Philips / Saeco Error 05: air in the water circuit
Error 05 means: Air is trapped in the water circuit.
How to fix Error 05
- Empty and refill the tank; if you have just fitted an AquaClean filter, shake it for five seconds, hold it upside down in a jug of water until no bubbles rise, then refit.
- Push the tank fully home.
- Switch on, wait for heat-up, then dispense two or three cups of hot water to purge the circuit.
- If the pump still only wheezes, descale; a scaled inlet will not let the pump prime.
When to stop and call a repairer
If the pump runs continuously and never primes after descaling, the pump or a valve has failed.
What it costs
Parts: Nothing for priming; pump $30 to $50.
Service: Out-of-warranty manufacturer service for a super-automatic is typically $250 to $500 including return shipping; independent espresso repairers are usually cheaper for a single part.
Worth repairing? Yes.
FAQ
What does Error 05 mean on the Philips / Saeco?
Air is trapped in the water circuit. The pump is running but drawing air rather than water, so no pressure builds. A freshly fitted AquaClean filter that was not primed is the usual cause; an empty tank, a tank not pushed onto its valve, or scale in the inlet are the others.
Can I fix Error 05 myself?
DIY difficulty: easy. Empty and refill the tank; if you have just fitted an AquaClean filter, shake it for five seconds, hold it upside down in a jug of water until no bubbles rise, then refit. Push the tank fully home.
