Question about Astra Mega II Espresso Machine

1 Answer

Whistling sound We have an Astra Mega II which has been working wonderfully for the past few months, but it has started whistling after five minutes of being on. It is annoying to the point that we can't use the machine anymore but being in a restaurant we kinda need it. It is coming from inside of the machine but I can't tell where. Any ideas?

The Astras have a vacuum relief valve, usually located on the boiler top. It looks sort of like a cap, with a pin or rod sticking up out of the middle, possibly with a ring through the end. While the machine is cold, you might try working that back and forth to see if it is stuck or not. If it is stuck, get it replaced.

2009 elantra SE, whistling sound this morning after a rainy night when i turned the key to start, it had delay for few sec and long whistling noise then started!

What you heard was probaly the drive belt, if it stopped after a few seconds, take a glss of water and pour on belt while running and see if it does it while pouring the water, this also works to tell if you have a bad belt or idler pulleys, if the squealing goes away its a belt if it keeps squealing its the idler. If its an actual whistle, before it starts, who knows......

It sounds that the horizontal output section circuit to your TV is to be checked. It is really a skilled work. Contact any service technician.

You might check the pulleys that the serpentine belt runs on. Make sure all are free wheeling and not loose or rough or make noise. You would need to remove the belt to check them.

Clicking sound near cambelt

It might be the idler pulley or automatic tensioner. When either one dries up, the bearing wears out and starts causing whistling or whining noises, might need replacing. Try replacing the cheapest one, the idler pulley to see if it stops. If not, it might be your belt tensioner.

Shower head is making high pitched whistling nois

The holes are probably clogged from hard water. Take the whole head assembly and dip it in a bucket of CLR for an hour or so. Then rinse off and give that a try. If your cheap, you can use a bucket of white vinegar and a little bit o water, but the smell is most disagreeable.

If it started after the brakes where changed it might be a problem with installation (maybe brake wear indicators [metal tabs to allert when brake pads are low]) or could just have a pebble stuck inbetween pad and disc. sometimes if the pad /disc wears unevenly, one or the other will develop a lip and this may cause your whistling sound.

Loud whistling sound on 1999 GMC Suburban

It sounds like your Idler pully bearing or your tensioner bearing. Regardless change them both and the surpentine belt too. The sound is letting you know that the bearinf is bad and will fail soon. Good luck
