The CE error on your Bosch gas boiler can indicate various issues. To resolve it, check for problems such as faulty wiring, sensor issues, or ventilation blockages.
Wiring Issues Inspect wiring connections for any loose or damaged wires.
Sensor Problems Ensure sensors are clean and properly connected. Replace any malfunctioning sensors.
Ventilation Blockages Clear any obstructions in the ventilation system to allow proper airflow.

CE error

Any user of German Bosch equipment may eventually experience operational issues. This company is rightfully regarded as a pioneer in the manufacturing of heating system components and equipment. Any technique can frequently experience a brief malfunction due to a variety of factors. Electronic devices are no different. Typically, every boiler manufacturer outfits their electronic "stuffing" with a variety of control sensors. This is carried out to make it easier for heating equipment to operate during use.

Because of the way the Bosch boiler device is constructed, any error that occurs during operation will be shown as an alphanumeric or numeric value on the indicator panel. We will comprehend the error pertaining to the letter value CE today. This kind of error (CE indication) indicates that the heating system’s water pressure has decreased. The pressure gauge installed in the lower corner of the boiler’s right side provides additional evidence of low water pressure.

It is essential to focus on the pressure gauge pointer’s arrow. The following adjustments are required if the pressure is less than 0.5 bar and it is in the lower red zone:

  1. Open the make-up tap (feed the boiler with heating medium).
  2. Remove the blue knob from the lock at the bottom of the boiler (pull it down like a flag).
  3. By turning the blue flag counterclockwise scroll until the pressure in the boiler rises to 1.5 bar. This will be indicated by pressure gauge readings.
  4. Next, close the make-up tap, and return the flag to its original position.

It is essential to disassemble the boiler and inspect the water pressure sensor if this process is ineffective and the CE error continues to flash.

Disassembly of the boiler

The following actions are the first in the boiler disassembly process. This is required to ensure the safe disassembly of certain components and to remove the chance of unintentional electronic damage during a short circuit while inspecting electronic components. It is imperative that the following tasks be completed:

  • turn off the boiler on the control unit;
  • Remove the power plug from the socket;
  • Close the gas supply tap;

Further disassembly can start after the initial safety measures. Unfolding the control panel is the first step. For this, a Phillips screwdriver is needed. The boiler has two fastening bolts located at its base. Using a screwdriver, they must be unscrewed and taken out of the thread groove. Remember that installation is done in reverse order and that all threads must be unscrewed counterclockwise.

Once the bolts have been undone and taken out of the grooves, smoothly lower the panel and rotate it in your direction by moving the top portion downward. You can see different boiler assemblies and control units inside. On the left side is where the water pressure sensor is situated. Two cables, one blue and one black, are approaching it with connectors. Typically, the sensor has a housing made of black plastic.

As soon as possible, check the sensor’s contacts at 1.5 bar of water pressure in the system. To accomplish this, unplug the sensor’s connectors, switch on the multimeter, and select the mode for examining the electrical circuit. To examine the electrical circuit on the sensor contacts, use feeler gauges. The sensor is out of order if it indicates that the contacts are open (no changes appear on the multimeter screen).

To put it in perspective, the pressure sensor itself is a type of controller that serves as a controlling device. In other words, the coolant (water) enters the sensor itself at the predetermined system pressure, which in this case is 1.5 bar, applying a specific pressure to it. The boiler control unit receives a command indicating that everything is normal (the CE indicator is not lit) and the internal circuit is closed.

We’ll examine the CE error in this post, a problem that many owners of Bosch gas boilers encounter. Although this error can be annoying, you can save time and trouble by knowing why it occurs and how to fix it. We’ll examine the possible reasons for the CE error and offer helpful solutions to troubleshoot and fix it, whether it’s an ignition, gas supply, or other issue. You can resolve this problem and maintain the efficiency of your Bosch gas boiler, keeping your house toasty and cozy all year long, with clear instructions and guidance.

Removing the pressure sensor

Closing the heating system taps is required in order to replace the failed sensor. Attach the drain cock socket. The boiler’s drain cock, which resembles a black pipe, is found at the bottom. To empty the boiler’s water, unscrew the socket with the tube on it in a clockwise direction. The boiler’s water pressure will be returned to its lowest possible level in this manner. Close the drain cock once the boiler’s pressure gauge arrow has reached the zero position.

Following these procedures, the water pressure sensor within the system can be disassembled. The following procedures are used to disassemble this device:

  • take the sensor in your hand, carefully unscrew it to the left;
  • With the help of a screwdriver, remove, by moving the screwdriver blade, the bracket upwards;
  • remove the sensor by pulling it towards you;

A new pressure sensor is available at the Pyramid 24 retail chain. Every item is premium and comes from reliable vendors with the necessary certifications. Only manufacturer direct deliveries, and most importantly, all parts and components are always reasonably priced.

Error codes can be annoying if you own a gas boiler, such as the Bosch type. The CE error is one of the frequent mistakes you may run into. Your heating system may be interfered with by this error, leaving you without heat. But worry not—you can save time, money, and discomfort by learning why it happens and how to fix it.

Your Bosch gas boiler’s CE error usually points to an issue with the electronics or component communication. It could be caused by problems like bad wiring, broken sensors, or a power supply interruption. While seeing this error code can make you want to freak out, the key to solving the issue is to remain composed and carefully troubleshoot the issue.

There are a few things you can try to fix the CE error on your own before contacting a professional. First, turn the boiler back on and off to reset it. This easy step can occasionally fix the issue and return the system to normal. Examine the wiring for any evident damage or loose connections, and take appropriate action if needed. Make sure the boiler’s ventilation is clear and that the gas supply is continuous.

It’s time to move on to more in-depth troubleshooting if the CE error is not resolved by resetting the boiler and looking for obvious problems. For detailed instructions on interpreting error codes and carrying out advanced diagnostics, consult the handbook that came with your Bosch boiler. You could try doing your own inspection and replacement of malfunctioning sensors or parts, depending on your comfort and skill level. It’s advisable to seek the assistance of a trained technician if you feel uneasy or uncertain about performing this task.

Avoid being left in the dark about your Bosch gas boiler’s CE error. You can fully restore the functionality of your heating system by comprehending its potential causes and employing a methodical troubleshooting and repair approach. Your home will remain warm and cozy even during the coldest months if you solve the CE error as soon as possible, whether you choose to do it yourself or hire a professional.
