The dishwasher might not be getting water due to several reasons like closed water supply, clogged parts, or electrical issues.

1. Check if the water supply is turned on.
2. Inspect the water inlet valve for voltage and any defects.
3. Clean the water valve inlet screen and check for blockages.
4. Examine the water fill line for any kinks.
5. Ensure the drain hose is installed correctly to prevent water siphoning out.
6. Test the door latch switches for continuity.
7. Check the float assembly for obstructions and test the float switch.
8. For electronic models, run the diagnostic test mode.
9. Look for loose or burned wires, and check the float assembly again.

This issue could stem from inadequate water pressure or valve issues.

1. Confirm water pressure is between 15 and 120 psi.
2. Test water volume by filling a quart container in less than seven seconds.
3. Clean the water valve inlet screen.
4. For portable models, check the aerating snap adapter.
5. Test the timer and electronic control for proper functioning.
6. Inspect the float switch and adjust or replace if needed.
7. Recheck the water fill line for any kinks.
8. Refer to the service manual for the correct water level in the tub after the fill cycle.

This can be due to issues with spray arms, loading, or temperature.

1. Check if the upper spray arm is moving and not clogged.
2. Inspect the arm for splits and ensure dishes are loaded evenly.
3. Clean the filter assembly and check the lower impeller.
4. Confirm water temperature is at 140°F.
5. Ensure proper detergent usage and check the dispenser.
6. On some models, inspect filters for blockages.

Similar reasons to the upper rack, including spray arm or loading issues.

1. Ensure the lower spray arm is moving and not obstructed.
2. Check for any binding of the spray arm on the housing.
3. Verify water temperature and detergent usage.
4. Ensure dishes are loaded correctly.
5. Check filters on certain models for blockages.

This could be due to low water temperature or malfunctioning components.

1. Verify water supply temperature.
2. Check the heater, wiring, timer, or electronic control board.
3. Ensure correct voltage to the heater and inspect the heater fan assembly.
4. Check the use of rinse aid and the level.
5. Inspect the door baffle and vent system.

Leaks can occur due to faulty seals, overfilling, or spray arm issues.

1. Inspect and clean the spray arm.
2. Check the tub gasket and corner gaskets.
3. Inspect the vent baffle gasket and corner gasket.
4. Ensure no overfilling of water.
5. Check door closure and gasket clips.
6. Observe the user loading the dishwasher for correct method.
7. Verify proper drainage and dishwasher leveling.
8. Inspect the door liner and wetting agent dispenser.

Leaks here might be due to damage or loose fittings.

1. Check the side inlet tube and pump assembly for leaks.
2. Inspect the motor seals.
3. Look for any damage or rust in the tub.
4. Ensure tightness of the water inlet port and heater element nuts.
5. Tighten all screws in the motor, pump assembly, and upper rack.

Could be due to electrical issues or mechanical faults.

1. Ensure there's voltage to the timer motor or control board.
2. Check if the timer cams are rotating.
3. Verify correct wiring and check for a jammed timer.
4. Test the selector switch and run diagnostic mode.

Could be due to mechanical or electrical faults.

1. For a cup that won't open: Check voltage to the solenoid, inspect for binding, and ensure no dishes block the door.
2. For a cup that won't close: Inspect the actuator, cams, and ensure proper adjustment.

Electrical problems or physical obstructions can cause motor issues.

1. For a non-operating motor: Check continuity at the windings, voltage to the motor, and for obstructions.
2. For a motor going into overload: Check the relay, pump assembly, voltage, polarity, and motor windings. Test the run capacitor if present.

Misalignment or incorrect installation.

1. Check if the tub is square and correct installation issues.

Power supply issues or faulty controls might be the reason.

1. Check electrical connections, door switch, selector switch, timer, and control board.
2. Inspect wiring on the timer and switches.
