WORCESTER BOSCH BURNER SEAL Technical Bulletin TB138 Leaking Burner Seal. Boiler Service Worcester Bosch boiler service and TB01328. So, that's a technical bulletin from Worcester and that's talking about the burner seals on the top of the boiler. My name is Allen Hart, and in today's video I'm just going to go through this technical bulletin from Worcester. Also, go through a few tips on servicing a Worcester Bosch boiler. As always, if you can add a comment below, like, share, all that good stuff, I really appreciate it. Before you start, before you work on any boiler, if you're a new trainee especially, make sure that you read the installation and servicing instructions for whichever boiler that you're going to work on. Also, if there's any up to date technical bulletins from Gas Safe or from the boiler manufacturers. Just to bear in mind that these instructions sometimes could be out of date. If this boiler is 8, 9, 10 years old, it may be they've found that there's a problem with that boiler, or there's extra guidance for that boiler, and it wouldn't be in the original installation instructions. So, just a tip for you there. So, what we'll do, I'm not going to go through everything with this boiler, but I'm going to go through as many bits and bats as I can. So, first of all, when you're going to work on a boiler, obviously you do your safety checks on the boiler. You'd isolate the boiler, you'd check your fuse spur, make sure you've got a three amp fuse in there if that's what the boiler requires. Some other boilers, warm air for instance, it might need a five amp fuse, but again you'd check with that particular boiler. On this boiler, all we've got, we've got two screws on the top, one on this side and one on this side. So, we'd remove them two screws, and then at the bottom we've got two screws, one on one side and one on the other. They're slightly slanted. The bottom ones sometimes can be a little bit awkward when you put them back together, but we'll have a look at the case and I'll show you why on that once we've took it off. So, I've removed the screws already on this, so we're just going to take the case off, and that just comes off. It is a little bit awkward sometimes, but it's not too bad. I'd just to thank Worcester as well for doing these technical bulletins because it's really, really helpful. Not all manufacturers do it, some manufacturers, they just make the boilers. If there's problems in the future, you don't really get to know about it, but Worcester help the engineers with that. So, we can thank Worcester for that. And before we do anything inside this boiler, I'd normally be looking inside, check to see if there's any leaks. See if that's been leaking. See if there's any stains at back of the case, because sometimes flues can leak, on all boilers really for this, flues can leak, and it can drip down the back, and on some of Worcester's this gas valve will lower down and it can short the gas valve. We replaced the boiler once and they'd had engineers out a few different times. Luckily, I only went to replace the boiler, I didn't actually go to do the repair. But if I'm honest with you, I probably wouldn't have known, at that time I wouldn't have known about that fault. So, what had happened is water had been leaking, flue was too steep, it had not been installed very well. Flue was too steep. The flue seal was leaking, water was dripping down the back, and it wasn't a lot of water, condensate really, dripping down the back and it were going on to the back of the plug on the gas valve and just shorting it out. So, that's a tip for everybody who's going to be doing fault finding. Another thing is, sometimes you'll come to these and they're all rippled. Now, Worcester say if it's got a slight ripple on it, it's probably okay. If it's really bad, sometimes they start to leak on here. That's nearly always down to water quality and how the boiler has been installed. So, if it was on a heat only boiler, sometimes it's just because it's not had a pump overrun wired in and it's just not been installed correctly. Now, if we're going to service this, normally you would check your fan pressures. So, it says in the installation instructions to check the fan pressures, and you're checking for a negative pressure, and that tells you whether or not you need to strip this down. Personally, if I haven't been to a boiler before and it's more than a few years old, maybe three or four years old, I would be stripping it down almost definitely and I'd be replacing that seal.
