What to do if Xylem Switch shows Alarm A02 overcurrent?
- B
  Brooke GomezAug 5, 2025
  If your Xylem Switch displays an Alarm A02, indicating overcurrent, take the following steps: 1. Verify that the set nominal current matches the value on the motor rating plate. 2. Inspect the motor windings for any damage. 3. Check the power absorption. 4. Ensure the power cord's cross-section is adequate. 5. If the power cord is longer than 30 m (98 ft), increase the set nominal current by 10%.

Why does my Xylem Switch show Alarm A11 minimum pressure?
- C
  Christina WiseAug 11, 2025
  Alarm A11 on your Xylem Switch indicates that the pressure is below the minimum threshold. This could be due to several reasons: * Check the setting of parameter 10. * Ensure there is a sufficient water level and pressure. * Make sure that you repeat the priming procedure, if there are air bubbles in the suction pipe or in the pump unit. Refer to the manual of the pump unit. * Eliminate any leaks in the discharge pipe. * Decrease the flow rate if it exceeds the maximum permitted. * If the pump unit is faulty, send it to an authorized workshop for testing. * If the motor (coil) is faulty, repair or replace it.
