DeLonghi Coffee Maker grindstones replacement

Introduction

These instructions show how to replace the grinding stones in a DeLonghi cone grinder. The grinding stones are very similar to those of Jura (and similar in construction). Unfortunately, however, the grinding ring has three flattened sides and is nowhere to be found. The grinding cone from Jura fits, though. So the instructions are only of limited use, e.g. to get spare parts from a grinder with a defective motor, or if the replacement of the grinding cone is already enough. Otherwise, the grinder must be replaced completely, it is not so much more expensive than the grinding stones (eg from Jura) itself.
