HEATING UNIT
Replace the electric heating element if it becomes faulty or malfunctions.
•
Do not replace the heating element with a more powerful one. Before making any changes,
please contact the Manufacturer.
•
If the thermostat of the heating element is triggered, reset it by pressing the central button
of the thermostat. However, before starting the machine up again, check what caused the
problem.
•
If the heating unit insulation needs to be removed, restore the insulation after the mainte-
nance work has been completed.
•
Remove and clean the heating unit level probes.
•
Check whether there is any limescale build-up on the heating element.
•
If there is a lot of limestone build-up, this indicates that the water filter has not been replaced,
or that the softener has not been regenerated.
•
When replacing any components, always replace the relative gasket as well.
X
SAFETY VALVE
SCNR VALVE
Check that the safety valves and non-return drain valves are operating properly, as indicated
in par. 8.3.5 - 8.3.7.
If these need to be replaced due to malfunction, repeat the check with the newly-installed valve.
X
HYDRAULIC CIRCUIT
•
Check whether there is any limescale build-up in the hydraulic circuit.
•
When replacing any components, always replace the relative gasket as well.
•
If there is a lot of limestone build-up in the machine's hydraulic circuit, this indicates that
the water filter has not been replaced, or that the softener has not been regenerated.
•
Take care in areas where the water is very hard. The water filter will need to be replaced
more frequently and the water softener will need to be regenerated more often, especially
if the machine is used intensively
X
