Question about Krups XP2070 10 cup Coffee Maker/15 bar Pump Espresso

1 Answer

The espresso side of the machine stops pumping water after 5 seconds or so. At the same time the espresso on/off button and main display start blinking. Pushing the hott water/steam button will reset this condition. That is: wehn you push the espresso button, the espresso will run for another 5 seconds or so. It takes 4 of these iterations to fill one cup of espresso. The hot water tap has the same problem: pump shuts down after about 5 seconds. Would appreciate your help.

    I have had the same problem. I have tried loose packed coffee, tight packed coffee. Removed the head and cleaned the grid but so far nothing to resolve the issue.

    I also have the same problem. I have tried de-scaling, cleaning the head, etc. Have taken the machine in for service. Fortunately, the service center is close to where I live. Don't know when I'll get it back.

    I have exactly same problem. It stops water after 5 sec or so and is blinking urgently.

The clue here is that the problem involves the hot wate and the single or double espressos. These three functions require accurate water measurements and they are programmable. It appears that the flow meter is not sending the correct information to the control unit. This could happen if you have blockages or if the flow meter is not working anymore. Most likely you need a new flow meter which only costs about $20 and should not be too difficult to replace. It is located between the water tank and the pump.

    I finally opened the machine we got for our wedding with the same problem. I tried to use the espresso side for the first time. Pump runs for a while but NO water comes out at all, totally dry. The unit is clearly heating up though. I replaced the flow meter, still no success. I sent it back to the company complaining the new machine does not work. They sent it back to me suggesting I send it to the nearest repair shop (in another state) Total drag, sick of the high starbucks bills . . . thoughts?

  • Sergio M Perez Apr 04, 2011

    In cases where the flow meter is not working properly you will get 5-10 seconds of hot water flow and then stop. If you are not getting any water out it coud be from a blocked coffee holder or a failed pump. Try running the cycle without the coffee holder just to check for the water flow. If you can get hot water for steaming or just to get hot water then your pump is fine. The only item left is the set of valves but that will mean that the hot water drops into the tray. I did replace the valves to fix mine but now the flow meter is not working after 6-9 months of usage. I am not sure I will replace the meter again.

    I have a brand new floe meter to plug in my machine but I do not not which cluster I would insert it: J3 or J6? Thks

  • Sergio M Perez Apr 20, 2011

    It should plug into the J6 connector. Good luck! The white wire should be towards the nearest edge of the board.

  • Ale Apr 21, 2011

    THks a lot, Mr. Perez it is working now with about 50 ml for 1 cup and 100 ml for 2 cups! Flow meter on power board ,J6 connector .

    I replaced the two valves and put the machine back together and since then I have the same problem. A few seconds of water from the espresso or from the hot water and then it stops and blinks. Did I not connect some of the parts correctly? Sounds strange that the flow meter stops working right this moment. Can I measure the needed amps or something, what's the specs on that?

  • Sergio M Perez Dec 27, 2011

    Victor,

    It is rather difficult to electronically check the flow meter. It is most likely a Hall Effect sensor that sends pulses back to the control board. The number of pulses translates to a given amount of water flow. If your unit pumps water for 5 plus seconds and then stops and starts blinking you most likely have a failed flow meter. Check your connections first but mos likely you have a bad flow meter. My failed again and I havenot replaced yet. Hope this helps!

Delonghi Lattissima EN 660CW milk frother not frothing


I don't know why my answer posted in the comments section, so here it is in the proper area.

I had the same problem and was ready to send it in for repairs, but I talked to a great guy at Nespresso who helped me fix it myself. The problem was when I pushed the latte button, it would only froth milk for a second or two and then the espresso would start pouring. It basically refused to make a latte. Here's the things he had me do:

1) Descale immediately. I have an older machine, and descaling once a year does NOT cut it. He told me descaling every 5 months at the bare minimum, if your machine is not having any problems at all. Descaling is usually the main problem for lack of froth. I descaled and it seemed like the machine was working better almost immediately. I also ran 4 - 5 tanks of water through the hot water spout and the main espresso part (but mostly this is because it seems to take this much flushing to get the smell of the descaling solution out).

2) Reset your machine to factory settings. I have a classic Lattissima, so this is how you do it on that machine. Turn the machine on and wait until the drink buttons are steady (espresso and hot water buttons are no longer blinking to warm up). Then press and HOLD the power button until the espresso and hot water buttons BLINK THREE TIMES. Then they'll go back to steady again. You're now back to factory settings.

I did notice that I started having the trouble after moving the machine, so I'm not sure which of the above solved the problem. The main thing is it worked and I'm back to yummy lattes!

Just bought the machine. Basically, the problem is that the steam wand goes of on its own (or as soon as I push the coffee button) and that I cannot turn the steam handle at all or do anything to stop...


Hi. Make sure all your buttons are off. (switches all facing the same direction). Then make sure the tap is turned off. Switch main power on. Then switch the coffee on. you should hear the pump start. usually loud at 1st, then it will get quiter as the water is pumped up through the group head. When water is pouring through the group head, switch off the coffee button. Now let it finish heating. If you can get to this stage, then everything is ok. If you cant get it to this stage then you have a problem with the machine. Most likely a themostat on the boiler. Darryn REPAIRER

I have a krups xp2070 that i just put a new motor in. When making espresso, the water pump does not turn off. Is it related to the little relay switch that connects to one side of the pump?


