Malfunctions, warning and error messages
Live components may be exposed once the covers have been removed. Touching
these can lead to an electric shock. Malfunctions requiring work inside the appliance
may only be recti
fi
ed by electricians. Observe the separate service manual for this.
Do not try to rectify appliance errors yourself but contact the MEMMERT customer ser-
vice department or an authorised service point.
In case of enquiries, please always specify the model and appliance number on the
nameplate (see chapter 2.7).
