Error codeEr16

Affected model seriesEIDW6105, EIDW5905
Quick answer
Electrolux dishwasher code Er16 indicates float switch is stuck or the drain path is clogged.
Model compatibility: Electrolux reuses codes across series and control generations, so Er16 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Electrolux dishwasher code Er16 points to float switch is stuck or the drain path is clogged. The display narrows the diagnostic path, but it does not prove which component should be replaced. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
This display is most useful when it is paired with the model number and observed behavior: float switch is stuck or the drain path is clogged. The same display can accompany dishwasher may refuse to fill, so the next step is to rule out float switch stuck before moving deeper into drain restriction.
This code is documented in Electrolux EIDW6105/EIDW5905 service data. Confirm the exact model before applying this diagnostic path.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Clean accessible filters and the sump.
Check the external drain hose for restriction.
Make sure no obvious debris is preventing normal float movement if the float is user-accessible.
Try one restart after correcting an external drain issue.
Important safety warning. Stop if there is water in the base pan or active leaking.

When to call a technician
Book repair if Er16 returns because internal float and drain components may need testing.
If Er16 returns, give the technician the exact model number, the code exactly as shown, and whether dishwasher may refuse to fill. That information helps focus testing on float switch stuck and related platform-specific circuits.

It indicates float switch is stuck or the drain path is clogged. Confirm the full model number because Electrolux diagnostic meanings can vary between control platforms.
You can try the safe external checks on this page and one power reset when appropriate. If the code returns, repeated resets are not a substitute for diagnosis.
Avoid repeated cycles if the float condition persists, especially if water is present in the base pan.
