Leak on Profitec Pro 700

My Profitec Pro 700 is leaking from what I think is the discharge nozzle (see picture). It's not a huge leak, more like steam and small drips of water however it happens regardless if the shot is pulled or not. The result is that the water reservoir ends up empty after the machine stays on for longer time periods. I don't see a difference in pressure when pulling shots or steaming milk.

I did consult this page from Whole Late Love but I am not sure which solution to try as I'm not sure which part of the machine might be faulty: https://support.wholelattelove.com/hc/e ... ec-Pro-700

Any advice?

Thanks,

It sounds like #4 in the WLL article: try a backflush, and if that doesn't work, do a full service on the group head. Is it still under warranty? If so, WLL should be able to give you replacement parts and walk you through the repair process.

In addition to back flushing and replacing the o-ring, you'll want to root cause this to prevent it from happening again. First suspect is your water. What kind are you using? It likely has some scale-building minerals.

Thanks, I will try the backflush first and see from there. Yes, the Profitec is still under warranty. I use re-mineralized water, i.e. I supplement distilled water with ions.

What is your water recipe?

Actually, after closer inspection, it seems like the vapor is leaking from the little valve (expansion valve?) - see https://pasteboard.co/ugmkxLT9AZH8.jpg

Not sure where the problem might be; will likely have to contact WLL.

For the water, I use this recipe: https://www.wholelattelove.com/blogs/ho ... brew-water

After some searching, I found this: https://support.wholelattelove.com/hc/e ... ak+problem

I will open up the machine and try to clean that seal. Let's hope that fix the problem

The seals deteriote, at least mine did when it showed these symptoms. I'd order the o ring now so you don't have so much down time. While I waited I turned the steam boiler off and just made Americanos until I was able to repair the valve.

Well, I doubt the steam is coming from the E61 discharge chamber (the preinfusion chamber that makes up the lower part of the E61) that you've circled in the photo. Based on your symptom description it is coming from that steam boiler overflow spigot behind the part you've circled in the photo and is due to a leaky vacuum breaker valve on the top of the steam boiler.

You are 100% correct - I did found that as well and circled it in another photo (see my post #6). Will order the O-ring and change.
