Water leaks through showerhead during pre-heat

f you see water leaking out the showerhead, it is probably caused by coffee particles holding open the pressure valve.

The pressure valve prevents water from flowing through the showerhead under normal atmospheric pressure. This enables filling of the waterbowl with water even if it isn’t on top of the handle. However, if any of the edges of the valve inside the showerhead have been blocked open it may leak a little before the trigger has been pulled.

To fix this you need to open the showehead and give it a rinse.

Please follow these steps:

Remove the showerhead from the water bowl. Turn it over so the metal side is facing into the palm of your hand. Then use an object such as a chopstick or other narrow blunt instrument (a teaspoon handle often works well) to gently push through each of the four holes on the other side of the showerhead. You are pushing the rubber valve against the metal showerscreen which, after a small amount of effort will shift the large o-ring that holds it in place and is also used as the main seal against the coffee basket. The metal showerhead and o-ring will pop out into the palm of your hand.

This exposes the rubber valve.

Give the entire assembly a rinse, lifting the edges of the rubber valve to remove any particles that may be holding it open. Then reassemble in reverse order placing the metal showerscreen against the valve and push the o-ring into place around it.

If the o-ring has a flat side to it, ensure the flat side stays facing out as you push it into position. It doesn’t have to be perfectly flat, but it does work better if it’s all facing out and not twisted around.

When you are finished, insert the entire assembly back into the water bowl.

You should not see any more drips from the water bowl when you fill it with water.
