Leaks
Faults that are plainly due to incorrect operation or inadequate maintenance may not be dealt with under the guarantee. Appropriate instructions for use and maintenance may be
found in the specified chapters of the instruction manual (IM) and brief description (BD).
Experience shows that, when recording a fault report it is important to establish not only the symptoms observed but also the circumstances in which the fault occurs.
•
Is the problem present all the time, does it occur sporadically or at specific intervals?
•
Does its occurrence date back to a specific event (change of detergent, ...)?
To avoid repeated repairs it is important to establish the actual cause.
