I bought my senseo philips HD7825. I loaded the water then plugged it in then I added the coffee pod. However, the power light kept blinking (slowly) as though it is heating up. But it is not heating.

contact the mfg.

my senseo did the same. i read on hear to clean magnet/float mechanism inside the water resevoir. i did this with a tooth-brush and soapy water. as you invert the empty water container you will see/hear the float slide up and down when clean. work a treat for me.

Either the little magnet in the reservoir is stuck (does it float when you slowly fill up the reservoir?), or the corresponding Reed relais doesn't properly respond to the magnets presence. The latter most likely requires technical attention.

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 probably are not putting enough coffee in to strengthen the coffee

Eureka! I have solved this problem.
Disconnect your Senseo from the power. Take it to the sink. Hold it upside down and put hot water in the coffee outled. In less than 30 seconds the senseo will open.

The problem with Senseo is that - especially with coffee holders for 2 cups and chocolate - after making the coffee, the pod holder and the pod cool down. This creates an underpressure, that prevents you opening the Senseo. Hot water will increase the pressure and then you can open the senseo very soon.

This solution was found in despair after struggling with all the complex tool involving (knives, pumps, etc.)

Let me know if it works for you

senseo now makes pods in many coffee flavors and coffee varities
can be bought via internet

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.

I had the same problem. I waited for a while as the instruction says but didn't open. But, I got it open!!! by turning and slightly pulling a small plug behind the water tank on the backside. (remove the water tank then you'll see the little plug. see attached photos) I think it will let air in and vacuum seal get released. After it opened, I gently turned the plug back and push it in as it was. Now, it is running perfectly again. I just had a great coffee. :-)

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
