iF0 or iF1 on the ESF68020 means the control has detected overfilling or excessive water-management time; foam can imitate too much water. Confirm the visible symptom before resetting; filters, loading, detergent, water supply and door alignment are safe checks, internal wiring is not. Hand-dish soap, excessive automatic detergent or an abnormal fill can raise foam or level until the protection stops the programme. Photograph the code and look for foam without opening panels. iF0/iF1 differs from i30 leak protection even if the appliance drains. Cancel, close the water valve, let foam settle and remove dishes. Use no detergent while running the official rinse sequence; never add products to neutralise foam unless Electrolux directs it. Use correct automatic detergent for one empty test only after foam is gone. If iF0/iF1 returns or filling continues abnormally, close the valve and request service.
Models covered
Safety first
- Cancel, switch off, close the water valve and let hot dishes cool. Wear gloves near the filter; never tilt a built-in appliance or remove its base or side panels.
What the symptom may indicate
Checks in the right order
- Confirm before acting
Hand-dish soap, excessive automatic detergent or an abnormal fill can raise foam or level until the protection stops the programme.
- Make the appliance safe
Cancel, switch off, close the water valve and let hot dishes cool. Wear gloves near the filter; never tilt a built-in appliance or remove its base or side panels.
- Apply the official check
Cancel, close the water valve, let foam settle and remove dishes. Use no detergent while running the official rinse sequence; never add products to neutralise foam unless Electrolux directs it.
- Retest once and decide
Use correct automatic detergent for one empty test only after foam is gone. If iF0/iF1 returns or filling continues abnormally, close the valve and request service.
Stop and get qualified help when
- Stop for water in the base, an uncontrolled leak, heat or motor code, burning smell, damaged cable or a fault that returns after one empty test.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
