VL SERIES STEAMER - TROUBLESHOOTING
SYMPTOM POSSIBLE
CAUSES
Pa
e 85 of 88
Boiler base will not heat or build
pressure.
1. Check incomin
volta
e.
2. Boiler not filled - check fill solenoid for power, clo
in
or
malfunction.
3. Water Level Control malfunction. HL-3 relay not ener
izin
or contacts not closin
to power boiler fill solenoid.
4. Water too “pure” for probes to properly conduct electricity.
5. Contactor malfunction (electric only).
6. Heatin
element inoperative (electric only).
7. Cyclin
pressure switch open or set too hi
h. Steamer is
cyclin
on hi
h limit.
8. Hi
h limit thermostat open.
9. Problem with auto blowdown timer (older models).
10. Power switch malfunction.
11. Pressure reducin
valve malfunction or needs cleaned
(direct or re
enerated models only).
12. Low or no steam supply to steamer (direct or re
enerated
models only).
Steam output low or slow cookin
. 1. Steam
ate valve not fully openin
or blocked.
2. Cyclin
pressure switch malfunction or needs adjustment.
3. Steam header line (supply) blocka
e.
4. Heavy amount of condensate in the pressure controls steam
supply line.
5. Pressure relief valve leakin
.
6. Steam supply lines leakin
.
Boiler leaks water. 1. Loose water, steam or drain line connections (top or base).
2. Boiler hand hole
asket not sealin
.
3. Leak at
au
e
lass.
Boiler fill solenoid cyclin
to frequently. 1. LL probe lime scaled over (dry) or dama
ed and not sensin
water.
2. Water level control malfunction.
Boiler water level too hi
h. 1. Fill solenoid does not shut off.
2. Hi
h level probe lime scaled over (dry) or dama
ed and is
not sensin
water (open circuit).
3. Water level control malfunction. HL-3 relay not de-ener
izin
or contacts not openin
.
Boiler does not fill or slow to fill. 1. Water supply not on or pressure too low.
2. Line strainer clo
ed.
3. Fill solenoid not malfunctionin
or plu
ed.
4. A Hi
h pressure pocket in the supply line to the boiler causes
the fill solenoid valve not to open. See ”BOILER NOT
FILLING WITH WATER” in “SERVICE PROCEDURES AND
ADJUSTMENTS”.
5. Water level control malfunction. HL-3 relay not ener
izin
or
contacts not closin
to power boiler fill solenoid.
