Error 12 - The temperature sensor in the supply line 1 is faulty. Check and repair or replace the flow temperature sensor 2, check and repair the wiring.

 

Error 13 - problems with the temperature sensor. The sensor is broken or damaged in its wiring. Check and, if necessary, replace the damaged part.

 

Error 14 - NTC sensor is not working. The DHW sensor or its wire is damaged. Check and, if necessary, repair / replace the sensor or cable.

 

Error 15 - problems with the outside temperature sensor. The DHW sensor or its wire is broken. Check and, if necessary, repair / replace part or cable.

 

Error 16 is the problem with the return temperature sensor. The return temperature sensor or its wire is damaged. Check and, if necessary, repair / install the new component or wiring.

 

Error 17 - Incorrect modulation current. The value of the modulation current is higher or lower than the set value range.

Error 20 - The gas valve VI is broken. The system receives a signal about the error of the gas valve VI. The gas valve is damaged, its replacement is required.

 

Error 21 - Breakdown of the gas valve V2. The gas valve does not work. Replace it.

 

Error 22 - The system lacks air. The differential pressure sensor can not be switched on. Reset the fault. It is necessary to check the silicone hoses that are suitable for the differential pressure switch. Also check the gas removal system (fan and chimney).

 

Error 23 - The differential pressure sensor is broken. Reset the fault. Check it and replace if necessary.

 

Error 24 - Broken fan. The fan does not reach the required rotation speed for its purging. First check the fan itself and its cables, then unlock the work.

 

Error 25 - Broken fan. The fan does not reach the required rotation speed for operation. First check the fan itself and its cables, then unlock the work.

 

Error 26 - Problem with the fan. The fan runs without stopping. Remove the lock from the fan. Check the fan itself and its wiring. You can remove it by pressing the "reset" button.

 

Error 27 - NTC sensor failure. There is a problem with the NTC sensor in the water heater.

 

Error 30 - Problems with CRC gas condensing boiler Wolf. The EP-ROM of the data group "Gas condensing boiler" does not work. Reboot the system by disconnecting the unit from the power source. If this does not work, then a replacement board is required.

 

Error 31 - Burner failure. Breakage of the EP-ROM of the "Burner" data group. Reboot the system by disconnecting the device from the power source. If this does not help, then the replacement of the control board is required.

 

Error 32 - There are problems with power supply 24 V. The control board needs to be replaced.

 

Error 33 - The factory setting failed. Internal boiler fault. Replacement of the electronic board is required.

 

Error 34 - BCC failed. A problem with the parametric plug. It is required to install a new plug.

 

Error 40 - Problems with the flow switch. There is no signal to turn the flow switch on and off. Make sure that the pressure in the system corresponds to the required pressure. Check the relay itself.

 

Error 42 - The pump responsible for condensate drainage is not working. Possible damage to the pump. There may be problems with the condensate drain line or the pump is not connected to the network. Check the listed modules. If you need to fix or replace.
