When the ERR7 error appears on the display of the Haier electronic washing machine, this is accompanied by the failure of the unit to start. Most often, a fault code appears immediately after turning on the machine in the network. It happens that it occurs after selecting the program and pressing the start button. The washer does not respond at all.
Before the arrival of the service center, you need to try to fix the problem yourself. Error ERR7 means control board failure. It may be temporary. It is enough to restart the module to correct the situation. To do this, the washing machine must be disconnected from the mains, let it stand for 10-15 minutes, and then turn it on again.
If the reboot did not help, then the control board is out of order. The master must diagnose the unit. Error ERR7 is critical, most likely when it appears, the module can no longer be repaired. Only replacing the entire board will help.
