Electrolux error code E10?

My Electrolux washer dryer EWX14450W is not working on the drying cycle. It starts up as normal on the drying cycle and then after 5-10 minutes stops and shows error code E10. I understand this code is related to the water inlet hose/filter and I have already pulled out the machine and checked the hose is not kinked, the water supply is turned on and cleaned the filter. What else could this be?
