WIDL146 How can I fix "f04 light 2. pressure sw stuck on empty "?

As expected I called professional assistance, they could not identify the problem... even though they saw the flashing light (WIDL146, F04, light 2). Question: Lets say that the tube is clear, but before sending main module to www.emwelec.co.uk, as suggested by Graham, would replacing the pressure switch work?

Thank you Graham! I did what you said... the tube is clear. As I am living in Italy, I decided to call assistance... let's see what they say.

SW means pressure switch. It could be a blocked pressure switch. Unplug the machine, remove the lid and you will see the press switch - a round plastic device with a small tube going into it. Pull the tube off and blow into it (the tube). If it's clear then it will be easy to blow. If not, then find and clear the blockage. If this is ok, then send you main module to www.emwelec.co.uk who will test and repair it for you.
