Common fault of Westinghouse wall breaker: 1. Wrong function key is selected. What is the wrong function key? For example, if you want to grind Chili powder and put dried Chili into the cup of the wall-breaking machine, but press the function button of soybean milk by mistake, the wall-breaking machine will naturally report an error and stop working. Anyway, soybean milk needs to be heated, and it is impossible for the machine to handle the function of dry grinding with a heating program. There is no water in the cup. Some functions need water to trigger the machine to start, such as fruit juice, soybean milk, rice paste and so on. Otherwise, it can't be done. Forced starting will damage the machine, so the error E 10 stops working. 3. Too many ingredients are added. If the machine judges that too much ingredients are added, it will affect the mixing or overflow after mixing, and there will also be an error of E 10.
