Frigidaire Dishwasher Diagnostic Mode
Remember, you need to put your Frigidaire dishwasher on diagnostic mode to identify hidden faults that could indicate a possible fault. Here are the steps to do it:
- Locate the High-Temperature and Start/Cancel buttons and press them simultaneously
- Hold the two buttons for a few seconds until the dishwasher goes into self-test
- You can tell if that’s the case when the dishwasher displays the code 01 or when the indicator light comes on
- When it does, release the buttons and wait a few seconds for the dishwasher to run the self-test and display any potential error codes.
- Note down the error code and use the guide below to find its meaning and troubleshoot it.
Frigidaire Gallery Dishwasher Error Codes Reset
Before anything, you may want to try resetting the error code you find. That involves these options:
Option 1 – Hold Start/Cancel for a few seconds until the fault code disappears
Option 2 – Unplug the dishwasher and wait 5 minutes for the old memory to clear, which should clear the error code.
And Option 3 – Flip off the dishwasher’s circuit breaker for 5 minutes to erase old memory and the fault code in the process
Common Frigidaire Gallery Dishwasher Error Codes Discussed!
Below are the top 18 Frigidaire Gallery dishwasher fault codes:
1. Frigidaire Gallery Dishwasher Error Code i10
Meaning – Low Water Level
If the water level drops abnormally, you can expect the error code i10 to appear on your Frigidaire Gallery dishwasher. In most cases, that happens due to one of these issues:
- A blocked water inlet hose
- The supplying water faucet is off
- Inadequate water pressure (perhaps below 20 psi)
Fix
Check if the water inlet hose is kinked and untwist it. Then, ensure the water faucet is on to allow water to flow to the dishwasher. And if the pressure isn’t enough (which you can measure with a home water pressure gauge), call a plumber.
2. Frigidaire Gallery Dishwasher Error Codes i20
Meaning – Restricted Drainage
The error code i20 (or sometimes i40 or iF0) appears when a Frigidaire Gallery dishwasher won’t drain. It shows restricted drainage resulting from a clogged filter, drain hose, knockout plug, or garbage disposal.
Fix
Inspect the filter, drain hose, knockout plug, and garbage disposal for clogging and clean off any clogs on them.
3. Frigidaire Gallery Dishwasher Error Codes i30
Meaning – Water Leakage at The Base Level
Sometimes, a Frigidaire dishwasher leaks at its base, and when that happens, it shows the error code i30, which could result from a clogged pressure sensor, water inlet valve, impeller, or drain pump.
Fix
Examine the pressure sensor, water inlet valve, impeller, and drain pump for excessive clogging or obstruction and clean them.
4. Frigidaire Gallery Dishwasher Error Code i50
Meaning – Wash/Drain Pump Fault
You expect your Frigidaire Gallery dishwasher to communicate when the wash/drain pump malfunctions. It often does that by displaying the error code i50.
Fix
Try to reset your Gallery dishwasher to activate the otherwise failing drain pump.
5. Frigidaire Gallery Dishwasher Error Code i60
Meaning – Water Heater Fault
The dishwasher will display the error code i60 if there’s an issue with the water heating. Overall, this could be a case of a faulty heating element that won’t heat the water or a defective thermistor that won’t detect any temperature changes. And if it’s neither of them, it could be a malfunctioning or control panel.
Fix
Start by replacing the heating element; if that doesn’t work, replace the thermistor. But if the control panel is nonresponsive, replace it first.
6. Frigidaire Gallery Dishwasher Error Code L0
Meaning – Inadequate Rinse-Aid
You can expect your Frigidaire dishwasher to display the error code L0 if the Rinse Aid is insufficient. So, all you’ve to do is check the Rinse-Aid dispenser to see if it’s empty.
Fix
Refill the Rinse-Aid dispenser if it’s empty
7. Frigidaire Gallery Dishwasher Error Code UF
Meaning – Vent Fan Motor Fault
The error code UF appears when there’s an issue with the vent fan motor. In most cases, it’s a case of faulty wiring between the vent fan motor assembly and the electronic control board (ECB), which brings about a miscommunication between them.
