Philips / Saeco Error 14: overheated

Error 14 means: Machine has overheated.

Short answer. The boiler reads hotter than it should. Once after heavy steaming it is harmless; repeatedly on a cold start it means the temperature sensor (NTC) is drifting or its wiring is bad, and the machine is heating on wrong information.

How to fix Error 14

  1. Switch off and leave it for 30 minutes to cool.
  2. Switch on and run a cup of hot water.
  3. If Error 14 returns on a cool machine, descale (scale changes how the sensor sees the boiler).
  4. If it still returns, the NTC sensor needs replacing; the part is cheap but it sits on the boiler inside the machine.

When to stop and call a repairer

A machine that overheats repeatedly should not be left on unattended.

What it costs

Parts: NTC sensor $20 to $40.

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.
