Question about Krups Novo 2300 Espresso Machine

2 Answers

I have not used my krups novo 2300 plus for several years. When I attempted to restart, I had problems. I filled the container with water, turned on the on/off switch, waited for the lower light to go out, then moved the lever to the right. In the past, a few seconds later, coffee would be dispersed through the machine. Instead, when I move the lever to the right side, the pump sound occurs, but no water is pumped through the machine. I have noticed the "burner" is hot. I have removed the screws for the "burner" in an attempt to clean the parts in case there was a lime buildup or something like that. everything appears to be clean. Help!!!

Empty as much of the water as possible and fill about half way with white vinegar. Let sit overnight. The vinegar will clear most buildups that may be causing an obstruction. After sitting overnight turn unit on and allow vinegar to run through. This should clear the machine. Once cleaned run clean water through machine 2 or 4 times to clean out the vinegar.
If this does not clean it buy a small bottle of CLR and use that in place of vinegar. CLR is a cleaner for Calcium Lime and Rust

    Go ahead and use the CLR. Just do a couple of extra rinseing afterward.

Krups Novo 2000 ~ water isn't flowing. I bought this used at a yard sale, and I must say it looks as tho it was hardly used at all. Today I plugged it in, turned the power switch to on until the temp...

If the pump is bone dry sometimes they refuse to pump. In the past I have found some soft tubing that will fit over the water inlet where the tank plugs in. I then fill the tube with water and pressurise it with my mouth while operating the pump. Often this is enough to prime the pump and start it pumping. The downside with a machine that old will probably be lack of new group head seals, you will probably find they are obsolete.

There isn't enough pressure to pump water through the coffee

Chalk in the system, let it run a couple of times with plain vinegar. just fill the machine with about half a liter (one water container) vinegar and collect the vinegar in a cup so you can reuse it. run the full 0.5 liter, wait an hour and repeat. Than run 2 full watercontainers plain water. should work again. Cheaper than antichalk fluid and works the same
