E MW: magnetron alarm. Only the generation o the microwave will be stopped. The oven can cook in the

traditional way. Enter in programming mode and check the value of parameter ALmg. See parameter list to

understand which magnetron/s was/were faulty. Set to 0 the parameter ALmg.

E SL: boiler water level probes always in closed circuit. They continuously detect the presence of water.

Parameter ALFn has to be reset to 0 to restart the oven.

ECLO: clock error. It appears if the clock was never adjusted.

E PWM: Communication error with PWM system

Ecup: Reset of cavity burner (gas oven) (the upper one in the 20 grid ovens)

Ecdw: Reset of lower cavity burner (gas oven) in 20 1/1 and 2/1 ovens

Ebup: Reset of boiler burner (gas oven) (the upper one in 20 2/1 ovens)

Ebdw: Reset of lower boiler burner (gas oven)

Ertc: A component of the PCB is not dialoguing (Real time clock problem)

Eram: problems to read the RAM

Epar: parameter alarm on the EEPROM. Impossibility to read/write parameters

Epix: problem on the program index of the Factory recipes in the EEPROM

Epha: problem on the program phase of the Factory recipes in the EEPROM

Edes: problem on the description of the factory recipes in the EEPROM

Efau: problem on the automatic recipes in the EEPROM

Warnings

EH2O: Before the starting of the cleaning system and during its working, there are some check points of

the water pressure. If the water pressure is too low this warning message appear on the display. Check

the water pressure (1.5÷2.5 bar), check the correct working of the water pressure switch, check if there are

obstructions on the cleaning water inlet pipe (its inner diameter must be 20 mm). From firmware release

2.50, EH2O is a warning message and no more an error causing the stopping of the cleaning cycle.

EFLP: Cavity ventilation flap failure; check the motoreducer or the micro switch that detects the close

position of the flap. If the motoreducer does not close the flap within the time set in parameter FLto, EFLP

error appears.

EPrG: Error in reading the phases of a multiphase recipe

The following warnings are showed by an icon on the top right side of the screen:

Safety level probe of the boiler out of water

Preheating phase of the boiler
