Washer model MTW6700TQ1 will not fill after starting. Will hum and then after 5 mins or so the LF code will appear. I opened lid, spin tub and then restart, and then wait until 5 mins or so for LF code to flash again. Must do this 3-4 times and then washer will start filling. It will run until the 24min rinse cycle and then the same thing happens. Open lid, spin tub and restart and after 3-4 attempts washer will fill and complete cycle.
I have tech repair manual for this washer, so I ran the automatic diagnostic test. During testing of test mode C1, C2, C3, C4 no water fill present.
It then tells me to run manual water inlet valve test, and same results, no water fill. It then tells me to disconnect P1 & P2 connector from motor control board, to then check harness connection to solenoid valves. It says to check resistance of valve coils at contacts P1 & P2 per diagram on page 7-1. Do I test resistance through the harness that I disconnected from control board or do I test each individual valve coil? I did not test through harness, but disconnected each coil and tested and all coils tested within specified 790-840 ohms, so it says to replace control board. Did I test this correctly??? I still need to visually inspect the transducer hose to check if plugged or pinched.
Thanks,
Itaska
