This blog discusses the possible causes of Worcester Bosch boiler error code 1017 W and how to repair your boiler.

Worcester Bosch Boiler 1017 W Error Code

Error code 1017 W on a Worcester Bosch boiler is an indication of low water pressure. This error code is typically accompanied by a flashing red light on the control panel, signalling that the water pressure has fallen below the recommended level.

If you own a Worcester Bosch Greenstar 8000 boiler, you may have experienced the frustration of receiving a low water pressure error code. This error code is triggered by a pressure sensor that is constantly monitoring the water pressure in your Worcester boiler. A significant pressure drop can indicate a problem that needs to be addressed.

It's important to note that the water pressure in your Worcester Bosch boiler should always be between 1 and 1.5 bar. If you encounter this error code, it's important to identify the cause as quickly as possible. This may involve checking the boiler's heating control, flow, gas, heat, and flame, as these elements can all impact water pressure. A professional gas-safe engineer must reset or replace the pressure sensor. While this may be daunting, it's important to tackle the issue head-on to ensure your boiler runs efficiently and safely.

Common Causes For 1017 Error Code in Worcester Boilers

Water leaks
As a professional boiler service company, one of the important tasks that should be included in your routine maintenance is checking for any signs of water leaks around the boiler or within the heating system. If left unaddressed or unreported, leaks can lead to a loss of pressure, causing a chain reaction of issues with the control code, flame, gas flow, and even the sensors.

Don't rely on the heating system to reset itself; a regular boiler check or annual boiler service is needed to prevent faults and errors. So, if you spot any visible signs of water leaks, take swift action and do not procrastinate.

Closed valves
One crucial step in maintaining your boiler is ensuring all valves leading to and from it are fully open. Closed valves restrict water flow, resulting in a pressure drop. This can cause serious issues like a fault code or flame error, which can be expensive and time-consuming to fix.

To avoid these problems, regular boiler checks are essential. Remember, a properly functioning boiler will keep your home warm while saving you money on heating bills. Don't hesitate to call a professional gas-safe engineer if you need assistance with a boiler reset or sensor control issues. By doing a quick check of your valves, you can keep your system operating smoothly and effectively.

Filling loop
The filling loop is a device used to increase the water pressure in the heating system. If you find that the pressure has dropped, then the filling loop can quickly rectify the issue. However, ensuring the filling loop is connected correctly, and the valve fully opens is crucial to increase the pressure. If you're unsure about this process in your Worcester boiler, consult the boiler's user manual or contact a licensed heating professional to do this task.

Remember, regular boiler check-ups can help to identify any faults or errors, and you should never attempt to reset any codes or control the flame without having the necessary knowledge and experience. It's also essential to regularly check the gas flow, heat, and sensors to safeguard against any potential issues.

Faulty pressure relief valve
As a professional technician, it's important to note that a faulty pressure relief valve can cause a cascade of issues in your boiler. This valve is designed to release excess pressure from the system. If it malfunctions, it can result in low water pressure and shows a fault or error in the control code.

It's crucial to regularly check the system, boiler, flame, gas flow, heat sensor, and any other key components to identify any potential issues before they become more serious. If a faulty valve is detected, it must be replaced promptly to ensure the system is operating efficiently and safely. A reset may temporarily solve the issue, but a long-term solution is always preferred for the longevity of the Worcester boiler. However, a professional technician should inspect and replace the valve if necessary.

System blockages
When it comes to your heating system, a blockage within the pipes or heat exchanger can be a major cause of frustration. This accumulation of debris or sludge can severely restrict water flow and ultimately lead to low pressure. However, power flushing the boiler system can resolve this issue quickly and efficiently. It's essential to watch for error codes or faults, as these can point to a potential blockage.

A boiler check by a professional heating engineer gives you peace of mind knowing everything is running smoothly and that the heating works to its full potential. Whether you need to replace a sensor or simply require some maintenance, don't ignore the signs of a potential blockage and ensure your Worcester boiler runs safely and efficiently.

However, once you have identified the possible cause of the low water pressure, then steps can be taken to rectify it.

Troubleshooting a Worcester Bosch Error Code 1017 W

Check for leaks
As a professional, it is crucial to always check for leaks when inspecting a heating system. Not only can leaks result in costly water damage, but they can also cause a decrease in efficiency, increase the risk of a health hazard, and lead to system breakdowns. When examining the boiler, pipes, and radiators for any visible signs of leaks, make sure to follow applicable codes and guidelines to ensure the boiler is functioning safely and efficiently. If a leak is detected, contacting a qualified heating engineer is important to address the problem promptly.

Open valves
To ensure the smooth functioning of your Worcester boiler, it is crucial for all valves leading to and from the boiler to be fully open. This is one of the fundamental codes to keep in mind while dealing with boilers. Any isolating valves, filling loop valves, or any other valves within the system must be checked and opened as necessary.

Failing to open these valves can result in heating issues, faulty sensors, flame control errors and many other system faults. Therefore, all valves must be double-checked and kept open to avoid such problems and guarantee the boiler's safe, controlled, and proper functioning.

Re-pressurise the system
If you face low water pressure in your boiler system, don't worry. You may be able to re-pressurise the system yourself with just a few minutes of your time. Simply refer to your boiler user manual for specific instructions on how to do this. Normally, the filling loop will increase the pressure to the recommended level. If you ever encounter a problem that requires you to reset the boiler, you may need to consult a professional to ensure that all sensors and temperature controls are properly calibrated.

Bleed radiators
If you undergo low water pressure in your home, air trapped within your radiators may be to blame. Bleeding the radiators is a simple process that can release the trapped air and restore the water flow. To begin, start from the lowest radiator in your property and
work your way up, one by one, until water is flowing freely and is free of bubbles. It's important to ensure that your radiators are working efficiently and safely, and keeping them free of any fault or error is essential.

Therefore, if you notice any flame, gas flow, or temperature control issues, consult a professional boiler engineer and make any necessary adjustments or resets. By properly caring for your radiators, you can ensure optimal heat and comfort in your home.
