TROUBLESHOOTING
ALL MODELS
WARNING: CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TESTS OR
MEASUREMENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL
TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER, ATTACH TEST
EQUIPMENT AND REAPPLY POWER TO TEST.
SYMPTOM
POSSIBLE CAUSES
Compartment leaks water around door.
1.
Steamer not level.
2.
Drain line obstructed or not to an open gap drain.
Cold water condenser not operating
properly.
1.
Cold water condenser solenoid inoperative or plugged.
2.
Lack of water supply.
3.
Cold water condenser thermostat malfunction or needs
adjustment.
4.
No power to cold water condenser solenoid.
5.
Plugged spray nozzle.
Steam leaks around door.
1.
Worn gasket - See “DOOR” in “SERVICE PROCEDURES ”.
2.
Damaged gasket.
3.
Drain line obstructed or not to an open drain.
Steam generated inside compartment
when timer is off.
1.
Steam supply solenoid not fully closing (clogged or dirty).
See “FILL AND COLD WATER SOLENOID VALVES” in
“SERVICE PROCEDURES”.
2.
Timer contacts 1 & 3 closed.
Heat coming on without water in boiler
(Dry firing).
1.
Dirty water level probes (shorted to ground).
2.
Retention of water in probe canister assembly.
3.
Water level control malfunction.
Pressure relief valve opening or leaking.
1.
Cycling pressure switch set to high. See “PRESSURE
SWITCHES (GAS AND ELECTRIC MODELS)” in “SERVICE
PROCEDURES”.
2.
Pressure relief valve malfunction.
Base unit will not heat or build pressure.
1.
Check incoming voltage.
2.
Boiler not filled - check fill solenoid for power, clogging or
malfunction.
3.
Water Level Control malfunction.
4.
Water too “pure” for probes to properly conduct electricity.
5.
Contactor malfunction (electric only).
6.
Heating element inoperative (electric only).
7.
Cycling pressure switch open or set too high. Unit is cycling
on high limit.
8.
High limit thermostat open.
9.
Problem with auto blowdown timer (older models).
10. Power switch malfunction.
11. Pressure reducing valve malfunction or needs cleaned
(direct or regenerated units only).
12. Low or no steam supply to unit (direct or regenerated units
only).
