Clogged or cracked spray arms stop water coverage. This guide explains spray arm failure symptoms, causes, related error codes, quick fixes, and when replacement is needed.
Spray arms in a dishwasher spin and distribute water to clean dishes. When clogged, cracked, or stuck, cleaning suffers. Replacing faulty spray arms restores full water coverage and prevents cloudy, dirty loads. It is a simple but essential repair for consistent dishwashing performance.
Causes include mineral deposits clogging holes, food debris, detergent residue, or broken plastic from years of use. Heat stress may warp arms. Foreign objects jam rotation. Bearings and mounts can wear, letting arms fall or wobble.
Error codes: Bosch may show E24/E25 from circulation issues. LG and Samsung: OE/5E for poor spray. Whirlpool/Maytag: F9E1/F7E1 drainage or circulation codes. Frigidaire/Electrolux: i20/i30. Codes suggest poor cleaning and blocked spray arms.
Quick fixes: remove and rinse spray arms, poke holes clean with a toothpick, and soak in vinegar to clear mineral buildup. If arms are cracked or warped, replace with OEM parts. Ensure mounts click firmly. Run test wash with empty load to confirm spin.
Symptoms include dirty dishes, greasy residue, or spots after cycles. The spray arms may not spin, or water flow is weak. Visible cracks or blocked holes stop rotation. Loud knocking or rattling inside can indicate loose spray arms hitting racks.
Call a pro if spray arm replacement does not restore cleaning, or if pumps, circulation motors, or boards are failing. Techs can test water pressure, circulation, and confirm correct installation. Built‑in models may need pro removal for deeper access.
