SECTION 9: OPTIONAL MODIFICATIONS
SECTION: 10 TROUBLE SHOOTING GUIDE
SYMPTOMS PROBABLE CAUSES ACTION TO BE TAKEN
Control won't turn "ON"
(Control light off).
Note: Control Cables must
be correctly plugged in
before power is turned on.
Improper power supplied (no power).
or
Control improperly connected.
or
Steam tank temperature limit switch is open
or
"PCA" printed circuit assembly is faulty.
or
Control cable is faulty.
or
Control is faulty.
1. a. Make sure circuit breaker is "ON", 230V supplied.
b. Using a voltmeter, check the voltage across the two fuses on the "PCA"
printed circuit assembly. Voltage should be 230V.
c. Check fuses on the PCA. If fuse(s) are blown, replace with 100 mA Time
Delay (F1) or 1A Non-Time Delay (F2)
fuse. If the fuse blows again - call AMEREC'S Service Department.
d. Use a small screwdriver or similar tool to reach through the hole in the
PCA near T1 and press the button on the limit switch to reset.
2. Turn off power to the generator.
3. Check control(s) installed per instructions. Re-apply power and test operation.
4. Replace PCA printed circuit assembly - call AMEREC'S Service Department.
5. Replace control cable - call AMEREC'S Service Department.
6. Replace the control - call AMEREC'S Service Department.
Control "OFF". (Control light
off)
Water won't shut off and runs
out of the steam head.
Water solenoid valve is stuck open.
or
"PCA" printed circuit assembly is faulty.
1. Turn off power to the generator. If the water stops, go to step 3.
2. a. Remove the water solenoid valve, dissassemble, clean,
re-assemble, and check for proper operation.
b. Replace valve - call AMEREC'S Service Department.
3. Replace the "PCA" printed circuit assembly - call AMEREC'S Service
Department.
Control "ON". (Control light
on)
Water won't shut off and runs
out of the steam head.
"PCA" printed circuit assembly is faulty.
or
Connection between the PCA and the water
level probe is faulty.
1. Check that the blue & white wires are properly attached to the water level probe.
Blue wire to the shortest level probe,white to the highest probes.
2. Remove and clean the level probe.
3. Replace the "PCA" printed circuit assembly - call AMEREC'S Service
Department.
Control "ON" (Control light
on), Tank drained.
Unit won't fill.
No water supplied (turned off?)
or
Plugged water solenoid valve.
or
Water solenoid valve is faulty.
or
"PCA" printed circuit assembly is faulty.
or
Level probe is faulty.
1. Check for proper water supply (Supply valve "on"). Check for closed drain valve.
2. Remove the blue wire from the level probe. If the unit fills, clean or replace the
level probe.
3. Reconnect the blue wire to the shortest level probe. At the water valve solenoid,
slide back the blue connector enough to get the voltmeter probes on the
solenoid terminals. Measure the voltage across the solenoid terminals. If it is
not 230V, replace the printed circuit assembly. If 230V is found
proceed with steps 4 & 5.
4. Remove water solenoid valve; disassemble, clean, reassemble, and check for
proper operation.
5. Replace the water solenoid valve - call AMEREC'S Service Department.
