PROBLEMS TROUBLE SHOOTING
c)make sure that no dirt has accumulated in
the solenoid valve. This defect causes the
machine to fill also when the main switch is
switched off.
d)in case the tank remains full for many hours
(e.g. during the night) the machine might
continue to fill. Therefore empty the machine
completely and refill it.
e)check that the air trap is in a vertical
position.
Insufficient wash results
a)make sure that detergent equipment is
working and is suitable for commercial
dishwashers and that the concentration of the
dosing is correct
b)make sure that the dispenser of the
detergent is not empty and that the detergent
injector functions correctly
c)make sure that the wash jets are not
blocked, clean them if required.
d)make sure that the temperature in the
prewash and wash tank are correct.
e)make sure that the plugs of the spray arms
are fitted correctly
f)if the pump is not running; check the
following:
- the overload relay of the motor protector has
not excluded the respective pump; in this case
reset it (this fault is signalled by the lamp
"H03" being illuminated)
- the coil of the relevant contactor are not
faulty
- the pump itself is not blocked, and is not
going in the wrong direction or has a worn or
broken impeller.
