12:9 HEAT PUMP LOW PRESSURE
The error code is shown if the input HP LOW PRESSURE (low pressure switch for heat pump)
has been deactivated.
The error code can be trigged if there is too little refrigerant in the heat pump or by damaged wiring
or connectors. This error can also be trigged if machine is started in a cold environment.
The error can be reset from the control system when the pressure is restored and the ongoing
program will continue. If error is not possible to reset or repeats see below.
Recommended actions:
1. Check the harness, connectors and functions by reading the electrical schematic and by using
the SHOW INPUTS menu when the machine is in service mode.
2. Try to run again, if error still present, check the heat pump for gas leakage.
12:10 HP HIGH PRESSURE CHECK COOLING SYSTEM AND FILTERS
The error is activated if the input HP HIGH PRESSURE (high pressure switch for heat pump)
has been deactivated.
The errror can be trigged if there is no cooling water to machine or if the airflow is obstructed,
by lint, overload, etc.
The error can be reset when the pressure has dropped below restart level.
Recommended actions:
1. Check the harness, connectors and functions by reading the electrical schematic and by using
the SHOW INPUTS menu when the machine is in service mode.
2. Check cooling water supply.
3. Check airflow and clean filters.
12:11 DRYING ERROR WITH RMC PROGRAM
The error code is shown if the analog input RMC does not register the STOP VALUE FOR RMC
PROGRAM reached within the maximum drying time (normally 90 minutes). When the error is
trigged the machine will automatically go to the cooling module before the program ends.
The error code is reset from the control system by a short press on the control knob/start button.
A long press on the control knob/start button will make the control system reset and ongoing
program will be ended. If the clothes are still wet after maximum drying time and the dryer is not
overloaded, check that the heating system is working correct by using the ACTIVATE OUTPUTS
menu when the machine is in service mode.
Note!
Make sure that the fan is active before turning on the heat.
If the clothes are dry, check the RMC system and harness, connectors and functions by reading the
electrical schematic and by using the SHOW INPUTS menu when the machine is in service mode.
• RMC value no load = 0%
• RMC value 100K Ohm between lifter and drum = ~24% (Putting your hand over the lifter onto the
drum will result in approximately 20% RMC value)
• RMC value system short circuit = 50%
