Features and appearance will vary throughout this manual
1. Load Dishwasher: For best dishwashing results, follow the loading guidelines found in the Loading section. No pre-rinsing of normal food soil is required. Scrape off hard soils, including bones, toothpicks, skins, and seeds. Remove leafy vegetables, meat trimmings, and excessive amounts of grease or oil.
2. Add Detergent: Add needed amount of detergent to the detergent dispenser. Use detergent such as Finish® Quantum® Automatic Dishwashing Detergent. See Dispensers section.
3. Add Rinse Agent: Add rinse agent such as Finish® Jet-Dry® Rinse Aid to the rinse agent dispenser. See Dispensers section. NOTE: The use of rinse aid can further enhance the dishwasher’s drying performance.
4. Select Cycle
| AutoSense (on some models) | This cycle automatically senses the soil level and adjusts the wash cycle accordingly. *Time range: 1 hour 50 minutes - 2 hours 5 minutes. |
| Heavy | This cycle is meant for heavily soiled dishes, cookware, pots, or pans with dried-on or baked-on soils. Everyday dishes are safe to be used in this cycle. *Time: 2 hours 30 minutes |
| Normal | This cycle is meant for daily, regular, or typical use to completely wash a full load of normally soiled dishes and is designed to conserve both water and energy. Normal was used to rate the energy efficiency of this dishwasher. *Time range: 1 hour 15 minutes - 1 hour 45 minutes. |
| 1 Hour | This cycle is for light to medium soiled dishes and takes about 1 hour. It is safe for china and crystal with no options selected. *Time: 50 minutes. |
| Rinse (on some models) | For rinsing partial loads that will be washed later. Do not use detergent. Detergent is not dispensed during the rinse cycle. *Time: 15 minutes. |
*Washing time only. Does not include drying time, Auto Hot Start, or options. NOTE: If the incoming water temperature is too low, the Auto Hot Start feature may add up to 11 minutes of additional time.
5. Select Options: The light by the selected pad will be lit to indicate which Option has been selected
| Wash Temp Boost (on some models) | This option increases the temperature to help clean heavily soiled dishes and will increase the cycle time by 20 to 50 minutes. Option may be turned On or Off during the wash cycle. This option will also improve dry performance on the Normal cycle. |
| Steam Sani (on some models) |
This option has several functions. Steam is introduced at the beginning of the cycle to help with heavily soiled and/or dried-on, bakedon soils and for sanitization of dishware along with improving dry performance by raising the water temperature in the final rinse. The cycle length will vary depending on the temperature of your inlet water. This option MUST be selected PRIOR to starting the cycle. Available with Heavy, AutoSense and Normal cycles. NOTE: This option is monitored for sanitization requirements. If the cycle is interrupted during or after the main wash portion or if the incoming water temperature is so low that adequate water heating cannot be achieved, the sanitizing conditions may not be met. In these cases, the Sanitized light will not illuminate at the end of the cycle. Utilizing this option will modify the cycle to meet the requirements of Section 6, NSF 184 for soil removal and sanitization efficacy. NOTE: NSF certified residential dishwashers are not intended for licensed food establishments |
| Heated Dry | This option can be selected by pressing the Dry button once to illuminate the Heated light. This setting will greatly improve your dry performance for daily, regular or typical dishes. The heated dry option will typically add 48 minutes to your cycle time. This option is not available with the Rinse cycle. NOTE: The use of rinse aid can further enhance the dishwasher’s drying performance. Heated Dry was selected to rate the energy efficiency of this dishwasher |
| Dry Boos | This option can be selected by pressing the Dry button twice to illuminate the Boost light. This option will add additional time to your heated dry option, further enhancing the dishwasher’s drying performance for difficult to dry items. NOTE: The use of rinse aid can further enhance the dishwasher’s drying performance. |
| Heated Dry Off | Shuts off the drying option. Dishes air dry naturally and energy is saved. Opening the door at the end of the cycle can improve drying performance. NOTE: The use of rinse aid can further enhance the dishwasher’s drying performance |
| Bottle Jets (on some models) | This option increases the time that the bottle jets are on and may add up to 23 minutes to the cycle time. Use this to wash difficult to clean, dishwasher safe baby bottles, sport bottles, tall coffee cups, etc. See use recommendations in the Loading section |
| Wash Zones (on some models) | Selecting either the Upper or Lower Wash Zones will target dishwashing of just one rack. This will shorten the cycle time and conserve energy. This option should be used when dishes are placed in only one rack. |
| Delay Hours (on some models) | Delays the start of a wash cycle up to 8 to 12 hours depending on model. Press Delay Hours, to select the number of hours, then press Start one time and close door to begin countdown. The cycle will start once allotted time has expired. |

The air gap is easy to clean.
