FAQ
TL;DR: Electrolux i50 flags wash‑pump faults; i53 triggers above 1.3 A—"Two strokes of the meter are enough." This FAQ helps ESL6374RO/ESL74561RO owners quickly diagnose and fix i50/i53 without guessing. [Elektroda, Piotr2608, post #17539014]
Why it matters: Fast, targeted checks get your dishwasher running again and avoid unnecessary parts swaps.
Quick Facts
- i50 relates to the wash pump; i53 is brushless-motor overcurrent, with a 1.3 A maximum permitted current. [Elektroda, Piotr2608, post #17539014]
- Intermittent pump starts do not confirm health; check the main pump circuit and the pump itself. [Elektroda, Chupacabra, post #17526963]
- Control module location: remove the right side cover; bottom corner by the power cord, in a plastic case. [Elektroda, qwazarpl, post #18190649]
- i50 can appear at the start, mid-cycle, or end; hydrostat cleaning alone may not resolve it. [Elektroda, GrzesiekF1, post #17529647]
- Edge case: worn pump bearings can make the impeller rub, raise current, and trigger i50. [Elektroda, ElChupacabra, post #18945195]
What does Electrolux dishwasher error i50 mean?
i50 points to the wash-pump path. It indicates a fault in the circulation pump or its drive. Focus diagnosis on the washing pump and its supply path before suspecting other systems. [Elektroda, Piotr2608, post #17539014]
What does service code i53 mean on ESL6374RO?
i53 means the brushless motor overcurrent threshold tripped. The controller reports i53 when measured current exceeds the permitted 1.3 A. "Two strokes of the meter are enough." Measure the motor current under load and compare to that limit. [Elektroda, Piotr2608, post #17539014]
Can a pump that sometimes starts still be bad?
Yes. Intermittent starting does not prove the pump and its circuit are healthy. Check the main pump circuit, connectors, and the pump itself even if it occasionally runs. [Elektroda, Chupacabra, post #17526963]
Why does i50 pop up randomly even after cleaning the hydrostat?
Users report i50 still appearing randomly at the beginning, during, and at the end of cycles after thorough hydrostat cleaning. That pattern suggests causes beyond the hydrostat, such as the wash pump or its control. [Elektroda, GrzesiekF1, post #17529647]
My ESL6374RO ran five cycles after module repair then failed again—what now?
Intermittent faults can pass several runs before returning. One owner saw five normal cycles, then i50 returned and i53 appeared in service mode. Continue diagnosis on the motor/pump path and connections to isolate the recurring issue. [Elektroda, adaszc0489, post #17538667]
Where is the control module/triac board located on these Electrolux models?
Remove the right side cover. The control module sits at the bottom corner near where the power cord enters, inside a plastic case. This location lets you observe operation during tests. [Elektroda, qwazarpl, post #18190649]
Should I hunt for "thyristors" on the board?
Do not fixate on finding “thyristors.” "Good luck finding thyristors ...." Start by checking whether the wash pump is physically blocked by a foreign object instead. Clear obstructions before deeper board work. [Elektroda, Anonymous, post #18189985]
How can I check if the wash pump is running or just humming?
With power disconnected, remove the right side cover. Restore power, start a cycle, and watch or listen to the pump. "God forbid, while working, don't put your hands there!" Stop immediately if you hear humming without rotation. [Elektroda, qwazarpl, post #18190649]
Could worn pump bearings trigger i50?
Yes. A worn bearing can let the impeller rub the housing, increasing current draw and tripping i50. Inspect for shaft play and scraping marks if i50 occurs during circulation. Replace or rebuild the pump if wear is found. [Elektroda, ElChupacabra, post #18945195]
Do wiring issues in the door cause i50 or mixed errors?
They can. Inspect the door wiring harness for breaks or chafing that could intermittently disrupt signals or power. Repair any damaged conductors or insulation before replacing parts. [Elektroda, Anonymous, post #17532473]
Does cleaning the hydrostat resolve i50?
Not necessarily. One report shows i50 still triggered randomly, even after thorough hydrostat cleaning. That indicates the root cause often lies elsewhere, such as the wash pump or its drive. [Elektroda, GrzesiekF1, post #17529647]
What should I check first when i50 appears?
Start with the main pump circuit and the pump assembly. Verify connectors, wiring, and pump freedom of movement. Intermittent starts are not proof of a healthy pump. [Elektroda, Chupacabra, post #17526963]
How do I quickly diagnose an i53 overcurrent event?
- Access the motor circuit safely and prepare a meter.
- Run a wash phase and measure the motor/pump current.
- If current exceeds 1.3 A, investigate pump drag or motor faults; repair and retest. "Two strokes of the meter are enough." [Elektroda, Piotr2608, post #17539014]
