When a fault occurs in the water circulation pump, the power supply of the command module is interrupted and the indicator “pump fault” lights up. When the faults persist, check with qualified technical service.
1.5 Heating
Three heating methods are available, providing the flexibility to adapt the machine to the available energy supply.
•Electrical heating: by several shielded resistors mounted in the heater bath (the number of resistors being in accordance with the power of the machine).
UHM027D UHM033D UHM049D UHM067D
Number of resistors | 6 | 9 | 12 | 15 |
Total power (kW) | 18 | 27 | 36 | 45 |
•Steam heating: through the release of steam pressure delivered by an injector situated in the heater bath.
•Gas heating: by a gas heater that is incorporated in the machine. A pump provides the required water circulation.
The efficiency of the machine is given by the number of stars on the identifying label of the machine, in accordance with the norm
