Sime Boiler Error 06

What does this fault affecting the Sime boiler mean?

You well know that boilers are devices that provide us with comfort and well-being in our home, especially during the winter when it’s colder and you need hot water for everything you need. However, like any device with electronic components, boilers can present some faults that affect their normal operation.

The error code 06 fault in Sime boilers indicates that the boiler does not detect the flame after ignition. This can be due to various causes that we will discuss below, and which may have simple solutions or require the intervention of a qualified professional.

These are the possible causes that can lead to this fault in your Sime boiler:

• The ignition electrode is dirty or damaged: The electrode is responsible for generating the spark that ignites the gas. If it doesn’t work properly, the boiler will fail to ignite and will display an error on the screen.
• The flame is unstable or insufficient: The flame should be blue and steady to ensure good combustion in the boiler. If it is yellow or orange, or if it goes out easily, it may indicate a problem with the gas-air mixture or gas pressure.
• The air and/or exhaust ducts may be blocked: The ducts are responsible for supplying the air necessary for combustion and expelling the resulting gases. If they are blocked by dirt, dust, cobwebs, or other objects, they can hinder the proper functioning of the boiler.
• The gas supply is insufficient or nonexistent: If there isn’t enough gas reaching the boiler or if there’s an interruption in the supply, the boiler will not be able to ignite properly or maintain the flame.
• A problem with the internal wiring of the boiler: It may happen that heat or excessive use has melted some of the wires, or that a rodent has chewed or bitten part of the wiring, and now you’ll need to check everything.

All these causes can lead to this fault in your Sime boiler, but to solve it, we will apply a series of solutions that we will explain later.

How can the error code 06 of the Sime boiler be fixed?

Today, we have prepared for you a list of possible solutions to this fault affecting Sime boilers. You just need to follow all the steps to the letter and not skip any of them:

1. Turn off and disconnect the boiler from the electrical outlet to reset it: This can help reset the sensors and the overall system of the boiler to eliminate potential temporary errors. To do this, you simply need to turn off your Sime boiler and disconnect it from the power outlet. Wait a few minutes (between 10 and 15) and then reconnect your boiler. Now turn it on and check if the fault still appears on the screen. If the problem persists, continue with the following steps.
2. Check that the gas supply is activated in your home: Verify that your gas supply is activated and functioning properly. If necessary, turn on another appliance that also uses the gas supply and check if it works well. If you have a gas supply interruption, contact the supplying company to ensure that your service is activated and working.
3. Clean the ignition electrode of your boiler and replace it with a new one if necessary: You need to check the electrode that produces the flame in your boiler. To access the electrode, you have to open the front panel of the boiler and locate it near the burner. Be careful when handling it and always disconnect the boiler from the electrical outlet before handling such components. If the electrode looks very dirty, you can clean it with a dry cloth or a soft-bristled brush. You can use some electronic cleaner to help with this task. Ensure that the electrode is properly calibrated and leveled and that it is well connected to the boiler. If you notice that the electrode is not working properly and/or does not generate the appropriate spark, then replace it with a new one that is compatible with your Sime boiler model.
4. Clean the air and/or exhaust ducts, both the intake and the exhaust ones: To clean the ducts, you need to disconnect the boiler for safety and remove the tubes that connect them. Then, use a vacuum and/or compressed air blower to remove the dust and residues that may have accumulated. You can also blow through the tubes to clear them, although we advise using a blower as soot can harm you if inhaled. It is common for birds and/or rodents to nest in the exhaust vent, so you need to thoroughly inspect and clean this vent. Once you have cleaned everything well, reconnect these ducts to your boiler and check if the fault persists.
5. Check the internal wiring of your Sime boiler: If you haven't used the boiler for a long time, rodents may have chewed on some of the wires and disconnected them. Check if the boiler's wiring is chewed, loose, or burned. It is also possible that the wiring has melted from the heat or has become corroded due to the boiler's moisture. Remember that a boiler is designed to operate at high temperatures, but over time the insulation protecting the wiring can deteriorate until it melts from the heat, affecting the device's operation. Replace any damaged wires and check if the fault has disappeared.
6. If the problem persists, please review all the steps mentioned above: It is important to check all the steps and solutions described before calling Sime technical support. Make sure you have carried out all the checks and repairs within your reach before seeking professional help and spending money that may not be necessary. We are saving you money because we care about your pocket! So please do a second check of everything we've indicated, and if the problem persists, it might be best to leave the matter in the hands of experts.
7.
