It is making an intermittent noise and the jellyfish are not moving so much. Please give suggestions to resolve this issue.

Check the water level. It's very important that the level is at the top or it will do what your describing!

I trashed mine almost immediately. Never could get it to work. Piece of junk!!!!

It could be the pump rotors are beginning to rust and expand like I mentioned in my review. When this happens, they start scraping and making noise, and the water circulates less. There is not much you can do about it.

it doesn't "bang" shut but there is a noise. I suggest going to a pet store where they are on display and testing out

If the backup pump doesn't run for more then 10 seconds ( in think), it will not sound. Hold the float up for more then that time to test

It sounds like theirs air getting in somehow? If it's sucking all water it shouldn't put out bubbles

I bought two of these jellyfish and have just tested both bases (I only keep batteries in one) the LED bases both work fine. Very bright color change which is about every second and includes blue, red, purple and green and also a combination of colors. Be sure you are using a name brand battery which may give you better results. I use Duracell. The light is bright enough I could read by it and after a short while of having the LEDs on when switched off the jellyfish glows on its own for a while. I often use mine as a nightlight in my bathroom. If you think your LED is defective I'm sure the company would send you a replacement. Good Luck.

This is an AWESOME product! There IS a hum when it's on, but not horrible. The worst noise occur when the water goes below fill-line, but that's an easy fix once you add water. Took 5 days or so for the jellyfish to get in correct position, but they did progressively better each of those days. Just didn't want buyers to freak. :)

Start with a lower water level and see if that helps. The only times mine has not stayed on for several hours is when the water level was too high.

I just bought this unit in December and I have the exact same problem. I love the unit. It is on my bedroom carpet so I am going to try to put a mat underneath it to see if that helps and I will try to change the water level a bit as another person suggested. My guess is that the water sensor works well and the system needs to be level. Someone else told me to put it up at the highest setting and that may help. I really don't want to have to replace it and its too late to return. It really is an awesome unit. Looks great too

No, it is not supposed to make a sound unless engaged. Send it back for another one.

No, return it or better yet ask to have a new plug shipped to you, pretty sure that would work. Our table is my 13 months old favorite toy, she absolutely loves it. It's perfect and small for her. We have a bigger sand/water table and she has no interest. I highly recommend, worth replacing and not totally returning.

We had a similar problem. There was a slippage inside. I am not sure what was done to it, but it is working now. Ours happen when it was brand new. We thought something got knocked loose during shipping

You may need to clean it again. Besides the main piece, there's a smaller rod that pulls up that also needs to be wiped clean. Since it can't be removed for cleaning, I use one of those electrostatic dusters. The first time I noticed the crackling sound, I cleaned only the main part and the crackling continued. Once I cleaned that smaller rod, it stopped. Hope that's helpful.

send it back. If it was working you world hear it. It is not a quite machine.

I had and still have a little problem with the sound. I haven't taken it under water so I can't give you an answer to the second question.

It is kind of noisy - like alot of gears grinding, but no vibration. Once it's in the water it is pretty quiet. I'm not sure if that's what you're hearing, but if it sounds like something is wrong and it's vibrating there may be a problem with the motor.

Waste of money, the jellyfish mood lamp, jellyfish sat on the bottom and the motor made loud noises....this after following instructions to the letter.

It shouldn't be that loud! Mine is roughly a month old and it's only "noisy" when it it isn't full of water. Try filling to the max, if that doesnt help try cleaning the motor. Other than that it could be a bad motor......
