Philips EP models: Replace the seal in the brew group

Introduzione

The seals in the brew group are subject to heavy wear. In particular, the large O-ring on the piston needs to be replaced from time to time. This is how to do it.

These instructions can also be used for other Saeco models and for Philips and Gaggia coffee machines – all of them are from the same manufacturer and are very similar in design.

    • The spout for the hot coffee is located on the top of the brewing unit. It is fastened with two screws. Underneath is the crema valve. It consists of a spring and a little glass ball. Make sure the spring is reinserted with the thin end touching the glass ball when re-assembling.

    • Remove the two Torx T10 screws on the crema valve.

    • Lift off the crema valve minding the spring and the glass ball.

    • The upper piston is held in place in the frame with four locking pawls. Push down all four latches with a spudger, then remove the piston by pushing it downward.

    • If you want to replace the gasket, you can do this now and re-assemble the device and stop here. However, a general maintenance of the brewing unit is strongly recommended.

    • Unscrew the Torx T10 screw on the brewing sieve and remove it.

    • You can push out the lower piston from the brewing unit if you snap the deflection lever out of its socket with a screw driver.

    • Clean all parts with very hot water and dishwasher liquid.

    • Grease all moving parts with food grade silicone fat. Dont forget the tracks in the side panels.

    • Take this opportunity to carefully replace the two O-rings on the support valve. The larger one is at the top. These two seals are stressed during every brewing process. Therefore, lubricate them with food-safe silicone grease.

    • On some models, the support valve is covered. In this case, you must unscrew the cover first.

Hallo Martin,

Zou u mij ook kunnen vertellen hoe ik een EP3510 kan open maken?

De mijne heeft geen schroeven aan de achterzijde en ik wil de pomp nakijken.

Ik kan wel heet water pakken maar koffie geeft hij niet dan valt hij in spelcyclus wat duidt op een verstopping en hier door kan ik hem ook niet reinigen.

Hoop dat u een antwoord heeft.

Mvg,

George

I wonder, I thought all EPs can be opened the same way. I have a link to the service manual, perhaps it is useful for you, especially the testmode.

Dat vraag ik me af, ik dacht dat alle EP's op dezelfde manier geopend konden worden. Ik heb een link naar de service manual, misschien heb je er iets aan, vooral de testmode.
