TROUBLESHOOTING.
Food does not cook uniformly. The food portions are not equal in size and/or the liquid-to-food ratio is
too low.
No or insufficient heating. Allow for sufficient time for the cooking temperature to stabilize when the
cooking temperature is increased. Check to see if the heating icon is flashing. If it is not flashing, check
that the Safety Set temperature and the Software High Limit temperature are higher than the cooking
temperature set point and/or that the cooking temperature set point is higher than the cooking liquid
temperature. If the icon is flashing, check for scale or mineral deposits on the heater.
No or insufficient circulation. Check the cooking liquid level to be sure the pump head is covered with
fluid. Check the Pump Speed Switch on the rear of the Controller to make sure that it is at the desired
speed and is not in between settings. Check the pump impeller for blockages and clean as required.
Cooking temperature set point cannot be maintained. Allow time for cooking liquid to stabilize at the
desired temperature and verify that the reservoir cover is in place.
Digital display is blank. Verify that the power cord is plugged into an operating electrical outlet and that
the Power Switch on the rear of the unit is in the “ON” position. Check for problems with the main
electrical power supply (tripped circuit breaker, etc.).
E-H1 appears on the display. This indicates that the value entered for the Software High Limit
temperature is below the current cooking temperature setting. Either lower the cooking temperature
setting or enter a higher Software High Limit temperature value.
FLt1 appears on the display. This indicates that the Software High Limit value has been exceeded.
Increase the Software High Limit value and then turn electrical power “OFF” and then back “ON” using
the Power Switch on the rear of the unit.
FLt2 appears on the display. This indicates that the EEPROM needs to be reset. Place the Power
Switch in the “OFF” position and then press and hold the P3 Button while returning the Power Switch to
the “ON” position.
FLt3 appears on the display. This indicates that the Safety Set temperature has been exceeded. It may
be caused by a low liquid level, a cooking temperature setting and/or liquid temperature higher than the
Safety Set temperature, or a Controller failure. Check the fluid level in the reservoir and replenish as
required, check the cooking temperature set point and adjust it or the Safety Set temperature as required.
If problem persists, contact PolyScience.
FLt4 appears on the display. This indicates a triac failure or electrical line interference. Connect the unit
to another electrical power source; if problem persists, contact PolyScience.
FLt5 appears on the display. This indicates a temperature sensor failure. Contact PolyScience.
