Freezer
E5
The E5 error code on a Hotpoint freezer indicates a fault with the evaporator temperature sensor (NTC sensor), meaning the appliance cannot accurately read its internal temperature. It’s a moderately serious fault — your freezer may struggle to maintain safe freezing temperatures, so act promptly.
What does this error mean?
The E5 code signals that the freezer’s evaporator NTC (Negative Temperature Coefficient) sensor has sent a reading outside the expected range — typically because it has failed, become disconnected, or is reading incorrectly due to heavy ice build-up. The evaporator sensor monitors the temperature of the cooling coils; without a reliable reading, the control board cannot regulate the compressor and fan correctly. In some Hotpoint models, E5 can also appear after a prolonged power cut or when the appliance has been switched off and restarted before it has fully stabilised.
Est. repair cost
£80–£130 for NTC sensor replacement (professional); £15–£30 DIY sensor part only. PCB replacement: £120–£200+ professional.
🔍 Likely causes
🛠️ Step-by-step fix
Reset the freezer: switch it off at the wall, wait 10 minutes, then switch it back on. If E5 clears and does not return within a few hours, the fault was a temporary sensor glitch.
Check for heavy ice build-up: if the freezer interior or back panel feels unusually thick with ice, switch the appliance off and perform a full manual defrost (leave the door open with towels on the floor for 12–24 hours). Restart and check if E5 returns.
Inspect the door seal: a damaged or ill-fitting door gasket lets warm, moist air in, causing excessive icing that can trigger E5. Press the seal firmly around the frame — replace it if you feel gaps or see cracks (replacement seals cost £10–£25 online for most Hotpoint models).
Check the evaporator fan (usually behind the rear interior panel): listen for the fan running when the freezer is on. If it is silent or making a grinding noise, the fan motor may have failed and will need replacing — this is a DIY-feasible job if you are comfortable removing the interior back panel, but call a professional if you are unsure.
Inspect wiring connectors: if you can safely access the evaporator area after defrosting, check that the sensor wiring connector is firmly pushed home and shows no signs of corrosion or burn marks. Reseat any loose connectors. Do not open any sealed electrical components.
If none of the above resolves E5, the NTC sensor itself or the PCB has likely failed and will need professional diagnosis and replacement.
📞 When to call a professional
Call a qualified appliance engineer if the E5 code returns after a full defrost and reset, or if you suspect a wiring, sensor, or PCB fault. When you call, tell the engineer: ‘My Hotpoint freezer is displaying an E5 error code — I believe it relates to the evaporator NTC temperature sensor.’ This will help them bring the right parts. Do not attempt to replace the PCB yourself — this involves working with mains-voltage components.
⚖️ Repair or replace?
An NTC sensor replacement typically costs £80–£130 for a professional call-out including parts; a PCB replacement is more expensive at £120–£200+. If your Hotpoint freezer is under 7 years old, repair is usually worth it. If it is 8 years or older and the PCB has failed, a new freestanding freezer starts from around £180–£250, making replacement the more economical choice.
