Why Weishaupt Burner motor does not run?
The burner motor might not be running due to several reasons: a lack of voltage, in which case you should check the voltage supply; a tripped overload relay or motor protection switch, so verify the setting; a defective motor contactor or frequency converter, suggesting a replacement; or a defective motor, which would also require replacement.
What to do if Weishaupt WM-L20/2-A R has no ignition?
If your Weishaupt Burner isn't igniting, the issue might stem from several causes. The ignition electrodes could be too far apart or short-circuiting, requiring adjustment. They might also be dirty or wet, needing cleaning and adjustment. A defective ceramic insulator or ignition cable would necessitate replacement of the respective part. Lastly, the ignition unit itself could be defective, also requiring replacement.
What to do if Weishaupt Burner has flame failure during operation?
If you experience flame failure during operation of the Weishaupt Burner, it could be due to a leaking oil supply or high suction resistance, suggesting you check the oil supply. Another cause could be a soiled or worn oil nozzle, which would need replacement. Also, check the flame signal, flame sensor and burner setting, as the flame signal might be insufficient.
What to do if Weishaupt WM-L20/2-A R combustion manager does not detect a flame signal?
If the combustion manager isn't detecting a flame signal in your Weishaupt Burner, the flame sensor might be soiled and needs cleaning. Another possibility is an insufficient flame signal, in this case you should check the flame signal, the flame sensor and the burner setting. Alternatively, the flame sensor itself may be defective, requiring replacement.
Why Weishaupt Burner safety circuit open?
The safety circuit on your Weishaupt Burner might be open because the temperature or pressure limiter on the heat exchanger has triggered. In this case, reset the temperature limiter or pressure limiter on the heat exchanger. Alternatively, the low water safety interlock on the heat exchanger might have triggered, so top up the water and then reset the low water safety interlock.
Why Weishaupt WM-L20/2-A R has poor start behaviour?
A Weishaupt Burner might exhibit poor start behavior if the mixing pressure is too high, so correct the mixing pressure in ignition load setting and adjust the mixing head if necessary. Another cause can be that the ignition electrode is set incorrectly, so set the ignition electrode correctly. Also, the fuel quantity might be too much or too little, so correct the fuel quantity in ignition position via fuel actuator.
Why Weishaupt Burner oil pump supplies no oil?
If the oil pump in your Weishaupt Burner isn't supplying oil, first check if the shut-off device is closed and open it. The oil supply might be leaking. The anti-siphon valve might not be opening, so check the valve and replace it if needed. The oil filter of the oil supply could be soiled, so clean or replace the filter insert. Lastly, the oil pump itself might be defective, requiring replacement.
What to do if Weishaupt WM-L20/2-A R fuel valve does not open?
If the fuel valve on your Weishaupt Burner isn't opening, first check the voltage supply, as there might be no voltage. Another possibility is a defective coil, which would need replacement.
Why Weishaupt Burner combustion pulsating or burner booming?
If your Weishaupt Burner is experiencing pulsating combustion or booming, it could be due to an incorrect combustion air quantity, in this case you should check combustion values. The mixing head might be set incorrectly, so set the mixing head correctly. Another cause can be back pressure from the system, so check the flue gas system.
Why Weishaupt WM-L20/2-A R Burner combustion head is contaminated with oil or has heavy carbon deposits?
If the combustion head of your Weishaupt Burner is contaminated with oil or has heavy carbon deposits, the oil nozzle might be defective, requiring replacement. Also, the mixing head might be set incorrectly, so set the mixing head correctly. An incorrect combustion air quantity can also cause this, so adjust the burner. Insufficient boiler room ventilation can be a reason, so ensure sufficient boiler room ventilation. Finally, the nozzle assembly and diffuser might not be centered, so check the centralisation of nozzle assembly to diffuser.
