Bosch Dishwasher: not spinning
What is this symptom?
Is your Bosch dishwasher not spinning? This common issue often leads to inadequate cleaning as the spray arms fail to rotate, leaving food debris on your dishes. The problem may stem from blocked spray arms, a faulty control board, or even physical damage. Address this promptly to restore optimal performance.
