The Baxi E168 error code is a common issue that many homeowners experience with their boilers. When this error code appears, it can be frustrating and concerning, but it is important to know that there are ways to resolve the issue.
Boilers are complex systems that require proper maintenance and care to function correctly. When a fault occurs, the boiler will often display an error code to indicate the issue. The Baxi E168 error code is one such error that can occur due to a range of issues, including a power cut, low water pressure, or a faulty component.
Understanding the cause of the Baxi E168 error code is essential in determining the appropriate steps to resolve the issue. This article will provide an overview of the Baxi E168 error code, the potential causes, and the steps that homeowners can take to fix the problem.
Understanding the Baxi E168 Error Code
Causes of E168 Error
The Baxi E168 error code is a PCB lockout code that indicates a fault in the boiler’s electronic control system. The PCB (Printed Circuit Board) is the central control unit of the boiler, and it is responsible for managing and regulating various functions of the boiler.
There can be several reasons why a Baxi boiler may display the E168 error code. One of the most common causes of this error is a disruption in the electrical supply to the boiler. This can happen due to a power outage, tripped circuit breaker, or faulty wiring.
Another possible cause of the E168 error code is a gas supply fault. If the gas supply to the boiler is interrupted or blocked, the boiler may shut down and display this error code.
A faulty PCB is also a possible cause of the E168 error code. If the PCB is damaged or malfunctioning, it may cause the boiler to shut down and display this error code.
Impact on Boiler Function
When the Baxi boiler displays the E168 error code, it will shut down and stop working. This means that the boiler will not be able to provide heat or hot water until the error is resolved.
It is important to note that attempting to reset the boiler repeatedly without addressing the underlying issue can cause further damage to the boiler. Therefore, it is recommended to call a qualified engineer to diagnose and fix the problem.
In conclusion, the Baxi E168 error code is a PCB lockout code that can be caused by several factors, including electrical and gas supply faults, and faulty PCBs. When this error code is displayed, the boiler will shut down and stop working until the issue is resolved. It is important to seek professional help to diagnose and fix the problem to avoid further damage to the boiler.
Troubleshooting Steps
Initial Checks and Resets
When a Baxi boiler displays an E168 error code, the first step is to perform some initial checks and resets. The homeowner should ensure that the power supply to the boiler is not interrupted, and the boiler is not in a low-pressure state. If the power supply is not interrupted, then the homeowner should try to reset the boiler by turning it off and then on again. This can be done by switching off the power supply to the boiler for a few seconds and then switching it back on.
Assessing the Electrical Components
If the initial checks and resets do not solve the problem, then the homeowner should assess the electrical components of the boiler. The diverter valve motor and the gas valve should be checked for any faults or damage. The circuit board should also be checked for any signs of damage or corrosion. If any of these components are found to be faulty, then they should be replaced by a qualified engineer.
Evaluating the Gas Valve and Supply
If the electrical components are found to be in good condition, then the homeowner should evaluate the gas valve and supply. The gas valve should be checked to ensure that it is open and functioning correctly. The gas supply should also be checked to ensure that it is not interrupted or blocked. If the gas valve or supply is found to be faulty, then a qualified engineer should be called to repair or replace the faulty component.
It is important to note that the filling loop should not be used to increase the pressure in the boiler if the pressure is already normal. Additionally, if the pressure is low, then the filling loop should be used to increase the pressure to the normal level.
In summary, when a Baxi boiler displays an E168 error code, the homeowner should perform some initial checks and resets. If these do not solve the problem, then the electrical components and gas valve and supply should be assessed and evaluated. If any faults are found, then a qualified engineer should be called to repair or replace the faulty component.
Professional Intervention
When to Call a Qualified Engineer
If the Baxi boiler is still displaying the E168 error code after attempting the troubleshooting steps, it is time to call a qualified engineer. Attempting to repair the boiler without the necessary skills and experience can be dangerous and potentially cause further damage.
A qualified engineer will have the knowledge and experience to diagnose the issue and recommend the best course of action. They may also have access to technical support from the manufacturer to help resolve the issue.
Expected Repair Procedures
The qualified engineer will first attempt to diagnose the issue causing the E168 error code. This may involve testing various components such as the pressure switch, temperature sensors, and the PCB. If the PCB is found to be faulty, a new one may need to be installed.
The cost of the repair will depend on the extent of the damage and the cost of replacement parts. If the boiler is still under warranty, the repair may be covered. It is important to check the warranty terms and conditions before proceeding with any repairs.
If the cost of the repair is too high or the boiler is beyond repair, the engineer may recommend replacing the boiler instead. This can be a costly option, but may be necessary if the boiler is old or has suffered extensive damage.
In summary, when faced with the Baxi E168 error code, it is important to call a qualified engineer for professional intervention. They will be able to diagnose the issue and recommend the best course of action, whether it be a repair or replacement. It is important to consider the cost and warranty terms and conditions before proceeding with any repairs or replacements.
Preventive Measures and Maintenance
Routine Checks and Servicing
To prevent the occurrence of the Baxi E168 error code, routine checks and servicing of the boiler system are necessary. Regular servicing by a Gas Safe registered engineer ensures that the boiler is in good working condition and that any potential issues are identified and resolved before they become major problems.
During routine checks, the engineer will inspect the boiler system and check for any signs of wear and tear. They will also check the pressure and temperature of the system to ensure that they are within the recommended range. Additionally, the engineer will inspect the flue and ventilation to ensure that they are clear and unobstructed.
Understanding Boiler Maintenance
Understanding the basics of boiler maintenance can help homeowners prevent the occurrence of the Baxi E168 error code. One of the most important aspects of boiler maintenance is ensuring that the system is kept clean. This includes regularly cleaning the boiler’s heat exchanger, which can become clogged with debris over time.
Another important aspect of boiler maintenance is ensuring that the system is properly pressurized. Low pressure can cause the boiler to shut down, while high pressure can cause damage to the system. Homeowners should regularly check the pressure gauge and adjust the pressure as necessary.
Finally, it is important to refer to the boiler’s manual for specific maintenance instructions. The manual will provide information on how often the system should be serviced, as well as any specific maintenance tasks that need to be performed.
By following these preventive measures and performing regular maintenance, homeowners can reduce the likelihood of the Baxi E168 error code occurring and ensure that their boiler system operates efficiently and reliably.