| Problem | Possible Cause | What To Do |
| Start status indicator light flashing | The door was opened or the cycle was interrupted. | Press the Start pad once and close the door within 4 seconds to start the dishwasher. Press the Start pad a second time when the dishwasher is running only if you wish to cancel the cycle. |
| Dishwasher BEEPS once every minute (on some models) | 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. | Press Start and close the door. |
| Beeping at the end of the cycle (on some models) | This is normal. Dishwasher will beep twice at the end of the cycle. | To turn off the double beep indicator (or re-activate it if it was previously turned off), press the Heated Dry pad 5 times within 3 seconds. A triple beep will sound to indicate the end-of-cycle beep option has been turned on or off. |
| Dishes and flatware not clean | Ultra-Fine Filter or Fine Filter is clogged | See the Care and Cleaning section. |
| Low inlet water temperature | 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 Wash Temp Boost if available. | |
| Water pressure is temporarily low | 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 | |
| Air gap or disposer clogged | Clean the air gap or flush the dispose | |
| High drain loop or air gap not installed | Refer to the Installation Instructions for proper drain line installation. | |
| Improper rack loading | Make sure large dishware does not block the detergent dispenser or the wash arms. See the Loading section | |
| Poor performing detergent | Use a highly rated detergent such as Finish® Quantum® Automatic Dishwashing Detergent. | |
| Spots and filming on glasses and flatware | Extremely hard water | Use rinse agents such as Finish® Jet-Dry® Rinse Aid to prevent spots and prevent new film build-up. If water is extremely hard, a softener may be required. |
| Low inlet water temperature | Make sure water temperature is at least 120°F (49°C). | |
| Overloading or improper loading of the dishwasher | Load dishwasher as shown in the Loading section. | |
| Old or damp powder detergent | Make sure detergent is fresh. Use a highly rated detergent such as Finish® Quantum® Automatic Dishwashing Detergent. | |
| Rinse agent dispenser empty | Refill with rinse agent such as Finish® Jet-Dry® Rinse Aid. | |
| Too little or low performing detergent | Make sure you use the proper amount of highly rated detergent. | |
| Cloudiness on glassware | Combination of soft water and too much 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. |
| Low performing phosphatefree detergent | See A white film on glassware, dishware and the interior in this TROUBLESHOOTING section. | |
| Water temperature entering the dishwasher exceeds 150°F (66°C) | This could be etching. Lower the water heater temperature. | |
| Suds in the tub | Wrong detergent |
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. |
| Rinse agent was spilled | Always wipe up rinse agent spills immediately. | |
| Black or gray marks on dishes | Aluminum utensils have rubbed against dishes | Remove marks with a mild, abrasive cleaner. |
| Dishes don’t dry |
Low inlet water temperature |
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 |
| Rinse agent dispenser is empty | Check the rinse agent dispenser and fill as required. | |
| Additional drying time is needed | 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. | |
| Cycle selection | If using Light cycle which uses lower water temperature and thus limited dry performance, switch to a different cycle. | |
| Cycle completion | Allow cycles to fully complete. See Long cycle times in this Troubleshooting Tips section | |
| Long cycle times | Dishwasher washes by alternating mid and lower spray arms | Longer cycles are normal. For best wash and dry performance, let cycle complete. |
| Soil level | 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. | |
| Control panel responded to inputs but dishwasher never filled with water | Door may not be completely closed | Make sure the door is firmly closed. |
| Water valve may be turned off | Make sure water valve (usually located under the sink) is turned on. | |
| Flood float may be stuck | Remove Ultra-Fine filter and lightly tap the piece under the ultra fine filter that looks like a dome. Replace the filter. | |
| Stained tub interior | Some tomato-based foods can cause reddish stains | Use of the Steam Sani cycle (on some models) after adding the dish to the load can decrease the level of staining. |
