What To Do
Use only automatic dishwasher detergents to avoid sudsing.
Finish Quantum Automatic Dishwashing Detergent
® ®
has been approved for use in all GE Appliances
dishwashers.
To remove suds from the tub, open the dishwasher and
let suds dissipate. Pump out water by pressing Start and
close the door. Wait 30 seconds. Open the door, press
and hold Start for 3 seconds, and close the door. Repeat
if necessary.
Always wipe up rinse agent spills immediately.
Reposition the dishes, so the water from the lower spray
arm can flush the detergent cup. See the Loading section.
Reposition dishware that may be keeping the dispenser
cup door from opening. See the Loading section.
Remove marks with a mild, abrasive cleaner.
Make sure inlet water temperature is at least 120°F.
Select Heated Dry or Dry Boost.
Use Wash Temp Boost.
Select a higher cycle, such as Steam Sani or Heavy.
Check the rinse agent dispenser and fill as required.
Leave door closed after the Clean light appears to allow
the fan to run an additional 90 minutes (on some models).
Note: If you open the door, this fan extension will be cancelled.
If using Light cycle which uses lower water temperature
and thus limited dry performance, switch to a different cycle.
Allow cycles to fully complete. See Long cycle times in
this Troubleshooting Tips section
Longer cycles are normal. For best wash and dry
performance, let cycle complete.
The turbidity sensor senses how much soil is on the
dishes. Heavy soiled dish loads will add more time to
the cycle. This is normal function. For best wash and dry
performance, allow cycle to complete.
Make sure the door is firmly closed.
Make sure water valve (usually located under the sink) is
turned on.
Remove the Ultra-Fine Filter assembly and lightly tap the
piece under the ultra fine filter assembly that looks like a
dome. Replace the filter.
