[Solved] Electrolux WSL4575RO Dishwasher - Error i50: Troubleshooting Motor, Triac & Warranty Issues

Hello,
The dishwasher after about half a year showed an error I50 (unfortunately I can not take advantage of the warranty despite the new equipment), I took off the covers all dry. According to information found on the forum, the error appears when the main engine is running at max. speed. Tomorrow I will dismantle the motor and check all contacts, apparently the reason may be a triac on the plate or is this plate in the motor at its back (black housing)? You have to dismantle the engine to get to it?
Thank you in advance for the information...

Are you sure this is an i50 error? The displayed code is not an error code.

In this dishwasher, the user only displays the start code of the alarm group, so i50 means that the error belongs to this group of errors - this is not the designation of the error code itself, it means nothing. To be able to find out the last remembered error code, enter service mode - a welcome service for repairing this dishwasher.
i50 is the information that should be given to the service called to repair the dishwasher.
After a new series dishwasher is repaired, always carry out - LEDTest and LineTest .

PS A new innovative equipment has been encouraged. Most likely, this year, and certainly next year, error codes in new models of home appliances can only be deleted using the service interface. Simple inverter repair will not be possible, very difficult.

I50 so shows PNC 911 074 010 01

The whole i5x litany of errors is related to:
- current measurements on an asynchronous motor
- Vbat voltages
- short circuit on engine
- MCU failure
- DCLink or Vbat voltage measurements of the analog-to-digital converter

The Vbat voltage is used to measure motor resistance

For example, several errors of the i50 group (the meaning of the error code depends on the software platform - various damage symptoms on different software platforms):

i58 - An alarm occurs when, based on current measurement, it remains
incorrect motor connection detected. If the current does not exceed the set range (+/- 21 mA), a reflection time of 1.5 s is set
- An alarm with this code can also occur after a phase loss or damage to the motor winding

i5A
o An internal warning appears when, based on internal calculations, an exceeded standard temperature limit is detected based on the measured current values (200 ° C with a 40-degree margin due to the measurement method and calculation tolerances).
o The warning threshold is 200 - 70 (max. Temperature inside the dishwasher) - 10 (activation margin) = 120 ° C. The warning level is given.
o If a warning occurs, the motor stops and a new winding resistance calculation is made. In this way, the actual temperature can be calculated - the temperature calculation is based on the reference winding resistance of the motor at 22 ° C.
- an alarm is generated when the value is higher than the threshold value of 178 ° C (200 - 22).
It should be remembered that the alarm is reset by the MCB after verification by the main electronic system.

i5B
o An alarm occurs if the current level does not change within 2.5 s less than 0.0275 A for the washing pump.
o An alarm occurs if the current level does not change within 0.5 s less than 0.03363 A with an emptying pump.
o On a 7-segment display "B" can be displayed as "H"

I repeat the displayed errors, among others dishwashers type i10 i20 i30 i40 i50 i60 are not error codes. The dishwasher informs us from which group the error was saved to the processor's memory. The error code can be read after entering the service mode.

And how to enter the service mode to read what exactly could have broken?

This is a question for Electrolux. Such information cannot be given without the consent of Electrolux Polska.
I'm sorry. If you call a competent service - it will repair your dishwasher.
The policy of companies including Whirlpool or Electrolux has changed - in a word, the era of "extermination" of self-repairers is slowly entering.

You have enough tips to repair this dishwasher without problems - as long as you have the right knowledge.

There is also such a symptom that when I start it, it can be heard as if a relay tried to switch something on (popping) after a few attempts, an error turns on and 5 beeps (i50). Maybe this is something I will direct and you will give me more tips I will try next week to fail a website.

I bought because of the low operating costs, although they said in the store that it is not the same quality as they used to be, I have an older model from 15 years so far I replaced the heater and the door seal last year, and so trouble-free. Somehow I lost both the card and the receipt, I have only instructions.

I will be grateful for any hints.

Can the reason be a three-way valve, or is it unlikely after the error code? I checked the pump's asynchronous motor, there is no breakdown, two were not connected for a short time because the motor has information that the input voltage is 200V, is it possible or just a Chinese sticker error?

Hello
Go to the store where you bought the equipment and give them a copy of the receipt / invoice.

Thank you for specific advice on the electronic forum that I also did not think to remember, having no documents, which March or April I bought the equipment or in the store where the cash register itself (there is no computer system) will find a receipt from the cash register for a period of 2 months. I needed such advice ...

Dude, can you describe how this story ended? I have identical symptoms in Electrolux ESL8336RO - I lost 11 days after the warranty period

thanks

Hello.
Ultimately, the warranty replaced the entire module with motor and pump

Hello, how did your story end? I have the same problem...
Thank you

Hello. The problem with the i50 error is as follows. First remove the washing pump and check that there is no axial play. Before disassembling anything, turn on the test (calibration ///) and check that and 50 is always turned on at the same time for about 5 minutes on the display. If so, remove the pump.

I pulled out the pump (in the middle of the dishwasher the white round one. It unscrews to the left.) There was a string wound on the axle and a piece of glass in the channel above. I reassembled. There was an i30 error, as water came off the channel. I sponged the water out and switched it on. It pumped the water in and started.

At my place I changed the wash pump, it looked ok, winding also ok, perfect. I've been twice to buy a new pump as the cost is £370 and if it turns out not to be the culprit, £379 remains lost.
After replacing it, the dishwasher came to life.
