00:00:00.000 hey welcome to eating geeks in this 00:00:02.72000:00:02.730 video here I'm gonna show you a Raven 00:00:04.64000:00:04.650 heat boiler that all it needed was a 00:00:06.47000:00:06.480 little bit more time spent on it by the 00:00:09.29000:00:09.300 previous engineer if we had had um met 00:00:11.48000:00:11.490 the boiler would have been fixed but you 00:00:13.66900:00:13.679 didn't so that's where I come in 00:00:15.53000:00:15.540 and I went there and got the boiler 00:00:17.12000:00:17.130 fixed enjoy it 00:00:19.51900:00:19.529 happy Father's Day to all the dads out 00:00:21.29000:00:21.300 there I've got three boys here myself I 00:00:24.08000:00:24.090 have plenty of plenty busy that's for 00:00:26.87000:00:26.880 sure 00:00:27.23000:00:27.240 anyway enjoy the video 00:00:31.22000:00:31.230 [Music] 00:00:44.13900:00:44.149 I hear y'all today this Ravens eat 28 00:00:54.93900:00:54.949 flashing don't know what that means is 00:00:58.18000:00:58.190 this one but this one has two reports on 00:01:01.84000:01:01.850 it 00:01:02.61000:01:02.620 no news you're not ready we can't be 00:01:07.12000:01:07.130 it's not most call it things I say let's 00:01:11.35000:01:11.360 have a look 00:01:11.98000:01:11.990 get into and see more suave 00:01:19.05000:01:19.060 so here we are covers off inside it so 00:01:22.60000:01:22.610 do my usual thing of looking at 00:01:24.70000:01:24.710 everything so we've got flu stat quite 00:01:27.42900:01:27.439 electrodes this we spark 00:01:30.42900:01:30.439 that'll be rectification we have an NTC 00:01:34.27000:01:34.280 and overheat gas valve we have a firm 00:01:38.62000:01:38.630 with two plugs on it so that's going to 00:01:40.33000:01:40.340 be 240 and 24 volt 00:01:42.70000:01:42.710 they'll be 24 volt they look control 00:01:44.83000:01:44.840 stuff and that we 240 down there to make 00:01:46.84000:01:46.850 it run spark generator there we have the 00:01:52.84000:01:52.850 bits that probably run so let's open 00:01:58.19900:01:58.209 this up so we can have a better look 00:02:00.63900:02:00.649 inside there but as you can see this top 00:02:03.19000:02:03.200 section nothing new in there also normal 00:02:06.55000:02:06.560 bits and bobs you see in boilers where 00:02:09.85000:02:09.860 there's this watermark on it but anyway 00:02:12.07000:02:12.080 worry about that after assuming get the 00:02:14.58900:02:14.599 thing to work actually right now I don't 00:02:16.83900:02:16.849 even know what this fault code is so I'm 00:02:20.22900:02:20.239 actually to look that up using the data 00:02:22.05900:02:22.069 badge to find the manual so but Raven 00:02:26.94900:02:26.959 eat technical are very good so Devon eat 00:02:29.92000:02:29.930 all you McCall okay so I panels come off 00:02:34.21000:02:34.220 nice and easy it's great access how this 00:02:41.43000:02:41.440 comes out let's give us room to have a 00:02:44.62000:02:44.630 look well let's look at the forecast 00:02:46.63000:02:46.640 there is something by the way the reason 00:02:47.89000:02:47.900 I'm going in here is someone's ordered 00:02:49.30000:02:49.310 up a diaphragm a diaphragm or a micro 00:02:53.94900:02:53.959 switch so somewhere in there it's a 00:02:55.18000:02:55.190 pressure differential switch for the 00:02:56.83000:02:56.840 pump I think pump or even switch so I'll 00:02:59.92000:02:59.930 just find that somewhere in there but I 00:03:04.15000:03:04.160 will let me look up this first one they 00:03:05.97900:03:05.989 let me have cut this fault here go on 00:03:09.28000:03:09.290 give it a click 00:03:10.56900:03:10.579 it's not gonna hurt is it there's 00:03:13.53900:03:13.549 default code okay so this does mean pump 00:03:18.75900:03:18.769 proofing error so I'm gonna get this lot 00:03:21.87900:03:21.889 out 00:03:24.64000:03:24.650 and uh and see if there is a problem at 00:03:29.69000:03:29.700 a pump but so far it was nothing too 00:03:33.83000:03:33.840 stressful here and see how this PCB box 00:03:36.41000:03:36.420 comes out okay so this doesn't actually 00:03:42.01000:03:42.020 it was very much room here the thing 00:03:45.59000:03:45.600 that we need seth has been ordered you 00:03:49.46000:03:49.470 can't really see let me move the phone 00:03:50.99000:03:51.000 I'm gonna flip you upside-down and it's 00:03:55.79000:03:55.800 back there if you look that is the 00:03:59.30000:03:59.310 microswitch there some crusher diff is 00:04:05.33000:04:05.340 there coffee on the pump this look for 00:04:07.28000:04:07.290 you again 00:04:07.61000:04:07.620 I have enough on the line there's the 00:04:18.56000:04:18.570 pressure diff