PB/PBP51, X20 13.- OVERHEATING ROLL
PB32, X13 ALM / Hot
Ironing temperature higher than the programmed temperature
Probable cause:
Fault in the roll temperature sensors
Fault in the gas valve (machines with gas heating)
Permanent power supply to the gas valve (machines with gas heating).
Procedure:
Close the manual gas inlet valve (machines with gas heating).
The ironer will begin an automatic cooling process.
Once it has finished, disconnect the power supply.
Contact Authorised Technical Services.
PB/PBP51, X20 14, 15, 16.- TEMPERATURE PROBE * ALARM
PB32, X13 ALM / Pro*
Roll temperature control probe open circuit
In models with three temperature probes, the order of the probes is from left to right (front view).
Probable cause:
One of the sensors has an open circuit
Procedure:
Close the manual gas inlet valve (machines heated with gas).
The ironer will begin an automatic cooling process.

PB/PBP51, X20 17 .- TEMPERATURE FAILURE ALARM
PB32, X13 ALM / C
After the heating system has been on for a period of time, it fails to reach the ironing temperature.
Probable cause:
Fault in the gas pressure (machines with gas heating). If a pressure gauge has been fitted at the ironer input,
check the supply pressure.
Insufficient heating power due to a faulty circuit or electrical resistor (ironers with electric heating)
AGA machines only:
Malfunction of relay KA1.
Malfunction of relay KA2.
Fault in the safety thermostat (S10).
Procedure:
Close the manual gas inlet valve (machines heated with gas).
The ironer begins an automatic cooling process.
Once it has finished, disconnect the machine from the power supply.
Contact the Authorised Technical Service or the Authorised Installation Company depending on the ironer
model (depending on type of heating).
