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
