This guide presumes a basic knowledge of how the machine functions. If this is 

not the case always read the instruction manual to better understand the correct 

function of the machine so that the actual malfunction becomes readily identifiable. 

Before attempting to repair a machine gather as much information from the 

customer as possible. Always ask for a clear and detailed description of what the 

machine does or does not do. Many problems can be resolved on the phone or 

by email. This avoids machine downtime and costs and helps to reach the best 

possible customer satisfaction!

deposits can be responsible for faulty functioning. These instructions cannot warranty
