Error Codes

Errors E01 through E04 are heating errors. Error Handler
will lock out heating functions if heating error is detected.
Stirring functionality is unaffected. Error E05 is stirring
error. Error Handler will lock out stirring functions if stirring
error is detected. Heating functionality is unaffected.
Error E08 is failure of temperature or speed knob, Error
Displayed Intended to Detect
Message
E01 Internal thermocouple out
of range.
E02 Excessive top heat-up
time.
E03 External probe left out of
solution or out of range
E04 Over temperature
condition detected by
electronic circuit.
E05 Motor system failure.
E08 Knob failure

Troubleshooting

Handler will lock out both heating and stirring functions
if it is detected. If the condition that caused the error is
no longer present, for E01, E03(out of range) and E05,
the unit will clear the errors automatically, for E03(out of
solution), rotating temperature knob to OFF position or
turning off the switch on the left side of the unit will clear
the error, and for E02, E04 and E08, only unplugging the
unit will clear the errors.
Cause
Internal thermocouple not connected.
Thermocouple open.
Thermocouple connected backwards
(reversed polarity).
Internal thermocouple short circuit.

External probe left out of solution.
Failure in external probe.
Internal thermocouple temperature is
above the Over Temperature Protection
triggering
value .
Locked rotor condition.
Failure in motor.
Failure in motor circuit.
Failure in motor sensor.
Failure in temperature knob or speed
knob.
