Fridge
E3
The E3 error code on a Hotpoint fridge signals a problem with the freezer compartment temperature sensor — it’s a moderately serious fault that can cause your food to spoil if left unresolved.
What does this error mean?
The E3 code means your Hotpoint fridge-freezer’s control board has detected that the freezer temperature sensor (also called an NTC thermistor) is either reading an abnormal value or has stopped sending a signal altogether. The appliance can no longer accurately measure the freezer temperature, so it may run the compressor incorrectly — overcooling, undercooling, or cycling erratically. Left unattended, this leads to inconsistent freezer temperatures and potential food spoilage.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the fridge: unplug it from the mains for 10 minutes, then plug it back in. If E3 clears and doesn’t return within 24 hours, a power glitch was the cause — no further action needed.
Check the door seals: run your hand around the freezer door edge feeling for cold air escaping. A leaking seal causes ice build-up around the sensor. Replace the seal yourself if it’s cracked or deformed — genuine Hotpoint seals cost £15–£35 online.
Manually defrost the freezer: turn the appliance off, remove all food, and leave the freezer door open for 24–48 hours with towels on the floor. Once fully defrosted, power it back on and check if E3 returns. Ice around the sensor can cause false fault readings.
Locate and inspect the freezer sensor: it is typically a small probe clipped near the evaporator coils at the back of the freezer compartment. Check that its connector plug is fully seated and the cable isn’t visibly chafed or broken. Re-seat any loose connection firmly.
Replace the NTC thermistor: if the sensor feels brittle, corroded, or you have a multimeter and can confirm it reads outside the normal range (typically 5kΩ–30kΩ at 0–25°C), order a replacement Hotpoint thermistor (around £10–£25). Unclip the old sensor, disconnect the plug, fit the new one, and retest.
If E3 persists after a new sensor, do not attempt to replace the main control board yourself — the board involves mains-voltage components and must be handled by a qualified engineer.
📞 When to call a professional
Call a qualified appliance engineer if E3 returns after a full defrost and sensor replacement, as the fault likely lies with the main control board or internal wiring — both involve mains-voltage components. When calling, tell the engineer: ‘My Hotpoint fridge-freezer is showing error code E3 — I’ve already defrosted it and replaced the freezer NTC thermistor.’ This helps them arrive with the right parts and saves on call-out time.
⚖️ Repair or replace?
A professional repair (sensor or control board replacement including call-out) typically costs £80–£170 in the UK. If your Hotpoint fridge-freezer is under 7 years old, repair is almost always worth it — a comparable new appliance costs £350–£700. If the appliance is over 10 years old and the control board needs replacing (£130+ in parts alone), replacing the fridge-freezer is the more economical long-term choice.
