Loud bang, smell of burning

Manually turn the motor and drum and listen for the noise, if so the motor bearings, the drum agitator shaft and fittings must be checked. Also the suspensions which include the shock absorbers and springs, the body clamps must be checked to be in correct alignment and not changed in position. Tightening of the mounting is also very important. Finally in most cases a drop of OIL or smear of grease on the moving parts cane solve most issues.

The same happened to our Beko DCU8230 last week still under 1 year warranty, loud bang, burning smell and trip switch flipped. Beko Engineer who called said mains suppressor capacitor had blown.

Hope this helped Tim

It sounds like you your dryer may have a bad Blower Wheel, which is causing the banging noise that you are hearing (especially if the banging noise continues for a few sections after you turn your dryer off).

Hope this is helpful.

Open the dryer door (right after the breaker trips) and check for a burned smell. If it smells in the dryer, you probably have a direct short in the dryer wiring. Check for a burn smell at the wall socket. There may be a short in the socket itself, but not likely unless a mouse is lying across the contacts in the wall.
If everything checks ok replace the circuit breaker if this is an older home. Circuit breakers weaken after years of use. A 30 amp circuit breaker will trip at a much lower amperage after a period of years especially if it has tripped often.

I have the same dryer, with the dryer empty open the door and try to push the basket up, if it has lots of play in it then you should check the "bearing drum" which is attached to the front panel. this machine doesnt have bearing on the back of the drum. it rides on plastic sleaves called slide drum. they are on the inside of the front dryer panel. only 4 screws to remove and check
