zanussi zwf1640s

hi ,i am wondering if any one can give me any advice.i have a zanussi jetsystem timeline 1600,which work great till last week.when it stopped taking in water ,after checking the filters on the inlet hose and the pump as well as a general gander inside to see nothing had come loose.decided that the inlet valve solenoid had gone so i ordered the part and three days later it arrived.i replaced the part and yes nothing happened looking back. i think i jumped the gun the next day i tried it again and i worked for a couple of washes and then it stopped before the rinse came on it then came up with the error code e30.we have tried it a couple of times and if it works it will only wash then doesnt rinse or spin and no error codes come up has anyone any ideas i have read through the forums and cannot even find my model mentioned.thanks for reading this 😯
