Worcester 24i heating problem

[silkyuk9]

Newbie here

Here is a picture of a worcester combi boiler 24i. Is anyone familiar with this boiler, have one or has had one and had a problem like im going to describe?

Ok, as you see in the picture a combi boiler



Bottom right, the pressure clock, next to that the timer swtich with the on /off and timer button. next to that on the left is the heat control switch, you turn in for the hotness of the water.



Ok, the problem.



There is a switch on the timer, on, off and time setting (like a clock you can set it to go on and off at a certain time) We use the switch to turn the appliance on and off, we never use the timer as we only have heating either on all day or off.



ok, to swtich the combi on the switch is set to the bottom, on doing this the appliance fan goes on, this is a noice hard to describe but the fan comes on, after a few seconds the appliance ignites, you can hear this noise like a 'whoosh' gas igniting kind of noise. Then obviously the radiators get hot and we have hot water.



We have noticed that several times a week, that some times we feel a little cold and feel the radiators and they are cold, the appliance has gone off, so i go upstairs to the boiler and the fan is still going but obviously not working the, lets call it the ignitor as i do not know technical names. So now i can run the hot tap and only cold water comes out, the hot is now not working. The only way to get things back to normal is by turning the boiler off, waiting 5 minutes until the fan dies then return it back to on, and again the fan starts, then a few seconds later the appliance ignites and again we have hot water and the cenral heating is working.



This is an intermittent problem, it happens about 2 or 3 times a week, some days its ok, heating on all day and no probes, but another day the heating can be on from 9am in a morning then sometime on the evening the rooms get cold and we find the heating if off.



This is prob a specialist question, so if there is a plumber out there who knows about Worcester 24i boiler systems and can help please do, or can anyone direct me to a foum dedicated to boler of plumber problems.



If i knew whatt he problem was it helps with financial costs.



Cheers.

This a mediocre quality boiler, typically poorly installed and dito maintenance. Most problems I encounter with this model are due to incorrect install/lack of maintenance, and only a minority to failing parts.

We don't do quotes or prices on the forum, and an estimate on an intermittent fault is pretty impossible any way.

 

[silkyuk9]

I understand that, but the problem is happening about twice a week. and i reallu could do with suggestions if anyone has come across the type of fault or problem im occurring.

 

[bengasman]

The implied suggestion is to remedy any obvious imperfections from the install, and do all the maintenance that is overdue.

We have it maintained by BG every year he has been out last week and changed a grey plastic 'sensor' and said see how it goes. it was ok for 3 days and last night the prob reoccurred. we have an appointment tommorrow with Bg again, but if i had an incling of the prob i could suggest this.

 

[bengasman]

In the vast majority of cases, BG don't service boilers, but only stick a probe in the flue; this probably means your boiler hasn't had a real service for years. Correcting poor install issues is never part of their remit under a contract.
I would not recommend trying to tell the engineer how to do his job; granny, eggs....

 

[silkyuk9]

I understand that. I just have to hope if the problem is not fixed then someone else may have experiaced the same issue. Ive had a message saying its possibley the ignition sencor or the PCB so at least there is some suggestions.

 

[bengasman]

The best suggestion in cases like this is: let the engineer get on with it ( apart from instructing him to do those things that should have been done a long time ago and pay the bill for it) , and if you are not happy with the results he produces, get a better one. If you feel that you need to tell the engineer what to do, it could be argued that you should find a better one any way.
Suggestions of what it could be are pointless in this scenario; I can think of at least half a dozen causes whilst holding my breath.

 

[silkyuk9]

id like to hear the half a dozen

 

[bengasman]

And what would be the point of listing half of all the possibilities?

We dont give gas related advice here.

If you have a BG contract then just get them to sort it out.

If you think that you are more clever than their staff then get a job with them as a supervisor!

Its a simple fault and just needs a competent engineer.

[bengasman]

You could try the button "cancel account". I've never tried it, but it sounds promising.
