How to reset Angular Material form fields to remove validation error?

Question

Angular

I have a form field

<mat-form-field >
  <input matInput 
    placeholder="Password" 
    [formControl]="passwordFormControl"
    [errorStateMatcher]="matcher"
    [(ngModel)]="password">
  <mat-error *ngIf="passwordFormControl.hasError('minlength')">Please enter at least 4 symbols</mat-error>
  <mat-error *ngIf="passwordFormControl.hasError('required')">Password is required</mat-error>
</mat-form-field>

After sending the data, I reset the value And I can not remove the message "Password is required" in any way. No manipulations help. How to do it correctly? this.password='';
passwordFormControl

As always, I found the solution myself.
