Fridge
E7
The E7 error code on a Hotpoint fridge signals a fault with the defrost circuit — specifically the defrost sensor or heater — and should be addressed promptly to prevent food spoilage and ice build-up damage.
What does this error mean?
The E7 code means your fridge’s control board has detected an abnormal reading from the defrost temperature sensor (also called the defrost thermistor), or the defrost heater has failed to raise the evaporator temperature during a defrost cycle. In plain terms, the appliance can’t confirm that frost is being cleared from the evaporator coils as it should be. Left unchecked, ice builds up on the evaporator, airflow is blocked, and the fridge loses its ability to cool properly.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the fridge: Unplug it from the mains, wait 5 minutes, then plug it back in. If the E7 code clears and doesn’t return within 24 hours, the fault may have been a temporary glitch.
Manual defrost: Unplug the fridge and leave both doors open for 24–48 hours with towels on the floor to catch meltwater. Heavy ice build-up can trigger E7 by preventing the defrost cycle from completing — a full manual defrost sometimes resolves it.
Check the freezer compartment for excessive ice: If you see a thick wall of ice around the back panel of the freezer, this confirms a defrost system failure. Note this before calling an engineer.
Inspect the defrost thermistor (if comfortable doing so): With the fridge unplugged, remove the freezer back panel (usually 2–4 screws) to access the evaporator. The thermistor is a small sensor clipped to the evaporator coils. Check for visible damage, corrosion, or a disconnected wire. If the connector is loose, reseat it firmly.
Test or replace the defrost thermistor: Replacement thermistors for Hotpoint models are widely available online (search your model number + ‘defrost thermistor’) and cost £10–£25. Unplug the old one and clip the new one in place — no soldering required on most models.
If the thermistor tests fine, do not attempt to replace the defrost heater or thermal fuse yourself — these require safe multimeter testing and component-level knowledge. Call a qualified appliance engineer at this stage.
📞 When to call a professional
Call an appliance engineer if the E7 code returns after a manual defrost, or if you’ve replaced the thermistor and the fault persists — the defrost heater, thermal fuse, or PCB will need professional diagnosis. When booking, tell the engineer: ‘My Hotpoint fridge is showing an E7 error code, which I understand relates to the defrost circuit — I’ve already manually defrosted it and the fault has returned.’
⚖️ Repair or replace?
A professional repair for an E7 fault typically costs £80–£150 in the UK, covering call-out, parts (thermistor, heater, or fuse), and labour. If your Hotpoint fridge is under 8 years old, repair is almost always the better financial choice. For fridges over 10 years old, or if the PCB needs replacing (adding £80–£130 to the bill), a new fridge-freezer from £300–£500 may make more sense long-term.
