Fridge
E6
The E6 error code on a Hotpoint fridge signals a fault with the defrost sensor or defrost circuit — it’s a moderate fault that won’t fix itself and needs prompt attention to prevent food spoilage and compressor damage.
What does this error mean?
The E6 code indicates that the fridge’s control board has detected an abnormal reading from the defrost temperature sensor (sometimes called the defrost thermistor). This sensor monitors the evaporator coil temperature during the automatic defrost cycle. When the reading falls outside the expected range — either open circuit, short circuit, or out-of-range temperature — the board logs E6 and may suspend normal defrost cycles, leading to ice build-up on the evaporator and reduced cooling performance.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and reset: Unplug the fridge for 10 minutes, then plug it back in. A transient fault can trigger E6; a full reset clears stored errors and costs nothing.
Check for ice build-up: If the fridge is cooling poorly, manually defrost it. Remove all food, unplug the unit, leave the doors open, and place towels on the floor. Allow 24–48 hours for all ice to melt naturally — never use a heat gun or sharp tools. This alone can resolve sensor misreadings caused by ice blockage.
Inspect the evaporator cover and wiring: Once defrosted, remove the back panel inside the freezer or fridge compartment (usually clipped in place — no tools required on most Hotpoint models). Visually check the wiring connector to the defrost sensor for corrosion, moisture, or a loose plug. Firmly reseat any loose connectors.
Test or replace the defrost thermistor: The thermistor is a small sensor clipped to the evaporator coil. Replacement parts for Hotpoint models (e.g. C00143526 or equivalent) cost £8–£20 on sites like eSpares or Hotpoint’s own parts store. Unclip the old sensor, unplug its connector, and clip the new one in place — no specialist tools needed.
Replace the defrost heater element if needed: If a continuity test (using a basic multimeter set to resistance) shows the heater element is open circuit (no continuity), the element needs replacing. This is a straightforward part swap but requires comfort working around internal fridge components — if in doubt, stop and call a technician.
If the error persists after all of the above, do not attempt to repair or replace the main PCB yourself — this requires professional diagnosis.
📞 When to call a professional
Call a qualified appliance engineer if the E6 error returns after a manual defrost and thermistor replacement, or if you find burnt wiring, scorched components, or a suspected PCB fault. When booking, tell the engineer: ‘My Hotpoint fridge is displaying error code E6 — I suspect a defrost sensor or defrost heater fault.’ This helps them bring the right parts and reduces call-out time.
⚖️ Repair or replace?
A professional repair for an E6 fault typically costs £80–£150 including parts and labour (thermistor or heater element replacement). If the main PCB is at fault, repair costs can rise to £150–£220, at which point replacement becomes worth considering. As a rule of thumb, if your Hotpoint fridge is over 8–10 years old and the repair quote exceeds half the cost of a new equivalent model, replacing it is the more economical long-term choice.
