Jura x9 Magnetic switch

Hello together
,sometimes the machine makes coffee but after about 5min
.the solenoid switch of the drainage valve gets

permanent voltage 230V and moves the drainage valve

of the brewing group in.

The old magnetic switch was defective and

had a breakdown. This one's been replaced. When
voltage is applied
, it becomes noticeable
by a loud
hum. Do

I have an error

on the power board? Greetings

Hmm,very funny error,probably the reason for the damage of the old solenoid coil.
It can be interruptions, contact errors at the cable connectors or sensors with errors
.

I would first pull out the plugs cable by cable and put them back on again-two, three times-and to the next cable, then take out the power board if necessary and check for cold solder joints, but first take pictures of it as a marker-before agreing-the cables-.
