Как сбросить валидацию после отправки формы?

const blankForm = {
  branch: '',
  department: '',
  designation: '',
  mobile: '+91 '
}

clearNewShow() {
  this.formValues = {...blankForm}
  this.$validator.pause()
  this.$nextTick(() => {
    this.$validator.errors.clear()
    this.$validator.fields.items.forEach(field => field.reset())
    this.$validator.fields.items.forEach(field => this.errors.remove(field))
    this.$validator.resume()
  })
}
