If your Philips coffee machine gets stuck during the descaling cycle or the descale light won’t turn off — you’re not alone. Here’s a complete troubleshooting guide to help you fix descaling issues, clear persistent alerts, and ensure smooth operation.
🔍 Common Descaling Problems
| Issue | Cause | Fix |
|---|---|---|
| Descale light stays on | Incomplete cycle or skipped rinse | Repeat rinse cycle fully |
| Stuck on “Descaling” message | Not enough water / AquaClean installed | Add more water and remove filter |
| Water not dispensing | Blockage or empty tank | Check tank, clean spout |
| Loud noise during cycle | Air in the system | Run water circuit again |
⚠️ 1. Descale Light Won’t Turn Off
If you’ve completed the descaling process but the machine still shows the descale alert:
- Ensure the rinse phase was completed. Some models require a second rinse cycle.
- Restart the cycle manually by holding the Espresso and Lungo buttons (model-dependent).
- Avoid unplugging during the process — this can cause the system to freeze.
❌ 2. Machine Gets Stuck Mid-Cycle
This usually happens when the water tank runs dry or the AquaClean filter is still inserted.
Solution:
- Remove the AquaClean filter during descaling
- Fill the tank above the MAX line
- Use only Philips descaler, not vinegar or unknown brands
🛠️ 3. Error Messages During Descaling
Some machines may flash lights or display errors like:
- “Refill water tank” (even if full)
- “Descale cycle not completed”
Fix tips:
- Reseat the water tank firmly
- Empty and clean the drip tray
- Restart the descaling cycle from the beginning
📄 4. Step-by-Step Quick Reset (Universal Fix)
- Turn off the machine
- Remove AquaClean filter
- Fill tank with clean water
- Hold down Espresso + Lungo for 5 seconds (or refer to manual)
- Run fresh rinse
🪖 Prevent Future Issues
- Always remove filters before descaling
- Use official descaling solution
- Don’t interrupt the cycle once started
- Rinse thoroughly after descaling

🤔 FAQ
Why is my descale light still on after finishing the cycle?
Most likely the rinse cycle wasn’t completed fully. Some models require a second rinse.
Can I descale with the AquaClean filter inserted?
No — remove the filter before descaling, or the cycle may fail.
What if my machine says “refill water” but the tank is full?
Check tank position, ensure it’s seated correctly. Refill and try again.
How do I reset the descaling mode manually?
Hold the Espresso + Lungo buttons for 5 seconds on most models. Refer to your manual.