little bit all got ice 00:04:23.33000:04:23.340 there 00:04:24.13000:04:24.140 yeah yeah I'm guess you pulled up on 00:04:28.13000:04:28.140 power for that you got you've got be 00:04:30.59000:04:30.600 taking that pump out to get to that it's 00:04:32.87000:04:32.880 fresh in this situation there if they 00:04:35.24000:04:35.250 have to so this let's test it to make 00:04:39.02000:04:39.030 sure that is the fault though okay so 00:04:44.05000:04:44.060 this is the pressure difficult there's 00:04:46.40000:04:46.410 the water pressure switch there and 00:04:48.04000:04:48.050 here's the mics which off the pressure 00:04:52.07000:04:52.080 differential so this is this these two 00:05:00.05000:05:00.060 are you know daisy chained together 00:05:02.03000:05:02.040 so in theory if we were to test across 00:05:05.54000:05:05.550 the this white connection here and the 00:05:09.62000:05:09.630 blue connection back here we should have 00:05:12.98000:05:12.990 continuity okay going through both of 00:05:16.73000:05:16.740 these switches if we have that we won't 00:05:21.08000:05:21.090 have it initially what I'll have to do 00:05:23.02900:05:23.039 is go test on the pushed and my 00:05:24.65000:05:24.660 extrusion here to click it and if we 00:05:26.87000:05:26.880 then get continuity through all of that 00:05:28.82000:05:28.830 together let's go right here if we then 00:05:32.83900:05:32.849 got 00:05:35.12000:05:35.130 if we then get continuity across all of 00:05:38.31000:05:38.320 this lot we know the wall pressure 00:05:39.81000:05:39.820 switch is good and this micro switch is 00:05:41.82000:05:41.830 good okay so then what we will do is we 00:05:45.00000:05:45.010 will get the pump to run and make sure 00:05:46.89000:05:46.900 the pin comes out of the pressured if 00:05:49.50000:05:49.510 switch at the back there if the ping 00:05:51.90000:05:51.910 comes out great if it doesn't then its 00:05:54.45000:05:54.460 pump out get the pressure dip and see 00:05:58.05000:05:58.060 what's going on with it 00:05:59.07000:05:59.080 so first we're going to do a self-test 00:06:00.84000:06:00.850 for this the wall pressure switch and 00:06:02.79000:06:02.800 the pressure differential switch so we 00:06:06.03000:06:06.040 always set up on them right 00:06:09.38000:06:09.390 so that is 41 that's what we want killer 00:06:14.40000:06:14.410 ohms 00:06:14.94000:06:14.950 now I'm gonna click the mic switch yeah 00:06:25.89000:06:25.900 so that shows the the war pressure 00:06:28.74000:06:28.750 switches doing what's meant to do and 00:06:31.56000:06:31.570 then when this clicks this is doing what 00:06:34.44000:06:34.450 it's meant to do this micro switch okay 00:06:36.12000:06:36.130 I'll contain that of resistance cross 00:06:37.92000:06:37.930 these leads on one more with mirrors 00:06:39.57000:06:39.580 about one-and-a-half ohms so that point 00:06:42.09000:06:42.100 has been that one point three ohms now 00:06:45.29000:06:45.300 you can hear that click nicely so that's 00:06:47.67000:06:47.680 what I'm doing okay 00:06:53.09000:06:53.100 and so these these are these two 00:06:58.41000:06:58.420 sentences being daisy chained here okay 00:07:01.29000:07:01.300 it's just like other boilers like for 00:07:04.74000:07:04.750 instance the Worcester green star the 00:07:08.49000:07:08.500 Worcester green star jr. off the top of 00:07:11.37000:07:11.380 my head that that is the flu sensor and 00:07:13.59000:07:13.600 the green overheats down the heat 00:07:15.33000:07:15.340 exchanger are daisy chained like this so 00:07:18.99000:07:19.000 you test both in one go 00:07:21.17000:07:21.180 I've a Worcester the old jr. that was 00:07:23.94000:07:23.950 that junior RSF that's got the warp 00:07:27.36000:07:27.370 pressure sensor and the overheats down 00:07:28.95000:07:28.960 the top right that heat exchanger that 00:07:30.54000:07:30.550 daisy chain just like this so basically 00:07:35.19000:07:35.200 it's quite easy to to test them so it 00:07:38.79000:07:38.800 smoke ways it's then linked stuff out to 00:07:41.01000:07:41.020 make the boiler run sis or 240 volt 00:07:43.08000:07:43.090 stuff you can just link it out and if 00:07:46.74000:07:46.750 the boiler them runs and fires and runs 00:07:48.84000:07:48.850 fine you know you've got a sensor issue 00:07:51.84000:07:51.850 I wouldn't recommend you do it but it's 00:07:53.43000:07:53.440 just something you can do I saying that 00:07:58.89000:07:58.900 I might do that here just to get just to 00:08:00.78000:08:00.790 prove that this isn't blocked and the 00:08:02.67000:08:02.680 pump and all that's working currently or 