Has any Alex Leva owner encountered a leaking valve that is used to steam the cup warmer? Right now I have a very slow constant leak through the cup steamer valve. I've tried to use steam to clear anything from the valve but the valve leak does not change. It looks like this is a ball valve. I am wondering if it is misaligned so that the valve does not fully close. I am looking for suggestions to solve the leak - Thanks

Do you have an exploded diagram of the machine that might put you on the right path?

I found a set of diagrams on Chris' Coffee. Looks like I'll need to remove panels and start exploring.

You are not alone,
I have had this problem for some time. Because of the valve leak you mention,
water is pooling under the cup tray. The machine is on a timer and switches off at 18:00 hours. In the morning
the water is gone. I assume some of it drains and some evaporates. Most of the days there is a small
quantity of water (shape and size of a quarter dollar) that dripped overnight from the steam switch at
the bottom right side of the machine. Unfortunately I have not made the time to address the issue.

Must be a seal in the valve?? Is there a fitting you can tighten/adjust to apply more pressure to the seal like on a normal steam valve?

I've looked at the stem and can't readily see how to tighten to valve seal(s). From looking at schematics for ball valves in general, it looks like the inlet and outlet ports each have a seal.

I've decided to put a 1/8" BSPT plug in the port on the boiler for the steam supply to the cup warmer valve. I rarely use the tray steamer since the valve is inconveniently located behind the drip tray which must be removed to access the valve handle.

Here is a clip from the exploded view (the valve is FE1409):



In and out ports are 1/8 F BSPT

I can upload a photo of the actual valve after I get it removed from the machine.

Here are a couple of photos of the valve:





It looks like the valve stem assembly has been pressed in and is not serviceable.

You'd have to remove it & look in from the other end. If it's like the shut off/drain valves used on boilers there's a ball inside sitting in a teflon cup. These are held in place by a threaded fitting that can be removed or tightened using an allen wrench.
