What to do
- Reset it
Unplug for 10 seconds on a front-loader, or for 5 minutes on a top-loader (especially in a humid room), then restart.
When to call an engineer
If it comes back, the sensor needs an engineer.
A repair visit will usually check the pressure sensor and the thin air tube that connects it to the drum.
- Note the model and serial number. They're on a label inside the door, around the door frame or on the back.
- Write down the exact code, and what the appliance was doing when it appeared.
- Check whether it's still under warranty. If it is, the repair may cost you nothing.
