Hi everyone, I came across this great forum because of my Caffeo CI 970-101 which is on strike. I think it's really great that something like this exists. I have already scurried through all possible entries that sounded similar and have tried some tips.
Our KVA is now about 5.5 years old and has about 15,000 coffees under its belt. The machine is tight and has always served delicious coffee up until now. The grinder is a little noisy now, but that's probably due to wear and tear.
We have always cleaned and descaled the machine when it asked for it. We took the brew group out at least once a week and cleaned it with hot water. Then once a month I also cleaned it from the inside to remove all the powder and dried coffee grounds slush.
Now to my problem:
Yesterday it was time again and I cleaned the inside of the machine, dried everything and then ran the cleaning program, as usual, with two dissolved cleaning tablets in the water tank. Everything ran through flawlessly and there were also no special noises or similar abnormalities.
After that I started the descaling program, for this I completely dissolved two teaspoons of citric acid in the tank with about 1 litre of hot water. Normally I use a sachet of descaler from the DM, but I didn't have it at the time. The program started normally, but after about 10 minutes I noticed that nothing was happening and I waited another 20 minutes and there was no progress at all - so I switched off the machine...
When you switch it on it starts with "Descaling - Cancel" and the Rotary is flashing, when you press it you get "Descaling - Empty bowl and container", followed by "Descaling - Put hose in spout and bowl" Rotary is flashing, after pressing Rotary you get "Descaling - fill water tank", as there is already water in it, it continues with "Descaling - rinse machine" and you hear the usual noises, it moves a little and the pump should actually start, but it doesn't - after about 30 seconds, it goes into "Descaling - fill water tank" mode. After about 30 seconds it goes into "System Start" mode and the Rotary control knob flashes. When you press it the flashing stops but starts again after about 30 seconds, the progress bar runs through to the end but nothing else happens.
As it seems, the machine is stuck in the "descaling" program and doesn't get any further.
I have already tried the following
:- Reset the machine via "On/Off + My Coffee" - all
cables in the machine checked for tight fit- all
hoses checked for tight fit and continuity- flowmeter
opened and cleaned- machine
with filled water tank (descaler) overnight let stand- 12
hours without power and without inserted CR2032Since the
machine is in this state I come neither forward nor back. It would be great if you have a tip.
Many thanks Sascha
