Amana Dishwasher: not cleaning properly
What is this symptom?
Is your Amana dishwasher leaving dishes dirty with food residue and film? This common issue can stem from clogged spray arms, dirty filters, or insufficient detergent. If your dishwasher isn't providing a thorough clean, it's essential to identify the root cause to restore its performance.
Important Tips for Amana Models
- Hard water/mineral buildup inside the dishwasher can specifically impact Amana spray arms and performance; Affresh or similar cleaners recommended by Amana.
- Upper rack position can block detergent dispenser from opening fully, leading to poor cleaning if rack not adjusted.
Possible Causes
Clogged or restricted spray arms
How to Identify: Dishes aren’t evenly cleaned, spray arms don’t spin freely, holes blocked by debris or mineral buildup
Part: Upper and lower spray arms
Clogged or dirty filters
How to Identify: Visible food debris on filter, standing water, dirty water recirculation, debris on dishes
Part: Dishwasher filter assembly
Insufficient detergent or incorrect detergent type

Part: Detergent dispenser and detergent choice
Incorrect wash cycle selection
How to Identify: Poor results on heavily soiled loads when using light/normal cycles

Mineral buildup / hard water deposits
How to Identify: White film, buildup in spray arm holes, reduced spray efficiency
Part: Internal dishwasher surfaces and components
Faulty water inlet valve
