Every 3 or 4 wash the unit will stop part way through and send up error code 03. Nothing is ever blocking the drain. I reset it and set it to rinse and spin again. The frequency of this event is increasing - it makes a strange sound as it struggles to drain and then it sends up the error code - by reseting it and making it rinse and spin again it will end the cycle eventually end the cycle.

Any idea what the problem is? Does it need a new control board? Thanks!
