AWM8121 Fault Code - No Water

[quickfox12]

4 Years Old AWM8121 won't complete washing cycle. At the start of rinse cycle, it will stop, and LED lights in Prewash and Speed 0 will just blink. As per test sequence, this is due to faulty inlet valves. I tested with Cold-Faucet Off with just hot water flowing, got same fault code. I repeated the test, with just Hot-Faucett Off, same result. At the prewash stage of both tests, I can see water coming in at the back of the dispenser. Could this be a program error ? Or should I replace the inlet valves?

Update:

Removed the cold inlet valve and checked the flow. I compared this with the hot inlet valve flow. The cold inlet valve is flowing very slow. I switched them , with a little hack on the plastic insert that you attach to the solenoid part. There are three tiny protrusions where I have to cut off the third one to make it similar to the other one. Voila...the washing machine is working perfectly....I will try to buy the cold inlet valve though and replace my hack. I'm not sure what is the long time effect of using the hot inlet valve for the cold water...Any idea?

Worked perfectly since the hack, but the fault started again today. Guess I have to buy the solenoid valve now!
