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.
