Using this Vulcan Dishlex Fast Wash Switch is straightforward. Just find the right spot in your dishwasher where the old switch was located and install the new one. It's designed to fit easily. When installing, if you're replacing a white or coffee - coloured switch and want to keep the original look, remember to transfer the cap from the old switch. As for maintenance, keep the switch clean and dry. Avoid getting water directly on it as this could damage the internal components. If you notice any issues like the switch not working properly or the neon indicator not lighting up, check the connections first. If the problem persists, contact our support team. We offer a full guarantee, so you can be confident in using this product for your dishwasher.
