FAQ
TL;DR: i50 on Electrolux means a motor/drive fault group, not a specific code; "i50 ... are not error codes." Typical thresholds include b121 mA and 1.5 s. Read the stored code in service mode, then inspect the wash pump and wiring. [Elektroda, Piotr2608, post #17153769]
Why it matters: This FAQ helps Electrolux ESL/WSL owners diagnose i50 group faults, decide next steps, and talk to service clearly.
Quick Facts
- i50 is a group indicator; read the last stored code in service mode, and newer models clear codes only via the service interface. [Elektroda, Piotr2608, post #17153211]
- i58: motor-current window b121 mA with 1.5 s reflection time; may indicate phase loss or winding damage. [Elektroda, Piotr2608, post #17153769]
- i5A: thermal model warns near 120 b0C and alarms at 178 b0C; based on 200 b0C limit and 22 b0C reference. [Elektroda, Piotr2608, post #17153769]
- i5B: current must change within 2.5 s (>0.0275 A, wash pump) or 0.5 s (>0.03363 A, drain); "B" can show as "H". [Elektroda, Piotr2608, post #17153769]
- Quick triage: during calibration, if i50 recurs around 5 minutes, remove the wash pump and check axial play. [Elektroda, xeroxhp1, post #19114060]
What does the i50 error actually mean on Electrolux WSL/ESL dishwashers?
It flags the i5x alarm group, not a specific code. The group covers motor current sensing, Vbat voltage, engine short, MCU fault, and DCLink/Vbat ADC issues. "Displayed errors i10...i50 are not error codes; the dishwasher shows the group." Read the exact stored code in service mode. [Elektroda, Piotr2608, post #17153769]
How do I read the exact stored error code when i50 appears?
Enter the dishwasher’s service mode to read the last stored error code. The user display only shows the alarm group (i50), not the code. Use that code to guide targeted repair steps. Electrolux recommends this for proper diagnosis and service. [Elektroda, Piotr2608, post #17153211]
What do i58, i5A, and i5B mean within the i50 group?
i58: incorrect motor connection by current measurement ( b121 mA window, 1.5 s). i5A: thermal model warnings near 120 b0C and alarm at 178 b0C; recalculates winding resistance vs 22 b0C reference. i5B: current must change within 2.5 s (>0.0275 A, wash pump) or 0.5 s (>0.03363 A, drain). Edge case: "B" can appear as "H" on 7‑segment. [Elektroda, Piotr2608, post #17153769]
How can I quickly triage an i50 at home?
Try this brief check during the dishwasher’s calibration/test. 1. Start the test and watch the elapsed time. 2. If i50 repeats near the 5‑minute mark, suspect the wash pump. 3. Remove the wash pump and check for axial play before further work. [Elektroda, xeroxhp1, post #19114060]
What should I inspect on the washing pump for i50-related issues?
Remove the wash pump and check for axial play at the shaft. Excess play suggests mechanical wear or obstruction. Correlate with calibration timing: if i50 appears consistently around five minutes, focus on the pump. Replace or service the pump if play or binding is present. [Elektroda, xeroxhp1, post #19114060]
I hear relay clicking and then five beeps before i50. Is that a known pattern?
Yes. A user reported repeated relay “popping,” followed by five beeps and then i50. Document this sequence and any timing for service. Use calibration to reproduce if needed, and gather details for a technician’s diagnosis. [Elektroda, macwita, post #17154140]
Can debris in the pump cause startup failures related to i50?
Yes. One user removed the center white round pump, found a string on the axle and glass in the channel, reassembled, then cleared water from the tray after an i30 leak alarm. The dishwasher then filled and started normally. [Elektroda, Pares1, post #21313412]
Could a three‑way valve cause an i50 fault?
Unlikely. The i5x group maps to motor current measurement, Vbat measurement, engine short circuit, MCU failure, and DCLink/Vbat ADC issues. These target the motor/drive electronics rather than a diverter valve. Focus on motor, wiring, and control. [Elektroda, Piotr2608, post #17153769]
What is Vbat here, and why does it matter for i50?
Vbat is a supply rail used by the controller for measurements. The system uses Vbat to measure the motor’s winding resistance. Faults in Vbat measurement or ADC interpretation fall under the i5x group. This affects temperature estimation and protection logic. [Elektroda, Piotr2608, post #17153769]
Can I clear the i50 error without the official service interface?
On newer models, error codes can only be deleted using the official service interface. "Error codes in new models... can only be deleted using the service interface." Plan on service access to clear codes after repairs. [Elektroda, Piotr2608, post #17153211]
What should I run after repairing an i50‑related fault?
Run the built‑in diagnostics: LEDTest and LineTest. These confirm electronic and line conditions after module or motor work. “After a new series dishwasher is repaired, always carry out LEDTest and LineTest.” Record results for future reference. [Elektroda, Piotr2608, post #17153211]
What ultimately fixed the original poster’s dishwasher?
Service replaced the entire module with the motor and pump under warranty. That resolved the symptoms associated with the i50 group. This path is common when the drive electronics and pump bundle are implicated. [Elektroda, macwita, post #17696049]
I lost my receipt. Any warranty options left?
Return to the store where you bought the dishwasher and request a copy of the receipt or invoice. Provide the purchase date window and product details. The store may retrieve documentation for warranty support. [Elektroda, zibi1971, post #17163209]
