Read the manual, have it repaired. There is a switch inside or electronics, like an alarm call that plays on every hour. Try removing batteries for 5 minutes to reset.
Sounds like a bearing problem. The gears are held in place by roller bearings, and they sometimes pack up. Working the machine with a bad bearing eventually grinds up the steel balls or rollers that the flanges roll on, and the bearing collapses completely. The bearing itself will announce its demise with a grinding sound, and worst case scenario the bearing is so far gone that the gears are running out of true with respect to one another, and this could be the grinding you are hearing.
You should call your vendor for service. Especially if this equipment is on loan from them.
*** The following is for information only. Equipment should be serviced by a qualified tech. ****
* Bunn.com has a free download of their manuals.
* Check the parts diagram if you have assembled everything properly. Often people forget the 'button' (looks like a nickel with a dent in it.)
* Perform the following adjustments WITHOUT beans as they will prevent you from hearing to any problems.
* Opening the burrs too wide (turning too far counter clockwise) will have the plate scraping the cover and you get metal flaking along with a teeth chattering/grinding sound. Turn the adjustment several times CLOCK-WISE and try again. If you still get grinding then take everything apart and check for objects in the burr area then reassemble according to the parts diagram. Make sure you have the correct model and diagram.
* Closing the burrs too tight (Clock-wise) will have the burrs touch and lock up together. There is another loud grinding sound but not as bad as hitting the case. Though back it off fast as you will ruin the plates if they over heat.
* Note; Once you get things in range. (No loud metal chatter or grinding sounds. Just a nice hum and whirling sound. The you will need to calibrate the plate. Go ahead and add a few table spoons of beans. Keep it to a very small amount as you will probably end up dumping them (a waste). I use 'expired' or old beans for this.
* Calibration is done by grinding a few beans at a time. You must clear the beans completely before adjusting to the next setting. Keep turning the dial to the fine setting. Keep grinding small doses until you get to the level of grind that matches the finest setting on the dial (usually Turkish grind which is almost a powder.) Adjust this back (Larger) a bit as most people end up burning the beans at this fine a grind. It also takes forever to grind a whole bag, even with only 10 oz of beans. Lock down the adjustment screw once your satisfied with the grind matching the dial.
* Note; If you find the motor trips out often then back off the grinder for a larger (course) grind.
*Finally check with your vendor if your still having problems.
hello, this is cause for concern, and may or may not be serious and safety related. if possible, the vehicle should be parked on level, solid ground and the rear wheel that is suspect should be lifted about 1 to 2 inches off the ground. observe all the appropriate safety precautions associated with this procedure. be careful not to place or have any of your body parts under the vehicle at any time. spin the wheel by hand and observe. next you might grab the tire firmly at its 3 o'clock and 9 o'clock positions and attemp to shake or rock the wheel, of course not to such degree that might dislodge the car from the jack. repeat the shake test with hands at 6 and 12 o'clock. what is observed from these three activities will determine the next steps.
the possible causes of the sound are many, including.....
loosened caliper bracket failed rear brake pad hardware, allowing a brake pad to contact the rotor when brakes are not applied sticking or siezed brake caliper distorted backing plate rubbing on the rotor failing wheel bearing failing rear lower ball joint, causing wheel to rotate out of its specified position
..... and of course noises heard while driving can be tricky, the noise may be coming from somewhere else although it sounds like it is from there.
if self jacking and checking is not possible, then a reliable mechanic must be visited and it is to your advantage if you make yourself present during a test drive and then removal of the wheel, first to have the noise observed and verified by the technician, and then to observe firsthand with he or she the initial findings. you want to avoid the possibility of receiving a phone call from the repair facility and hearing " it needs everything ".
The constant beeping means that something is out of place - make sure the charcoal water filter holder is in place, even if there are no filters inside. Make sure the grind chamber and all parts are in place. Make sure the filter basket is in place, and that the door is closed. Finally, make sure the lid of the coffee maker tiself is shut and that the lid of the craffe is firmly in place. If everything is in place, it should stop beeping. Turn the coffeemaker off, and then on after all of this is done.
In my humble opinion, a dryer making a grinding noise is worth repairing. Possible Problems:
Worn Drum Rollers (Very Likely): More of a thumping / grinding sound. Replacing drum roller supports is considered to be a routine "normal ware & tear" repair with parts costing about $15 - $20 or so. Its' kinda like a tune-up for a vehicle. The rollers can be located in a couple places, but are typically located on the inside rear of the drum; upon dis-assembling the dryer.
Broken/Loose Blower Fan Wheel (Likely): The blower wheel can become loose or brake off the motor shaft and can make a "rumbling / grinding sound and can run about $15 - $25 for the part. The degree is difficulty when repairing a little high, but is commonly performed.
* Note: Removing and threading the blower wheel is reverse to prevent the fan blower from natually spinning/coming-off "Righty loosey, lefty tighty"
Unfortunately Bose will not release their schematics or parts lists, effectively giving them a monopoly on repair of these sets. Before you spend
the big bucks on repair or a Bose "upgrade", you might want to check out the new HD radios.
Better sound and MUCH lower prices than the Bose.
