The drying problem is very common in most of the mid to high-range dishwashers out there. You will see a lot of reviews from customers regarding this problem. Most of the time, you just have to check the vent and the rinse aid.
However, sometimes defective components like heating elements and limit switches can also create this problem. So, to get the drying function working again, you will need to replace these defective components.
In this article, we will be going over some troubleshooting steps that should help you fix the drying problem in the Frigidaire dishwasher. So, if you’re having issues with this device just try following the methods mentioned here, and hopefully, your dishwasher will start drying the dishes again.
How to Fix Frigidaire Dishwasher Not Drying?
- Inspect Limit Switch
Depending upon the model of the Frigidaire dishwasher, you will need to check the limit switch to see if it is working properly. The job of this switch is to regulate the temperature of the water and the heating element. However, if the switch has gone bad then it will cut off the power supply to the heating element.
This switch ensures that the water from the spray arms has a moderate temperature. If the water or the heating element gets too hot then the power supply is removed by this limit switch. After the water has cooled down a bit then the power supply is continued.
Sadly, this switch can go bad after a few years. So, if you have had this dishwasher for a long time then the drying problem may be caused by the bad limit switch. The replacement switch won’t cost you much and you can replace it yourself at home.
After ordering the replacement online, you can use the owner’s manual for your specific model to access the limit switch. Then just take out the bad limit switch and install the new one in its place. That should help you with the drying issue.
- Increase Water Temperature
According to the company, to avoid drying issues the water temperature should be more than 45 degrees Celsius. So, make sure to increase the water temperature on the mainline before running the cycle on your Frigidaire dishwasher. The increased water temperature will help with the heating and drying functions of the dishwasher.
Another tip for users is that you should run the kitchen tap for a few minutes to remove any cold water stuck in the mainline. After you’re getting hot water from the kitchen tap, then you can start the cycle on your dryer. That will ensure that you won’t supply any cold water to the dishwasher and it can operate better on hot water.
If the water supply has cold water, then the heating element won’t be able to increase the water temperature enough. So, that way the water won’t turn into steam and exit out of the vents installed in your dishwasher. This is why it is so important to regulate the temperature of the water supply to your dishwasher.
- Fix Damaged Vents
As mentioned above you need the water to turn into steam and then exit out of the vent. If the vents are not opening up properly or there is an obstruction then you can just clean the vents and that should fix your problem. However, if the vents are damaged then you will have to buy a replacement for them.
If the steam is entrapped in the dishwasher and not allowed to escape then it will cool down and your dishes will get wet again. So, to avoid this some models also have a vent fan that helps in removing the steam from the dishwasher. So, if you own a model with a vent fan then make sure to also check the motor.
You will need to use a multimeter to check the power supply to the motor. If there are no issues with the power supply then the last option left is to replace the vent motor. Other than that, there is not much that you can do about this problem and you will have to install the new motor in your vent fan. That will help remove the steam and dry your dishes.
- Cracked Heating Element
Another reason why your Frigidaire can have drying issues is because of a cracked heating element. So, what you need to do is to remove the racks from your heating element and then inspect the heating around the base for possible damages. If the heating element has cracks in some places, then you will need to buy a new heating element for your dishwasher.
Sometimes, the heating element can also break from the inside. So, even if the heating line looks fine, it does not mean that it is working perfectly. You might need to completely remove the heating element from the dishwasher and then use a multimeter to check the heating element for continuity.
It can take a lot of time and in some models, you might even need to remove the whole dishwasher first to remove the heating element from the base. However, after checking with the multimeter, you will know for sure whether or not you have issues with the heating element. If you don’t get the desired reading on the multimeter then you will need to get the heating element replaced. Hopefully, that will fix your dishwasher.
- Ask Frigidaire
If you have followed all the steps mentioned here but still can’t figure out the issue with your dishwasher then the best option for you is to send Frigidaire an email regarding this issue. You can also call their company number and they will connect you with a professional that can help you navigate around the problem.
In most cases, users just had to replace the limit switches and increase the water temperature on the mainline to fix this problem. However, it is also possible that you have a bad unit. If you bought the Frigidaire dishwasher recently then claim the warranty for replacement.
