What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Check of the water circuit
What they doPhilips service checks the water intake from the tank and the pump flow, with the machine opened and disconnected where needed.
They must show youthe flow checked and the point where air got in or flow stopped.
In writingthe cause found and any part replaced, with its reference.
Hot water and coffee test
What they doWhen finished, the technician runs hot water and makes coffee without the warning returning.
They must show youwater and coffee coming out with no warning.
In writingthe test carried out and the date.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Purge through the frother
- Who:
- you, no tools.
- How:
- fill the water tank, place a cup under the classic milk frother and press the flashing start/stop button; the machine dispenses hot water.
- Result that matters:
- water flowing steadily and the lights going off.
- If they go off:
- the air is out.
- If they stay:
- go to the purge without the filter.
- Evidence to keep:
- a note of whether the tank had run empty before the warning.

Purge without the AquaClean filter
- Who:
- you.
- How:
- switch off, empty the tank, remove the AquaClean filter if fitted, fill with fresh water, switch on, let it heat up and dispense 2 to 3 cups of hot water.
- Result that matters:
- water flowing without breaks and the warning gone.
- If it is gone:
- refit the filter and dispense 2 to 3 cups of hot water again.
- If it remains without the filter:
- contact Philips Consumer Care.
- Evidence to keep:
- a note of what you did and the result.

Check with the filter fitted
- Who:
- you.
- How:
- with the AquaClean filter back in, dispense 2 to 3 cups of hot water, as Philips says.
- Result that matters:
- knowing whether the warning returns only with the filter.
- If it does not return:
- the machine works normally.
- If it returns only with the filter:
- tell Philips service.
- Evidence to keep:
- the date the filter was fitted.

What it means
Philips says this combination, alarm light on and start/stop button flashing, means air is trapped inside the machine's water circuit. Air stops the pump moving water normally. The fix is to let hot water out to purge it; if that is not enough, Philips asks you to remove the AquaClean filter and dispense 2 to 3 cups of hot water. The warning does not prove a pump fault: it describes air in the circuit.

Symptoms and causes
Probable causes · in order
- Air in the water circuitCommon
Usually left after the tank runs dry; running hot water through the frother lets the air out and the light goes off.
Evidence: A warning light on my Philips espresso machine is not turning off
- Air linked to the AquaClean filterPossible
The simple purge is not enough; removing the filter and running 2 to 3 cups of hot water solves it, then it is repeated with the filter back in.
