Worcester Bosch Internal Filling Key To Repressurise Combi Boiler

Product Information

Once the leak is gone, the next step involves re-pressurising the boiler. Different boilers have different ways of getting re-pressurised. We’ll walk you through these methods below. Filling Link

If the boiler pressure drops, it means the water is getting out which should not be happening. Worcester boiler low pressure Unfortunately, some idiot at Worcester Bosch thought it would be a good idea to use a key to repressurise their boilers. Here are the steps to repressurise the Worcester combi boiler using an internal filling key. If you are seeing a Worcester bosch error code that means low pressure in the boiler, then this will sort that out.

This can cause the pressure gauge to move around so you don’t get an accurate reading but it isn’t a big deal. How do I increase the pressure on my Worcester boiler? For most Worcester boilers, problems should be few and far in between. Something breaking isn’t necessarily a representative example of the brand’s overall quality — but it can still happen.

Before you can change the pressure on your boiler, you need to identify what kind of filling system you are using.

Various boiler issues are indicated by alphanumeric error codes, all which start with “EA” and conclude with a series of numbers.

Thanks to these mechanisms, the likelihood of anything catastrophic happening when your Worcester’s pressure surges is quite low.However, while operating the combi boiler, if you notice that the pressure gauge or indicator has dropped down to the red zone, then you must repressurise it immediately. To find out which it is, you can tie a carrier bag to the end of the copper blow-off (overflow) pipe outside. Boiler blow-off pipe This is most likely an expansion vessel problem, if so, you will need to recharge the expansion vessel, or you’ll have to replace it if the diaphragm inside is split. To increase the pressure on your Worcester boiler you must add water to the heating system using a filling loop.
