20 Most Recent Krups Burr Coffee Grinder - Page 9 Questions & Answers

If the cold water pumps from the bottom of the unit, you may have a problem with the one-way valve. Normally, this valve opens when the water is hot enough to pump up to the coffee basket, but closes to prevent the hot water from flowing back into the reservoir. If this valve is sticking, that could produce the symptoms you describe. Without actually seeing this unit, I don't know whether the valve itself can be replaced. This may require replacing the whole machine.

It seems like it must be detecting an error of some sort. Maybe the boiler is not heating, maybe the pump is not pumping, only testing will reveal the cause.

Probably providing more info that includes the model number will help someone to help you. Have you any idea how many coffeemaker models Krups have made?

We have had this problem twice now. The solution is to drill (yes drill!) through the capsule - a blocked outlet from the capsule itself and the injection of hot water creates a high pressure seal - you have to release the pressure. Do this over the sink - I had hot chocolate spraying about 6 feet from the machine when the pressure was released!! But this solved the problem.

Hi Rui, why not just order the correct parts? The high pressure silicone tubes are all the same diameter but the service data does not say what it is . The part number for the longest tube is OAO1478 and the hose clips are part number OAO1451

Unplug it.

Sorry we do not sell part here nor have any means to locate them for you.

Do you think it may need the amount ow water flow to be reprogrammed? If you think it's a possibility then when making your next coffee press and continue to hold down the 1 cup button until you have the amount of coffee you require in the cup. Then make another cup the normal way without continuing to hold the button, you should get the same quantity of coffee as the previous cup now.

E4 usually refers to a female torx socket. Size 4.

It seems that there is some electrical fault causing uncontrolled power to go to the plate and cause it to heat until the fuse blows. I'd be suspecting a fault on the PCB.

You will probably get some proper help if you identify the exact model. I don't expect "error 2" to mean exactly the same on every model Krups have ever made, narrow it down a bit for us please.
