Using this Whirlpool lid switch is straightforward. First, make sure your washing machine is unplugged for safety. Locate the old lid switch and carefully remove it. Then, attach the new switch using the 25mm - apart mounting holes. Connect the 3 - pin connector with round pins to the appropriate place. The total length of the wiring and plug is 70cm, so you should have enough reach. When using your washing machine, just close the lid as usual, and the switch will do its job. As for maintenance, keep the switch dry and clean. If you notice any issues like the switch not working properly, don't try to fix it yourself. Instead, contact our customer service. Remember, this product is fully guaranteed, so you can rely on us for support.
