WCF Exception: The maximum message size quota for incoming messages (65536) has been exceeded

Question

When I call a WCF service I get an exception:

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

When I use Wireshark packet analyzer filter on http the larges packet sent is 1226 bytes, which is way bellow the limit of 65536 bytes. Any suggestions to why this exception is thrown?

Code that I suspect causes the exception:

public LoanPlan CalculateLoanPlans(string productName)
{
    var loanPlan = new LoanPlan
    {
        Details = new[]
        {
            new PlanDetails {LoanAmount = 5000, Periods = 6},
            new PlanDetails {LoanAmount = 5000, Periods = 12},
            new PlanDetails {LoanAmount = 5000, Periods = 24},

            new PlanDetails {LoanAmount = 10000, Periods = 6},
            new PlanDetails {LoanAmount = 10000, Periods = 12},
            new PlanDetails {LoanAmount = 10000, Periods = 24},

            new PlanDetails {LoanAmount = 15000, Periods = 6},
            new PlanDetails {LoanAmount = 15000, Periods = 12},
            new PlanDetails {LoanAmount = 15000, Periods = 24},

            new PlanDetails {LoanAmount = 20000, Periods = 6},
            new PlanDetails {LoanAmount = 20000, Periods = 12},
            new PlanDetails {LoanAmount = 20000, Periods = 24},

            new PlanDetails {LoanAmount = 30000, Periods = 6},
            new PlanDetails {LoanAmount = 30000, Periods = 12},
            new PlanDetails {LoanAmount = 30000, Periods = 24},

            new PlanDetails {LoanAmount = 40000, Periods = 6},
            new PlanDetails {LoanAmount = 40000, Periods = 12},
            new PlanDetails {LoanAmount = 40000, Periods = 24},

            new PlanDetails {LoanAmount = 50000, Periods = 6},
            new PlanDetails {LoanAmount = 50000, Periods = 12},
            new PlanDetails {LoanAmount = 50000, Periods = 24}
        },
        TaxProcent = _taxPercent,
     };
     Parallel.ForEach(loanPlan.Details, detail =>
     {
         var result = Calculate(productName, Convert.ToInt32(detail.LoanAmount), detail.Periods, null);

         detail.ActualPaymentCost = result.ActualPaymentCost;
         detail.CreditCost = result.CreditAmount;
         detail.MonthlyPayment = result.MonthlyPayment;
         detail.MonthlyPaymentCost = result.MonthlyPaymentCredit;
     });

     var firstDetail = loanPlan.Details[0];
     var firstResult = Calculate(productName, Convert.ToInt32(firstDetail.LoanAmount), firstDetail.Periods, null);

     loanPlan.MonthlyFee = firstResult.MonthlyFee;
     loanPlan.MonthlyInterest = firstResult.MonthlyInterest;

     return loanPlan;
}

The Calculate method contains the servicecall.

Increase maxStringContentLength & maxArrayLength="2147483647" on both server and client. Check the below link which explains in detail
