Worcester Bosch Internal Filling Key To Repressurise Combi Boiler

Product Information

Now, keep in mind that these units will slowly lose pressure over time. However, if it happens all of a sudden, then you are having a problem. 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 With most Worcester Bosch boiler models, resetting the boiler is as easy as pressing and holding the reset button for about 3-5 seconds. The button is typically located on the boiler control panel. Worcester boiler flashing red light: a red light means that your unit has to be inspected by a professional boiler engineer. Keep in mind that your warranty will be valid provided that you keep up with your annual maintenance after installation. Not providing the yearly service might dissolve the warranty.

Ideally, the gauge should read between 1 and 1.5. But if it reads less than 1 bar, your boiler pressure is too low and needs re-pressurising.

Common Worcester Boiler Error Codes

The pressure will begin to rise. Wait until it reaches one bar. Now, turn off the two taps. Remove the hose. Getting the best combi boiler for a large houseis very important, but adding an external expansion vessel that is large enough for the central heating system is also an option rather than upgrading to a bigger boiler. External expansion vessel fitted Thanks to these mechanisms, the likelihood of anything catastrophic happening when your Worcester’s pressure surges is quite low. Worcester boilers are sometimes undersized when fitted and are not large enough to cope with a large house’s central heating system.

You’ll have to find out why the boiler pressure is low in the first place. In most cases, it’s because of a leaky central heating component, so you’ll have to locate the leak and repair it before topping up the boiler. A leak that’s causing boiler pressure loss needn’t be in the boiler itself. Whilst it can affect many of the boiler’s internal components, a leak may just as well occur anywhere else in the heating system, including radiators, valves, pipework, and towel rails. When the boiler is offline and the pressure gauge shows a reading of 0.5 bar or lower (which is in the red zone on the dial), the pressure is too low. 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.

High Worcester Boiler Pressure Causes and How to Fix

Leaks can be anywhere on the full central heating system, boiler, radiators, or pipework under floors. Worcester Boiler Leaking Water You can use our guide to diagnose a faulty diverter valve here; it’s typically the problem when the central heating system works but there’s no hot water in your taps. High pressure can damage your boiler in a variety of ways, including leaks in the system and a build-up that can eventually cause permanent damage. If you notice that your hot water isn’t as warm as it should be, it’s possible that your low boiler pressure is affecting the temperature of your hot water.
