Have Frigidaire FDB520RHB model dishwasher but it doesn't seem to heat dry the dishes. Also the dishes come out spotty.

Hello Bette Good, thanks for your inquiry!

I see that you have replaced the heating element inside of your Frigidaire dishwasher but the dishes are not drying and the water is not hot. You may want to check the water temperature going into the dishwasher and that can be tested by using the sink closest to the dishwasher. The water temperature needs to be 120 degrees, the hotter the water the hotter the dishes will become to assist with drying.

Also check to assure that the rinse aid has been filled that will help with the drying of the dishes. I hope this information has been helpful. -Matt

Make sure you have the heated dry setting selected, use rinse aid at all times, and make sure the unit is getting hot. If it is not, or there is no steam generated when you open the unit after cycle - have a professional diagnose the heating element.

Hello,
One common issue on these units is the heater wire will fall off. If this happens, the dishwasher will not heat. Also make sure the rinse agent is full. On most of the newer dishwasher rinse agent must be used to help dry the dishes.

The problem is hard water. Go to www.dishwasherfilter.com. They have a new product out that solves this problem once and for all. It filters the water entering your dishwasher and removes the hard minerals that cause these spots. Very affordable and guaranteed to leave your dishes looking amazing every time.

If the dry cycle has a problem, check these:

Heating element
Drying fan
Thermostat
Heating element Your dishwasher has an electrical heating element that helps to dry the dishes. If the element is burned out, the dishes won't dry properly, and you need to replace the element.

Drying fan Many high-priced dishwashers have a small fan that blows air or heated air into the dishwasher to speed up the drying process. If the fan is defective, you need to replace it.

Thermostat Some dishwashers have a thermostat that monitors the drying temperature. If the thermostat is defective, the heating element may not cycle on or off properly. If that's the problem, you need to replace the thermostat.

Check your hot water supply. It should be at least 125 degrees. Are the dishes spotty or still dirty with old food? Try to pre-rinse your dishes before putting them into the dishwasher. You can also run your hot water until it's nice and hot coming from the sink before turning your dishwasher on. If they're spotty, use less or better quality detergent. My guess is going to be water temperature or pressure.

Did you ever learn why the heat was not drying dishes? We have the same problem.

If the dishes are made of plastic they will be wet , they don't retain heat when in the drying cycle!

How old is the dishwasher? Check the front control panel for a AIR DRY / HEAT DRY switch. Perhaps the switch is in the AIR DRY position. If so and you really want to HEAT DRY your dishes, set the switch for HEAT DRY. Otherwise: Second, it is not a bad thing to let your dishes AIR DRY. It saves money! Just open the Dish Washer door after the last rinse cycle has finished and let the dishes AIR DRY manually. In a hour or so they can usually be put away. Works for me :)
