What E05 actually means
The machine can't read the water temperature properly, or the water isn't heating, so it stops rather than carry on.
E05 is the washer temperature sensor (NTC) fault. The control board watches the sensor while the heater runs — if the temperature doesn't rise as expected, or the sensor reading is nonsense or the sensor is disconnected, it flags E05 and halts the wash. It's usually either the sensor itself, its wiring plug, or the heating element that has failed.
What usually causes it
- Faulty water temperature sensor
- Loose or corroded sensor connection
- Failed heating element
- Water heating circuit or control board fault
- Damp or damaged wiring behind the drum
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the machine off at the wall for a minute, then switch back on and try a short cycle — occasionally clears a one-off glitch
- Try a cold wash (30°C or cold) to see whether the fault only appears on heated programmes — useful information for the engineer
- Check the machine isn't standing in a very cold, unheated space, which can push the sensor reading out of range
When to call someone
This one usually needs an engineer once you have tried the checks above. We cover Nottinghamshire, Derbyshire and Leicestershire, and it's £66 including VAT for an engineer to come out and diagnose it — £84 in total if it's repaired on the visit with no parts needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Outside our area? The explanation above still stands — take it to a local engineer and tell them the code. Knowing it saves them time and you money.
