Nivona nicr730 дисплей гаснет через 3 секунды.

Hello.My nivona nicr730 had little flooding while making coffee and the grinder started to spin constantly.when .I disassemble the machine and i changed the responsible triac.Now when I push the power button,the display goes off in 3 seconds.I disconnected the pump and grinder, nothing changes, after that  when disconnect  only the heating(test with another heater for shortage, but not helped),the machine stayed switched on.Would you help me what to check, which control voltage .Is it the problem with triac,or the problem is other

turn off the gear motor and see how the device behaves

[anio83]

A day before i noticed that the machine stays on when the heater disconnected.Tried with a new one ,the problem remains the same. I will check without gear motor

I noticed that the machine turns off when a message appears on the display about the start of heating.  Check the section of the circuit responsible for heating the boiler.

On the power supply board, after the output winding of the transformer, the Schottky diode burned out. Replacement.

Its all

ok , i purchased new triac bta212 -600 and i ll check all the elements in the circuit of the heater.

Its all

ok , i ll change also the shottky diode,but would you tell me is that 2Amperes , the information is on one site is 1 ampere ,the others gives 2amperes
 AS i found it s vishay shottky diode 1Amper and it s VS-10BQ100-M3 ,but in other themes i saw it s about 2,1A

I changed triac bt212-600b ,the electrolytic capacitor and Schottky diode . The problem remains, nothing change . I can t find any element with shortage

[yeskoles]

The Schottky diode strictly needs to be set at 2-4 Amperes. The higher, the better. The problem arises from excess current on the gearbox shaft, all because of it, the gear rotates tightly in the gearbox.
I installed a dual diode in a TO-220 package from a switching power supply.

I changed the diode and the situation is the same,i hear light histening sound when the power board works, is it capacitor,i ll check this one of the primary circuits
