Re: Hotpoint Aquarius FDW60
The user manual probaly won’t tell you to be honest.
1+3 flashing means the filters are blocked according to Merloni (Ariston) the manufacturer.
It’s probably not draining quickly enough, check the outlet spigott where the drain hose connects to the sink trap (if it does) as they block easily there 🙂
If you decide to look any further, please power off :zap: or if you need an engineer please check the repairs@ link below.
