When turning on the equipment by turning the main button on the Control check card, the equipment does not start, neither the brush motors nor the suction motor, even if the white LED on the Control check card lights up. In the video you will see exactly what happens. After replacing the Power check card, the equipment worked but stopped immediately because of the residual water sensor. After replacing the sensor, the equipment works without problems. No traces of water or aggression can be seen on these replaced parts. In conclusion, the defective parts of this equipment are: Power check card and residual water sensor.
Unfortunately TSM-Spare-parts-manual-WILLMOP-50_IT-EN-FR-DE-ES_2021.pdf the one I have and the one that can be downloaded from your website is not updated, so I don’t know what the code is for Power check card, the new version of equipment.
