my vaillan ecotech boiler pressure is at the max on the red side?

I have a vaillant ecotech boiler. The pressure was down so I tried to raise it but forgot to switch the pressure off. It was on all night. It's now leaking and shows on the screen where you normally see the temperature 23c and 2.3 bar. Is this a serious fault and was has gone wrong?

Thanks
