🌀 Whirlpool washer displays FSE error (spin error)

🔧 Troubleshooting Steps

1. Check the drive belt — it should be tight enough to have 1/2 inch of deflection at the midpoint between pulleys. A loose belt causes the tub to not reach spin speed
   ✓ Expected: Belt tension correct (1/2 inch deflection)
2. Check the drive pulley and transmission coupling. If the belt is properly tensioned but the tub spins slowly, the transmission may be slipping
   ✓ Expected: Pulley and coupling intact, no play
3. Check the motor coupler (between motor and transmission). On Whirlpool top-loaders, the plastic coupler is a known failure point. If it's cracked or broken, the motor spins but the tub doesn't
   ✓ Expected: Coupler intact, not cracked or sheared
4. If the coupler is intact, check the transmission for internal wear. A worn transmission will make grinding noises and not maintain spin speed
   ✓ Expected: Transmission runs smooth, no grinding
