Use the correct descaling agent
Only citric acid-based descalers are suitable for descaling the SENSEO
type of descaler descales the machine without damaging it. For the correct amount,
see under 'Descaling procedure' below. Each descaling mixture can be used only once.
After use, the descaling mixture is no longer active.
We advise you to use the special SENSEO
Read the instructions on the package of the descaling agent.
Never use a descaling agent based on mineral acids such as sulphuric acid,
hydrochloric acid, sulphamic acid and acetic acid (e.g. vinegar). These descaling
agents may damage your SENSEO
1 Mix 50 grams of citric acid with 1 litre of water in a measuring jug. Stir until
the powder is completely dissolved.
2 Fill the water reservoir up to the MAX indication with the descaler mixture.
Then put the water reservoir back into the coffee machine. (Fig. 3)
Note: Not all SENSEO
machine types have a water reservoir with a capacity of
1 litre. If you have a SENSEO
machine with a smaller water reservoir, repeat steps
2 to 6 with the remainder of the mixture without filling the water reservoir up to
the MAX indication.
3 Press on/off button 3. (Fig. 10)
The machine is ready for use when the indicator light lights up continuously.
4 Place the 1-cup holder h with a used coffee pod in it in the coffee machine.
Close the lid and make sure it is properly locked.
Note: Always put a used coffee pod in the pod holder when you descale the
machine. This pod serves as a 'filter' to prevent the sieve or hole in the pod holder
from getting clogged with scale residue.
5 Put a bowl with a capacity of at least 1500ml under the spout to collect the
descaling mixture (Fig. 8).
6 Press the 2-cup button hhand let the machine operate. Repeat this until
the water reservoir is empty. (Fig. 25)
Never interrupt the descaling process!
7 Repeat steps 1 to 6. Replace the used pod with another used pod to filter out
the scale residue.
Note: To descale properly, you have to use 2 litres of descaling mixture.
Never descale the SENSEO
coffee machine with the lid open. Make sure the lid is
8 Rinse the water reservoir with tap water. Fill the water reservoir up to the
MAX indication with tap water and repeat steps 3 to 6.
Note: Do not refill the water reservoir with used hot water or the used descaling
9 Fill the water reservoir with fresh tap water up to the MAX indication again
and repeat steps 3 to 6 once more.
Note: Always rinse the machine by letting it empty two full water reservoirs.
10 Remove the used pad and clean the pod holder after descaling to prevent the
sieve or hole in the centre from getting clogged.
It may be the pod holder,there is a seal under the black disc at the bottom of the holder,the water will bypass the coffee under pressure,travel to the outside of the pod holder and exit the centre where the filter mesh is,if there is no foam also this is a sure sign,fill the empty pod holder with water and see how quick the water drips,I had this same issue and bought a new pod holder and compared,should be no more than 1 drop a second,you can knock the plastic out and re seat the O ring or buy a new holder,hope this is of use to you
You may find that the plastic disc on the bottom of the pod holder is not sealing (there is an O ring) ,if the amount of coffee dispensed is more than usual that will be the problem,just buy a new pod holder.
I don't know if you've tried this, but it works like gangbusters for me. I use non-senseo pods with the 2-pod holder, and they're too big for the 1-pod holder but not quite big enough for the 2-pod one.
I would frequently end up with a lousy, weak cup of coffee, and after a little investigation I deduced that water was flowing into the pod holder and AROUND the pod, without going THROUGH the pod directly. The name-brand senseo pods fit perfectly, and always produce a strong cup, even if I don't like their coffee, and it's because there's such a tight seal between where water flows in and where it flows out.
Simple solution: Put your pod in with the flat part facing up, and the bulgy part facing down. Press it down hard into the 2-cup holder. Run a little HOT tap water, and lightly wet the surface of the pod--not so much water that the pod starts floating in the holder, but enough to get it soggy. Then make your cup of coffee. The water will flow through the pod first, and kind of like siphoning gas through a hose, once it's started going through the pod it won't stop. Instant awesome cup.
The pod holder has an O ring to seal the black plastic disc in,if it is not sealed you will end up with more volume and a weaker coffee without the foam,either knock the disc out and try and seat the O ring and then knock it back in or buy a new pod holder,I had this same problem
Having dismantled and inspected several of this "strange machines" my conclusion is the following:
There is an oscillating-piston pump inside with in- and outlet valve.
It is energized by a microprocessor controlled circuit for a working time depending on the button selected (1 or 2 cups). The pressure and flow are nearly constant for a perfect working pump.
The pod holder restricts the thruput by its central hole. (E.g. you get now an extra pod-holder with a very small hole for expresso type)
So if you don't get enough coffee it may be that
1) the duty-cycle (timing) of the pump has changed.(not often occurring) no repair, you have to undergo electronic and programming work
2) the pump lost efficiency (cylinder of the pump clogged, piston not working with complete stroke, spring force fadening or just one of the 2 valves leaking) ca be "repaired" after dismantling machine ,extracting pump and taking it apart, success not garanteed - grinding valves is already time spending
so my principle before starting this work is to run the machine without the coffee pod to check the water output, use a new holder with clean central hole, if this works it will be nr.
3) the central hole of the holder is clogged, may be not by limestone, but dried coffee extract (grease) clean with needle or even better with micro-drill