| Tea or coffee stains |
Remove the stain by hand, using a solution of 1/2 cup bleach and 3 cups warm water. NOTE: Do not use bleach on stainless steel inner door. CAUTION: Before cleaning interior, wait at least 20 minutes after a cycle for the heating elements to cool down. Failure to do so can result in burns |
|
| An overall yellow or brown film can be caused by iron deposits in water | A special filter in the water supply line is the only way to correct this problem. Contact a water softener company | |
| White film on inside surface— hard water minerals | GE Appliances recommends Finish® Jet-Dry® Rinse Aid to help prevent hard water mineral deposits from forming. Run dishwasher with citric acid to remove mineral deposits. Citric acid (Part number: WD35X151) can be ordered through GE Appliances Parts. See back cover for ordering information. Alternatively, purchase Finish® Dishwasher Cleaner and follow the directions on the label. | |
| Dishwasher won’t run | Fuse is blown or circuit breaker is tripped | Replace fuse or reset circuit breaker. Remove any other appliances from the circuit. |
| Power is turned off | In some installations, the power to the dishwasher is provided through a wall switch, often located next to the disposer switch. Make sure it is on. | |
| Control panel is locked | Unlock control panel. See the Getting started section | |
| Control panel lights go off when you’re setting controls | Time too long between touching of selected buttons | Each pad must be touched within 30 seconds of the others. To relight, touch any pad again or open the door and unlock (top control). |
| Water standing in the bottom of the tub | Air gap is clogged | Clean the air gap. See the Care and Cleaning section. |
| High drain loop or air gap not installed | Refer to the Installation Instructions for proper drain line installation. | |
| Water won’t pump out of the tub | Drain is clogged |
If you have an air gap, clean it. See the Care and Cleaning section. If the dishwasher drains into a disposer, run disposer clear. Check to see if your kitchen sink is draining well. If not, you may need a plumber. |
| Steam | This is normal | Warm, moist air comes through the vent during drying and when water is being pumped out. This is necessary for drying. |
| Sanitized light does not illuminate at the end of the cycle |
The door was opened and the cycle was interrupted during final rinse |
Warm, moist air comes through the vent during drying and when water is being pumped out. This is necessary for drying. |
| The incoming water temperature was too low | Do not interrupt the cycle by opening the door during the wash cycle. | |
| Noise | Normal operating sounds: Beeping at the end of the cycle (on some models) Detergent cup opening Water entering dishwasher Motor stops and starts at various times during cycle Spray arms start and stop at various times Drain pump sounds during pump out Drain pump starts and stops several times during each drain | These are all normal. No action is required. |
| Rattling dishes when the spray arm rotates | Make sure dishes are properly loaded. See the Loading section. | |
| Rattling silverware against door during wash | Tall utensils may be placed in the upper rack to avoid bumping against inner door during wash cycle. | |
| A white film on glassware, dishware and the interior | This problem is likely caused by a low quality phosphate-free dishwasher detergent | To remove the white film, run your dishes through a dishwasher cycle with citric acid. Use a WD35X151 citric acid kit found online. Otherwise, use Finish® Dishwasher Cleaner found at your local grocery store. Pour the citric acid in the detergent cup and close the cover. Place the filmed but otherwise clean glassware and dishware in the dishwasher. Leave silverware and other metal items out of the dishwasher. Turn the dishwasher on and let it run through a complete cycle without detergent. The glassware, dishware, and dishwasher should come out film free. Alternatively, a vinegar rinse may be used. Pour 1 cup of vinegar into dishwasher just after the detergent cup opens and let the dishwasher complete its cycle. This may be repeated several times a year as needed. The use of a rinse agent such as Finish® Jet-Dry® Rinse Aid may help minimize a repeat build up of film. Also, the use of a highly rated detergent such as Finish® Quantum® Automatic Dishwashing Detergent will help prevent film build-up |
