1. AE Error Code – Leak Alert
Your dishwasher is sounding the alarm that water may be leaking. Yikes! But don’t panic yet—sometimes this can be an easy fix.
What to Do:
- Check for water pooling at the bottom of the dishwasher or underneath it.
- Make sure the dishwasher is level tilted machines can trigger a false leak alert.
- Inspect the door gasket (the seal around the door) for cracks or damage. If it’s worn out, a simple gasket replacement might solve the issue.
- Double-check your water connections to ensure no hoses are loose.
2. OE Error Code – Drainage Problem
The OE code means your dishwasher is having trouble draining water. It’s likely clogged somewhere along the way.
How to Fix It:
- Examine the dishwasher filter (it’s usually at the bottom) and remove any food debris or gunk. Gross but oh-so-satisfying!
- Inspect the drain hose for kinks or blockages.
- If the issue continues, try cleaning the sink’s garbage disposal sometimes a clogged disposal can affect the dishwasher’s drainage.
3. HE Error Code – Heating Issue
Uh-oh! Your dishwasher is having trouble heating the water. This is super important because hot water helps clean those dishes sparkling clean!
Steps to Troubleshoot:
- Ensure the water heater in your home is working properly and delivering hot water to your dishwasher.
- If everything checks out but the issue persists, the problem could be within the heating element. You might need a professional for this one (or an adventurous DIY spirit!).
4. IE Error Code – Water Fill Problem
This code means your dishwasher isn’t filling up with water as it should.
What to Check:
- Is the water supply turned on? This one might seem silly, but hey it happens to the best of us!
- Inspect the water hose for any bends, blockages, or clogs stopping the flow.
- Check the inlet valve, which controls water entry into the dishwasher. If it’s damaged, it’ll likely need to be replaced.
5. E1 Error Code – Low Water Level
Your dishwasher thinks it doesn’t have enough water to run properly.
How to Fix It:
- Ensure the water supply line is fully open.
- Double-check for leaks or blockages in the water line.
- If the issue continues, the water inlet valve might need replacement.
6. PF Error Code – Power Failure
This is your dishwasher’s way of telling you it lost power during a cycle.
The Quickest Fix:
- Press the power button to restart the dishwasher.
- Check your circuit breaker or power outlet to ensure the dishwasher has proper power supply. That’s it easy!
7. CL Message – Child Lock
Not technically an error code, but this confuses so many people! The “CL” message means the child lock feature is activated, stopping the buttons from working.
How to Unlock:
- Look for the child lock button (or button combo, depending on your model) in your dishwasher’s manual. Then hold it down for 3–5 seconds. Voilà!
