About this deal

It’s the air pressure switch that monitors air pressure in the boiler and determines if it’s safe for the boiler to start and continue operating. When this air switch malfunctions, your boiler may not get the all-clear to start working. The Fix There are a few other things that may have gone wrong to mean you have to endure a cold shower. Do you have a faulty diverter valve?

However, there’s no point engaging in pricey boiler fan motor repair if the unit is already old — the “bandaid” fix won’t last long, and you’ll likely need a whole new unit anyway. The Fix First, you need to find a Gas Safe heating engineer or call the provider of your boiler cover to find and fix the leak. Issue with the flame signal after closing the fuel supply. The air/gas ratio control valve might need replacing.That said, there’s an array of other faults that may be responsible for a noisy boiler, so it’s always best to get a qualified professional to investigate the problem.

This means that there is an issue with the Tank negative thermistor coefficient (NTC) and may be defective. The burner control unit that has been fitted is not compatible with the KIM (boiler identification module).assured conform to the safety and performance specification that the boiler manufacturer recommends. This signifies there is a flame signal without a flame present. The air/gas ratio control valve may need replacing. You can attempt to power flush your boiler and fix this error, however it is usually a sign of needing a replacement heat exchanger. Consistent kettling problems will usually only occur in boilers that have been installed for a significant number of years. Consider replacing your boiler for a new Worcester Bosch model which comes with a 10 year warranty as standard. Enjoy peace of mind for the next decade, and save more money in the long run - rather than replacing old parts of an inefficient boiler. Boiler problem 5: no power to boiler Worcester Bosch boiler spares has everything you need to service, repair and install Worcester Boilers. This means there is no signal from the flow temperature sensor available – connect the plug to the flow temperature sensor correctly or the temperature sensor could need replacing.

Instead of wasting money on boiler fan motor repair, we’d suggest having a Gas Safe engineer replace the boiler’s fan altogether.Your central heating pump may be the culprit when it comes to locating a leak and fixing a sudden drop in boiler pressure. The valve seal on a pump will wear down over time naturally, especially if too much pressure is placed on it or there is a sudden increase in water flow. When it comes to the issue of pressure within your boiler, the problem can be simple and easy to solve, or a lot more serious.

Worcester boiler faults tend to occur very rarely due to the quality and reputability of their components. As your boiler starts to get older and issues do start to show, you can use Worcester boiler error codes to diagnose the issue. It is important to keep in mind that the process of actually fixing any issues should be left to an engineer to be on the safe side. There may also be damage to the electrode or Ignition lead, without these parts a flame can’t be made. Depending on your boiler brand, you’ll see different fault codes indicating problems with the boiler fan. Here’s a list of fault codes showing fan issues from various manufacturers:Sorry to bump up an old thread, but I've just had my fan on a 28i replaced by a service engineer at age 26 months. The new fan is working fine, but we got to chatting about the way repairs always involve swapping complete components and whether the fan PCB alone could be replaced. The engineer said he would be interested to know whether the circuit had failed due to moisture within the older enclosed plastic shell on this version, and I said that I'd take a look at the old board based on my (limited) hobbyist electronics knowledge (and perhaps with the help of my friend who services consumer electronics products for a living). The problem is it would be nice to know the values on the terminals of the plug and any other information relevant to testing the fan unit. The responses on the thread seem to be rather unhelpful. I shan't be putting the fan anywhere near the boiler as I am a firm believer in letting the experts handle gas appliances, but I wouldn't mind having a spare fan if the fault just turns out to be a PCB capacitor or similar. Can anybody describe the normal service test procedure (with fan disconnected from the boiler)? Fingers crossed, this is a fan speed issue, not a faulty boiler fan. If this is the case, a Gas Safe engineer will be able to adjust the fan speed and reset the boiler. #2 – Loose Wiring/Connections Firstly, a boiler fan doesn’t cool the components inside a boiler — it’s there to drive flue gases out of your home.
