My samsung dishwasher will not drain? What could be causing this problem. We checked the line and it is not plugged.


when you first start the dishwasher the first thing it will always do is drain, does it make the normal draining sounds or is it a low pitch humming noise? if its a low pitch humming something is stuck in the drain pump like a peice of chicken bone or glass, if it sounds normal then there is a blockage somewhere and 9/10 times its the little drain spiggot that the drain hose plugs onto under your sink, they often block up as the pipe diameter gets smaller there

Low pitched humming


When it makes the noise and you able to do this try turning to the right and to the left. If the noise changes or goes away than your on the right track with a bad wheel bearing.

Hi,If you are getting a black and white picture,color discoloration or a humming high pitch sound, it will be an issue with the color wheel.The color wheel is a rotating disc that spins at high rpm and its in charge of creating the colors on your set.Found it here:http://www.discount-merchant.com/Samsung-Replacement-Color-Wheel-HLS-HLT-Series-p/samsungcolor_wheel_bp96-01579a.htm You can replace it

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON

You need to take a closer look really, see if anything on the power supply board inside has melted, burned, popped, etc.

Works - but the sound has changed


Possibly, the "fault" was the buzzing in the first place! Buzzing is usually a cabinet vibration caused by magnetic fields from the "gubbins". If the buzzing should occur again, try pushing/ pulling/ poking the cabinet while the oven is running, you may find a position that causes the buzz to stop.
Another possibility is you previously had something else placed in close proximity to the oven.
If a rattling cabinet is the problem, either try to reposition something, or just ignore it!