The unit is programmed to operate the pump for a very specific period of time depending on the function. Power to the pump is provided by the main power module but controlled by the control module. Either the module is not sending the right signal or the relay on the power module is stuck on. You could try programming the espresso time to reset the pumping time. Will the pump stop if you press the espresso 1/2 cup button again?

My issue: watertank is full, when powered, coffee buttons and the left LED are blinking. When I open the steam valve, the pump works for like 5-10 seconds then stops, neither water nor steam come out. Same...


HI
You have a restriction in your flow meter or inlet opening. Usually it's the flow meter. The flow meter is connected to the intake opening on the back of the machine by a silicone hose. The other hose connected to the flow meter goes to the suction side of the pump. The intake side of the flow meter has a small opening and the other side connected to the pump has a large opening. When the pump turns on and everything is clear, the small side of the flow meter creates a jet of water that spins the turbine. This lets the computer know that water is present and turns the heater on. If the turbine doesn't spin the computer thinks the pump is bad and turns the light on for water and keeps the heater from turning on and burning up. You need to clear the small opening in the flow meter.

Decalcifying method


There is an auto button on your machine the double ellipse button, hold down for 5 seconds display will read descale.

Safe Descaling method

1- Always use the right descaling products.

Descaling chemicals purchased from supermarkets may not be suitable for the machine. Use of Vinegar is prohibited by manufacturers. Please read the operating manual. Do not use Cafiza, Cleancaf or PuroCaff. These are coffee cleaners recommended for back flushing coffee machines.

2- Always dissolve the Descaling chemical in a container and pour into the water tank. Never add directly into the water tank. Crystals of chemical will slide into the filter & pump and block the water hose and restrict flow of water.

3- Do not pour solution when the tank it is on the machine. In fully automatic machines, the bean hopper is next to the water tank. The solution / water can accidentally get into the bean hopper and cause serious damage to the grinder.

4- Espresso machines have separate water passage for Hot water from steam pipe and espresso dispensing. Flush the solution from both sides, alternatively. Turn machine on, flush one cup from steam pipe and turn machine off. After a pause of 3 to 5 minutes turn machine on and make one large espresso (4-oz.). Repeat this process until all of the solution in the tank is used up.
This method is best both for semi-automatic & fully automatic espresso machines.
Using Electronic programmed method does only half the job as it flushes descaling solution only through the steam pipe. The machine must be flushed with solution from espresso side as well. Automatic descaling method should be completed by making 6 espresso with or without coffee (using pre-ground cycle when available).

5- Rinse the water tank and fill with fresh clean water. Repeat the rinsing process alternatively until four tanks of water is used up to flush the chemical out.


Caution: Do not leave the machine before completing the rinsing with clean water. The solution left inside will corrode & tarnish metallic surface.

Do not leave Chrome plated objects submerged in descaling solution for more than 10 seconds. The chrome will dissolve and leave the item permanently corroded and black.

Water tank light is flashing with main heating light


HI
I don't think your machine is finished descaling. Follow these steps.
With the machine turned on, push and hold the left 2 buttons (clean and pre-ground). This should light the top right red indicator light. Mix your descaling crystals in 32 to 48 oz in your water tank. Stir until they are completely dissolved in the water. Next have a container that can handle about 2 quarts of water under the steam wand, or have the machine positioned next to a sink. Next open the steam knob on the right side of the machine. You should hear the pump turn on and pump about 2 to 3 oz’s. of water through the wand into the container. The pump should turn off and there will be a wait of about 2 minutes. The pump should turn on again and more water will come out. It will do this until it has completely drained the water tank. Do not interrupt this cycle until the machine has stopped on its own. When it does stop, all lights on the bottom will flash. Rinse out the water tank and refill with fresh water. Place the water tank on the machine again, and then close, and then open the steam knob again and let the water just flow through the boilers until it is emptied by the machine. Don’t turn off anything until the machine stops on its own. This will clear the descale light. Refill the water tank again with fresh water and your ready to go.

Machine says ventilate


When it says to ventilate, it is asking you to prime the pump. Put a cup under the panarello wand ( the steamer/frother) to catch the discharged water and press the hot water button (upper left button on my machine). Wait until air stops coming out with the water, usually 3-5 ounces, and then press the hot water button again.

You machine is now ventilated (primed) and should be ready to go.

Espresso extraction time


You will need to reprogram the computer. To do this, it is relatively simple. take your grounds and tamp into your portafilter (I usually start with a double). make sure that you tamp it correctly.

Then, hold down the start/stop button until you see the lights flashing on the panel (if you want to program both groupheads at the same time, then hit the start/stop button on the other side as well.) Then with your portafilter inserted in the grouphead, hit the button that you would like to represent your double shot. you should see a water stream about the width of a cooked piece of spaghetti. After around 18 seconds to 22 seconds, you should have your shot levels filled. then hit the button that represents your 'double' shot to stop it. then hit the start/stop button. You will see the start stop button flash a couple times and then turn off.

That should do it. remember, that the preferred timeframe for a shot of espresso is 18-22 seconds. Your setting on the coffee grinder would then need to be set to make sure your getting a full shot in that amount of time.

Good luck
