Avanti Dryer: Abnormal Noise or Vibration
Dryer noise is diagnosed by whether it follows the drum or the motor: a thump once per revolution is the drum support, a continuous squeal is a bearing or an idler, and a rattle that changes with the load is usually something in a pocket. The ordering below is what makes this page worth reading on an Avanti dryer. This is a compact cabinet with very little air around its condenser, so clearance and ventilation outrank component failure. What ranks first here is something you can correct yourself in under an hour, which is the reason to work down the list in order rather than book a visit straight away.
What you are actually seeing
- Check your symptom against this list first.
- A thump or bump once per drum revolution.
- A continuous squeal or screech that rises with the drum.
- A rattle or clatter that changes when the load is rearranged.
- A scraping from one side of the drum.
- Not this fault: If the drum does not turn at all and the motor hums, stop the machine — that is a belt or motor fault, not a noise complaint.
Causes, in the order worth checking
- Ranked by how often each turns out to be the answer on an Avanti dryer.
- Machine not level or in contact with the wall or the washer beside it — Why: A dryer that rocks or touches a neighbouring machine transmits every vibration into the room. It is common in a stacked or side-by-side laundry. Compact units are put wherever they fit — alcoves, closets, garages — so installation faults are over-represented in this class.
- Coins, buttons or a zip pull loose in the drum or the lint housing — Why: It is by far the most common cause, it makes a clatter that changes with the load, and it is fixed by emptying pockets. Objects that reach the blower housing rattle continuously.
- Drum support rollers or slides worn — Why: The drum runs on rollers or plastic slides, and worn ones produce a thump once per revolution that grows over months. It is the most common genuine wear item in a dryer.
- Idler pulley or belt worn — Why: The idler tensions the belt and its bearing is a consumable. When it goes it squeals continuously and rises with the drum speed.
What to check, and in what order
- Each step eliminates the largest branch of the tree for the least effort.
- Run the dryer empty for a minute and listen. — Why: It separates load noise from machine noise immediately and costs nothing.
- Turn the drum by hand with the machine unplugged and listen for something loose. — Why: It catches the foreign-object cause, which is the most common one, without any tools.
- Check the machine is level and not touching the washer or the wall. — Why: It is the second most common cause and it is corrected with a spanner.
Checks you can safely do yourself
- Stop at the first step that would put a meter on live terminals.
- Run the machine empty for one minute and note whether the noise is still there. — Tools: None
About 10 min
- Unplug the machine, remove the lint filter and turn the drum slowly by hand, listening for anything loose. — Tools: Torch
About 15 min
- Vacuum the lint housing beneath the filter and check for coins and buttons collected there. — Tools: Vacuum with crevice tool, torch
About 20 min
- Put a spirit level on top of the machine, adjust the feet until it does not rock, and check it is not touching the washer or the wall. — Tools: Spirit level, adjustable spanner
About 25 min
Before you touch anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. — Id: unplug-before-service
Unplug the dryer or switch off its breaker before reaching into the drum, the lint housing or any panel; a capacitor in the drive circuit can hold a charge after the power is off. Lint is highly flammable, so never run a dryer with the lint filter removed and never leave a panel off to listen to it. If the noise came with any smell of burning, stop using the machine entirely.
Where the owner checks end
Call a technician when one of these is true, and not before.
When a thump occurs once per drum revolution with an empty drum, which points at the support rollers. When a continuous squeal rises with drum speed, which points at the idler or the belt. When a grinding is present with an empty drum and has worsened over months.

What this page does not cover
Links down: - [Common Avanti Dryer Problems](/blog/avanti-dryer-problems)
This page is generalized: it covers the Avanti dryer line as a whole and does not narrow to a family, a model number or a serial range. The use-and-care guide covers the owner-serviceable envelope; a full service manual is not generally published for these models, so diagnosis works from the symptom rather than from a published code chart. The overview at avanti-dryer-problems lists every problem class for this machine and routes down to the page for each; any family- or model-specific page that exists beneath this one is linked from there.
