Common questions
Quick answers for this fault
What should I check first for AE / E1?
Start with water leak inside dishwasher. If that checks out, continue through the diagnostic sequence above rather than replacing a part based on the code alone.
Does AE / E1 always mean Leak Sensor / Leak Source is bad?
No. An error code identifies the condition the control detected, not a guaranteed failed part. Confirm the likely causes and wiring first. The exact OEM part number varies by model and production revision. Verify the complete model number before ordering.
When should I stop troubleshooting AE / E1 myself?
Stop if the next step requires live electrical testing, sealed-system work, gas or combustion service, or any procedure outside your training.