Fix
First, reset the dishwasher; if it doesn’t work, replace the vent fan. But if that doesn’t work, replace the ECB.
8. Frigidaire Gallery Dishwasher Error Code PF
Meaning – Power Failure
The error code PF is what it implies – Power Failure. This error code appears when there’s a drop in the dishwasher’s power supply of at least 10%.
Fix
Reset the dishwasher to recycle its power.
9. Frigidaire Gallery Dishwasher Error Code CD
Meaning – Close The Door
The error code CD reminds you to ‘close the door.’ So, expect this fault code to appear due to an unlatched dishwasher door. Sometimes, however, the issue is not forgetting to shut the door but a defective door latch that won’t allow you to secure the door firmly.
Fix
See if there’s any reason the door won’t latch. If the door latch is damaged, replace it.
10. Frigidaire Gallery Dishwasher Error Code UO
Meaning – Open Vent
When the fan vent is perceived as open, the error code UO pops up on a Frigidaire Gallery dishwasher. Nonetheless, that could be a case of the fan vent assembly failing.
Fix
Replace the fan vent assembly
11. Frigidaire Gallery Dishwasher Error Codes ER
Meaning – Membrane Switch Fault
You can expect the dishwasher to show the error code ER when there’s an issue with the membrane switch. If so, the trigger could be a wiring fault between the keypad and ECB. But still, the code could result from a stuck key.
Fix
First, check for a stuck key and try to free it. Then, try to reset the dishwasher, but if that doesn’t work, have an expert check for any wiring fault involving the ECB and keypad.
12. Frigidaire Gallery Dishwasher Error Code CL
Meaning – Unlatched Door
You can expect your Frigidaire dishwasher to display the error code CL when the door is perceived open. That often happens due to a faulty door switch or control board.
Fix
First, replace the door switch; if the error code persists, replace the control board.
13. Frigidaire Gallery Dishwasher Error Code ICO
Meaning – ECB Fault
The last thing you want is your dishwasher’s electronic control board malfunctioning. It, however, can happen, and when it does, the error code ICO pops up.
Fix
Reset the dishwasher to clear any corrupt memory from the ECB.
14. Frigidaire Gallery Dishwasher Error Code LOC
Meaning – Locked Door
The code LOC means a ‘Locked Door.’ That is a normal occurrence before a cycle starts.
15. Frigidaire Gallery Dishwasher Error Code SD
Meaning – Activated Detergent Dispenser
Frigidaire dishwashers display the code SD when the detergent dispenser activates during the relay test. This is another regular code.
16. Frigidaire Gallery Dishwasher Error Code DP
Meaning – Activated Drain Pump
Another regular code that you can expect is DP. It shows an activated drain pump during the relay test. So, no action here.
17. Frigidaire Gallery Dishwasher Error Code TU
Meaning – Turbidity Sensor Error
The error code TU appears on a Frigidaire dishwasher when there’s an issue with the turbidity sensor. If that’s the case, the trigger could be a wiring fault between the turbidity sensor and ECB.
Fix
Reset the dishwasher, and if that doesn’t work, check for loose wiring between the turbidity sensor and ECB and fix them. But if that’s not the case, replace the turbidity sensor.
18. Frigidaire Gallery Dishwasher Error Code CE
Meaning – Configuration Error
Lastly, the error code CE appears to indicate a configuration fault. That happens when there’s loose wiring or using the wrong replacement part.
Fix
First, reset the dishwasher, but if that doesn’t clear the code, check for loose wiring or wrong replacement components.
Concluding Thought:
Above are the various Frigidaire Gallery dishwasher error codes you can try to troubleshoot DIY. It starts with identifying the meaning of the error code and its most likely trigger. Then, address the trigger, but before anything, you may want to try resetting the dishwasher. Doing so may result in clearing the error code.
