A frequency conversion board changes the frequency of the power it supplies, which lets a motor run at variable speed. In a dishwasher this normally drives the wash motor. Boards are model specific, so match the number on your old board before buying.\u003c\/p\u003e\n\u003ch2\u003eSigns of a failed dishwasher inverter board\u003c\/h2\u003e\n\u003cp\u003eDishwashers with a variable speed wash motor rely on this board to start the motor and set its speed for each stage of the program. If the board fails, the machine may fill and then sit silent, hum without spraying, stop partway with an error code or trip the power. Burn marks, a scorched smell or bulging components on the board are strong clues. Because a seized pump or a wiring fault can produce the same symptoms, it pays to check the motor and the connections before replacing the board.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Haier part number H0121800112\u003c\/li\u003e\n\u003cli\u003eHaier number 0121800112\u003c\/li\u003e\n\u003cli\u003eFrequency conversion (inverter) board for dishwashers\u003c\/li\u003e\n\u003cli\u003eSupplies variable frequency power for motor speed control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eChanging the board safely\u003c\/h2\u003e\n\u003cp\u003eSwitch off at the wall and unplug the dishwasher, or have a licensed electrician isolate it if it is hard-wired.
