What Are The Reasons For E16/e17 Preheating Failure?

1. The heating ring on the pot wall is less than 80 ℃ for 10min.

2. The steam generator is less than 105 ℃ for 10min.

solution: first, use hands to sense whether there is heating, and observe whether the corresponding indicator light of the main board is on. Use a multimeter to measure whether the main board has 220V electric output, and under the condition of voltage output, whether there is a resistance value in the quantity or not, the resistance value of the evaporation heating rod is generally 33 Ω. Replace the steam generator without resistance.

What Are The Reasons For The Failure Of E08?

1. Solenoid valve leaks(It is mainly the air leakage between the normally open solenoid valve and the two-position tee. Use the needle holder to clamp the high-pressure pipe of the solenoid valve. The temperature and pressure rise rapidly, which corresponds to the air leakage of the solenoid valve. Open the solenoid valve core to clean up foreign matter or change the solenoid valve)

2. Water inflow fails(1. Observe whether the water pump is working. 2. Check whether the filter screen at the front end of the water inlet pump is blocked. 3. Main board control output 220V)

3. Air leakage (the naked eye to judge whether there is hot air from the edge of the door seam, adjust the door tightness or replace the sealing ring)

4. Serious pipeline leakage (check whether there is obvious water falling at the bottom of the machine, and check whether the pipe is broken)

5. Evaporator(evaporator heating failure, evaporator blockage.)
