H0121800129 Genuine Dishwasher Main PCB with Box Cover for Haier, Fisher & Paykel Dishwashers HDW13V1W1 HDW13V1S1 HDW13V1G1 HDW15V2S2 HDW15V2B2

Here is the genuine Haier main control board H0121800129, supplied with its box cover. On these dishwashers the main PCB is mounted down in the base rather than up in the door. It is listed for the Haier HDW13V1W1, HDW13V1S1 and HDW13V1G1, along with the HDW15V2S2 and HDW15V2B2. Fisher & Paykel and Haier share this part number, so you may see it under either brand.

Haier dishwasher not starting or stopping mid-cycle

The main board is the brain of the machine. It powers the wash and drain pumps, opens the inlet valve, switches the heater and steps through each program based on signals from the sensors and the control panel. A failed main board can leave the dishwasher completely dead, stuck partway through a cycle, filling but not washing, or showing an error that keeps coming back. Water leaking into the base can also damage it, so find and fix any leak before fitting a new board, or the replacement may suffer the same fate.

Fitting the main board

Turn the dishwasher off at the power point and unplug it, then shut the tap and slide the machine out so you can reach the base. Photograph every connector on the old board while it is still in place. Discharge static from your hands by touching bare metal, and hold the new PCB by its edges only. Seat each plug firmly, refit the box cover, then run a test cycle.

Questions about this part

Is this the display board or the main board?

H0121800129 is the main board, which sits low in the dishwasher. The buttons and display are normally on a separate board, so if only the display is dead, check that board and its cable as well before ordering.
