I just turned on my brand new haan. Is it supposed to make a knocking sound???

Yes, it will stop in short time, usually when the water starts to get hot. It will happen every time you turn it on. It is normal!

Yes, but it will stop after a short time. This will happen every time you turn it on. It is normal.

Yup! I don't know why it makes that sound, but it indicates the heating element is working. My old Shark made a similar sound. Go figure.

Mine has a soft rattling sound when I shake it firmly (I just checked)--and it's brand new, working perfectly.

yeah something's wrong then, mine sounds like a jet engine winding up when turned on. And the airflow increases quite a bit from the low to high setting, as well as the feel of suction in the back from the air getting pulled in. Make sure all the filters are pressed all the way in and the back panel is snapped on because it has a safety feature that wont let it turn on when that cover isnt on. If all that is the case and its still not working id return it, the next one will be fine im sure.

Ours made the same noises and I just turned to off and then back on again. Now it seems to be ok.

it does make a rather high pitched buzzing sound. that is actually the "ultra sonic" cleaning. make sure that you push the start button.

I am not sure if it is normal, but mine does make this noise when the lid is open.

I have had this problem a few times. After the cussing and the startle response have settled down, I slapped it back on and pushed it extra hard, that seems to work. I also noticed that the little light on the front never comes on, so I'm wondering if the unit is simply defective.

There should not be any noise other than the sound of the bubbles coming from it? Sounds like you have a defective motor.

I havent installed it yet. My existing was sounded like the bearings were going out so I got one ordered, but it quieted back down. I would make sure that the drain on the bottom is clear so your not getting condensate in the bottom of the fan. If it were a high pitch noise, I would say it is a bearing, but low pitch noises are normally imballance - which could be caused by things like a little rub on a blade, blade manufaturing defect, condensate in the bottom, pluggage on the inlet or outlet, or a slight missalignment. Hope this helps and good luck. Sorry for the late response. I thought this was just junk email from amazon. I havent installed it yet.

Not to my knowledge. Mine has never made a noise of any kind. You should contact the manufacturer or Amazon.

I just walked over and shook ours. I don't hear anything. No... perhaps you should exchange yours for a new one.

Mine is noisy too, a high pitch whirring sound. I wondered if mine was broken as well but it has great suction so I think it's suppose to sound like that :)

Mine does the same thing, makes a loud clicking noise when mixing bread or thick cookie dough. Kitchenaid's response was: "The clicking noise is normal, especially under a heavy load." so it is a known problem. Personally, I would call this a design defect. No other motorized appliance I have ever used made noises unless it was broken. I may opt for a smaller model or a different brand.

Absolutely not! If it's an electronic beep, it's a malfunction. It might be a squeak from the canister turning. Re-position it and see what happens. Keep the canister handle toward the back.

Hate to say sounds like something wrong. I get the idea. Mine isn't that loud, but there is like an air noise, but doesn't seem to be a bad noise. Or hum, like some I've heard. Mine is more just the "perk" noise.Did you buy it from here. How often used? I'd contact Hamilton beach and ask. Since Amazon is merely the holder, Beach should know more the personality of unit.

It's the death rattle. Prepare for a burial. Mine only worked for a month before it started making that sound. It died soon after. Good luck.
