What to do if my Xylem Water Pump is not running?
If your Xylem Water Pump isn't running, there could be several reasons. First, check if it's properly connected. If the pump is too hot due to dry operation or overheating protection, allow it to cool down; it should restart automatically. Finally, the pump might be blocked.
Why is my Xylem Water Pump noisy?
A noisy Xylem Water Pump can stem from a few issues. It might not be thoroughly air purged. Another cause could be foreign objects inside the pump. Finally, worn bearings can also cause noise, in which case you should replace the pump.
Why is my Xylem Water Pump running for 1 minute periods?
If your temperature-controlled Xylem Water Pump runs for only 1-minute intervals, it suggests the water temperature signal is interrupted. In this case, the solution is to replace the pump.
