hen you turn on the machine, there is a normal “humming” sound that its supposed to be only when its turned on; however, it keeps making that sound when the machine is on standby and not sewing. When the machine is sewing it doesn’t make this sound, but the natural sewing machine sound. I don’t know how bad it is, because the machine works perfectly fine otherwise. I just don’t want to keep using it like this, if there is indeed some issue with the machine, that I could keep doing further damage.Any insights would be appreciated. Thank you!

I also might be something very simple. It might be that your bobbin winder is one. Some Berninas have a separate bobbin widing motor. isf the lever on the top of the machine is pressed to the left your bobbin winder will turn on even if you aren’t winding a bobbin. Push it to the right and it will turn off….. and your humming should go away.

Often, this sound comes from not getting your thread in the take-up lever while threading. If you have a new needle that is the appropriate size/type and your machine is clean, but you start to hear a clunking sound after rethreading, this is the first thing to check. And it`s such an easy fix.
BERNINA is producing their sewing machines in two factories. In Steckborn, Switzerland, we are producing sewing machines since 1893.
Why is my bobbin making a clicking noise? If you notice that your bobbin is making a clicking noise, it may be due to lint or oil accumulation on the needle bar or hook. Follow cleaning instructions from your machine manual to clean the hook and feed dog, and check to see if the machine needs to be oiled.
This can be caused by several things, such as a thread getting tangled, the fabric not being fed evenly, or a build-up of lint or dust in the machine. Jams can also be caused by the needle hitting something inside the machine, so always keep an eye on the needle while sewing.
If the needle won`t move with the clutch engaged, unplug the sewing machine and check the drive belt. Replace the drive belt if it`s broken. If the drive belt is okay, an internal drive gear failure is likely preventing the needle from moving.
These can be reduced by changing the way the machine is mounted and introducing damping in between the mounting point and the machine itself. In the same way, vibration of the machine panels themselves can also cause noise to radiate outwards, but can be reduced by adding damping materials to reduce this vibration.
BERNINA, a premium manufacturer of sewing machines, got its start 127 years ago in Switzerland. Today the business remains a family-owned company in its fourth generation, operating in the United States for nearly 50 years.
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn`t budge, your bobbin tension is too tight.
Use a nylon brush to collect all the dust and get in between all the nooks and crannies. (Don`t use compressed canned air and blast inside your machine as this will further wedge debris inside.) If you have a bobbin case, take that out and clean thoroughly. Also make sure to get inside and in-between the feed dogs.
Those noises are a signal that something is jammed or rubbing. How long has it been since you cleaned and oiled your machine? Even if the machine had been sewing along just fine, a tiny bit more lint or a single thread can be the “thread” that “breaks the camels back”.
If the machine is making a rattling noise every time the machine runs, it`s a sign that something is loose. This may be internal, such as the mounting for the water pump coming loose, or it could be external, such as the access panel for the machine coming loose.
Check the drum and clean the pump

If there are rattlings noises during the washing during the washing program, there might be some foreign objects in washing machine drum or in the drain pump. Please check the drum for objects which might get in with your clothes and then check the drain pump.

I bought a Bernina sewing machine in USA but I took it to Colombia South America. The machine works well, but it makes noise when not in use. When you turn on the machine, there is a normal “humming” sound that its supposed to be only when its turned on; however, it keeps making that sound when the machine is on standby and not sewing. When the machine is sewing it doesn’t make this sound, but the natural sewing machine sound. I don’t know how bad it is, because the machine works perfectly fine otherwise.

Couple of guys tried to help me on this, perhaps you guys could come back. I forgot to mention there is a pressure tank bladder type on the discharge side. Could the air in this tank be messing with the prime. I checked the intake. It has water in it after bleeding air from the discharge system where before it was dry before purging air. I think there is air in the system and wonder if it is coming from the pressure tank?. i open up one of the discharge valves and a lot of air comes out. Should I put a valve on the pressure tank to take it off line until I get water from the well?

