Question about Philips Senseo HD7832 Coffee Maker
I just got this machine. I flushed the machine, made one cup of coffee this morning. this afternoon I turned it on and the on/off light keeps flashing rapidly even though the water reservoir is full and the float is up at the highest level.

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

Sounds like resevoir was not seated properly or something is in the resevoir. try pushing the pin on the bottom of the resevoir, do it over the sink, and see if water comes out. if tht works then its internal to the machine. Call senseo at 866-4-736-736 866-4-Senseo and describe the problem.if you have purchased or received it as a gift less than two years ago they will send a new one FREE.

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.

SOURCE: not heating up still cold
I had the same problem after only a few months. There is a float at the side of the water resivour, this float also has a magnet attached to it and for some reason becomes lodged at the bottom of the tank, telling the machine that there is not enough water in the tank, even when there is. Use a magnet on the outside of the resviour, connect it to the one on the inside and lift very slowly upwards...Hey presto the light stops flashing and the water boils

you are correct in thinking the problem is caused by the valve. Use a magnet to connect to the valve from the outside of the machine, slide the magnet very slowly upwards along the water level, the rapid flashing should stop and the water should begin to heat, if not try again as you have not connected the valve to the magnet
