My Hoover VHD sensor dry washer dryer is showing an E03 error. I’ve read this is related to draining but I have been trouble shooting and can’t see that this is the issue. Filter clean. Sump tube has no obstruction. Drain pipe clean. Held it above a bucket and it worked. I have noticed that detergent is still in the drawer by the time the error shows at the top draining. Looking for advise/help.
