DRAWBACK POSSIBLE CAUSES AND REMEDIES
Tank temperature insufficient
a) check that the thermostat is not faulty or
not calibrated.
b) check that the temperature of the feeding
water is in the range from 50°-0/10°C, as
specified.
c) check that the thermostat is set to the
right temperature and operates correctly.
d) check that the coil of the remote control
switch for the tank heating element is not
broken (this is for electric heating machines
only).
e) check that the heating element is working
correctly
Insufficient rinsing Prior to checking the rinsing system make
sure that the washing system operates
correctly, because a good rinsing also
depends on a correct washing. Having
ascertained that the washing works
correctly, check that:
a) the dynamic pressure of the feeding
water is between 2 and 4 bar.
b) the jets are not clogged by calcareous
residuals.
c) solenoid valves operate correctly.
d) the water inlet filter is not clogged.
e) the boiler is not scaled to such an
extent as to limit the water flow rate.
Insufficient rinsing temperature Check that:
a) the thermometer is not broken
or not calibrated.
b) the temperature of the feeding water is in
range from 55° to 65°C, as specified.
c) the dynamic pressure of the feeding
water is between 2 and 4 bar.
