Transit Bolts Left in Place
What it is
Front-loading washers ship with 3–4 large transit bolts that lock the drum to the cabinet for transport. They must be removed before first use. In Khobar's rental market, washers are moved between apartments frequently — and transit bolts are often reinstalled for the move and never removed again.
Symptom
Violent vibration from the very first use. The washer "walks" during spin. Loud banging. Possible drum damage.
The fix: The transit bolts are locking the drum. Remove them and the vibration stops immediately.

"Suspension rebuild" (800–1,500) or unnecessary "new washer" (1,500–3,000)
