How to change your espresso machine’s brew head seal

Standard

Does your coffee machine leak around the brew head?

It is possibly time that you consider replacing the brew head seal on your machine. See our guide below and also a list of other things to check before replacing the seal.

Pro tip: Before you begin, turn your machine on and let it heat up. Once it has heated up turn off and unplug the machine, then follow the instructions. This will make it easier to unscrew the filter. #1 Remove the attachments (drip tray, water reservoir, filter handle … etc) #2 Turn the machine upside down #3 Unscrew the filter #4 Remove filter and the old seal #5 Wash the filter #6 Fit the new seal and put it back together

How to change your espresso machine’s brew head seal

Pro tip: Before you begin, turn your machine on and let it heat up. Once it has heated up turn off and unplug the machine, then follow the instructions. This will make it easier to unscrew the filter.

  1. Remove the attachments (drip tray, water reservoir, filter handle … etc)
  2. Turn the machine upside down
  3. Unscrew the filter
  4. Remove filter and the old seal
  5. Wash the filter
  6. Fit the new seal and put it back together

Things to check before replacing the seal

  1. Is your coffee ground to fine? this will create to much pressure in side the filter cup forcing the fluid out of the sides instead of the bottom
  2. Is your dual walled filter blocked? you can check this by fitting your dual walled filter cup to the machine, with out coffee in it. If your machine still leaks their is a blockage in between the filter cups two layers.
  3. Is your brew head collar worn down? When the filter and filter handle is securely fitted to you espresso machine, the handle should be positioned in the centre (or just past the centre, to the right). If your handle easily pulls to the extreme right it is likely that your brew head collar is worn down and needs to be replaced along with the seal. This can be a particularly involved solution; you may want to consider taking your machine to a espresso machine service agent.

Washable or disposable vacuum cleaner HEPA filter?

Washable Vacuum Cleaner HEPA filter
Standard

When there is a choice between a washable or disposable HEPA filter, get the disposable option.

While some would think I say this to increase repeat sales, the real reason is that washable vacuum filters are almost impossible  to clean to a standard of a new HEPA filter.

Customers that reuse washable HEPA filters after cleaning do not achieve the renewal of suction that is resulted by replacing the filter. This is particularly true when the HEPA filter is a premotor filter in a bagless vacuum cleaner. To top it off, in some instances the suction of the cleaner is actually worse after washing the filter. This happens for a couple of reasons:

Particles are trapped in the HEPA filter by interception, impact or diffusion of the particle into the filters fibres

HEPA filters work differently to other air filters that, simply put, act like a sieve only stoping particles too large to fit through its pores.

  • HEPA filters are designed to remove very small particles (like pollen and carbon from the motor brushes) from the air expelled by your vacuum cleaner. To do this, HEPA filters work differently to other air filters that, simply put, act like a sieve only stoping particles too large to fit through its pores. HEPA filters also trap tiny particle in its fibres (the literally get stuck to the fibres as air passes through). Washing a filter can remove surface particles but is unlikely to remove the particles stuck to the fibres.
  • When you wash a HEPA filter the loose surface particles often collect in between the weaves of filter material. As the filter dries, these particles set together and fuse to the filter. This makes it difficult for air to find a path through the filter which results in poor suction.

If you do have a choice between a washable of disposable HEPA filter for your vacuum cleaner (as is the case with most Electrolux vacuum cleaners)  buy the disposable. They are less expensive and are guaranteed to renew your suction fully.
