Error messagesTroubleshootingDisposal 18Page 35Mains fuseis activatedCryo 6 is fitted with a bipolar overload protection element integrated into the mainswitch (10) to protect the device in the event of supply problems. If the fuse trips, thedevice automatically switches off via the toggle switch (10). The device can only bemade ready for use again by switching it on via the toggle switch (10).Please notify the customer service department if this fault occurs frequently.Reduced cold airoutput / reduction incold air outputDirt in and around the defrost opening (8) may be the cause of a significant reductionin cold air output and a weak air stream. Dust particles are deposited in the heatexchanger by the treatment air. This can eventually lead to blockage of the defrostopening and a build-up of defrost water.The defrost opening is located above the defrost water container. The device mustbe defrosted before cleaning the defrost opening (see page 18, “Performingdefrosting”). After defrosting, switch off the device and remove the plug from thesocket.Remove the defrost water container and place a flat container underneath the deviceto capture the defrost water. Slowly pull out the defrost opening, using a twistingmotion.Clean the defrost opening under running water and screw it back into place.Error messages Device components that are important to the running of programs are tested whenthe device is switched on and sometimes also when it is in use. If an error isdetected during these tests, treatment is terminated, and an error message isdisplayed in the top line of the display and an acoustic signal is produced.Error messages are shown in plain text in the top line of the display. Treatmentcannot be continued, the device can only be switched off.Errors that do not affect continued work with the device can be resolved by switchingthe device off, waiting for five seconds and then switching it back on.If the error message relates to excessively high temperature or pressure, you shouldwait for 30 minutes before switching the device back on as the device needs time tocool down. These error messages may be caused by high external temperaturesand room temperatures which impair cold air output.OK Start/ StopExcess pressure cold circuit
