A buzzer will sound for 3 seconds when the
“Maximum water level”
is reached to
indicate that the tank is full. If you do not hear the signal, excess water will flow out from
the filler.
•
If the alarm is displayed during a cycle,
fill the tank and proceed as shown in the
INSUFFICIENT STEAM ALARM procedure. Furthermore, check and replace the
clean
water tank 10
level probe insulation.
Insufficient steam alarm
This alarm indicates leakage of steam from
chamber 09
.
The alarm may appear during a cycle, when the suitable pressure needed to run a cycle is
not reached at a temperature of 114°C. Pressure is detected by transducer 38 and
temperature by chamber temperature probe PT1 39.
•
Check the efficiency and cleanliness of the
chamber gasket 31
and of the flange of
chamber 09
on which it is fitted. Replace if damaged.
If leakage of steam is found, adjust the door closing as shown in chapter DOOR
ADJUSTMENT.
•
Check correct operation of the
pressure transducer 38
and
temperature probe PT139
using an appropriate measuring tool
.
•
Check the internal coil of the
steam generator 47
.
•
Check that the total weight of the load is not exceeded (see USE AND MAINTENANCE
MANUAL, chapter OPERATING USE).
•
Check the steam solenoid valve
EV4.
•
If the alarm is not resolved after these checks, check drain solenoid valve
EV2
(see
diagrams). This is connected to the chamber drain and is the first solenoid valve to
intercept the steam. For this reason, it might need to be replaced.
Replace the solenoid valve when time or number of cycles
shown in the Scheduled service table is exceeded (see USE AND
MAINTENANCE MANUAL, chapter MAINTENANCE). Proceed as
follows if cleaning is required:
-
Remove the solenoid valve keeping track of the
sequence of parts in order to refit them correctly
-
Carefully clean the hole in the valve body
(A)
;
-
Carefully clean the core
(B)
. The gasket pushed by the
spring
(C)
should slide smoothly inside. Should the gasket
be deformed, the solenoid valve will need to be
replaced.
