Re: Indesit WIDL 126 error codes 1+3
Buttons 1+3 supposedly indicate a fault in the water level control/pressure switch area. However if the facia module has had water on it then it could be causing spurious messages, the pressure switch is nowhere near the front console.
The best advice I can give is to see if we have someone in your area who can take a look, click the link in my sig.
Please remove the mains plug if you intend to go further yourself.
