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

A keyhole for a plastic key with a white square knob to turn: This knob will need turning like a tap to open and close. A filling loop will be built in on the bottom of your boiler on most modern and small combi boilers, but there could also be an external filling loop on the pipework.Having your Worcester boiler pressure too high(above 1.5 when the system is cold), means you will need to let some pressure (water) out of the system. Boiler pressure too high Open both of your filling valves using their handles (you may need to use a screwdriver) to allow cold water to flood your system

If the diverter valve doesn’t sound like the issue, you can read more about “Worcester boiler no hot water” in our full guide on the subject. #3 – Your Boiler Is Leaking However, if your other gas appliances are functioning well, you should call a Gas Safe engineer to inspect your boiler and determine the underlying issue. They can replace a broken thermocouple and/or remove carbon deposits from the pilot light. In either scenario, this isn’t a DIY-type job.

If the leak isn’t immediately obvious, it may be a good idea to call your boiler care company helpline or consult with a heating engineer. These professionals are trained to spot and resolve such issues promptly. Troubleshooting Leaks on a Worcester Bosch Boiler Assuming the leak isn’t affecting the latter — heat exchangers are notoriously costly to replace— the repairs should be simple enough, and the costs reasonable. You can absolutely have low pressure in your boiler system without a leak. This could be caused by bleeding radiators, a pressure relief valve problem, a vessel problem, or a filling loop problem. How to repressurise Worcester boiler To increase the pressure on your Worcester boiler you must add water to the heating system using a filling loop.

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.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? The PCB (Printed Circuit Board) is a key electrical component, which function as the boiler’s brain. Essentially, it allows all of the boiler’s electronics to communicate with each other. Since the PCB controls the boiler’s safety devices, it’s imperative that you get it looked at ASAP, so call your boiler care provider or a Gas Safe engineer without delay. Condensing boilers, like all modern ones including those made by Worcester Bosch, have a condensate pipe. This pipe vents harmful gases from your property. So, what are the reasons you may need to repressurise a boiler? There are two main causes of low boiler pressure, the first of which is that you have recently bled your radiators. This allows air to escape your system, lowering the pressure. As we wrap up, we will try to answer some of your most pressing questions about Worcester Bosch boiler pressure. What pressure should my Worcester boiler be set at?

According to Worcester Bosch themselves, the ideal boiler pressure for a system that’s off is between 1-1.5 bar.

When there is an issue or your gas boiler has stopped working, Worcester Bosch boilers display an error code Boilers are designed to control your central heating system, funnelling water throughout your home to warm your radiators and supply hot water to your taps.
