What E01 actually means
The fridge freezer has lost a reliable reading from the freezer's temperature sensor, so it can't tell how cold the freezer actually is.
E01 means the freezer temperature sensor is reading as short circuited or disconnected. Without a trustworthy reading, the control board can't run the cooling cycle properly, so it flags the fault and falls back to a fixed running pattern or stops cooling correctly. Food temperatures may drift, in either direction, until it's put right.
What usually causes it
- Failed freezer temperature sensor
- Loose or corroded plug on the sensor wiring
- Damaged sensor cable, often where it passes into the cabinet
- Fault on the main control board
- Moisture or ice build-up around the sensor connection
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 appliance off at the wall for a minute, then switch it back on — occasionally the code clears if it was a one-off glitch
- Check the doors are closing fully and the seals aren't holding them ajar, as constant warm air makes icing worse
- Check a thermometer or the food itself to see whether the freezer is still holding temperature
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.
