Water fountain not flowing? Pump cleaning is a quick diagnostic step that resolves many flow problems. It does not replace quality support when a defect is suspected.
Model finder

Look for a model number beginning with letters and numbers, such as D2650 or D2419. If no model is visible, compare the product image in your order details and keep the order number ready when contacting support.
- Check the label on the product base or housing.
- Check the power adapter, packaging, or instruction card.
- Use the product image and model shown in your order details.
