Good afternoon, they brought me a dream excellent 6.06 washing machine, in all the washing programs when starting it, send the 220 to the solenoid valve, start the drain pump for a few seconds, and when it simulated water level in the pressure switch (not to splurge water I blow the hose simulating level) automatically drains the drain pump and start flashing 7 times the three lights of the command, suggestions of what can it be?

Hello Federico. Error 7 is indicating an overfill problem. You may be blowing very hard. You should use a syringe and stop blowing air as soon as you hear the click of the pressure switch. Regards.

Look below in the forum they asked a similar question for another drean model but it is the same fault
