To help find the exact issue with your boiler, please let me know: What is currently showing on your LCD display?
| Complaint | Possible Cause | Troubleshooting Steps | | :--- | :--- | :--- | | | • Three-way valve stuck in DHW position • Heating circuit sensor (NTC) faulty • Air in the system or pump seized | 1. Check if you are in "summer mode". If so, switch to "winter mode". 2. Bleed any trapped air from your radiators. 3. If the problem persists, the three-way valve, pump, or sensors may need professional replacement. | | No Hot Water, but Heating Works | • Faulty DHW flow sensor/turbine • Plate heat exchanger blocked • Faulty DHW NTC sensor | 1. This is likely a professional issue. The DHW flow sensor is a common failure point. 2. A service technician can diagnose and replace the faulty component. | | Boiler Frequently Turns On and Off | • Boiler is short-cycling due to being oversized for the heating demand • Faulty thermostat • Clogged system water filter or radiator sludge | 1. Check if the room thermostat (if installed) is functioning correctly. 2. Ensure all radiator valves are fully open to allow proper water flow. 3. A technician may need to adjust boiler parameters, clean filters, or power-flush the system. | | Fluctuating Water Temperature | • Faulty DHW NTC sensor • Plate heat exchanger partially blocked with limescale • Inconsistent gas supply pressure | This issue typically requires a professional. A technician will test the sensor, descale or replace the heat exchanger, and check the gas supply. | | Radiators are Not Heating Evenly | • Airlocks in the system • Sludge/debris buildup in radiators • Imbalanced system (need to balance radiator valves) | 1. Bleed all radiators to release trapped air. 2. If some radiators remain cool at the bottom, they may have sludge buildup and require a professional power flush. 3. If the issue persists, a technician can "balance" the system to ensure even heat distribution. | | No Display or Boiler Unresponsive | • No power to the unit • Tripped circuit breaker • Blown internal fuse • Faulty main board | 1. Check your home's electrical panel for a tripped breaker and reset it. 2. Ensure the boiler's main power switch is turned on. 3. This often indicates a need for professional electrical diagnosis. |

Note: If the error reappears immediately or happens multiple times a day, do not keep resetting it. Turn off the gas supply and contact a certified HVAC technician. Maintenance and Safety Rules
The "FI" in Lambert LX 24 FI means electronic injection. A lean mix (too much air, not enough fuel) causes extremely high combustion temperatures.
This model is part of a family that includes the Baymak Digitech 24 Fi and Falke Fx 24 Fi, with which it shares many operational features. If your Lambert LX-24 FI is a fuel-injected
To keep your Lambert LX 24 Fi operating legally and safely, adhere to the manufacturer's operational policies:
Locate the knob marked with a faucet icon. Turn it clockwise to increase the water temperature and counterclockwise to decrease it. For optimal comfort and safety, it is recommended to keep domestic hot water between to prevent scalding and reduce limescale buildup. 3. Adjusting the Central Heating Temperature
Check the manufacturer’s website (Lambert is often a brand sold in Eastern Europe; parent companies may include Protherm, Dakon, or Vaillant). If unavailable, search for “Lambert LX 24 FI návod na obsluhu” (Czech/Slovak for user manual).
The boiler cannot safely distribute heat without adequate hydraulic pressure.
