TROUBLESHOOTING

EXTREMELY SLOW COOKING TIME

If the cooking time is abnormally slow then the difculty
may be due to insufcient steam pressure. First deter-

mine that pressure on incoming stream line at kettle is
with in 15 PSI of rated kettle pressure. Note that pressure
approaching the rated kettle pressure are liable to set off
the safety relief valve. If required pressure is available

to kettle, then possibly volume of steam is not sufcient.

Minimum 3/4” pipe size is required to the kettle but if the
steam generating source is at a great distance from the
kettle, larger pipe will be required. Finally, the core of the

steam ow will require disassembly and inspection.

PUMPS: PUMP MAKES EXCESSIVE NOISE

1. Check for vacuum leaks in the suction line.

2. Check alignment with drive mechanism. Misalign­ment will cause wear and subsequent high noise
level in operation.

3. Check compatibility of uid being pumped against
manufacturers recommendations.

4. Relief or unloading valve set to high.

5. Aeration of uid in reservoir, return lines above uid
level.

6. Reversed rotation.

7. Plugged reservoir lter breather.

EXCESSIVE PUMP WEAR

5. Abrasive dirt in the hydraulic oil being circulated
through the system.

6. Oil viscosity too low.

7. System pressure exceeds pump rating.

8. Pump misalignment.

9. Air being drawn in through inlet of pump.

DIRTY OIL

1. Components not properly cleaned after servicing.

2. Inadequate screening in ll pipe.

3. Air breather left off.

4. Filter dirty or ruptured.

SOLENOID VALVE: FAILS TO OPERATE

1. Is there an electrical signal to the solenoid or oper­ating device? Is the voltage too low. Check with the
volmeter, test light in an emergency.

2. Has foreign matter jammed the main spool? Remove
en caps and see that main spool is free in its move-

ment. Remember that there will be a quantity of uid

escaping when the cap is removed and provide a
container to catch it.

8. Oil viscosity too high or operating temperature too
low.

9. Loose or worn pump parts.

10. Pump being driven in excess of rated speed.

11. Air leak at pump shaft seal.

12. Oil level too low and drawing air in through inlet pipe
opening.

13. Air bubbles in intake oil.

PUMP PARTS INSIDE HOUSING FAIL TO OPERATE

1. Seizure due to lack of oil.

2. Excessive system pressure above maximum pup rat­ing.

3. Excessive torquing of housing bolts.

4. Solid matter being drawn in from reservoir and
wedged in pump.

3. Are solenoids improperly interlocked so that a sig­nal is provided to both units simultaneously? Put test
light on each solenoid lead in parallel and watch for
simultaneous lighting. Check electrical interlock. this
condition probably burns out more solenoids then
any other factor.

4. Is uid media excessively hot? Check for localized
heating which may indicate an internal leak, Check
reservoir temperature and see if it is within machine

specications.

5. Voltage too low? If voltage will not complete the stroke
of alternating current (AC) solenoid will burn out coil.

6. Signal to both solenoids of a double solenoid valve si­multaneously. One or both of the solenoids will be un­able to complete their stroke and will burn out. Make
certain the electrical signal is interlocked so that this
condition cannot exist.
