    The product is not under warranty. Where do I get the valve and do I need to dismantle the machine to get access at the valve?

  • pamneuman Sep 01, 2010

    Is there a specific name for this valve, so if I need to replace it I can locate it? Pma

    Do you mean putting full strength Real Lemon juice (bottle) into the water tank and run the espresso machine like it was making a latte?

Based on the information provided above the machine is a bit old as 3 years of regular use is quite a while. If the frothing wand is the only part of the machine which leaks water it can be presumed that a replacement of the part is in order.
It will be advicable if you can afford a new machine to get a new one otherwise get an expert to replace the frothing wand and run a general service of the entire machine.
Water leakages around electrical appliances are very dangerous and the consequences are always disastrous. So ensure that either the device is handled by an expert or replace the unit completely.
Hope this solution has been helpful?

Hi,
We understand that your problem - d2336e4.jpg

This valve will differ based on the DeLonghi models
If the machine is still under warranty you may void the warranty any time you take it apart.

When water heats it expands which creates more pressure in the boiler. This pressure may allow some water to sneak by.This valve is located behind the shower screen and keeps the water from being forced out of the boiler as it heats and the water expands. When you want to make coffee and turn the pump on the valve will stay closed until enough pressure is built up to push it open allowing the water to flow. When you turn the pump off, the pressure reduces and the spring on the valve pushes it closed. When the steam button is pushed the boiler heats up to a higher temperature and the pressure in the boiler increases putting more strain on the valve.So this valve may be loose or some time may be defective one.

post a comment for further assistance.
Thank you for using fixya have a nice day:-)

    Boiler pressure valve.If you have proper tools you can take it else you will mess and don't break the boiler.It cost very less to change it in service centre.

    Thank you.
