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