure with step 11.
11. Measure the voltage across the fill solenoid valve terminals.
• If the meter reads 115/120 VAC, the high level float switch is faulty.
Replace the float assembly.
• If the meter reads 0 VAC, the fault is not in the float assembly. Test the
fill solenoid valve.
