Amana Dishwasher: not washing
What is this symptom?
If your Amana dishwasher is running cycles but leaving dishes visibly dirty, it may be due to clogged spray arms, a dirty filter, or improper loading. Water might be filling, but ineffective spray action can lead to unsatisfactory cleaning results. Addressing these common issues can help restore your dishwasher's performance.
Important Tips for Amana Models
- Some Amana models may have multiple spray arm levels (upper/middle/lower) requiring careful inspection and cleaning
Possible Causes
Clogged or blocked spray arms
How to Identify: Dishes not getting hit by jets, spray arms don’t spin freely, visible debris in spray arm holes
Part: Spray arm (upper, lower, center)
Clogged or dirty filter
How to Identify: Food particles visible in filter, slow drainage, water pooling, dishes still dirty after cycle
Part: Dishwasher filter
Insufficient water circulation due to pump or circulation assembly issues
How to Identify: No strong water spray, pump humming but no water movement, dishes remain dirty
Part: Circulation pump/motor assembly
Improper loading and water coverage
How to Identify: Items blocking spray arms, overloading racks, dishes shielding each other from spray

Part: Detergent dispenser or detergent type
Low water temperature or supply issues
How to Identify: Cold water entering dishwasher, cycle completes too quickly without heating, films remain on dishes
