remove both the supply pipes to machine, run each into a bucket one at a time, PROVE you have found the COLD supply, swop pipes and PROVE that you have found the HOT supply reconnect each to there own tap connection.
ie HOT = RED PIPE BLUE = COLD
If water supply is O K you may have to look for a faulty thermostat hence the hot water due to the heater not turning off . If no transit screws were used during the move internal wire(s) may have pulled off .
