Has heating equipment been blocked? The system probably crashed. How to fix the problem? The error codes of the Vesten boilers will help you. The self-diagnosis system scans all nodes and reports breakdowns of the control board. As a result, digital symbols appear on the scoreboard. Their decoding indicates the cause of the malfunction.
Features of Westen boilers
The most popular models are Westen Pulsar and Westen Quasar. These are wall gas boilers with two circuits. One circuit is responsible for the heating system, heating the area to 180 m², the other - heats the liquid for hot water supply (DHW).
The Westen Pulsar design includes a circulation pump, so the coolant moves along the circuit forcibly. The implement program uses automatic summer mode switching. In the warmer months, the heating circuit switches off together with an external thermostat. Also, the appliance does not start heating when night falls.
The boiler has a closed combustion chamber, smoke is forced off by a fan. Requires additional network connectivity. The coefficient of performance is 91%. Productivity reaches 9 l / min.
Westen Quasar connects to the same floor heating system. An open combustion chamber requires connection to a stationary chimney shaft. To maintain the flame, air is taken from the room, so good ventilation is necessary. Efficiency - 90%.Protection against freezing, overheating, lack of traction is provided.
Errors and malfunctions
You can find the values of the error codes in the operating instructions, as well as in the table below. First restart the boiler to clear the problem. To do this, hold the R button. Did not help? Then you need to look for the cause of the malfunction.
Error Codes | What do they mean | How to fix a breakdown |
E01 | Ignition does not occur. |
|
E03 | The thrust sensor has triggered. | What to do:
|
Throws error E10 (a triangle in a circle with an exclamation mark on the screen) | There is no connection with the hydraulic pressure switch. |
|
E25 | The coolant does not circulate well. | How to fix the situation:
|
E35 | Spurious flame detected. |
|
E97 | Unstable power: possibly power surges. | Rebooting the system. Connect a voltage regulator. Repair or replace the electronic board. |
Other issues
Those failures that are not displayed in the form of an error code can be easily determined by external signs.
If the boiler is switched on in heating mode, but the radiators do not heat up:
- Intake valves are blocked or not fully open. Open all the taps;
- An airlock has formed. Vent excess air from the circuit using Mayevsky taps;
- Faulty three-way valve. In dual-circuit models, the valve switches the flow of the coolant from heating to domestic hot water. If it is broken, one of the circuits may not heat up. Need diagnostics and valve repair.
Low system pressure:
- Leaking in pipes or assemblies. Check for loose joints. For insulation use a plumbing tow or sealant;
- Leakage of the membrane in the expansion tank. Replace the membrane;
- Insufficient coolant. Add fluid.
Monitor the operation of the boiler, clean the components from plaque and debris. Once a year, invite a specialist for technical inspection.
