You can remove the flow restrictor on a 42 cdi and get a much better flow rate and its not dangerous as some people think The only issue is you will get a slightly lower temperature rise as the waters passing through the plate faster which you may notice in the middle of winter when the incoming mains temperature is lower
O you won't believe, the times I've gone back and told the customer, that " Think I forgot my screwdriver on top of boiler 🫣" just to make sure, that the cap is on.. 😅
Is this the sort of thing you can fix without replacing rhe whole fan assembly or no? Or is it a tell tale sign the fan is completely knackered and needs replacing?
Noise comes from fan impeller with worn out. Not repairable. Only PCBs on these fans, SOME engineers prefer or attempt to replace. Maybe works but not advised by manufacturer
@@BoilerMend Worcester bosch 37cdi Heating works fine , when i run the water slowly its fine , when i run the tap fast , the blower fan then speeds up and the green light goes out. Multiple times EA fault. Symbol appears. If i run tap for 2 to 3 min slow flow i can then run the tap fast and the fan speeds up and the green light stays on . At no piont does it over heat.
Terrible practice to just bend the gas pipe down and out! Remove the trap and then unscrew the pipe from top of gas valve, twist round and then pull down. Zero chance of damaging it!

Thanks for the info. One question. How is it related to this video? And a noisy fan?
Photo of the flue sample point back on is a neat idea, funny how you can convince yourself you forgot.

Great video again f Raj 👍🏽
Does the gas regulator/ air intake were it mounts to the fan on the side , should you be able to see through or should it have agromet
Talking about a Cdi. It can have a Foam Grommet in some models. But, not essential. Absense of this, should Not effect the combustion/readings.
When my gas bioler runs in fast mode , it blows out. If i run slowly for a min or 2 , then switch tap on it runs fine
Hi.
Apologies, I couldn't understand your question. What is fast mode? And blows out means it blows the fuse? Overheats or or leaks?
And please also advise of what boiler, make and model do you have? So I can try and answer your query 😌
