An error such as the EA code on your Bosch Gaz 6000 can be annoying if you depend on your gas boiler to heat and cool your house in the winter. But have no fear—you can troubleshoot the problem and restore the functionality of your heating system by knowing the probable causes and remedies.
Many homeowners choose the Bosch Gaz 6000 gas boiler because of its dependability and effectiveness in heating homes. It may, however, occasionally experience malfunctions, just like any other appliance. The EA code is one error that denotes a problem with the combustion process of the boiler.
Your Bosch Gaz 6000 gas boiler may experience the EA error for a number of reasons. A common cause of the error code is a shortage of oxygen reaching the combustion chamber, which can interfere with the gas’s ability to burn. This might be the result of inadequate airflow surrounding the boiler or blocked vents.
An additional potential reason for the EA error could be an issue with the ignition system. As a safety measure, the boiler may display the EA code if the gas cannot be ignited properly. Problems with the ignition system may result from malfunctioning parts or a debris accumulation near the burner.
Thankfully, there are actions you can take to diagnose and fix your Bosch Gaz 6000 gas boiler’s EA error. To begin, make sure there are no obstacles in the way of the air vents by inspecting them. To enhance the flow of air into the combustion chamber, clean the vents if required.
Next, look for any evidence of debris or damage in the ignition system. If it’s safe for you to do so, you can clean the burner and ignition parts thoroughly to get rid of any buildup that might be preventing the ignition from happening.
It might be best to get in touch with a licensed heating technician to identify and fix the issue if these steps are ineffective. Their proficiency and equipment will enable them to locate the source of the EA error and guarantee that your Bosch Gaz 6000 gas boiler is operating safely and effectively once more.

Boiler overview
Low-cost, two-circuit turbo variant. It is a miniature boiler room with all the parts assembled in one small, practical location. The boiler’s principal parts are:
- circulation pump;
- gas valve;
- plate heat exchanger;
- air relief valve;
- emergency valve;
- combustion chamber;
- primary heat exchanger;
- turbine;
- differential valve;
- sensors;
- flat expansion tank.
The control panel is used to keep an eye on the control. Experts advise getting an additional voltage stabilizer before installing the boiler. It must be protected from power surges by doing this. Installing lightning protection is just as important, particularly if doing so requires installing a boiler in a rural home. These installations are frequently seen on the rooftops of apartment buildings.
What does the error EA?
A comprehensive diagnosis must be performed if the Bosch boiler does not have ignition and the corresponding message, error EA, shows up on the screen. There could be a number of reasons for this. Three basic steps are the first of any work:
- Switching off the boiler with the corresponding button.
- Unplugging the power supply from the socket.
- Close the gas supply tap.
Crucial! You can move on to the diagnosis process only after these three requirements have been satisfied.
Take off the decorative cover and unfold the control panel. To disassemble the boiler, take out a Phillips screwdriver and loosen the two screws on the bottom. The panel must then be turned toward you and angled slightly downward.
Next, two self-tapping screws will need to be undone in order to remove the upper decorative cover. Remove the cover from the fastener by lifting the bottom. The boiler furnace is the final barrier in front of the ignition electrodes. In order to accomplish this, loosen the five screws, pull the cover in your direction, and drop it slightly.
The output of a boiler can range from 18 to 35 KW. It has a gas burner fitted to it. The burner on the right has a single ignition electrode installed, while the burner on the left has a flame control electrode.
In this article, we delve into the common issue of the EA error on Bosch Gaz 6000 gas boilers, focusing on its causes and solutions. When your boiler displays the EA error, it can be frustrating and disruptive to your home"s heating system. Understanding why this error occurs is crucial for timely and effective resolution. From issues with the gas supply to problems with the ignition system or even sensor malfunctions, various factors can trigger the EA error. However, fear not, as we"ll guide you through the troubleshooting process and offer practical tips for eliminating the error and restoring your boiler to optimal functionality. Whether it"s a simple reset, checking for gas leaks, or consulting a professional technician, we"ll help you navigate through the steps to ensure your home stays warm and cozy.
Checking for spark
Verify if the spark plug on the left side is producing a spark.
First things first, the absence of ignition spark needs to be crossed off the list of issues. The following is the action algorithm:
- Connect the power supply.
- Press the "Reset" button for 3 seconds to restart the boiler.
- If the spark has steadily started hitting the gas ramp, then the problem is not with the electrode.
- Switch off the boiler.
It is now required to move forward with the diagnosis of the next potential Bosch boiler EA error issue.
Gas valve
It must be made clear if gas enters the gas valve and if the shutter opens in response to a boiler ignite. It is advisable to remove the boiler’s left side cover in advance to facilitate the diagnostic process. In total, eight screws hold it in place. Take off the clips that secure the panel. There are screws on the front, back, inside, and outside. Take out the panel’s rubber seal. Slide the panel out of the way and in your direction.
The middle, blue-colored gas valve is where you’ll find it. It is precisely the same, but rotated 90 degrees, in Bosch boilers.
The gas valve on this Bosch boiler type is almost 90 degrees out of angle. This means that the inlet gas pressure test probe will be situated on the valve’s back side. What you must do in order to diagnose is as follows:
- Using a Phillips screwdriver, unscrew the sampler screw on the gas supply inlet of the gas valve. Literally a couple of turns are enough.
- Turn on the micromanometer. Connect the silicone pipe to the gas valve to check the pressure of the incoming gas.
- Open the gas supply tap.
- If the device shows about 230-240 mm of water. st., this is considered to be within the normal range.
- Close the gas supply tap.
- Disconnect the branch pipe.
- Screw back the screw of the sampling device.
The gas outlet valve now needs to be adjusted in the same way. It is required to connect the boiler to the power supply and open the gas supply tap after plugging in the micromanometer socket. The fan should activate after the boiler is turned on, and then the ignition should function. The source of the Bosch gas boiler error EA is found if the micromanometer indicates that there is no gas pressure at the outlet.
The Bosch boiler’s interior
It can be inconvenient to encounter an EA error on your Bosch Gaz 6000 gas boiler, particularly if it leaves you stranded. But do not worry; you can restore the functionality of your heating system by learning the potential causes and how to troubleshoot them.
A common cause of the EA error is an inadequate supply of gas. This might be the result of a problem with the gas meter, a break in the gas line, or even problems with the gas valve. The problem can be solved by inspecting these parts to make sure there are no leaks or obstructions.
Insufficient air supply is another possible cause of the EA error. The error code may appear if the boiler is not getting enough air to burn. This problem can be resolved by checking air vents, flues, and making sure there is enough ventilation surrounding the boiler.
Moreover, issues pertaining to the ignition system may also give rise to the EA error. The boiler may not fire up properly due to problems with the ignition control module, ignition electrodes, or cables. Such problems can be avoided by giving these components regular upkeep and cleaning.
In rare circumstances, the EA error can also point to a more serious boiler issue, like a broken sensor or control board. It is advisable to seek professional assistance from a qualified technician to diagnose and repair the issue if basic troubleshooting steps fail to resolve it.
To sum up, while an EA error on your Bosch Gaz 6000 gas boiler can be annoying, it’s not always a reason to panic. You can successfully address the problem and guarantee that your heating system keeps running smoothly and efficiently by comprehending the possible causes of the error and implementing the necessary troubleshooting procedures.
