Power button pressed continuously for more than 12 seconds; Switch jammed or stuck due to uneven pressing from control panel deformation; Sub PBA holding screws tightened too much; Button other than Power pressed continuously for more than 30 seconds; Deformation of internal plastic injection part; Main relay connections incorrect; PBA main switching IC on/off error; Micro switch gap issue

First Thing to Check

Parts Involved

How to Fix

1. 1

   1. Check whether the Power switch or a tact switch is pressed continuously

2. 2

   2. Check the contact between control panel buttons and their corresponding tact switches

3. 3

   3. Check whether the service PBA holding screws are fastened too tight — if so, loosen them a little (there must be a gap between a control panel and its corresponding button)

4. 4

   4. If PBA main switching IC on/off error has occurred, replace the main PBA

5. 5

   5. Check the main relay connections — the E2 error occurs if the main relay connections are incorrect (error occurs after approximately 30 seconds have passed)

6. 6

   6. If there is no error in the connections, replace main PBA

7. 7

   7. Check the resistance for Reed SW (checking part: White-Green wire) — resistance: approximately 0.2 ohms
