If you ever have the worcester with the vent tube on top of the kebab heat exchanger.. what I do it drain the boiler at the point by the diverter. Then put the vent tube into a bottle of system cleaner, open the vent tube and syphon all the cleaner into the boiler..... pressurise the boiler, isolate flow and return, and run the hot tap on low temp and it will flush just the plate out.. Once it's been ran for a while until temps are stable on high... flush cleaner out and open flow and return valves... always works for me..
I knew about that strategy mate but for some reason didn’t associate it with the plate, I just assumed it cleaned out the main hex.. what a donut haha. Thanks for the advice Brendan! 🫶🏽
Good video. Worcester Bosch Plate Heat Exchangers are not the easiest repair on them old ones. The new Worcester Bosch 4000 is amazing though. Really good video for Trainee gas engineers. Thanks.
All plates can be cleaned using similar chemicals,they're mostly made by specialist companys. A tip I was given was measure hot outlet and return temp and expect ideally 1c diff. Yes advise power flush and filter if not fitted. Top tip 2litres of the best known inhibitors is the ideal on average property, it will bring the ph closer to to neutral ph.

Mint video Dan, I use a acid called Jebsol lethal stuff mate but does the job. All honestly In 16years I’ve never swapped a plate always cleaned Keep at it Hustler 👊🔥
finding drain acid hard to get now. idiot students round here are forever letting the plastic covers from razors go down the plughole. bit of hair and that acid problem gone..... it is nasty stuff used in the wrong place i agree. but it had its uses.
I used to work for Worcester and in my opinion the 25. & 30i ERP is the best model Worcester ever made. The easiest way to test a plate blockage is to measure the flow temp by the display temp and then measure the hot water outlet temperature either at the tap or pipe underneath. The temperature difference should be 10 degrees max. So if tap reading 50, boiler should display 60. If more than this like 20 degrees etc, plate is blocked. 👍
Thank you Kev, would you say this method above only works on Worcesters or all plates? I was always taught to measure the flow and return difference in the boiler like I’ve done on this.
All boilers are different. Manufacturer specific. This as far as know only works for Worcester. Ideal you would test return temp and hot water outlet temp, less than 5c is good, 10 or above etc would be blocked. I’ve done a video on the ideal on Allen hart channel ages ago.
Mate, just come across your videos, as a Gas engineer they're very informative to watch. As we like our tools, that little gadget you got for the silicon grease where can I get one, looks mint!?
Another way and tip I do to remove the plate from Worcester’s is taking off the left hand manifold and the pipe that links from the hot water out and it comes out soo much easier
Hi, thanks for always great videos, just a simple question, have you listened to your videos? The music is too laud and when using headset it's going to make you deaf.
Yes I edit the videos so I do listen to them. Do you mean the intro music, I think that’s the only music I’ve had on for a while. If so, I’ll look to try and turn that down mate . Thank you. 🫶🏽
Wooster Wooster. Why do you love them so much Dan. They really dont love you. 😂. Good content pal.. As others have said, i think cutting the hot pipe is probably a bit easier. But as you stated baxi plates vertually just slide off on their own. Lol
Another tip to get the plate out. Remove the hot pipe connection from the boiler and the plate wil drop out. I think Geoff needs has made a video on how to do it. Dead easy
Just be careful on worcesters, youve got to realise that boiler can only produce approx 11l per min, if your opening up that hot tap fully at start, it looked alot more than that and the heat transfer wont happen and cause the boiler to overheat. Its one of the biggest callouts i get and when i tell customer to turn hot tap open a quarter of way it will give the heat transfer the best chance and pretty much make boiler stay on. Also worth noting on those 30i erps, the diverter motor/paddle tend to get weak and put heat down the flow due to blocked plates. In my opinion, there one of the worst theyve made, cdi range is so much better. Good video though mate. I would never use acid, just replace. Ive seen blokes getting some nasty burns.
Thanks Steven, good call on opening the tap up full at the start. I’ll not do that in the future. Yeh I’ve heard about the paddles. I’m Not sure if you could see but I kept putting my hand on the flow pipe to check it wasn’t seeping down there, thanks for the advice mate 🫶🏽

Listen to Alan he's the daddy of youtube!! Love your work guys keep up the good contents both of you
Another top job Dan. It is a shame the obstacles in the way of the plate make you have to cut pipe work or remove the pump assembly ❤
