What Does Error Code i20 Mean on a Electrolux Dishwasher?

Drain fault — clogged filter or blocked drain path.

The i20 code (and its i40/iF0 variants) fires when the control board detects that water remains in the tub after the drain pump has run for its expected time, based on feedback from the water-level sensor. Rather than a pump-electrical fault, it flags an incomplete drain — most often restricted flow through a clogged filter, kinked or blocked drain hose, or debris caught in the pump impeller. This distinguishes it from fill-related i-codes, which fault on inadequate water entering the tub.

Models affected: Electrolux dishwashers displaying i-series diagnostic codes, including built-in models such as the EI24ID30QS, and other integrated units using this control platform
What owners report: Owners commonly report i20 appearing near the end of a cycle with standing water left in the tub, and many find a quick filter clean-out resolves it. False triggers can follow a new installation where the drain hose is kinked behind the unit or lacks a proper high loop.

Frequently Asked Questions

Can I keep using my Electrolux Dishwasher when error i20 appears? +
It is not advisable. The dishwasher may still power on, but running it while i20 is active can worsen the drainage fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes i20 on a Electrolux Dishwasher? +
Across reported Electrolux dishwasher repairs, the most frequent is clogged filter assembly (40% of cases), blocked or kinked drain hose (30%), then food debris in the drain pump (20%). Check them in that order before replacing any parts.
i20 keeps coming back after a reset — what should I check next? +
A reset only clears the stored i20 fault; if it returns, the drainage problem is still present. Move on to the physical checks — clean the filters, then check the drain hose — 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 Dishwasher error i20? +
A DIY repair typically runs $0–$95 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.
Which Electrolux Dishwasher models show error i20? +
i20 is documented on Electrolux dishwashers displaying i-series diagnostic codes, including built-in models such as the EI24ID30QS, and other integrated units using this control platform. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
