I have a Breville 980XL (second one I've owned, so know their quirks). I've replaced the o-rings without problem, and have replaced the primary 3-way solenoid attached to the grouphead in the past when it starts buzzing. I started to have water leaking down the vertical backsplash recently, which I've never seen before.

Happens with pulling a shot or using the hot water function. Figuring that this was a leaky o-ring, pulled the top, replaced them, and still had the issue. Looking at the solenoid on the right (see photos), this isn't the normal 3-way one that many of us have had to replace in the past due to buzzing.


Happy to replace this one, but having a little difficulty identifying the right part to order. Any thoughts, or any way to just fix this one? What's happening is that water is leaking up out of the top of it when it's activated, and that water is then running onto the floor of the front panel inside and leaking out the seam where it attaches to the backsplash.
