If you see ‘LR’ on the display, the control board is not detecting the motor’s work.
Please, see the wiring diagram below (posted upon your requests).
It should be noted that the error code appears when the main control board has tried to get the motor to turn, but could not do it.
The motor could have gotten blocked due to an overload, excess suds, or a fault in its mechanism (faulty spin bearing). Please, see how often the error code appears and check these factors.
