Why Is the Miele T1 TCA230WP Drum No Longer Spinning?
When the motor of the Miele TCA230WP dryer starts normally and makes its typical background noise, but the Honeycomb drum remains stationary, the diagnosis almost always points to a break in the mechanical drive train.
The main causes are listed by probability:
- Snapping or slipping off of the Poly-V belt (85%): The elastic EPDM rubber belt undergoes continuous thermal cycles (40-65°C) and heavy strain due to wet laundry weight. Over time, the internal polyester fibers give way, causing a transverse break. The motor shaft then spins freely without driving the drum.
- Seizure or melting of the belt tensioner pulley / idler pulley (10%): If lint or dried-out grease seizes the idler pulley bearing, continuous rubbing melts the pulley plastic or snaps the belt due to friction.
- Wear of support rollers or drum friction (3%): The Teflon/polyurethane rollers supporting the drum deform or the rear bushing loses tolerance, excessively increasing the load required on the belt.
- Damage to the motor shaft splines (2%): Wear of the drive grooves on the motor shaft.
Often happens when... drying very heavy, unbalanced loads regularly (water-soaked duvets or jeans): high starting torque causes the belt to slip on a lint-clogged idler pulley, snapping it cleanly.
How to Independently Check the Cause of the Fault?
Before any troubleshooting, disconnect the plug from the 230V power outlet.
- Manual rotation test: With the machine turned off, open the door and rotate the drum by hand. If it spins completely freely, smoothly, and without resisting, the belt is broken 99% of the time.
- Quick top inspection: By removing the top panel screws with a Torx screwdriver, you can directly see whether the belt is still wrapped around the outer circumference of the drum.
- Basement debris analysis: Black rubber dust or fraying in the lower compartment indicates a seized belt tensioner and subsequent drive wear.

Is It Worth Repairing or Replacing the Dryer?
Repairing the Miele T1 TCA230WP is almost always cost-effective. It is a high-end appliance with high residual value, and the fault is mostly mechanical and inexpensive to fix.
- DIY (experienced user): Spare parts cost (belt + tensioner pulley) between €25 and €45.
- Specialized technician: Estimated cost between €90 and €150 (labor and parts included).
- Appliance replacement: Not recommended; purchasing an equivalent model would cost over €700–€900.
Which Checks Should the Technician Perform?
If the evaluation is handed over to a professional, the service sheet should include:
- [ ] Check the integrity and residual tension of the Poly-V belt.
- [ ] Manual rotation test of the tensioner pulley bearing (checking for grinding noises or heat deformation).
- [ ] Check extension and tension of the tensioner spring assembly.
- [ ] Mechanical inspection of the front Teflon glide rollers and the rear bushing.
- [ ] Deep cleaning of accumulated lint in the scroll housing and around the motor shaft to prevent overheating.
Final operational decision:
If the manual drum rotation test offers no resistance -> replace the Poly-V belt and tensioner pulley; if the drum is mechanically jammed -> replace the support rollers.
