Glow Worm 15 HXI

[Dannypipe]

Hi all,

Just had a call from a client. Her boiler has gone on the blink.

The boiler is displaying the water temp' on the LCD display. (24 to 25 alternating).

However won't fire up.

The thing is. I serviced the boiler about two months ago....and it went on the blink about a day later. I went back to the property, and opened up the board to check all the connections. I did this as the leads to the boards are all very cramped and when you swing the door down to service the boiler, they move.

So I did this, and then tried firing the boiler up. It switched on and fired up fine.

So now it's been a couple of months, and it seems that the same problem has occured. I'm going to go there tomorrow, and get it sorted. I'm not too sure it can be a loose connection again, or that it was in the first place. Maybe just a coincindence.

Anyone got experience of this boiler and common faults. It's the first one I've worked on, and I'm not best impressed.

Cheers.

they are quite rubish, they normaly come up with an "f" an then a number when they lock out, never had one do what you are describing. Does the pump run or anything?

 

[Dannypipe]

Haven't been over there to check it mate. Last time, there was no F code. She's just called me ten mins ago, so I thought while I was on the laptop I would pick the collective brains of the forum!!

I will check it through tomorrow, but I can't get to her until late (as her call has just come in) so I would like to turn up armed with the likely suspect part.

My guess at lack of F code is a dodgy board....we all know how much merchants like you returning them!!

 

[Dannypipe]

Just to add, there was no F code, and the LED that signals ignition or demand )can't remember was also not lit.

Should add, when I serviced it, I changed the spark electrode. Was gonna change the flame sensing probe, but changed my mind. Still have it in my shed, as I couldn't be bothered to re-stock it.

 

[Dannypipe]

Well, got a call today from the client.

The boiler has started working again....all on its own. Don't you just love intermittent faults!!?

Will let all know what's wrong with it, if it packs up again. Saved me going over there at 5pm, so I'm happy.

Most likely an external control I'd think Dannypipe. Sounds like no demand to boiler ... ?

thats what I was thinking and perhaps the 24/25 was the temprature

Only thing I'm not 100% on with these boilers is whether the display defaults to pressure when in standby and displays temp when a demand is present?

Thats because the cxi and sxi are sealed system boilers but the hxi is heat only open vent

So it displays temp only quality yeh?

got some training info on the older hxi the one with the small lcd display will try and private message it to you

[Dannypipe]

Yeah, I think it is a demand issue myself now.

I've had a hellish day, and am pleased that it's working again, but I just know it's gonna go again.

What's thrown me in that is started going wrong after I serviced it. Could be a coincidence.

I'll have to check the programmer and the motorised valves.

Its a sealed system BTW. Is a heat only.

I don't have much experience of this boiler. I service two of them for clients, but this is the first one I've had an issue with. I figured someone might have seen this fault before.

I was pleased to not have to go and check today.

I was fitting an inbuilt mirrored unit into a wetroom I installed today. Turned round to get my drill driver to screw it in, and boom, it crashed to the floor. Wrecked. £400 to replace. Great!

Cheers for all the comments.

Oh and yes seems to only disply temp' so probably is a demand issue.

 

[diamondgas]

OUCH!!!

That'll hurt the pocket I hope the custard was understanding

 

[Dannypipe]

Understanding yes, nice client. I still have to stump up for the unit.

It put a tiny scratch in the loo, which I think I'll get away with and luckilly didn't break or scratch a tile (which is lucky as there is electric underfloor heating beneath).

I've ordered another one. Told my supplier my woes and hoping they will do it for me a bit cheaper. Yeah bad day.

Why PM it? The info could be valuable to others.
I thought this was the GSR forum and this info was exclusive to GS registered engineers. Or am I wrong again?

 

[Dannypipe]

Cos its a PDF so he's sent it as an attachment.

will try and put it on the gas engineers page when i can just getting used to the forum.not posting on the open pages as dont want non gsr accessing it

[Dannypipe]

Just looked at the PDF's and they'll be getting saved in the data bank of info I keep on the work laptop!

Brilliant stuff. Cheers!

Would be good to share with all if poss.
