How could you exclude certain error codes in array string?

The below example does not seem to filter errors from my array.

Ex.

$IgnoreErrorCode=@(

'1608',

'17832',

'17824',

'18456';

)

# Write-Host "Reading SQL Log for $sqlServerName"

try{

$sqlServer.ReadErrorLog() | Where{$_.LogDate -is [datetime] } |

Where-Object{$_.LogDate -gt $DatetoCheck } |

Where-Object{$_.Text -like "*Error*" -or $_.Text -like "*Fail*"} -and ($_.Text -notcontains $IgnoreErrorCode) |

Select-Object LogDate,Text |

Out-GridView -Title "$sqlServerName Log Errors"

} catch {

Write-Host "Error Reading $sqlServer.Name"

}
