KETTLES, MODELS EL-20F TO EL-60F, EP-20F TO EP-60F
9.0 TROUBLESHOOTING (Continued)
9.2 EXTREMELY SLOW COOKING TIME
1. If the cooking time is abnormally slow, then the difficulty may be due to air being present in
the kettle jacket. To remove air, follow AIR VENTING INSTRUCTIONS.
2. If the kettle will not reach and maintain Pressure Gauge zone in the green area on the
gauge when cold, a slow leak may have developed in the jacket. Check all fitting
connections to jacket including the heating element gasket. Tighten or replace if necessary.
3. Slow cooking time may also be due to a burnt out heating element. Test elements and if
defective, replace complete element assembly.
9.3 KETTLE WILL NOT OPERATE WHEN TURNED ON
1. Check that power supply is available to kettle.
2. Kettle will not operate if water level is inadequate in jacket. Follow LOW WATER LEVEL
instructions.
3. If water level is sufficient and kettle refuses to operate, then check that Tilt Interlock Switch
in Console is fully engaged when kettle is in its normally upright position. Adjust Retaining
Tilt Collar if necessary to assure complete contact with switch and if kettle still does not
operate, then check for defective switch and/or loose wiring connections.
4. When Thermostat Knob is dialed and TEMPERATURE indicator light does not come on,
then it may be due to either a defective Thermostat or loose wiring connection(s).
5. Check that the Contactor(s) are being energized and power is being made available to the
heating elements when thermostat is dialed. Replace defective Contactor(s).
9.4 DRAW-OFF VALVE LEAKS
If leak occurs through the valve stem, replace the "O" ring. If the leak is caused by faulty
sealing between the stem disc and valve seat, this can be corrected by cleaning off dried on
food residue with an extremely fine emery cloth. If the vulcanized rubber stem piece has been
damaged, it must be replaced.