Mar 12, 2010 – Could it be the check valve? I took it off and the flap appears to be working correctly. This well has been here a long time. Never given me any problems. I do have galvenized couplers on the discharge and intake sides. Old. Could these be leaking even though they show no sign of water? The discharge is able to hold 30 pounds easily overnight. I do not hear any vacuum in the intake when I take it off. Could the pipe to the well have a leak? I know I would have to insert a sleeve but I do not want to go through the hassle if I do not have to. I had put on a brand new pump from the hardware store that did the same thing so I think that would elliminate the pump as being the problem.
I disconnected it for the winter and rehooked it up. The galvanized couplers on the discharge and pump side are old but do not appear to be leakeing as I taped them well. The check valve seems to be functioning well as I took it off and the flap works correctly. The well is not pulling water. there does not appear to be a vacuum on the check vale when I losen it. could the check valve be bad? I am aware I might have to resleeve the well, but do not want to hassle with this if I do not have to. I want to eliminate everything else first. i put another brand new pump on it to see if it was that. That partiuclar pump which was the same thng did not work either.
I took the pump nose off and looked at it. The one way valve appears to be working fine. The impeller is working fine also evidenced by when I turn it on witht the discharge cap off, water shoots out. When I open one of the discharge valves and turn it on, the pressure drops to 10lbs. At this point the prime water has moved through the pipe and and the pump does not soound like it has any water in it. I pull the cap off and have to “reprime it again.” It again goes back to the pressure gauage rapidly fluctuating while pump on. I disconnect pump on intake side I hear no vacuum. The guage is on the discharge side. The seals on the pump nose do not look frayed or damaged. The pump is not leaking water in any of the joints. The pipes on discharge and well side do not appear to be leaking.

ANSWER : My friend, please boil your question down. Your title has to do with riding mowers but the leaking, bladder, impeller, air bubbles, pressure tank, check valve comments seem to be migrating toward a pump of some kind – well? spa? pool? irrigation?

Briefly, any system that involves a water source, a water moving device, water storage device and ultimate useage is subject to leaks … into the system and out of the system. If this is a well and you have air in your system, your pump may be sucking air at the well or any loose connection between the tip of the pipe and the inlet to the pump. Your bladder could have failed but from what I can get from your comments, this is not the case. On the pressure side, neither air nor water will leak in … only out.

Please recheck all connections. Make sure your check valve is installed correctly and not leaking. The check valve assists the foot valve, which may have failed.

I am more inclined to think your well may be at the end of its useful life. To prove or disprove, you could have a plumber put a vacuum gage on your pump. He or she can answer this question is about 90 seconds based on this test. Expect to pay for one hour of time, which will be less than the time you have already invested in your project.

The noise sounds like a much louder humming sound; Temperatures were well below freezing here last night
ANSWER : I’m not sure what your humming is much louder than. But if you had a freeze your pump may have froze and you will need to ck for leaks after thawing. You could have cracked your pump or hurt the seals. After you check for this, you can check for a weak start capacitor in your motor, as the cold can affect these also. Good luck.

My pump is making a loud humming noise and when I turned it on would not come on , just hummed. Tried again later and eventually came on but still making noise. Do I need a new pump. It is about 5 years old. I have an indoor pool so not in the cold weather
ANSWER : My Sunterra pump made that noise and I had a problem getting it to come back on after unpluggin to clean pre-filter each time. It was not long after that the plastic impeller sheared in pieces (the pump was only 1 year old and thankfully under warranty) My guess is that this is fixing to happen to yours as well. You are lucky to get 5 years. There was no reason for mine to come aparts. Uunterra sent me a replacement pump which had been slightly re-designed of the same 2000 gl size and the new one jsut did the same thing (only 2 1/2 months old) I called them again which in the meantime will mean my pond going witout filtration once again. I am getting very upset about this and will be looking for a good deal on a different brand pump.

In 2006 I purchased an automatic transmission Craftsman lawn tractor, model YS 4500 / 917.276641. A couple of months ago, it started not going forward or back well. It would eventually work, when I did everything just right, but slowly. After another use or two, it quit moving at all. (It starts with no problem, and the blades work fine.) I looked at it until I noticed that the ground drive belt seemed crazy loose and while the pulleys were turning, it wasn’t. Thinking that didn’t seem right, I went to my local Sears and the salesman agreed it sounded like a loose belt, so he ordered me a Hydro Ground Drive Belt, part no. 140218. When it arrived, I noticed it’s white instead of black like my old one, and seems 6+” shorter. I attempted to install it per the instructions in my manual. I get it around the mandrel and idler pulleys with no problem, but there’s no way I’m getting it around the clutch pulley. In my further research, I’m wondering if it would more likely be the motion belt, anyway, if it’s a belt issue at all. I would appreciate any help/insight. Thank you!
