Possible Cause
The door was opened or the
cycle was interrupted.
This is a reminder that your
dishwasher door has been left
open during operation. It will
continue beeping until you
press Start and close the door.
This is normal. Dishwasher will
beep at the end of the cycle.
Ultra-Fine Filter or Fine Filter is
clogged.
Low inlet water temperature.
Water pressure is temporarily
low.
Air gap or disposer clogged.
High drain loop or air gap not
installed.
Improper rack loading.
Poor performing detergent.
Extremely hard water.
Low inlet water temperature.
Overloading or improper
loading of the dishwasher.
Old or damp powder detergent.
Rinse agent dispenser empty.
Too little or low performing
detergent.
Combination of soft water and
too much detergent.
Low performing phosphate-free
detergent.
Water temperature entering the
dishwasher exceeds
150°F (66°C)
What To Do
Press the Start button once and close the door within
4 seconds to start the dishwasher. Press the Start button
a second time when the dishwasher is running only if you
wish to cancel the cycle.
Press Start and close the door.
See the Care and Cleaning section.
Make sure inlet water temperature is correct (see the
USING THE DISHWASHER section). Turn on the
hot water faucet nearest the dishwasher, let run until
the water temperature stops rising. Then start the
dishwasher and turn off the faucet. This ensures the
entering water is hot. Select Hi Temp if available.
Turn on a faucet. Is water coming out more slowly
than usual? If so, wait until pressure is normal before
using your dishwasher. Normal water pressure to the
dishwasher should be 20-120 psi.
Clean the air gap or flush the disposer.
Refer to the Installation Instructions for proper drain line
installation.
Make sure large dishware does not block the detergent
dispenser or the wash arms. See the Loading section.
Use a highly rated detergent such as Finish
Automatic Dishwashing Detergent.
Use rinse agents such as Finish
prevent spots and prevent new film build-up.
If water is extremely hard, a softener may be required.
Make sure water temperature is at least 120°F (49°C).
Load dishwasher as shown in the Loading section.
Make sure detergent is fresh. Use a highly rated
detergent such as Finish Quantum
®
Dishwashing Detergent.
Refill with rinse agent such as Finish
Aid.
Make sure you use the proper amount of highly rated
detergent.
This is called etching and is permanent. To prevent this
from happening, use less detergent if you have soft
water. Wash glassware in the shortest cycle that will get
it clean.
See A white film on glassware, dishware and the
interior in this TROUBLESHOOTING section.
This could be etching. Lower the water heater
temperature.
