Dont set a value like that.
Set a value like it used to be in Ionic with NgModel

.ts file

// Define before your constructor as:
sDefaultEmail   :  string;

constructor()
{
    sDefaultEmail = 'example@gmail.com';
}

.html file

[(ngModel)]="sDefaultEmail"
5

bind the input value with a variable and initialize it with some value
.ts file
email:string=‘default@email.com’ before the constructor of page
and bind it with ngModel

<ion-input type=“email” [(ngModel)] = “email”>

and also use input type email instead of text
