My pump espresso machine is vibrating a lot. What can I do to rectify this?

Some vibration is normal. If the pump espresso maker is vibrating too much please check the feet on the bottom are intact as these dampen the vibration. If this is on first use, and no water is coming out of the boiler head you may have an air block, and to resolve this you should open the steam valve until water starts to flow through the steam wand for at least 30 seconds.
