Question about Nespresso Lattissima 660.R

1 Answer

I have a Nespresso Lattisima and all four lights are blinking four times in quick succession and nothing is working. I've tried emptying it out and it's done that, but still the same problem.

Was starting to make a latte and it stopped half way through and all lights started blinking. I've cleaned it out (manually, as per instructions), emptied it out. As it's brand new, can't see it needs descaling (and orange light not on). Nothing else seems to be out of order, and it's been working perfectly for one week. Took the milk compartment out to see if I could make just normal espressos and can't. It won't do a'thing now except blink (all lights at same time, four times in quick succession).

    I've tried it again, and it will start to make a coffee (ie sounds like it's working) but then it seems to think it is still emptying, as water then comes out into the drip tray. So keep going through the emptying process again as it seems to think it's in that mode. Don't know how to 'reset'.

    And now that I've done that (emptying) again, just four blinks all the time. Won't do anything. Had a power outage last night, but have surge protectors, so assuming that all is ok. Anyway, it switches itself off, so shouldn't have affected it.

Your machine has almost certainly entered the water quality mode. (Water hardness setting). This is very easy to fix. Switch machine off. Before switching back on press and hold any off the following buttons: Latte Macchaito (top right) for soft water, Cappuccino (bottom right) for medium water or finally both of them for hard water. While holding the correct buttons switch the machine back on BUT hold for approx. 10 seconds or until all lights stop flashing, (APART FROM THE BUTTON YOUR HOLDING). This will reset the machine and you're good to go. Regards Coffee Engineer!

SOURCE: Too little coffee

1080p60 is a genius! 
he is correct. the owner's manual gives you the impression that it is a three step process: 1) turn machine off. 2) push large coffee cup icon. 3) turn machine back on. BUT it does not make it clear that after turning the machine off, you must hold the coffee cup icon down WHILE turning the machine on. solved the problem perfectly. thank you 1080p60!

SOURCE: The Nespresso won't make coffee yellow light keeps blinking

This is because there is either too much water in the drip tray, the empties container is full or the drip tray is not placed correctly. This took me a while to figure out as well, and the manual was little help. Nespresso is located in Switzerland so their support number is international. Hope this helps someone...

Don't run the clean operation. Just put white vinegar/ water, half and half and run as if making coffee. Let it cool and run through about 3 times and this will remove all scaling/buildup.The rune through plain water.

I'm following the instructions on my Whirlpool range to clean the oven. I've done everything the instructions said, but it won't get going. ( set the knob to clean, set start and stop knobs...

Might be a typo in the manual typically the latch is moved to the right to close and after clean is over move to the left to open. BE SURE TO REMOVE RACKS BEFORE CLEANING

Tv turns on for a few seconds then shuts off and the blue power light blinks.

Mine never turned on but the blue power light would blink.I disconnected the upper y buffer and got light on the bottom half of screen and the blinking stopped.I have the upper board on order and I think this will fix my problem.There is a blink code somewhere,just count how many blinks.Start pulling connectors from power supply and when it quits blinking you've found the one,could also be the power supply with bad cap.

EZ3612 - spins for couple of times then stops with burning smell and mode light blinking 13 times

Per the service manual, if the mode light blinks 13 times, there's a bad dryer sensor or thermostat. I'm not sure if that related to your problem but it's a start.
