What does the AEG i50 error code mean?
i50 indicates a fault with the main circulation (wash) pump — the pump responsible for spraying water through the spray arms to wash the dishes. Without a functioning circulation pump, no washing action takes place at all. This is a more serious fault than a drain pump failure.
🔍 Symptoms
- Machine fills with water but no washing action occurs — spray arms are stationary
- A humming noise from the machine but no water spray can be heard
- Dishes completely unwashed despite a full cycle completing
- No water jets visible if door is carefully opened mid-cycle
- Error code appears approximately 5–10 minutes into the main wash phase
How to fix the AEG i50 error code
- Clean the filter thoroughly — a heavily blocked filter can starve the circulation pump and trigger i50.
- Check the spray arms — ensure they are not blocked and can spin freely by hand. Remove and rinse them if clogged.
- Check for any hard objects (glass fragments, etc.) that may have reached the circulation pump.
- If the pump can be heard buzzing/humming but no water sprays, the pump impeller may be jammed. Access the circulation pump (usually requires accessing the base of the machine) and clear any obstruction.
- If no buzzing is heard at all, the pump motor may have failed electrically. Test with a multimeter and replace if necessary.
Frequently Asked Questions (FAQ)
Q: What is the difference between the drain pump and circulation pump in an AEG dishwasher?
A: The circulation pump sprays water at pressure through the spray arms during the wash cycle. The drain pump removes waste water at the end of each phase. They are separate components with different fault codes (i20 for drain, i50 for circulation).
Q: Can the circulation pump be replaced as a DIY job?
A: It requires more confidence than a filter clean. The machine needs to be tilted or laid on its side to access the sump from underneath. If comfortable with appliance repair, it is a DIY-achievable task.
Q: Is i50 a reason to consider replacing the AEG dishwasher entirely?
A: On a machine less than 8 years old, repair is almost certainly more cost-effective. On machines older than 12 years, compare repair cost (£35–£90 parts + labour) against current replacement prices
