Vaillant ecomax F.25 fault

[bobbaray]

Evening

All this is my first post and i'm looking for some help.

My ecomax boiler is showing an F.25 fault on the display.

Does anybody know what this means as the manual shows F24 then jumps up to F27

Thanking you in advance

F.25 Water Switch Water Switch - plug disconnected
System pressure too low Waterswitch activated

Thanks very much

I pressure now increased and all back to normal, I bleed all the rads earlier in the day which must have decreased the water pressure.

Thanks again

Bobby
