Hello, did your colleague solve the problem? I got an identical dishwasher with an i40, i20 error battery and the i50. After thorough cleaning of the hydrostat and it was still i50 (in the i53 service mode) popping up randomly - and at the beginning, and during and at the end ...

Check the wiring of the wiring harness in the door

Hello again, after examining and repairing the module from the engine by the electronics, the dishwasher worked 5 times normally until the next time when the i50 error appeared again, but this time, after entering the service mode, the i53 error appeared. Do you have any idea what this error will be related to this time, so I know that with the engine or module again?

I don't understand this - why do you enter service mode if you can't use it? The i50 errors are related to the failure of the washing pump and the i53 error means: - brushless electric motor - overcurrent The error occurs when the detected current is greater than the maximum permitted and the set maximum permitted current is 1.3 A Two strokes of the meter are enough to identify the cause.

Hello, I have the same problem with the Electrolux ESL74561RO dishwasher. It keeps showing i50 error. after unscrewing the underside of the dishwasher, I did not notice anything disturbing. Could someone tell me where to look for the module with the board, where are thyristors that are probably the cause of the error? I will be grateful for the information. Sebastian

Good luck finding thyristors .... First, check that the pump is not blocked by any foreign object

I will check and I will get information where the triac module is?

Remove the right cover of the dishwasher. At the bottom in the corner you will see a module in a plastic case. Where you plug in the power cord, there is a module. Before you start looking for a fault in the module, turn on the dishwasher with the right side dismantled and watch, listen to whether the washing pump is working or standing and humming. God forbid, while working, don't put your hands there!

Thank you for your specific answer. I will let you know if I can remove the fault.

Hello, the problem is with the Electrolux ESL6374RO dishwasher.
Namely, the dishwasher, after switching on the program, releases the water, then it pours as it should and then pops up i50 error I will also add that the washing pump works because this error will not appear every time, and when the washing pump starts, the program works smoothly and without problems until the end. I was looking at other posts related to it and that's why I'm writing because should I look for this error in the module or at the engine? I will add photos of the module.

The i50 errors are related to the failure of the washing pump and the i53 error means:
- brushless electric motor - overcurrent
The error occurs when the detected current is greater than the maximum
permitted and the set maximum permitted current is 1.3 A

Two strokes of the meter are enough to identify the cause.

Hello, I have the same problem with the Electrolux ESL74561RO dishwasher. It keeps showing i50 error. after unscrewing the underside of the dishwasher, I did not notice anything disturbing.
Could someone tell me where to look for the module with the board, where are thyristors that are probably the cause of the error?
I will be grateful for the information.

How would it help someone, the cause of the i50 error in this dishwasher may still be, just like my bearing in the washing pump, the impeller began to rub against the body and hence the increase in the pump current and the i50 error.

I also have a problem with worn plain bearings, what should be the clearance between the shaft and the bearing slide, it works on the water seal, so there must be a gap - what kind. I will add such bearings, I just need to know what dimension to make in relation to the shaft.

Topic summary

✨ The Electrolux ESL6374RO dishwasher is experiencing intermittent i50 error codes, which may indicate issues with the washing pump or the control module. Users suggest checking the main pump circuit and wiring harness, as well as the pump for blockages or bearing wear. The i50 error is often linked to pump failure, while the i53 error indicates overcurrent in the brushless electric motor. One user reported that after module repairs, the dishwasher initially functioned correctly before the error reappeared. Another user with a similar model, ESL74561RO, also encountered the i50 error and sought guidance on locating the module and potential causes. Recommendations include inspecting the pump and module, and ensuring no foreign objects obstruct the pump's operation.

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]
