Worcester Bosch Internal Filling Key To Repressurise Combi Boiler

Product Information

Thanks to these mechanisms, the likelihood of anything catastrophic happening when your Worcester’s pressure surges is quite low. You can fill in Heatable’s 90-second anonymous questionnaire to get a range of fixed-price quotes on a range of regular, system, and combi boilers from various manufacturers. Heatable also offer flexible finance options with all new boiler models. What’s Next?

Another cause could be the expansion vessel has lost its air and needs to be recharged or replaced. If your Worcester Bosch boiler is leaking — or there’s a leak elsewhere in the system — the first, and obvious step would be to locate the leak and repair the affected component. A Gas Safe engineer is best-suited to perform this task, since the leak can come from anywhere between a radiator valve to the boiler’s heat exchanger.

It might happen when your system is not heated properly, has a leak from the expansion vessel or commonly happens after removing a radiator. On rare occasions, your boiler pressure can seem low because the gauge is faulty and isn’t showing the correct pressure. In this case, you’ll need a boiler engineer to replace the pressure gauge. Why does my Worcester boiler keep losing pressure? As with other boilers, you’re aiming for a pressure of between 1 and 1.5 bars so if your boiler pressure is lower than this, you’ll need to top up the pressure. You can do this using the instructions earlier in this guide, but it’s likely you’ll need to use a filling loop as discussed in our ‘how to repressurise a Worcester boiler’ section. Other types of boiler

Do not open both filling loop valves fully straight away as the water pressure in the house might be too much for the boiler and cause the boiler pressure to shoot up too much. If you find that this light isn’t working properly — and neither is the boiler — it could be due to these root causes:

How to repressurise a Baxi boiler

Similarly, bleeding your radiators can lead to a loss of boiler pressure, so it’s important to re-pressurise your boiler afterwards. But note that repressurisation a temporary fix. To solve the problem with your Worcester Bosch, and clear any error codes, you’ll need to find the leak and fix it before you top up the system. When installed by a Worcester Bosch Accredited Installer with a Greenstar System Filter. The Greenstar 1000 and Greenstar 2000 guarantee is available as standard to both Excelerate members and non-WAI's, when fitted with any brand of system filter. Terms and conditions apply. The most likely reason you’re seeing a pressure increase is that the system has too much water in it. If you have a keyless filling loop, there should be a blue lever at the bottom of the unit. All you have to do is pull that lever down to repressurise the system. When the pressure is more than one bar, you can release the lever. Boiler is Leaking – Worcester Boiler no hot Water

You can do this via a drain-off valve. A drain-off valve can be on the boiler, a radiator valve or anywhere on the central heating pipework. Low boiler pressure can be fixed easily by topping the pressure up, if you have to keep topping the boiler pressure up, you have a problem that needs to be fixed. Worcester Boiler Keeps Losing Pressure As a Worcester boiler comes alive and its heat exchanger begins to heat water, the pressure rises. That’s because hot water expands in volume at an accelerating rate as the temperature increases. The codes above point to a leak in the system, which is the most common cause of any boiler losing pressure. When the Pressure Rises Too MuchHere 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. The boiler pressure should rise by about 0.3-0.5 bar when the boiler starts heating water, but should never rise above 2.75 or fall below 0.5 bar. How do I increase the pressure on my Worcester boiler? Worcester Bosch boilers are pretty perfect. But, like most boilers (and humans, for that matter), they’re prone to various maladies brought on by pressure that’s too high or low. That’s why in this post, we will walk you through all things related to Worcester boiler pressure. Like with low pressure, there can be several reasons for a boiler’s pressure rising above normal operational levels.
