When the ERR4 error appears on the display of the Haier electronic washing machine, this usually happens when the high temperature mode is selected. Such a program may not start at all, then the unit does not respond to pressing the start button. It happens that the fault code knocks out during the cycle, a few minutes after the start or in the middle, or the wash ends, but the water remains cold.
Before the arrival of the mechanic, you need to try to fix the problem yourself. Error ERR4 may occur due to a temporary failure of the control board. It is enough to reboot it to correct the situation. To do this, the machine must be disconnected from the network, let it stand for 10-15 minutes, and then turn it on again.
Error ERR4 means that the heating element or the heating element has broken. If the problem is in the wiring or contacts, then the master will repair it. But most often, the replacement of the heating element is necessary. Rarely, but the cause may be a faulty control board.
