7.1 Inspection and maintenance intervals
Appropriate, regular inspections and maintenance and the
exclusive use of original spare parts are the decisive fac-
tors in determining whether your Vaillant ecoMAX 646
will run problem-free and have a long service life.
Danger!
Inspections/Maintenance work not carried out
can result in material damage and injury to per-
sons.
For this reason, we recommend the signing of an inspec-
tion and/or maintenance contract. The inspection is in-
tended to determine the actual condition of an appliance
and compare it with the specified condition. This is done
by measuring, checking, observing. Maintenance is re-
quired in order to eliminate any deviations of the actual
condition from the specified condition. This is usually
done by cleaning, setting and, if necessary, replacing in-
dividual components subject to wear. With regard to the
Vaillant ecoMAX 646, this means it is usually sufficient
to conduct an inspection once a year. Inspections can be
performed quickly and economically without dismount-
ing any components thanks to the data query in the
DIA system, easy optical inspection and an air ratio
measurement. Experience indicates that under normal
circumstances it is not necessary to clean the burner
and heat exchangers yearly. These maintenance inter-
vals and their extent are determined by a specialist,
depending on the ascertained condition of the appliance
during the inspection. All inspection and maintenance
work should be performed in the order specified in
table 7.1.
7.2 Inspection and maintenance instructions
Only genuine Vaillant spare parts may be used for in-
spections, maintenance and repair work to ensure the
perfect long-term working order of all functions of your
Vaillant appliance and to prevent the permitted series
condition from being changed. Any spare parts which
might be required are listed in the relevant current spare
parts catalogues. Information can be obtained from
Vaillant Customer Service Centres.

If inspection and maintenance work is neces-
sary with the mains switch on, this is indicated
