How do I maintain the condensate drainage on my Ariston heat pump water heater?

Regularly verify that the condensate water runs out to a suitable drain without hindrance. Check that the condensate drainage pipe is not obstructed.

How do I repressurise my Ariston boiler?

Switch off the boiler and let it cool for 4-6 hours. Locate the filling loop (usually a silver braided hose beneath the boiler), ensure valves are closed, then slowly open the valves to allow water into the system while watching the pressure gauge. Close the valves when pressure reaches 1-1.5 bar. If your boiler repeatedly loses pressure, this indicates a leak or faulty component. Do not continuously repressurise without investigating the cause. Contact a Gas Safe registered engineer to diagnose and fix the underlying issue.

How do I maintain my Ariston electric water heater?

First ensure the boiler's Wi-Fi module is enabled in the Connectivity Settings menu. Restart both the boiler and your router. Check your network uses 2.4 GHz frequency as 5 GHz networks are not compatible. Verify the Ariston NET app has permission to access Wi-Fi in your phone settings. If issues persist, check for firmware updates in the app.
