Philips GC 7636 iron - the generator does not produce steam, but hums when turne

Hello,
the iron was never used, but lay for several years on the shelf.
In the iron, the foot heats up after approx. 2 minutes. it is ready to work, but after switching on it does not produce steam, you can hear the steam pump beeping loudly. The cables that are connected to this pump are about 12-15V when turned on, and should be 220-240V. The fault probably lies with the electronics. What can I check and possibly replace?

Please do not pick me up wrong, but it seems to me that you do not have much in common with electronics on a daily basis, judging by the measurements.

I suggest starting the pump and using a syringe to give water under pressure, i.e. push it to work

I injected water under pressure with a syringe, but it did not work, I measured again on the pump and it came out the same, about 15V. I connected the pump directly to 220V, it beeps even louder, and it does not consume water, I think I'll start with replacing the pump. But I still do not understand why there is so little voltage to the pump after turning on the iron? Electronics is probably to blame.

Hello, I have a similar problem with the voltage on the pump ( I have about 90 - 120V from 230V ), the strangest thing is when I switch on the descaling mode, then the pump works perfectly and there is 230V on it, while when I start the steam with the button on the iron it is again too low, I also checked if maybe there is some resistance too high between the station and the switch in the iron.... But there it is fine, have you solved the problem perhaps?

PS: I will try to replace the capacitors for the low power supply of the prock area to start with, I will also check what is happening on the gate of the switching triac, in descaling mode vs normal operation, regards.


EDIT:
I did not find a fault, but I observed that the processor puts out 5V on the output and 2.5V for the pump when I activate the switch to steam, in cleaning mode it is correct 0V and the pump works, as I did not find a solution, I take the switching signal from another processor pin that switches on the solenoid valve separately and at one moment I switch on both devices - The strange thing is that on the pin responsible for controlling the solenoid valve the states that the processor puts out are already correct, and on the pump pin there is this strange 2.5V as if it was signalling a fault at the moment of coupling the steam with the switch in the iron

PS: I just don't know why the manufacturer controls the pump and the solenoid valve separately, since both devices are always switched on at the same time anyway, whether in normal steam generation mode and cleaning/decalcifying mode.
...Maybe someone can explain this below, regards.
