Failed ACH transaction

[ssuccess]

A user is trying to make an ACH payment from our portal but it doesnt work , I get an Error - the ABA code is invalid (but its a valid code..) , when he does the same payment directly with autorize. net portal, it does work. Can anybody advise?

This is the code:

/**
 * Debit a Bank Account
 * Use this method to process an ACH debit transaction using bank account details.
 * @param float $amount
 * @param int $routingNumber
 * @param int $accountNumber
 * @param string $nameOnAccount
 * @param string $bankName
 * @return array
 */

    string $eCheckType
