Hi-Temp & Heat Dry Errors in Frigidaire Dishwashers

Heat Delay

• If the water in the dishwasher isn't hot enough, it'll display a code of "HO." Technically speaking, this error code isn't an error -- the dishwasher is simply informing you that it's waiting for the water to get hot before it continues washing your dishes. You can avoid this problem by running hot water in your kitchen sink for a few minutes before you start the dishwasher so that the water will be hot enough to wash your dishes immediately.

Vent Problems

• If the vent is open or fails, your dishwasher will display an error code of "UO" or "UF." "UO" simply means the vent is open. You can check the vent to make sure it's working properly. If you find any blockage, replace the vent. If you get a code of "UF," the vent fan needs to be replaced. Contact your service technician to replace the fan.

Rinse Aid Low

• If the rinse aid in the dishwasher's rinse aid dispenser gets low, your dishes may not dry properly or you may see water spots and streaks on your dishes. Rinse aid helps soften your water so that droplets don't stick to your dishes while drying. Your Frigidaire dishwasher may display an error code of "LO." This code means the rinse aid is extremely low. You can refill the rinse aid dispenser even if you don't yet see this error code.

Loading Problems

• Even if your dishwasher is working correctly, your dishes won't dry properly if you overload the dishwasher or load it incorrectly. Don't put all your silverware facing the same direction --if you do, it creates a nesting effect in which some silverware doesn't get enough access to water and heat. Cups and glasses may need to be towel dried even after going through the heat cycle because of their shape.