00:08:04.47000:08:04.480 may just do that and let's get it 00:08:06.57000:08:06.580 running and have a look and see if you 00:08:09.18000:08:09.190 can see the person if they're just 00:08:10.62000:08:10.630 hiding see if that pin moves out that 00:08:13.74000:08:13.750 pressure diff 00:08:22.98000:08:22.990 I'm trolling me like that pinned down 00:08:29.17000:08:29.180 nicely it's just 20 I again though oh 00:08:33.79000:08:33.800 that's okay it says 28 because the I 00:08:36.57900:08:36.589 have the thing not connected to this 00:08:40.82900:08:40.839 let's try and focus on this a little 00:08:44.35000:08:44.360 reset this boiler turn the power back on 00:08:54.87000:08:54.880 that pin moved out that move back in 00:09:02.40000:09:02.410 right that seems to work something for 00:09:05.07900:09:05.089 me so we've got 28 again so let's put 00:09:07.93000:09:07.940 the mic switch back on I'm running 00:09:29.60000:09:29.610 or this early you know catch 00:09:34.84000:09:34.850 you know talk to the customer I could 00:09:39.19000:09:39.200 hear what going through all of this 00:09:40.54000:09:40.550 nicely they obviously any air you can 00:09:44.32000:09:44.330 hear air but any air will limit the 00:09:46.54000:09:46.550 effectiveness of that diaphragm so what 00:09:51.61000:09:51.620 was tower would happen if the external 00:09:54.88000:09:54.890 controls stopped calling for heat so 00:09:57.45000:09:57.460 then a widest is wide like this but 00:09:59.80000:09:59.810 that's the external controls there so if 00:10:03.01000:10:03.020 I turn this off by valve sure close 00:10:30.18900:10:30.199 elves obviously opening or he clicks 00:10:32.80900:10:32.819 when the step that pump kicked in 00:10:44.13000:10:44.140 [Laughter] 00:10:47.47000:10:47.480 and so let's try that again shall we 00:10:49.38000:10:49.390 turn that off 00:10:53.13000:10:53.14000:10:54.41000:10:54.420 right away it lost its demands 00:10:56.61000:10:56.62000:11:03.04000:11:03.050 that light is a lawnmower 00:11:05.75000:11:05.760 that is known or what mister this song 00:11:13.34000:11:13.350 turn that back on love Harriet line 00:11:20.36000:11:20.37000:11:37.86000:11:37.870 so the long tones are expired in there 00:11:40.90000:11:40.910 anyway I've left this running for a 00:11:43.69000:11:43.700 little long and you can see this issue 00:11:49.08000:11:49.090 obviously I'm gonna drive in on the 00:11:51.19000:11:51.200 vessel but what's funny is I've done a 00:11:53.98000:11:53.990 bit of digging I found out a bit more 00:11:55.27000:11:55.280 information okay so what happened here 00:11:57.58000:11:57.590 was the boiler continually lost pressure 00:12:02.67000:12:02.680 and every few days the customer had 00:12:04.81000:12:04.820 stopped the pressure up and reset their 00:12:06.61000:12:06.620 28th flashing here okay now that's 00:12:09.64000:12:09.650 probably the cause of that and the 00:12:11.68000:12:11.690 engineer knows why that's done that and 00:12:13.33000:12:13.340 what's gonna happen and why there'll be 00:12:15.31000:12:15.320 no war and it in a little bit so I'm 00:12:17.41000:12:17.420 gonna fix that issue so what happened 00:12:22.09000:12:22.100 was the engineer came and replaced this 00:12:24.51000:12:24.520 okay because this had stopped working as 00:12:26.77000:12:26.780 far as they are aware now what I think 00:12:28.78000:12:28.790 happened is when he replaced this he 00:12:31.12000:12:31.130 introduced a lot of air into the system 00:12:32.89000:12:32.900 or into the boiler which is what we 00:12:35.38000:12:35.390 could hear when it was first trying to 00:12:36.67000:12:36.680 run and pressure differential switches 00:12:44.11000:12:44.120 just not only takes pressure 00:12:46.61000:12:46.620 differential switches but that one back 00:12:48.77000:12:48.780 there don't like air any bit of air can 00:12:52.10000:12:52.110 cause it lots of sense because the airs 00:12:54.29000:12:54.300 are consults on it it absorbs the 00:12:57.05000:12:57.060 pressure from the pump 00:12:58.49000:12:58.500 so pressure differential switch won't 00:13:00.23000:13:00.240 see it so anyway let me deal with this 00:13:04.03000:13:04.040 this pressure issue this rising which 00:13:07.55000:13:07.560 that's an engineer will notice quite a 00:13:08.90000:13:08.910 basic thing so I want to get on with 00:13:12.68000:13:12.690 that and then retest to boil up when 00:13:16.67000:13:16.680 ugly field is born are after dealing 00:13:18.20000:13:18.210 with that issue I'm going to vent the 00:13:19.67000:13:19.680 pressure from the air out there time to 00:13:24.38000:13:24.390 get over there so just for your
