Lg Washer wm2487hwma. Water valves only function in test mode

19 February 2014 - 06:34 PM

I have a customer with a LG washer model wm2487hwma. The customer was getting a IE code ( water flow problem) . The customer purchased and installed a new hot and cold water inlet valve because the machine wasn't letting any water in. The customer then tried the machine again and the same problem of no water flow continued.

This is when I received the service call. Upon arrival the customer showed me that no matter what wash cycle was selected no water ever came in. He also showed me that when you run the machine in test mode the water valves did come on. This made me suspect a main board issue. I contacted LG tech support and they agreed with my assessment . So a day later I took out the old board and put in the new one. The problem continued until I ran test mode first and after that completed I ran the machine in normal wash and everything was working. I called the customer over and began a normal cycle again and of course the pain in the butt machine decides to go right back to its old problem of not letting water in again.

I tried unplugging the unit to let it discharge and then plugged it back in and tried running a regular cycle again. Still having the same issue.  I don't really think I got a bad board because the new board was causing the same problem as the one I replaced. Again I called LG and they said its the board. UGH!!! I pulled out the new board and I am sending it in for a warranty return.


Does anyone have any idea if anything other than the board can be causing this problem? I hate to install another expensive new board and possibely wreck it too.
