thanks all for the advice and help. my machine got back today from essential coffee services in Bankstown. 2mcm was exactly right with his diagnosis, (if i got a response earlier i would have taken it to you!). the total cost of the repair was $500. which included the replacement of the wiring loom and board, general service and clean, replacement of shower screen and group head seal, replacement of all other seals around front of machine. everything sits much tighter now, especially around the lever where it was leaking a bit of water during an extraction every now and then. although that's expensive i dont think they ripped me off considering what they did. what was a little annoying to me was that it was at their shop for a week before someone got back to me and diagnosed the problem. that's pretty average in my opinion. what was first rate was the bearded bloke on the front counter, (forgot his name now), great guy, excellent customer service ! poured my first cup of campos today and it was devine ! all set for a weekend roast aswell so life is good. 🙂
