Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! That error means the control module is getting a signal from the pressure switch that the water is not draining. Since we know the water is draining, the issue is likely with the pressure switch. Remove the filter and carefully clean the area under it, paying attention to the area on the right. Clean the area very well with boiling water, several times, if necessary. If no change, the pressure switch will probably need to be replaced. Let me know what happens.

I've taken the filter out and there is a black grate to the right, not very visible. I've tried cleaning. There is a about an inch of water still sat at the bottom of the filter hole which I can't scoop out. Still flashing 4 times
