H0120400467 Genuine Spray Arm Diverter for Fisher & Paykel, Haier Dishwashers, Water Diverter for Upper and Lower Spray Arms

Haier part H0120400467 is a genuine spray arm diverter for Fisher & Paykel and Haier dishwashers. The diverter decides which spray arms receive water at each stage of the cycle, letting the dishwasher wash the racks in turn at full pressure. No model list has been recorded for this part, so check H0120400467 against your dishwasher's parts list, with the help of the model and serial number on the inner door edge.

One dishwasher rack not getting clean

Many dishwashers don't run every spray arm at once. A diverter, driven by a small motor or by water pressure, switches the flow between the spray arms. When it sticks or its seals wear, one rack is starved of water while another gets it all. The result is dishes that come out dirty on one level, a spray arm that barely turns, a clicking or grinding noise from the sump, or an error code linked to the diverter position.

Replacing the diverter

Switch off at the wall and turn off the water. Remove the lower basket, filter and lower spray arm to reach the sump area, then follow your model's service steps, as some diverters are reached from underneath. Photograph wiring and hose positions first. Fit new seals where they're supplied and run a short cycle to confirm every arm is spinning.

Questions about this part

How do I know the diverter is the problem?

If one spray arm never turns while the others work, and that arm spins freely by hand with clear jets, the diverter is a likely cause. Also check that nothing is blocking the arm's water feed before ordering.
