INCONVENIENCES TROUBLE SHOOTING
- the fuses or the coil of the respective
contactor are not interrupted
- the pump itself is not blocked, turns in the
wrong direction or has a worn out or broken
impeller.
Insufficient tank temperature
a) make sure that the probes are not damaged.
The value of the probe resistance is given by
the formula:
R = (T x 0,386) + 100) where T is
the measured temperature.
b) make sure that the water supply temperature
is as prescribed
c) check that the fuses and the coils of the
contactor relating to the water resistances are
not interrupted (only for machines with
electric heating).
d) check the correct functioning of the heating
element and that no limestone deposit has
formed.
e) for machines with steam heating check the
steam solenoid valves, the dischargers of
condense and the steam pressure at the
machine. Check the installation of the
condense recovery by detaching the discharge
tube of the steam condense and discharge it
into an open drain. If the pressure at the
manometer is 0,5 bar min. and the machine
starts heating, this means that the problem
concerns the installation of the steam
condense recovery.
