Glowworm Micron 30FF stopped working - fan/APS issue?

[CaptainNonsense]

Hi there

I wonder if anyone can offer me advice about my boiler. I have an old Glowworm Micron 30FF. Must be about 18 years old. The whole system needs replacing if I am honest - the tank it fills is not in good condition. But right now money is really tight and anything I can do to get a few more weeks or months from the current system would be worth considering.

Having gone through the manual's trouble shooting, the LEDs indicate Fan/APS issue. The unit sounds like it powers up when I switch the hot water or heating setting om (there is a quiet but audible sound coming from the unit), but no hot water goes to tank or radiators. The boiler gets very mildly warm to the touch, which I assume is just the pilot light, as it can get much hotter.

Prior to this issue, for about a year it was rattling very loud - more audible outside the flat than inside though.

I know I should have dealt with this long ago, but the cost has been prohibitive.

I am not a DIY expert by any means but is there anything I can do myself to get the unit running again, even for a few days or weeks while I look into replacement options and try to beg borrow and steal the money!? It's pretty cold out there right now!


thanks so much!

Update

I opened the regular front panel - not the interior one that you refer to - to reveal the fan, which appears to have seized up. I sprayed some WD 40 and turned it on and it worked! Fro about 30 mins. Now it has seized again.

So I am pretty sure the issue is the fan - it will probably need replacing. I saw a youtube video of it being done without opening the combustion chamber. But I am not sure if I need to buy the whole fan which is about £200, or the fan assembly which looks like it costs about £50.

In the meantime though I would love to work out how to get a few more days out of it!

If you can access the fan then you have opened the combustion chamber on that boiler so sorry we cant give you advice on gas work it is against site rules

Is that 100% the case?

Perhaps I don't understand what the combustion chamber is but I can access the fan as soon as I open the front panel.

It looks like this diagram as soon as I remove the front panel - in pink I have highlighted the fan and also what I understand to be the combustion chamber, which remains closed off, with a sticker on it telling me not to open it

I also took this screenshot showing what the unit looks like as soon as you take the front panel off, and how you can immediately access the fan. It is from a poorly shot video on youtube for reference, again highlighted in the same way:

Have I misunderstood and is the whole thing the combustion chamber? I thought it was just what is behind the dark panel in the image below.

yes on that boiler the front cover is the combustion seal, not on all boilers but on yours it is
