Elica Concorde 90CSTSS vibration – motor issues

[CLD40]

This cooker hood was installed in November 2015, and is ducted to the outside. Recently it seems to be vibrating a lot even on low speed, and grease/oil is dripping from the motor. My husband thinks the motor may be out of balance, or defective. Grease filter is cleaned regularly, and frying is minimal.

Questions: Can the fan motor be replaced easily? (Hubby is very proficient with this type of DIY).
Can anyone advise why it’s dripping a yellow oily substance? It’s definitely extracting, as we can feel the airflow from the exterior duct.

We chose this model due to limited space for the ducting; it’s a short run straight through to the wall at the rear.

THANKS!!

may just be a warped fan

Interesting – begs the question, how might it have happened, and how would we know aside from replacing it? What annoys me, is that these cooker hoods aren’t ‘cheap and cheerful’ – I think they are quite pricey for what they are.

Thanks for your input!

also check the original installation instruction and see what size the duct should be. most of the time kitchen fitters ignore instructions and fit 100mm duct but some units specify 125 or 150 mm ducts for air flow and noise reasons

We did the fitting (along with the electrician), and I know we used the recommended duct size, which I think was 5 inch (sorry – I think in Imperial rather than metric). The run is very short – straight through to an outside wall. I asked the other half if there was any possibility of an obstruction – even a wasp nest – and he said no. I can definitely feel air flowing when I put my hand up to the terminus on the outside wall.

It’s been fine for 3.5 years; this is a recent phenomenon.

I know that feeling being on the wrong side of 60 means 5 inch means a lot more to me then 125mm

you need to take it down and strip the motor out. had fans warp and come loose over the years

Given that the fans/motors would be around £100, plus the hassle, I am leaning toward living with it for a while, and then replacing. Seems a shame, but the frustration of stripping down and fitting might push my other half over the edge. We are both on the wrong side of 70, so still think in inches. I can visualise 5 inches, but not 125 MM. go figure. Thanks for all your input; much appreciated.

have you checked to see if you can get the fan as a separate part because from what your describing that’s what it sounds like

the pic is not of yours because I could not find your model in the time I had but it gives you an idea. The plastic rings snap causing the blades to move further out and puts it out of balance

Up to now, I have only found the fan/motor as a single unit (and of course there are 2, so double the joy). This is VERY interesting, and before I hit the “buy” button for a completely new hood, I will check it out.

forget all the websites trying to sell parts go straight to the manufacturer. that way you will know what parts can and cant be got

I checked the Elica shop website, and it’s amazing what they DON’T sell. A halogen bulb was listed for 29.99 euro. Couldn’t believe it! But not one fan. Mostly just consumables like the charcoal filters and disposable grease filters.

either ring them or fill out the form

from what I can see you unit possibly has twin motors

it should be possible to stop one motor to see which one is making the noise

Dave

Well – this is strange. I emailed Elica via the form, but obviously don’t expect a reply until later today at the earliest. And yes, you are correct; this model has twin motors, which apparently rotate in opposite directions. But I digress…

When I came down this morning, my husband was busily making his porridge, with the extractor running at low speed. He had turned it on as usual this morning, said he heard a “clack” sort of sound, and suddenly…..no vibration. OK, so there’s a tiny bit on the highest speed, but it isn’t so much that it’s literally transmitting to the adjacent cabinets.

I cannot remember if this unit has a non-return baffle on the outlet, and without removing the rigid ducting, no way to tell. Paperwork is vague – some have it, others don’t. My only thought is that IF it does, it MIGHT have been stuck in the open position, or closed, or whatever. I really have no idea how, what, or why, but at this point, “if it ain’t broke, don’t fix it”.

Your input has been great, and I appreciate it. Hopefully it won’t revert to “broke” mode, and we can get a few more problem-free years out of the monster. There’s still the ‘grease drip’ issue, but I can live with that unless it becomes giant globs.
