Solly boiler errors: decoding, causes, elimination

The modern arrangement of gas equipment facilitates operation. If one of the parts fails, you do not have to diagnose the entire system. Self-diagnostics of the Solly boiler will give errors on the display before you have time to know about the breakdown. The decoding of the symbols will indicate where to look for the malfunction.

The device, the principle of operation of the boiler Solly

The brand is represented by three series:

  • Solly standard.
  • comfort.
  • First.

The combustion chamber of the Solli double-circuit boiler can be of open and closed type. In the latter case, the fan has a front and rear bearing, which ensures a long service life of the equipment. Some models are equipped with a bithermic heat exchanger. The difference in design in the structure is “tube in tube”. One of them circulates water for the heating system, the other – for hot water in the taps.

The steel burner does not corrode, and the operation of the circulation pump is regulated in three positions. The gas boiler control board is enclosed in a plastic box. It protects it from moisture and heat. Push-button control of the device. The display shows temperature indicators, error codes.

Errors and malfunctions

Incorrect connection and operation, untimely maintenance lead to problems in the operation of equipment. Rarely – factory marriage, low-quality spare parts. As a result, the boiler is blocked, and a code is displayed on the screen. The value can be found in the instructions and our table.

Display codeWhich meansTrouble-shooting
csIncoming thermostat failure.

Check the sensor, its contacts. Tighten the connections to the control board, install a new cable or thermostat if damaged.

Diagnosis required:

  • Heat exchanger. If scale is found, clean with chemical or household products (for example, citric acid solution).
  • pump. Make sure the settings are correct, the tightness of the connections.

Problems with the control module require a call to the wizard.

dh errorIgnition problems.What to do:
  • Turn off the gas supply valve until it stops.
  • Bleed excess air from the system.
  • Clean the burner from soot and soot. Clean the electrode with sandpaper. Move the electrode closer to the flame (from 3 mm) if it has moved.
  • Adjust the fuel supply values ​​on the burner.
  • There is no draft, the chimney shaft is clogged – clean the shaft and pipes.
  • Gas valve failure – install a new element.
  • Check ground connection.

In case of interruptions in the system, you should wait for the supply to be restored.

dyVoltage fluctuations in the network. Deviation from the norm >187 V,Connect the stabilizer to normalize the voltage.
ylThe pressure in the system drops.
  • A leak has occurred. Wait for the circuit to cool, locate the leak and seal it.
  • Filter blockage. Dismantle the filters one by one, rinse from clogging.
  • A leak in the radiator or expansion tank is eliminated by soldering the fistula. If this is not possible, replace.
  • Damage or deformation of the membrane. Install the correct item.
  • Turn on water supply.
fy errorFan operation problems. The blades do not rotate.
  • Clogged pipes, chimney paths, no draft. Clean the entire outlet block.
  • The wiring from the fan to the module is broken. Repair wiring.
  • The fan is out of order, the impeller is stuck. Clean the parts from sticking, install a serviceable assembly.
  • Eliminate power outages by connecting a stabilizer.
  • Hall sensor broken. Change sensor.
  • Incorrect jumper connection to the electronic board. Fix it.
gs errorThe radiator overheated, difficulties in the operation of the pressure switch.

Verify that the temperature sensor and pump wiring is correct. Replace pump if damaged. Clean the filters from dirt.

Clean the heat exchanger from scale. Plaque interferes with the normal circulation of water, so the temperature rises.

syMalfunction of the DHW temperature sensor.
  • Tighten the sensor contacts.
  • Remove scale from the heat exchanger.
  • Troubleshoot the circulation pump. Set it up properly.
  • Control board failure. Call the master.
COProblems with settings.
  • It is necessary to turn on the “Anti-freeze” mode when the room temperature is low.
  • The temperature of the water in the tap does not match the settings. Scroll the knob. Wait until the gas supply is restored.
hsThe temperature sensor on the return line has failed.Diagnose and replace.
lsThe controller on the input line is defective.

Carry out maintenance checks once a year. Clean the radiator and other parts from scale and dirt, monitor the condition of the chimney and the presence of draft. Adjust the boiler according to the instructions. If you are not sure that you can fix the equipment yourself, it is better to contact a service center.
