A - Check that the thermostats are effective and calibrated .
B - Check that the temperature of the feeding water is from 50° to 60° C, as specified .
C - Check that the thermostats relevant to the tanks are set to the right temperatures and
operate correctely .
D - Check that the fuses and the coil of the remote switch are not broken .
E - Check that the heater elements are effective .

10 - Rinsing insufficient
An effective rinsing also depends on correct washing operations . Therefore, prior to checking
the rinsing system, make sure that washing took place correctly, and specifically look at item
X in the respective paragraph. Having ascertained that washing was made correctly, check
that :
A - The dynamic pressure of the feeding water is not less than 2 bars. Should the pressure
be insufficient, install rinse buster pump M07 in order to increase pressure .
B - The nozzles are not clogged by calcareous residuals and they are oriented to the right
direction .
C - Water inlet solenoid valve EV1 operates correctly.
D - The water input filter is not clogged
E - Energy-saver microswitch FCE1 and FCP9 are effecteive .
F - The curtain of the last tank is in the right position and does not cover the rinsing nozzles
when dishes pass there .
G - The boiler is not scaled to such an extent as to limit the water flow rate.
11 - Insufficient Rinsing temperature
The temperature of the rinsing water should range from 80° to 90° C.
Should it be lower.check that :
A - The thermometer is effective and calibrated .
B - The temperature of the feeding water ranges from 50° to 60° C specified (excluding
machines with drain heat recovery unit) .
C - The dynamic pressure of the feeding water does not exceed 2 bars. If so, calibrate the
pressure reducer incorporated in the machine.
D - The rinsing nozzles have not been unduly widened or replaced.
E - The thermostats relevant to boiler CT2 is set to the right temperature and operate
correctly.
If the drawback is not due to any of the causes listed hereabove,proceed as follows :
