Frequently Asked Questions

Can I keep using my Electrolux Washing Machine when error E21 appears? +
It is not advisable. The washing machine may still power on, but running it while E21 is active can worsen the drainage fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes E21 on a Electrolux Washing Machine? +
Across reported Electrolux washing machine repairs, the most frequent is pump filter clogged (50% of cases), drain hose kinked or blocked (25%), then standpipe restricted (15%). Check them in that order before replacing any parts.
E21 keeps coming back after a reset — what should I check next? +
A reset only clears the stored E21 fault; if it returns, the drainage problem is still present. Move on to the physical checks — clean the pump filter, then check the drain hose and standpipe — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Electrolux Washing Machine error E21? +
A DIY repair typically runs $0–$90 in parts, versus $150–$280 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.
