Perfect !!!! Thank you very much for your videos, they are so good and helps a lot especially for new qualified gas engineers like me.

How to service a Worcester boiler. 1: Do a fan pressure test. 2: Pray it’s ok

Great Video, thanks for sharing. Keep them coming fella, cheers👍

Super very helpful video keep it up👍

Very useful video thanks. Don’t think I’ll be cleaning inside combustion chamber....

Top quality as always

Great vid. Needed this in my 1st service. Thank you 😊

Would love to see more videos like this for other boiler brands like ideal, Vaillant, Baxi, viessmann, glow worm ???

Turn the power back stand back and watch the fan blow

Excellent video.

Good job great vid 👍🏽

Excellent 👏👏👏👏

👍👌

Have you serviced one with flue side on. Nearly covering the hatch

Great vids Geoffrey sir... Any chance of uploading a Worcester Compact model service??? Thanks again for sharing.

Ace service Geoffrey!

Bring back floorstanding Potterton Kingfishers!! Happy days!

I'll do a cpa first on combustion and air intake first before doing anything from now on.

Excellent video very informative great for newbies like me who com into the industry recently ,plz upload more videos👍

HI Geoffrey excellent video. I do not fix boilers but your workmanship is a A+. I was going to ask one question my 28i is showing a blue light flashing. The pressure and condense pipe is ok. A plumber said replace it by only looking at what's app. What would you do? I am not going to do work the myself but maybe getting someone else another heat engineer

Muchas gracias por el vídeo me parece muy útil. Te propongo que pongas subtítulos en español para los españoles y los hermanos que hablan nuestro idioma un saludo desde 🇪🇦

If only the fan went back in as easy as that every time 😂

Taking a risk not replacing the washer on the condensate trap, they always leak. You need to highlight better in the video that this service is only done in fan pressure reading is wrong

Most times you wont get the baffels out when it fails the fan test so its a new heat cell

great video! quick question, if you had a low negative fan pressure could that indicate a weak fan rather then the heat exchanger needing cleaning. If so how could you determine which one it is. thanks

Worchester Bosch best days are behind flinging out crap now

didn't check the fan bearing seal. Rule no. 1 don't turn off the boiler the fan will never run again.

Hi, thank you for the video. I have comfort condense version. My degree light keepsflashing all the time. (It display the degree, it displays nothing). Is there something wrong?

Are you giving training? I mean on site or training centre

I know this is a rather stupid point of clarity but when draining down the boiler I assume that you isolated the flow & return - just want to be sure - thanks great video

you got a slight mix going on there in that air section 3ppm & 20.7%. Should it not be 20.9% and 0ppm on air section??? 9:01

Cleaning the electrodes is fatal....

Hi I seem to always struggle to remove the electrodes on greenstar i . Any tips for this ?

Operating with this brush is awkward, and therefore nobody on KZfaq is willing to show properly the process of cleaning a really dirty heat exchanger of that type, and not an almost new one as here. Instead it is always as sketchy and superficial as in this video.

When my boiler was service the engineer basically took off the cover , without removing ANYTHING inside pulled and moved some wires and pipes to vacuum inside, did a co ratio test, did a let by at the meter, looked at the terminal and put the cover back on and was done in about 10 minutes !! Now I know ....

Is it true running hot tap whilst service mode on allows excess heat to escape to prevent overheat during tests? Only worcester i think though,may be wrong

I doubt my Worcester boiler would be serviced to these high standards.

You forgot to pour the heatexchanger with water after brushing it to get the dirt out and also forgot to re-charge the expansion vessel to .75 bar… those you forgot were very important bits as well… goodluck…

I don't understand when you touch the gas valve, that valve is set up when it leaves factory.

Thanks

The flue integrity test should have been done before combustion tests as adjustments to the gas valve if a flue seal is leaking means you have wasted your time and not worked to the standard required. Your flue integrity test would then mean you would have to remove the flue and probably replace the seal/s, then carry out high and low combustion testing all over again, I am amazed you do this incorrectly but more to the point, the reading shows 3ppm CO, so it did fail the test and yet you carried on when the boiler was classed as 'at risk' . Unacceptable practice, at least make it clear that you would be notifying the customer its at risk and needs further work although that will not get you around adjustment of the gas valve when you should not be adjusting it at all until the CO fault is rectified and that's why you do flue integrity before removing the boiler case.

I was trained too take a flue reading with case on even on theses new boilers? As this would give slightly wrong reading? I'm going to do it your way from now on,cheers

Shit and over complicated, and flashing light counting?? Pure monopolists..never recommend it

You had 3ppm at the air intake dude. Must be 0. Flue needs to be checked/replaced.
