code
E3 Temperature inside device is too high Heating off - Switch off device and allow to cool down.
E4 Motor or magnetic rods blockage Heating off - Switch off device.
Motor off - Warning! Only to be carried out by authorized service personnel:
Carry out an internal test on the device to check the plug-in connector for the motor.
E11 Break in safety circuit Heating off - Plug in contact plug (N).
- Plug in contact thermometer/temperature sensor.
- Replace faulty connecting cable, plug, or contact thermometer.
E21 Failure in safety circuit test - Switch off and switch on again after about 1 minute.
E22 When fault is indicated again, please contact with IKA ® service.
E29 - Set a higher safe temperature limit.
E24 Surface temperature (Temperature of contr- Heating off - Switch off device until the surface temperature of the heating plate is lower than
ol sensor) of the heating plate is higher than the the selected safe temperature limit.
set safe temperature limit - Set a higher safe temperature limit.
E25 Heating and switching element monitoring Heating off - Switch off device.
- Safety temperature limit > 100 °C
See also “Functional check of inactivating the safety circuit”.
- Warning! Only to be carried out by authorized service personnel:
Carry out an internal test on the device to check the plug-in connector for the heating element.
E26 Difference between temperature of safety Heating off - Switch off device.
sensor and temperature of control sensor - Warning! Only to be carried out by authorized service personnel:
Control temperature > (Safety temperature + 40 K) Carry out an internal test on the device to check the plug-in connector for the temperature sensor.
If the actions described fail to resolve the fault or another error code is displayed then take one of the following steps:
- Please contact the service department;
- Send the device for repair, including a short description of the fault.
