Washing Machine
E70
The E70 error code on an Electrolux washing machine signals a problem with the appliance’s heating circuit — specifically, the machine cannot verify that the water is heating correctly. It’s a mid-level fault: your machine won’t complete a wash cycle until it’s resolved, but it doesn’t pose an immediate safety risk.
What does this error mean?
E70 indicates that the washing machine’s control board has detected a fault in the heating system — either the heater element isn’t activating, the temperature sensor (NTC thermistor) isn’t reporting correctly, or there’s a wiring break in the heating circuit. Essentially, the machine starts to heat the water, checks whether the temperature is rising as expected, and when it doesn’t see the right result within a set time, it throws the E70 code and stops the programme. This is a protective measure to prevent cold washes or damage from a continuously running but non-functioning heater.
Est. repair cost
DIY element or thermistor swap: £15–£40 for parts. Professional repair: £80–£150 for element/sensor; £150–£250+ if PCB replacement is needed.
🔍 Likely causes
🛠️ Step-by-step fix
Reset the machine first: switch it off at the wall, wait 2 minutes, then power it back on and try a hot wash (60°C). A one-off glitch can clear this way.
Run a descale cycle: if you’re in a hard-water area and haven’t descaled in over 6 months, use a proprietary washing machine descaler (e.g. Calgon or own-brand equivalent) on an empty hot cycle. Limescale on the element is a common trigger.
Check the filter and drainage: a blocked pump filter can cause the machine to stall and log heating errors indirectly. Locate the filter (bottom-right panel on most Electrolux models), drain the water using the small hose, then unscrew and clean the filter.
Inspect the heating element resistance: if you’re comfortable with a multimeter and have unplugged the machine at the wall, you can remove the back panel, locate the element at the bottom of the drum, disconnect its terminals, and test resistance. A healthy element typically reads 20–30 ohms; an open circuit (OL/infinity) means it’s blown. Only proceed if you are confident working around electrical components — if in doubt, stop here.
Replace the heating element yourself: compatible Electrolux elements cost £15–£35 online (search your model number, found inside the door rim). This is a straightforward DIY repair — unplug the machine, remove the back panel, unclip the element, swap it, and reassemble. Dozens of model-specific YouTube tutorials are available.
If the element tests fine, the NTC thermistor is the next suspect — it’s a small sensor clipped near the element, usually costs £8–£20, and is equally straightforward to replace once the back panel is off.
📞 When to call a professional
If you’ve replaced both the heating element and NTC thermistor and the E70 code persists, the fault likely lies with the wiring loom or the main PCB — both of which require a qualified appliance engineer to diagnose safely. Call an engineer and tell them: ‘My Electrolux washing machine is showing error code E70, I’ve already replaced the heating element and thermistor, and I suspect a wiring or PCB fault.’ This saves diagnostic time and cost. Also call a professional if you’re not confident isolating the appliance from the mains before opening any panels.
⚖️ Repair or replace?
A heating element replacement by a professional typically costs £80–£140 all-in for parts and labour in the UK — well worth it if your machine is under 8 years old and otherwise in good condition. If the PCB is at fault, repair costs rise to £150–£250+, at which point a machine over 7–8 years old may not justify the spend. As a rule of thumb: if the repair quote exceeds 50% of a new equivalent machine’s price, replace it.
