Do you guys get a whining sound when the machine turns on and gets ready to work? Sounds like the water pump struggling.

We never shut ours off.... however it goes into sleep mode and when I pull up the the part to release the pod it dooes make a hissing noise which is the extra pressure being released and then is sounds like a slight whining sound while it prepairs itself for the next use. However er have had 2 machines and for several years (gave one to my sister because I wanted a different color) and both did the same thing since the first use and one machine is 3 and the other 1.5 years old. If the sound is very loud I would call customer support. Hope it helps.

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 :)

Ours is extremely noisy when running. We have a basement home theater in the room adjoining the utility room where the pump is located, and it's extremely unpleasant if the pump is running and we're trying to watch a movie. And that is with the utility room door closed.

Mine is a low hum, maybe you need more water in it or the motor could be faulty.

Mine was quite noisy and I thought it had a bad bearing. Technical support told me to check the end of the pump that was perforated since it can be bumped and become cocked and lets the fan hit the housing. He told me to remove it to see if it helped. I could see that it wasn't sitting properly and moved it and it ran with just a hum of the motor turning. Was quite happy.

Mine makes a noise when I press the button like it's building up to steam. It's sort of a gurgling or water popping kind of sound. That's normal. Does that help?

it sounds a bit like someone is on life support under the sink. It isn't too loud or annoying though- it is no worse than a fridge and doesn't operate all the time, only when it is refilling the tank. Do be aware though that IF you have the Home Master RO system you need to buy the permeate pump direct from them as this one will void the warranty.

There is a sound of either the fan or the pump after you turn off the unit by hand. This is normal as the unit de- ices or continues to pump water from the tank if you have the self drain hose hooked up.

I haven't had that problem and I use my machine daily so I would say no, it's not normal. If it's not the outlet (do other appliances work using that same outlet?), the tank isn't empty, it sounds like the machine broke.

Thank you! That was definitely part of my problem. One last question: when opening, I hear a pleasant ratcheting sound, which I don't hear when closing. Does yours not make that sound

When that happens I would turn it off right away and unplug it. Then take a look under the bottom suction area to see if there is something obstructing the flow into the machine.

Mine makes a clicking noise too. I wouldn't mind, but the clicking noise is quite loud compared to the machine running on the "Low" setting. I haven't tried this yet, but maybe it only clicks in "Auto" mode? I didn't notice it for the first few days when I had it running on High all the time.

hahaha.... yea... i had that problem at first too and was quite annoyed... there is a switch on the back side covered in a plastic/rubber casing. You have to switch it on and won't know until you actually power on the machine. It only lights when you run the machine so it's a little confusing that way. Hope that helps!

I don't know if I would describe it as whining but it does make an unusual sound at the lowest setting. It doesn't bother me enough to refrain from using the fan.

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

I had the same noise on mine and found out it was the positioning of the pump that was the problem. I had the junction box part of the pump in the 12 o clock position with the pump horizontal. I turned the pump so the that box went to the 6 o clock position and the noise stopped and never came back. It could also be air in the system. Hope this helps. Dave

Mine started doing this after having it about 6 months. Was about to buy a new one but then read this post. So I cleaned mine and then added white vinegar to it to possibly break up the oils in the bottom and throughout machine and it started working a little bit at a time. When it turned off I would just turn it back on again, kept doing that till it started doing a full cycle. Yay super excited I didn't have to buy a new one or the replacement part.
