I have an error code E10 appearing on my washer dryer a couple of minutes into a dry cycle. I have seen responses to this problem stating to replace the 3 way inlet valve. However if I do a continuous wash/dry cycle, the machine works fine. This would suggest that the inlet valve is working.
It sounds like your solenoid on the 3 way valve is faulty i had this problem last month, i bought 1 for £25 inc postage it took me 10 mins to fit and its spot on now
