SYMPTOMS PROBABLE CAUSES ACTION TO BE TAKEN

TABLE 2 Cont.

Master unit “ON”

Slave tank drained.

Slave unit won’t fill up.

Improper or no power supplied

No water Supplied

Plugged water solenoid valve

Water level probe is faulty

Burnt out heating elements

AG or 3G PCA is faulty

Slave control cable is faulty

AK or 3K in the Master unit is faulty.

1.a. Make sure the circuit breaker to the Slave unit is “ON”.

b. Using a voltmeter, check the voltage across the two fuses on the

Slave PAL. Voltage should be 208/240V.

c. Check fuses on the Slave PAL. If fuse(s) are blown, replace with

equivalent fuse. If the fuse blows again- Call Steam Technical Support.

2. Check for proper water supply (supply valve “ON”). Check for drain

valve close.

3. Remove the blue wire from the level probe. If the unit fills,, clean or

replace the level probe.

4. Reconnect the blue wire to the shortest level probe. At the water

valve solenoid, slide back the red connector enough to get the voltmeter

probes on the solenoid terminals. Measure the voltage across the

solenoid terminals. If it is not 208/240V, replace the PCA. If 208/240V is

found, proceed with steps 5 & 6.

5. Remove water solenoid valve: disassemble, clean, reassemble and

check for proper operation.

6. Replace the water solenoid valve.

7. Call AMEREC Service Department.

Water continually sputters out of

any steam head.

Foaming contaminants in the

water supply.

1. Flush tank 3 times. See Section 8: FLUSHING PROCEDURE.

2. Call Steam Technical Support.
