Hi guys, I have trouble for a while with my dishwasher D1484CF, which two buttons I will need to press to operate pump manually? I did try all combinations and I cant get that working. I did change 2 new pumps, moves drainage house, checked ohms on pumps, all good in range, voltage looks fine coming from main board etc and I still cant get that working. Last engineer came and replaced main board but that didn’t solve the Problem. One or two cycles will run ok and than again OE error. I hate that sound now. 4 times engineer appointment was cancelled On that day, so keep calling LG about new appointment date. Its been two and half months now and still not working. I did try everything and i am at the stage probably buy new dishwasher. Any other suggestion what to try before I will …
