When a technical problem occurs, the user hurries to call the wizard. In modern Proterm Panther boilers, errors on the display notify the consumer about the problem. Each code indicates the cause of the breakdown, and when decrypted, you can find out how to fix the problem. If your instruction is lost or unclear, refer to our table.
The technique is presented in several series. We will tell you more about the most popular releases:
Did you notice a message on the screen of the gas boiler? Do not be afraid: understand the reasons for its appearance. Experts recommend first restarting the equipment. If the code has not disappeared, then see the value in the table.
- Turn on water supply.
- Check pressure readings, set correctly.
- Inspect connections for leaks.
- Diagnose the pressure sensor.
F1 No flame. Ignition blocked, fuel valve closed.
- Carry out diagnostics and replacement of the ionization sensor, its contacts with the electronic module.
- Open the gas cock at full power, restart the equipment. Reverse the plug in the outlet by reversing the polarity.
- Restart the thermostat.
F2 The temperature sensor is defective. The temperature dropped to +3 °С. Install a working temperature sensor. Or start the appliance in winter mode and wait for the values to increase. F3 Overheating has reached 95°C. The security system disabled the device. Let the boiler cool down and restart. If the problem persists, reset the fuse. F4 The DHW temperature sensor is broken. In this case, the boiler works for heating, but does not switch to domestic needs. Replace sensor, clean contacts. F5 The outdoor thermostat is out of order. Inspect the thermostat circuit, install a new element. F6 No communication with flue gas sensor. Repair the contacts between the sensor and the main module. Replace defective part. F7 Wiring problems. The break could occur in any part of the system. This means that one of the elements does not receive a signal to the module. Check all wiring, including control board. F8 The temperature sensor and water heater ground circuit is open. Tighten the contacts or install a working sensor. F10 Thermistor short circuit. If the cause is the thermistor, I will replace it. It is possible that the voltage dropped to 0,40 V. Or a short circuit occurred in the plug of the device. Then do the repair. F15 Reverse draft controller shorted. Disassemble the device, clean the terminals. The element is located on top, near the fan. Clear its pipes from blockage. F20 The temperature limiter has tripped.
Perhaps the connection was not made correctly, so the values uXNUMXbuXNUMXbhave reached a critical level. Damaged wiring requires repair.
Also bleed the air from the system, make sure the pump is working.
F22/F75 Pressure dropped to 0,3 bar. Change pressure sensor. Adjust the circulation pump. Remove dirt from its parts. Open the feed valve, make sure that the structure is not leaking. F23 The temperature limit between the supply and return lines has been exceeded. Diagnostics in progress:
- Pump.
- Automation, sensors.
F24 Insufficient water level. The pump is blocked, so little liquid is pumped. Open the inlet valves, bleed excess air and repair broken parts. F25 Air circulation is disturbed, the protection has turned off the boiler.
The flue pipe is leaking. Tighten all connections tightly, otherwise carbon monoxide will enter the room.
Conduct an inspection:
- Fan work.
- Smoke outlets. It should not be blocked by foreign objects, debris.
- control module
F28 Extinguishing the flame after ignition.
Reconfigure the fuel supply system. Restart boiler.
Carry out diagnostics of the ionization sensor, cleaning the contacts.
Reverse the polarity of the plug by reconnecting it to the outlet.
Clean the ignition unit.
F29 Flame went out during operation.
Interruptions in gas supply. Wait for recovery or contact the gas service.
Check ground line.
Remove dirt from burner. Remove the casing of the device by unscrewing the bolts, remove dust, soot from the ignition elements.
F33
The system freezes. The blocking has worked. Remove snow and ice from the chimney if they have accumulated during the winter. If the fan is working properly, the pressure switch rings, in the event of a breakdown, a new element is required. F55 Flue gas controller has failed.
If contactors and relays stick, clean the parts with fine sandpaper.
In case of malfunctions in the control module, contact a specialist.
F62 Gas valve broken.
Disable and enable the device. Make sure there is no fuel leak. Lubricate the joints with soapy water. If bubbles appear, call repairmen.
Clean the valve.
F72 Return line and flow sensor give different readings. Make a diagnosis:
- Electronic board.
- Circulation pump.
- Sensors.
Radiator clogged up. For purification, special reagents are used. You can use home remedies, a solution of citric acid.
Check the filter for blockage.
F73 The pressure controller is defective. Reconnect the part, tighten its contacts. Replace if open or shorted. F83 There is no coolant in the system, heating does not occur during ignition. How to proceed:
- Add water.
- Inspect the expansion tank and other connections for damage and leakage.
F84 NTC2 and NTC5 sensors give different readings. Make a call and replace. F85 Supply and return sensor not working.
Following the recommendations, you will independently cope with the problem and continue the successful operation of gas equipment.
