Thanks @DavecUK and @Cuprajake
pinky-and-me your solution seems to have worked but every time I refill the tank Ive got to adjust the tube because it ends up touching the other wires or resting against the wall. Some days it can be really fiddly.
I might need to get a little plastic/wood raiser and use it on the top of the lid to keep it centred.
Over all machine has been great, have a few comments on what could be improved. Some could probably be done on all current machines.
