E10 on Viessmann Vitodens 050-W B0HA-25

The boiler has lost its connection to your home internet, which only affects remote monitoring and app control, so your heating and hot water should still work normally.

Monitor it

This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.

What the manual says

If "E10" is displayed, the connection to the home network could not be established. Check the router and the network password.

DIY fix possible

Check that your home router or Wi-Fi is switched on and working, and that other devices can get online.Confirm the Wi-Fi password entered in the boiler's settings or the Viessmann app is correct and matches your router.Switch your router off at the wall for 30 seconds, then back on, and wait a few minutes for the boiler to reconnect automatically.If the error persists, move the router closer to the boiler or check the boiler's Wi-Fi module is seated securely, then contact a Viessmann-approved engineer if it still will not connect.
