My machine is now about 9 years old and has only been used infrequently. Recently the pump seems to be faulty as will initially start to pump water through the coffee with usual noise but then stop and hum after about 15 secs with no further water being passed. Is it a pump problem or a build up of pressure due to blockage of the sieve?
I had a similar problem with my machine but discovered it was due to a build up of scale in the internal pipes which couldn't be shifted by normal de-scaling - solution was to dismantle and clean plastic pipes manually.

The wand can leak if the rocker switch is not in the UP position.
In MIDDLE position it will try to deliver hot water.
In DOWN position it will try to deliver steam.
The thermoblock in this unit is actually a 3-way valve, of which two positions route water from the boiler directly to the wand. The 3rd position (UP) routes hot water (but not steam) from the boiler to the group head.
Try holding the switch in the UP position by hand when making coffee. If the machine still pushes water through the wand then you will have to replace the switch inside the machine that is activated by the rocker, or the valve it operates.
The POWER LIGHT for the 889 is RED and located on the LEFT of the center cowling
The BOILER LIGHT for the 889 is YELLOW and located on the RIGHT of the center cowling
If you turn on the power to the unit (the INNER SWITCH on the RIGHT
SIDE) the RED light should turn on, showing that the machine is powered. At that point the YELLOW light should also turn on for about 10 seconds, at which point it will turn OFF with an audible CLICK.
If the RED light does not turn on then you have a very dead machine.
If the RED light does turn on but the YELLOW light does not then you have a half dead machine.
Opening up and repairing the 889 is not for amateurs. High voltage, heat and pressure inside.
If you decide to bin the machine I would appreciate getting the drip tray from you as I have lost mine.
Most likely you have developed a leak where the pump joins with the boiler. If you put descale chemicals in the reservoir then they may have been baked into the boiler and the backpressure has either ruptured or unseated the tube that leads into the boiler.
I have the same problem and clean the filter using a small brass bristled brush (I think it is a suede brush).It is the only thing that seems to get in the holes.I can't get it completely clear but it does seem to do the job.I also thought of getting a gas mantle cleaning prong but haven't tried it yet.It seems to be a build up of coffee that causes the problem.Spares seem to be a problem because the machine is obsolete.I'm thinking of buying another machine off e-bay to use as spares.
1) Turn machine on (innermost right switch) 2) Red light goes on (power on) 3) Yellow light goes on (thermablock heater) 4) Wait for yellow light to go off 5) Detach handle (pull to left) 6) Clean handle, remove crema sieve, clean with soap & water 7) Put crema sieve in handle (you should have a choice of two) 8) Put espresso ground coffee in with brown handle 9) Tamp coffee down FIRMLY with handle 10) Place handle back into machine (push to right) 11) Ensure flip switch on leftmost side is at top position 12) Flip down rightmost switch to infuse coffee into handle 13) Wait 18 - 24 seconds 14) Flip up rightmost switch to turn off infusion 15) Put milk into container (about 200ml in a 600ml container) 16) Flip down rightmost switch to bottom position = steam 17) Keeping tip about 5mm from top of milk, foam to ~400ml 18) Place sugar in coffee, if desired 19) Pour milk in coffee
descaling time not with vinegar with descaler vinegar remove calcium in little piece descaler melt it use 1 part descaler 1 part water put in the water container start it up open valve after a few second turn it off leave it for15 minute repeat untill empty after do 2or3 rince descaler is corosif thank you for using fixya pierre
