Why Is Frigidaire Dishwasher Not Draining? 7 Solutions That Will Help You Out
It can be really frustrating when your dishwasher cannot drain residual water. The used water starts to smell bad after it remains in the dishwasher undisposed. This makes your kitchen very unbearable to stay in when the dishwasher’s door is opened. Hiring an expert to repair the drainage system is also expensive.
The easy way out is knowing how to fix the dishwasher by yourself. It is not very complex to repair the drainage system as most people tend to think. There are different models of dishwashers, and this may cause a tiny bit of variation in the repair process. In this article, we will have an overview of why your Frigidaire dishwasher is not draining properly and ways to fix it.
Possible Flaws in the Drainage System and Ways to Fix Them
Identifying the fault as to why your Frigidaire dishwasher is not draining properly is the first step to getting a solution. Here are some drainage flaws that may restrict the drainage process:
1. Drain Hose
The drain hose connects your dishwasher to the garbage disposal. Usually, the connection is located under your sink. The cause of your Frigidaire dishwasher not draining may be because of a clogged drain hose. Restriction of drainage due to a faulty drain hose can occur in two ways:
Kink can result to a puncture in the drain hose. Signs of leakage in the drain hose where there is a kink simplifies your troubleshooting because that is the problem. We recommended that you replace your drain hose if it has developed a kink.
A faulty food chopper in your dishwasher can cause accumulation of food debris hence blockage in the drain hose. The solution is to remove the drain hose from the pump and clean it. You can visit aGuidePro to looking for the drain cleaners. However, this is a temporary solution because the drain hose will block again due to food debris if the food chopper is not repaired.
2. Drain Valves
Drain valves are located near the motor. They are responsible for allowing waste water out of your dishwasher and preventing it from backflow. Most of the times food debris clog the valves restricting water from exiting the dishwasher. Remove the valve and clean off the dirt.
However, if you detect that the valve is faulty, you will need to replace it. Defective valves cannot be repaired. Most faulty valves allow backflow of dirty water back to the dishwasher or do not open completely.
To troubleshoot if the valve is the faulty part. Remove the drain hose and fill water in your dishwasher and try to drain it. Use a bucket to trap the drained water. You will be able to see the valve opening during the draining process and does not close after or it does not drain completely.
3. Drain Pump and Motor
A faulty pump is a rare occurrence in the Frigidaire models, but it can happen. Drain pump utilizes an impeller to drain out water of your dishwasher. The pump can be faulty due to a number of reasons.
A foreign object has clogged the pump. In most cases pieces of broken glass. You can detect a little humming noise from the motor when you start the cycle. This is an indicator that there is a foreign object in the drain pump.
You can fix it by disconnecting the feeder hose and any other connection that can be damaged when moving the dishwasher around. Unscrew the base plate of your dishwasher then disconnect the anti-flood switch.
Usually, the pump is held in place by screws. Unscrew it and then twist and pull it out. You have to be careful with the screws and also when pulling out the pump. If you notice any resistance when pulling out the pump, then check if there is a connection or screw that is holding the pump.
Check the impeller if any debris has clogged it or other foreign objects. You can easily clean it by scraping off the debris. Then try to rotate the impeller with your finger to see if it’s rotating properly.
The motor is not running or running in the wrong direction can be the cause of your Frigidaire dishwasher not to drain water. Check if the motor is rotating in the right direction. If the motor is not rotating then use a meter to check if the circuit reaches the terminals.
In case there is current in the terminals then your drain pump is not working because either there is a problem in the motor’s winding or the motor has seized. We recommend that you replace a seized motor.
If the current does not reach the terminals, then the possible cause may lie on electric control, timer, or door switches. You will need an expert to fix the technical bits if you are not familiar with contacts and electric circuits.
The timer is typically located on the control panel of your dishwasher. It controls the motor and also the drain solenoid. Your Frigidaire dishwasher not draining waste water may be due to a faulty timer. We recommend that you replace a defective timer.
To troubleshoot if your timer is faulty, you need your dishwasher’s wiring and schematics. Different Frigidaire dishwashers have variations in the wiring plan and schematics. You will be able to locate the exact timer contacts that command the drainage system. You can troubleshoot by checking the continuity of the current.
If the current gets in the timer but does not indicate current out, then the timer is defective. If there is current out, then follow the wire until you find where the current breaks. You can replace the wires if you detect a fault in them.
5. Garbage Disposer
The garbage disposer may cause your Frigidaire dishwasher not to drain residual water. The fault may occur during installation, or it is clogged. The drain tube of garbage disposer contains a solid plug that can restrict drainage.
In most cases, this happens to newly installed garbage disposers. Remove the plug and see if the drainage problem is fixed. If you have been using your dishwasher, then you may want to check the garbage disposer for clogs.
Remove the drain hose and clean the joint of the disposer and drain hose. Check if the debris in the clog is made of larger particles. If the particles are larger, then you will also need to check your food chopper.
6. Check ball
Sometimes you see your dishwasher draining, but after a while, you find water at the base of your dishwasher. This may be caused by the backflow of water that is drained from the dishwasher.
A check ball is a small plastic ball in the check valve that prevents backflow of water. When the check ball it stuck, drainage through the check valve is restricted. Use a screwdriver to free the ball and spray lubricant.
7. Clogged Drainage Basket
This is the most common cause of drainage problems in many dishwashers. The drainage contains a filter that prevents food debris from going through. Drain manually all the residual water to expose the drainage basket. You should take caution when doing this because it might be pieces of glass clogging the drainage basket.
The drainage basket is held in place by bolts or screws. Undo them then remove the basket and clean around the filters.
Troubleshooting is the hectic part in repairing your dishwasher drainage system. Once you know, the problem fixing it when you have the right tools is not complicated. There are technical drainage complications that you will need an expert.
Drainage complications that mostly arise from the control panel it is recommended that you consult an expert if you do not know how to navigate around the problem.
