Action
When lock order is given, if door is not locked after 30 seconds,
machine is stopped and error is visualised.
Also, if unlock order is done, if door is not unlocked after 5 minutes,
machine is stopped and error is visualised.
After 6 minutes filling error is visualised. Then machine is stopped for
10minutes and keyboard is locked. After this time machine will try to
fill again during 6 minutes. This sequence is repeated up to 15 times
or until level is reached. If level is not reached after 15 tries, machine
is stopped.
After 3 minutes trying to drain, error 3 will be displayed. Then the
machine stops and will remain stopped with the door locked until a
power off and power on is executed.
If NTC error is detected (open or short), error 5 will be displayed.
Then, Heating steps will be skipped and heater disconnected.
If temperature does not increase 2ºC in 15 minutes
(only when water temperature is under 50ºC), error 5 will be dis-
played. Heating steps will be skipped and heater disconnected.
Program will not attempt to perform any heating action during the rest
of the program
If the max step time is elapsed without reaching temp, error 5 will be
displayed. Program will continue from next step. If there is any heat-
ing action more, program will try to perform it normally.
If motor is blocked, it is stopped for 30 seconds. After
this, it is tried again. After 3 trials, machine is stopped
and error is visualised.
When tachometer is not detected, motor is stopped for 30 seconds.
After this, it is tried again and motor blocked error is detected. After 3
trials, machine is stopped and error is visualised in the same way as
motor blocked error.
Microcontroller cannot identify what the machine variation is. Possible
EEprom failure.
When detected, ERROR 9 is displayed and the program is aborted.
Also, if motor is turning and door lock is opened, this error is shown
When machine detects a voltage lower than 150V or higher than
264V, machine will stop and visualise the error (E-9). If voltage
returns back to the normal range, machine will continue normally.
When machine is stopped due to this failure, keyboard is locked.
Also, if program has not started, machine will not respond until volt-
age is OK.
