kenmore washer F33 error code changed board and pump its functioning but shuts off during mid cycle

Too many digits in your model number . The actual model number should be 110.45088404. The F33 fault code indicates that the wiring connection between the pump and CCU (central control unit or main control board) is lost. This can be caused by a loose wire harness connection at the pump or the CCU. It could also be caused by a bad pump motor.
The first step in troubleshooting this problem would be to unplug the washer and check the wire harness connections between the pump and the CCU. To access the pump, remove the screws on the bottom of the lower service panel on the front of the washer. Pull the service panel out and down to remove it from the washer. To access the CCU, remove the screws on the back of the top panel and pull the top panel off of the washer. The wiring diagram below shows the connector for the pump on the CCU.If the wiring connections are okay, check the resistance of the pump circuit through the wiring connection at the CCU. With the washer unplugged, the resistance through the wires that connect to the pump should be around 12.3 ohms. If the circuit is open (measures infinite resistance), check the resistance on the leads of the pump motor. If the motor is bad, it will need to be replaced. If the motor measures the proper 12.3 ohms, then the wiring harness would need to be replaced. If the pump circuit is okay and the F33 will not clear, then the CCU will need to be replaced. since yo have replaced both CCU and drain pump you must have a bad connection or bad wiring harness. If you cannot find loose connection you will have to replace main wiring harness.
