Washing Machine
E62
The E62 error code on an AEG washing machine indicates the water is overheating during a wash cycle — a fault that will stop the machine mid-programme to prevent damage. It’s a moderately serious error that needs attention before you run another cycle.
What does this error mean?
E62 means the washing machine’s internal temperature sensor (NTC thermistor) has detected water temperature exceeding the expected threshold for the selected programme — typically above 90°C when it shouldn’t be. The machine cuts out as a safety measure. This is distinct from E61 (no heating) — E62 is specifically the machine getting too hot, not too cold.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 – Reset the machine: Turn the washing machine off at the socket, wait 5 minutes, then power it back on. Select a cold wash (30°C) and run a short cycle to see if E62 reappears. A one-off glitch can sometimes clear itself.
Step 2 – Check for limescale: If you live in a hard water area (most of the Midlands, South East, and East of England), heavy limescale on the heating element can cause erratic temperature behaviour. Run a monthly 60°C maintenance wash with a proprietary descaler such as Calgon to keep the element clear.
Step 3 – Inspect the wiring harness (visually only): Pull the machine away from the wall and check the back panel for any obviously scorched, kinked, or disconnected external wires. Do not open the machine casing — any internal inspection requires a qualified engineer.
Step 4 – Test the NTC thermistor resistance (if you own a multimeter): After disconnecting the machine from power, an engineer or confident DIYer can access the thermistor (usually clipped to the drum casing). A healthy NTC thermistor on AEG machines typically reads around 5kΩ–10kΩ at room temperature. A reading of 0Ω or OL (open line) confirms a faulty sensor. Replacement thermistors cost £10–£25 on PartMaster or eSpares.
Step 5 – Replace the NTC thermistor if confirmed faulty: Disconnect the two-pin connector, unclip the old sensor, fit the new one, and reconnect. This is a straightforward DIY task on most AEG front-loader models once the top panel is removed. Always disconnect from mains power first and ensure the machine is fully unplugged before touching any internal components.
Step 6 – If the error persists after a thermistor swap: The fault is most likely the heating element, triac, or PCB — stop DIY attempts and book a repair engineer. These components involve mains voltage and are not safe for unqualified repair.
📞 When to call a professional
Call a qualified appliance repair engineer if the error returns after a reset and descale, or if the thermistor tests fine but the fault persists — this points to a faulty heating element, triac, or PCB, all of which involve mains voltage components. When booking, tell the engineer: ‘My AEG washing machine is displaying error code E62 — I believe it’s an overheating or temperature sensor fault.’
⚖️ Repair or replace?
A thermistor replacement is a low-cost DIY fix (£10–£25 in parts). A professional repair covering thermistor, heating element, or PCB work typically costs £80–£160 including labour. If your AEG machine is over 8 years old and requires a PCB or heating element replacement, weigh repair costs against a new machine — budget AEG models start around £400, and a repair bill over £150 on an older machine is often not economical.
