Samsung Dishwasher: not rotating
What is this symptom?
Is your Samsung dishwasher not rotating the spray arms? This issue can lead to inadequate cleaning, as the arms may remain stationary or bind during cycles. Common causes include blockages from debris, improperly loaded dishes, or worn components, impacting water flow and performance. Understanding these factors can help you troubleshoot effectively.
Important Tips for Samsung Models
- Stationary ‘Waterwall’ style arm issues (unique to Samsung) can involve specific water distribution systems obstructed or malfunctioning
Possible Causes
Spray arm blockage with debris
How to Identify: Arms are visibly jammed, debris in nozzles or arm bearings; water pressure seems weak at the jets
Part: Upper or lower spray arm nozzles and rotation posts
Obstruction from improperly loaded dishes
How to Identify: Items (utensils, tall dishes physically touching arms and preventing spin; repositioning allows free movement
Part: Spray arms and dish racks
Worn or damaged spray arm support/shaft
How to Identify: Arm spins loosely by hand or wobbles, doesn’t engage properly with rotation post; cleaning doesn’t restore free movement
Part: Spray arm shaft/support, clips or bearings
Water flow insufficiency (pump blockage, filter clog)
How to Identify: Overall weak spray from nozzles, diagnostic shows water not reaching arms with enough pressure; cleaning filter improves flow but may not fix if pump issue
Part: Dishwasher filter, circulation pump
Electronic control / motor assembly fault
How to Identify: No water circulation or intermittent operation; error codes present; other symptoms like failure to start cycle
Part: Control board or pump motor assembly
DIY Solutions

- Debris or food particles blocking the spray arms
- Faulty motor or pump preventing the spray arms from rotating
User Suggested Solutions
-
Inspect and secure the plastic pieces. Remove the spray arms and check the plastic connectors for damage. Use zip ties to secure them if necessary, ensuring they do not obstruct the rotation of the arms.
-
Clean the spray arms. Remove them from the dishwasher and check for clogs. Rinse them under warm water and use a soft brush to clean out any debris.
-
Test the motor and pump. If the spray arms are still not rotating after securing the plastic pieces and cleaning, check the motor and pump for functionality. This may require a multimeter to test electrical continuity.
