content: HI, could not find any specific reference online to this issue so far.My WESD51 powers up just fine showing on screen the last used temperature, I can also dial the knob and go up and down, but past a couple of seconds, it always goes to show always 483. Iron stays cold. Even when disconnecting the iron (PES51) same error I get the same behaviour. It started doing so when I changed the temperature from my usual ~200 C range for leaded and went up to 330 or thereabout.Update:Chatgpt gave me a clue which I did not know and the error seems to be related to the heating element.. wish I had a spare to test it with.Error code 483 on a Weller WESD51 soldering station typically indicates an issue with the heating element or temperature sensor within the soldering iron itself. This error usually means that the station is detecting an open or short circuit in the iron.Here are a few potential causes and troubleshooting steps you can take:1. **Faulty Heating Element:** The heating element inside the soldering iron might be damaged or broken. Check the connections between the element and the iron's tip. If you have access to a multimeter, you can test the continuity of the heating element to see if it's intact.2. **Loose Connections:** Ensure all connections between the soldering iron, the station, and the power outlet are secure and free of any corrosion or damage.3. **Temperature Sensor Malfunction:** The temperature sensor inside the iron could be malfunctioning, causing the station to detect an error. Unfortunately, diagnosing and fixing this issue might require professional assistance or replacement parts.4. **Overheating Protection:** Some soldering stations have built-in protection mechanisms to prevent overheating. If the iron overheats, it may shut down and display an error code. Allow the iron to cool down completely before attempting to use it again.5. **Station Malfunction:** In rare cases, the issue might be with the soldering station itself rather than the iron. Try using a different iron (if available) with the station to see if the error persists. If the problem persists with other irons, it's likely an issue with the station itself.The Weller WESD51 soldering station typically displays various error codes to indicate specific issues. While the exact list of error codes may vary slightly depending on the manufacturer and model, here are some common error codes that users may encounter with the WESD51 model:ERROR 001: This code often indicates a general fault or malfunction in the soldering station. It could be due to various reasons such as a power supply issue, internal circuitry problem, or component failure.ERROR 483: As mentioned earlier, this error typically indicates an issue with the heating element or temperature sensor within the soldering iron itself. It may suggest a problem with the continuity of the heating element or a malfunctioning temperature sensor.ERROR 888: This code may appear when there's a communication error between the soldering station and the soldering iron. It could be due to a loose connection, damaged cable, or malfunctioning communication components.ERROR 999: This code generally indicates a severe malfunction or internal failure in the soldering station. It may require professional servicing or replacement of components.Funny thing I could not find any of these codes published in the original manual.
