I have a candy CD797 smart dishwasher which until yesterday was working just fine. Now every time I switch it on it throws up E1 error code with a beeping noise. The manual says check water connection, which I have and it’s fine. It seems to be stuck on emptying, as at the beginning of a program it pumps out excess water before then switching to filling up with clean water. The pump is continually pumping out, as I tried manually throwing water in and it pumps it straight out again… 😥
