Profitec Pro 400: Steam/Hot Water Valve and Seat Gasket Service

Use this article to disassemble the steam/hot water valve and access the valve gasket in your Pro 400. This is useful if the valve fails to actuate or develops a constant drip.

Tools Needed:
- Adjustable wrenches (x2)
- Pick or other similar implement
- Towel
- Molykote food safe lubricant
- Replacement spindle seat valve gasket

1. Start by opening the valve all the way by turning the knob counter-clockwise.

2. Identify the tool flats on both the steam/hot water arm and the valve assembly. This is where you'll need to place the wrenches to get a good grip.

3. Hold the arm steady with one wrench while you loosen the base fitting of the valve assembly with the other wrench.

NOTE: Be careful not to damage the chrome finish. You may want to drape a towel over the valve assembly or tape off the jaws of the wrenches with masking tape to prevent them from marring the chrome finish.

4. Once you've unscrewed the valve assembly from the arm, inspect the rubber gasket that seals the valve. In many cases this gasket just needs to be cleaned off and the valve reassembled to resolve the issue.

5. If the gasket is damaged or badly worn, pry it out with a pick or similar implement, like a narrow screwdriver.

6. Then, apply a bit of Molykote to the narrow end of the gasket and press it into place. *Note: The new style gasket will be white and made of Teflon; pictured below.
