Potterton Suprima 30 E119 error code

Hello Guys,

I have bought & installed my Potterton Suprima 30 one year ago. The boiler is displaying an E119 error code for last three days. Due to this, the boiler is not working. I have restarted it several times but all in vain. Someone, please help me



Hi Tony,

In Potterton Suprima 30 boilers, an error code E119 deals with the low-pressure faults. You have to face this problem whenever the boiler’s pressure goes below bar 0.5. Well, do not worry, as the simplest solution is right here. Just open a filling loop & try to increase the boiler’s pressure. You might have an exterior filling loop or even an in-built. The best way is to; read the user guide manual on how you can use the filling loop for increasing the pressure safely.
