  If your Astralpool Water Pump isn't running, start by checking the hair and lint basket for obstructions. Also, there might be something stuck in the impeller. You can try using a flathead screwdriver under the cowl to free the impeller. If it moves, the motor might have failed, and you should book a technician. Remember, impeller jams due to debris are typically not covered under warranty. Damage to the basket could mean a piece of debris has passed through to the impeller, which can cause a jam in the pump.

Why is my Astralpool Viron XT 2 Water Pump not priming?
- M
  Michael AllenAug 15, 2025
  If your Astralpool Water Pump isn't priming, a reason could be a maintenance delay. Here’s what to check: * Inspect the skimmer basket for debris buildup, which can reduce flow. * Ensure suction cleaners are disconnected as they can be restrictive. * Check the pump's hair and lint basket for debris and damage, ensuring it's correctly seated to prevent air entering the system. * Clean and grease the lid's O-ring with HydroSlip, replacing it if damaged. * Remove, clean, and inspect the O-rings of the fittings on the pump's front and top, replacing them if needed. Wash the thread on both sides of fitting with fresh water and refit.

How to fix an Astralpool Viron XT 2 Water Pump leaking under the lid?
- A
  Andrew CherryAug 26, 2025
  If your Astralpool Water Pump is leaking under the lid, it could be due to a cracked O-ring (caused by lack of Hydroslip) or an unsecure lid. This is general maintenance. If the lid itself is cracked and under warranty, a replacement lid and O-ring may be available at no charge. Leaks under the pump may be caused by general wear and tear or poor water chemistry affecting the mechanical seal. In this case, book a technician.
