GE GSC470 Dishwasher
Frequently Asked Questions (10)
What is the minimum water temperature required for the GSC470 dishwasher to wash and dry dishes properly?
The entering water must be at least 120°F for good washing and drying results. To prevent dish damage, inlet water should not exceed 150°F. You can test your water temperature using a candy or meat thermometer at the nearest hot water faucet to the dishwasher. (Page 6)
What should I do if my dishwasher won't run at all?
A blown fuse or tripped circuit breaker in your home is the most likely cause. Replace the fuse or reset the circuit breaker, and remove any other appliances sharing the circuit. The dishwasher requires the full capacity of its circuit during operation. (Page 13)
How do I remove spots and film from glasses and flatware?
Remove all metal utensils, add no detergent, and select the POTSCRUBBER cycle. After 18 to 22 minutes when the dishwasher is in the main wash, open the door and pour 2 cups (500 ml) of white vinegar into the bottom, then close the door and allow the cycle to complete. If vinegar doesn't work, repeat using 1/4 cup (60 ml) of citric acid crystals instead. (Page 14)
Can I use a regular extension cord or adapter plug with the GSC470 dishwasher?
No, you must not use an extension cord or adapter plug with this appliance. The dishwasher must be supplied with 120V, 60Hz power and connected to an individual, properly grounded branch circuit protected by a 15 or 20 amp circuit breaker or time-delay fuse. Do not, under any circumstances, cut or remove the third grounding prong from the power cord. (Page 11)
How do I install the faucet adapter before using the dishwasher for the first time?
Remove the old aerator or trim ring from your faucet spout before attaching the adapter. If your faucet has external threads, insert the thinner of the two supplied washers into the faucet adapter and attach it; if your faucet has internal threads, insert both washers. If the adapter threads do not match your faucet, a local hardware or plumbing supply store can provide additional fittings. (Page 12)

How much detergent should I use for hard water versus soft water?
For soft water (0–3 grains hardness), use a minimum of 1 tablespoon in the main cup for POTSCRUBBER and Normal Wash cycles. For hard water (7–12 grains), fill both the main cup and open cup completely, noting that the filled main cup holds 3 tablespoons and the filled open cup holds 2 tablespoons. Water with 12 grains or more is extremely hard and a water softener is recommended, as lime can build up in the water valve and may cause flooding. (Page 7)
Which items should NOT be washed in the GSC470 dishwasher?
Iron, pewter, tin, and wood items should not be washed in the dishwasher, as they will rust, tarnish, or warp and crack. Non-dishware items such as electronic air cleaner filters, furnace filters, and paint brushes must also never be placed in the dishwasher, as they can damage it and cause discoloration or staining. Plastic items not marked 'dishwasher safe' should be tested or avoided. (Page 10)
How do I prepare my GSC470 dishwasher for winter storage in an unheated location?
Have a service technician remove fuses or trip circuit breakers to cut electrical power, then turn off the water supply and disconnect the water inlet line to drain it. The technician should also remove the water valve and blow on the small plastic outlet to remove water, then replace it, and remove the plug in the bottom of the rubber boot to drain it completely before replacing the plug. These steps prevent the machine from freezing during winter months. (Page 11)
What should I do if there are suds in the dishwasher tub?
Only use automatic dishwasher detergents, as sudsing detergents are not meant for dishwashers and can cause the unit to overflow. To remove existing suds, open the dishwasher and let the suds evaporate, then add 1 gallon of cold water to the tub, close and latch the door, and pump out the water by slowly turning the control dial until a drain period is reached. Repeat if necessary. (Page 14)
How do I use the ENERGY SAVER drying option, and how much energy does it save?
Select the ENERGY SAVER option before starting your cycle; this turns the drying heater off so dishes dry naturally over a longer period, such as overnight. If you need dishes sooner, open the dishwasher door after the cycle is complete to reduce the natural drying time. Use of this option reduces electrical energy used by the model approximately 10% for the Normal cycle. (Page 4)
