BIO Hydraulic 

Kit

. 

If this alarm occurs repeatedly contact the nearest official 

technical assistance service. 

E-43 

Ashtray full. 

Warning that the ashtray is full. The boiler will continue 

operate normally. To restore warning, the ashtray must be 
emptied and it is necessary to set the “Emptying ashes” 

parameter to 0 of the “User menu” (See “Ashtray status”).  

E-44 

Boiler Maintenance.  

Notice for maintenance of the boiler. Contact your nearest 

official technical assistance service to perform periodic 

maintenance of the boiler. 

E-45

sensing unit. 

Communication failure between boiler and the pellets sensing 

system board (PCB). 
If this alarm occurs repeatedly contact the nearest official 

technical assistance service. 

E-48 

Low fuel level in the hopper. 

Warning that the hopper is going to run out of pellets (fuel 

reserve). The boiler will continue operate normally. Refill the 

hopper with pellets up to the sensor to restore the warning 

alarm. 

E-49 

Hopper is run out of fuel. 

The hopper is completely empty of pellets. The boiler stops 

running to avoid emptying the auger. To restore boiler 

functioning refill the hopper with pellets up to the sensor and 

press RESET button. 

E-50
