Hotpoint Tumble Dryer Tension Pulley
The spring-loaded pulley that keeps the drive belt tight against the motor.
Signs it has failed
- A squealing or chirping noise from the front of the dryer
- A thumping noise with each turn
- A belt that keeps slipping off or wearing quickly
- A pulley that wobbles or no longer spins freely
Check before you buy
- With the belt off, spin the pulley by hand and feel for roughness or play
- Check the spring arm moves freely and holds tension
- Replace it when you fit a new belt if it is worn
What replacing it fixes: if the signs above match your tumble dryer and the checks point to this part, fitting a new one should clear those faults. If the symptoms continue, the cause is elsewhere (a control board, a sensor or a blocked vent or hose).
How to replace it
- Unplug the dryer and open the cabinet for belt access
- Release the belt tension and remove the belt
- Unscrew or unclip the old idler pulley assembly
- Fit the new one and refit the belt
- Close up and test
