Main Combi 30 Boiler E1 Error

[subzero]

Our boiler was switched off over the wkd, when we returned there was water on the floor underneath (there is a regular drip from underneath the pump) and when switched back on the display alternates between the temperature (19) and the error code E1. We've tried resetting but it makes no difference. The pressure is showing zero. What on earth could have caused this?

Pics attached of pump and screw underneath where the drip forms, tried tightening the screw a little but made no difference.

Thanks for any help - it's freezing here!

The error code is E119, low system pressure. Top it up to just over one bar. Obviously you will have to find/fix the leak first.

Brilliant, thank you. Problem sorted. Re-pressurized and now working. We'll have to get someone in to sort the leak.
