When your dishwasher suddenly starts flashing odd numbers or letters on the display, it can be confusing and concerning. These cryptic codes are your appliance’s way of communicating specific issues or faults. Learning what your dishwasher’s error codes mean is an essential step in diagnosing and resolving problems.
At Melbourne Dishwasher Repairs, we want to help you better understand some standard dishwasher error codes. Familiarizing yourself with these codes will allow you to troubleshoot fundamental problems and determine if a repair technician is needed.
Why Do Dishwashers Have Error Codes?
Modern dishwashers contain innovative internal monitoring systems that are designed to detect faults or issues. When a problem is identified, an error or fault code will display on your dishwasher’s screen.
Some common reasons an error code may appear include:
1 – A malfunctioning component
2 – An obstruction or blockage
3 – A drainage issue
4 – A faulty electronic control board
5 – Sensor problems
6 – Overheating
7 – Low water pressure
The error codes help appliance repair techs quickly identify the issue when servicing your dishwasher. But they also allow you to troubleshoot some fundamental problems on your own.
What Do Dishwasher Error Codes Mean?
While codes vary slightly across dishwasher brands, here are some standard error codes and their meanings:
E1 – A long fill time. Indicates the appliance is taking too long to fill with water. Potential causes include low water pressure, a clogged water inlet filter, or a defective water inlet valve.
E4 – The dishwasher is taking too long to heat water. This could point to problems with the heating element or thermistor.
E5 – The water protection system has been activated. The anti-flood sensor has detected excess water, meaning there is likely an internal leak.
E6 – Overflow condition. This code also signifies an internal water leak.
F1 – Long drain time. The dishwasher can’t correctly drain water, which is often due to a clog or obstruction in the drainage system.
F2 – Drain pump system fault. Indicates an issue with the drain pump, such as a jammed impeller or defective pump motor.
F7 – Heating system fault. This points to an issue with the heating element, thermostat or thermistor.
F9 – Drain pump fault. Commonly indicates a seized or blocked drain pump impeller.
FL – Flood condition inside the dishwasher. Signifies an internal leak.
LO – Low voltage condition. This occurs when the supply voltage has dropped below the optimal operating level.
When to Call a Repair Technician
If you’ve diagnosed that your error code points to a complex repair, like replacing a pump or valve, it’s best to call a professional service technician. Our experienced staff can accurately assess the problem and make the necessary repairs.
But for issues like a clog or obstruction, you can resolve the problem yourself. Always unplug the dishwasher before inspecting internal components like filters and hoses. Refer to your owner’s manual for step-by-step troubleshooting tips specific to your model.

When Error Codes Persist After Troubleshooting
Sometimes, even after troubleshooting the suspected issues based on a particular error code, the dishwasher will still display the same code again. This usually indicates there is a more complex underlying problem that requires a professional repair.
Reasons why an error code may persist after you’ve tried fixing the obvious issues:
- The original error was a symptom of a more significant electrical or mechanical fault
- There are multiple failures within the system
- The control board software needs reprogramming
- There is a break in a wire that is inaccessible
- The issue was misdiagnosed based on the code
- Debris or obstructions got dislodged, but the sensor is still faulty
If you’ve made a concerted effort to fix the problem indicated by the error code, yet it still pops back up, avoid endless frustration and call our service team. Our techs have advanced diagnostic tools and skills to get to the root of persisting dishwasher error codes. We’ll thoroughly examine your appliance and make the necessary repairs to stop those cryptic codes for good.
Step-by-Step Troubleshooting Tips for Common Error Codes
When a dishwasher error code appears, try these basic troubleshooting steps before calling for service:
For E1 (long fill) errors:
– Verify that the water supply valve behind the dishwasher is fully turned on. Check for kinks in the water inlet hose.
– Clean out the water inlet filter located inside the dishwasher. It may be clogged with debris.
– Test your home’s water pressure to confirm it’s above 30 psi. Use a pressure gauge on your exterior hose bib.
– Inspect the water inlet valve for any cracks or defects. Use a multimeter to test valve continuity.
– Make sure the float switch inside the dishwasher has not tripped. Gently push up on the switch to reset it.
For F1 (long drain) errors:
– Remove and clean the drain pump filter. Check it for obstructions.
– Verify the kitchen sink drain line has no clogs or kinks under the sink. Use a drain snake if needed.
– Pour 1 cup of white vinegar into the dishwasher and run a short cycle to release any built-up grease deposits.
– Inspect the drain hose where it connects to the sink tailpiece. Make sure it’s elevated properly and securely fitted.
– Test the drain pump motor. Disconnect power first, then check if the pump spins freely by hand.
For F7 (heating fault) errors:
– Check if debris is blocking the dishwasher heating element. Remove any obstructions.
– Use a multimeter to test the heating element’s resistance. Consult your manual for proper readings. Replace it if defective.
– Verify the heating element wiring is intact and securely connected.
– Make sure the thermostat or thermistor is clipped securely to the tub and wires are connected properly.
