Solution

screw still won't budge – switch off the
appliance, unscrew the nut and switch
it on again choosing any program.
The screw should push out the item
that caused the blockage.
Remove the raw product from the de-
vice and clean all elements thoroughly
before starting a new oil extraction.

pressing.
Wait 30 minutes until the Wartmann®
nut oil press is cooled off. Then

socket for at least 10 seconds. Retry.
Immediately take the plug out of the
socket, let the Wartmann® nut oil
press cool down and have it repaired.
