What to do if my Radiant RK 18 OV shows a flame detection malfunction?
- J
  Jody SalazarAug 13, 2025
  A flame detection malfunction in your Radiant Boiler can be attributed to a few reasons. The ionisation electrode may be malfunctioning, in which case you should clean it or replace the part. Another cause could be a malfunctioning ionisation electrode cable, which would require replacing the part. Lastly, the printed circuit board itself may be malfunctioning, also requiring a replacement.

How to fix a tripped safety thermostat (95°C) in a Radiant RK 18 OV?
- J
  Jennifer ThomasAug 20, 2025
  If the safety thermostat (95°C) has tripped in your Radiant Boiler, the thermostat itself might be malfunctioning or out of calibration, which means it needs to be replaced. Another possibility is a disconnected thermostat cable, so you should check the wiring.

  Tamara JohnsonAug 25, 2025
  If there's no water in your Radiant Boiler system, it might be due to insufficient water pressure (stopping at 0.3 bar), so you should fill the system. It could also be caused by a disconnected water pressure switch cable, so check the wiring. Another potential cause is a malfunctioning water pressure switch, which would require replacing the part.

What causes a heating sensor issue in a Radiant RK 18 OV?
- A
  Andrea PorterAug 28, 2025
  A heating sensor issue in your Radiant Boiler can occur if the sensor is malfunctioning or out of calibration (resistance value 10 kOhms at 25 °C), so you should replace the part. Another cause could be a sensor cable that is disconnected or wet, in that case you should check the electrical connection.

Why is there no flame in my Radiant Boiler?
- A
  Amanda HowardNov 15, 2025
  The absence of a flame in your Radiant Boiler may stem from several causes. It could be due to a lack of gas supply, so check the mains supply. Alternatively, the ignition electrode might be broken or earthed, necessitating a replacement. A malfunctioning gas valve could also be the culprit, which would also require replacing the part. In some cases, the mechanical minimum adjustment or slow ignition adjustment on the gas valve may be set too low, requiring regulation. For LPG boilers, the gas valve inlet pressure might be too high, so check the maximum pressure setting. Incorrect wiring of the power supply (live and neutral wires inverted) can also prevent ignition; ensure the wires are connected correctly. Lastly, a malfunctioning ionisation electrode or a disconnected ionisation electro...
