Amana ADB1400AGB1 dishwasher Parts

In the Amana dishwasher model ADB1400AGB1, the most commonly replaced parts are the wash and drain components (pumps, hoses, inlet valve), heating and drying parts, and wear items like filters and rack hardware. These parts typically fail from clogs, hard-water buildup, leaks, or normal wear.

Most common dishwasher parts people replace

• Heating and drying: heating element, related wiring connections
• Water fill: water inlet valve
• Draining: drain pump, drain hose
• Washing performance: circulation pump, sump and motor assembly, filters
• Leaks and vibration: pump grommets, hose clamps
• Rack usability: rack stops, rack rollers, rack assemblies
• Controls and dispensing: electronic control board, detergent dispenser

Model ADB1400AGB1 examples (parts on this model)

These are examples of commonly replaced parts that match the ADB1400AGB1 parts list:

Symptom you notice	Likely part category	Example part for ADB1400AGB1
Dishes not drying, water not heating	Heating	Element assembly W10518394
Dishwasher not filling or fills slowly	Fill system	Dishwasher water inlet valve W11175771
Water left in tub	Drain system	Dishwasher drain pump W10876537
Poor cleaning, weak spray	Wash system	Sump/mtr asm W10888591
Grity residue, odors	Filtration	Dishwasher filter WPW10463906

Quick checks before you buy a part

• Clean the filter and check for debris in the sump area.
• Confirm the water supply valve under the sink is fully open.
• Check the drain hose routing for kinks and a proper high loop.
• Run hot water at the sink before starting the cycle.
• Use the correct detergent amount for your water hardness.

Why it matters

Dishwashers rely on the right water level, strong circulation, and proper heating to clean and dry. When a filter clogs, a pump weakens, or the heater fails, you will usually see poor cleaning, standing water, or wet dishes, even if the dishwasher still “runs.”

Most Amana dishwashers, including model ADB1400AGB1, use the same core components to fill, wash, heat, drain, and dry: a water inlet system, wash (circulation) system, filtration, heating, racks/spray arms, and electronic controls. For model-specific diagrams and locations, use the ADB1400AGB1 owner's manual.

Main dishwasher components (what they do)

• Water inlet valve: opens to let household water into the tub (common fill problems point here).
• Circulation pump and motor: pushes water through the spray arms for cleaning.
• Spray arms: spin and spray pressurized water to reach dishes.
• Filter system: traps food soil to protect the pump and improve cleaning.
• Heating element: heats wash water and helps with drying.
• Drain pump and drain hose: removes dirty water to the sink drain or disposer.
• Control board and user interface: runs cycles, monitors sensors, and powers loads.

Common ADB1400AGB1 parts that match these components

Component area	Example part for ADB1400AGB1	What you’ll notice when it fails
Heating	Element assembly W10518394	Poor drying, cooler wash water, longer heat portions
Filling	Dishwasher water inlet valve W11175771	No fill, slow fill, or stops early with little water
Draining	Dishwasher drain pump W10876537	Standing water, humming, or intermittent draining
Filtration	Dishwasher filter WPW10463906	Grit on dishes, odors, redepositing soil

Why it matters

Knowing which system is involved (fill, wash, heat, drain, or dry) helps you troubleshoot faster and buy the right replacement part the first time. For example, “not cleaning” usually points to filtration, spray, or circulation; “not draining” points to the drain path.

Quick troubleshooting pointers by symptom

• Won’t start: check door latch engagement and control settings; confirm power.
• Not cleaning: clean filters, verify spray arms spin freely, avoid overloading.
• Not drying: use rinse aid, select a heated dry option, check heating performance.
• Not draining: check the drain hose routing and air gap/disposer connection.

In the Amana dishwasher model ADB1400AGB1, the spinning part at the bottom is typically called the lower spray arm (also called the wash arm). It rotates during the wash to spray water upward through the lower rack and toward the upper rack.

What the lower spray arm does

The lower spray arm is a key part of the wash system; it distributes wash water and helps remove food soils.

• Spins from water pressure created by the circulation pump
• Sprays water through small jet holes to reach dishes
• Works with the filter and sump area to recirculate water
• Can clog with debris or hard-water scale and reduce cleaning
• Can crack or warp and cause poor wash coverage

Quick checks if it is not spinning or cleaning well

If dishes are coming out dirty, the spray arm is one of the first things we check.

• Make sure tall items are not blocking the arm under the lower rack
• Inspect spray holes; clear debris with a toothpick or soft brush
• Rinse and reinstall the filter if your model uses a removable filter
• Confirm the dishwasher is filling to the normal level
• Listen for strong wash action; weak sound can point to a circulation issue

Related parts that affect spray performance

If the spray arm is fine but wash pressure is weak, these parts are common suspects.

Symptom	Common area to check	Example part for ADB1400AGB1
Weak spray, poor cleaning	Heating and wash system performance	Element assembly W10518394
Not filling or fills slowly	Water supply into the tub	Dishwasher water inlet valve W11175771
Standing water after cycle	Drain system	Dishwasher drain pump W10876537

Why it matters

The lower spray arm is the main “water delivery” component in the tub. When it is blocked, loose, or damaged, you can get gritty residue, detergent left in the dispenser, and poor cleaning even on long cycles.
