failure on my Nespresso machine. So I removed, not without difficulty, but I can not find the problem. The mechanism is simple.
Here's what I tested: - Dismantling the pump is direct connection to 220V. Works - The heater is hot when I start the coffee maker. - The 2 thermal fuses on the heater are passing. - The temperature sensor looks good to me. It indicates 40Kohm cold 7kohm hot. I put in parallel with a 33K for the decline in 5Kohm hot, without success. I also declined to 3kohm to see, and then the machine will blink rapidly to indicate a pb when powering up. - The piping is not clogged. I plugged the pump Live 220 in the machine, and water flows.
So there I dry. Symptoms are: Brewer lights, the flashing green button until the desired temperature. Button stops flashing. -> Normal behavior. Once I start the coffee, the pump starts a split second and everything goes.
anyone know what it is possible failures on this unit.
How to test and that test? There is no trace of black. It consists of a triac, 5 capacitors and a microcontroller in CMS on the backside. I put a picture here: http://www.chocobon.fr/nespresso
600BW BTB12 triac is marked The 2 large capacitors are marked 220n and 470n with the white label on the next 470 - EF0049972 ST7850803 DPAK230V The 4 outputs are labeled from left to right: Heat Pump Neutral Line
