How to resolve an error problem AC LOW in IFB washing
This is an IFB Top-load washing machine control panel it has an AC low error. This is a power error that the input line has low voltage but in reality, the voltage is correct into line. So we will repair the PCB fix error ac low Now we have to check those resistances that take signals from the input line and delivered on the main microcontroller IC. That kind of resistances is 100 kilo-ohms above to up and we can find easy into the circuit you are seeing in figure 2. There is a resistance R1 560k. This resistance is a very important play role in the circuit R1 is a calibration resistance for line in voltages if the resistance will be increased. then show the error on display AC HIGH if the resistance value decreases then show an error on the display AC HIGH. without a pressure sensor, we cannot check the PCB for all functions so we have to attach the pressure sensor with PCB. You are seeing in figure 2 In most of the cases, R1(560K) is open. By replacing the resistance the
