GE GTW840CPNDG 5.2 cu ft Smart Top Load with SmartDispense MECH-NOISE Error Fix: Grinding or Squealing Noise During Agitation

A loud grinding, squealing, or clunking noise occurs during the wash or spin cycle — the drive block (a small square plastic piece on top of the transmission shaft that the agitator sits on) can wear round, causing the agitator to slip and make noise; the transmission itself can fail, producing grinding noises during agitation; on some models, the neutral drain assembly (transmission brake) wears out causing noise during transitions between cycles
