I have a machine that has the same problem. Haven't taken it to be repaired as yet, but I was told they would give me an estimate prior to repairing it. My calculation is, "If the cost of repair is over priced, don't have it repaired but replace."
My reasoning is this, if the machine is out of warranty, which mine is, don't have it repaired. Your repair is warranted for 30 days only. My idea first is to see by reading your manual if you can correct the problem, save yourself some money. If you can't fix it yourself, then take the other solution.
