H0120202675 Genuine Upper Spray Arm Flap Valve for Fisher & Paykel, Haier Dishwashers, Water Feed Flap for the Upper Sprayer

This genuine flap valve, part number H0120202675, sits in the water feed to the upper spray arm on Fisher & Paykel and Haier dishwashers. It's a small part, but it has a big say in how hard the water hits the top basket. Flap valves like this are fitted inside a housing that carries its own part number, so check whether you need the flap alone or the housing as well.

Weak spray in the top basket? Check the flap valve

Wash water leaves the pump and is shared between the spray arms through a set of pipes and ducts. A flap valve in the upper arm's feed controls how water passes into that branch. When the flap warps, tears or sticks, water can bypass the upper arm or spill out before it gets there. The usual result is poor washing in the top basket, an upper arm that barely turns, or water squirting from the duct at the back of the tub during the wash.

Fitting the flap valve

Power off at the wall and remove the upper basket. Depending on the model, you may need to unclip the top duct cover or take off the upper spray arm to reach the valve housing. Take a photo before pulling anything apart. Seat the new flap exactly as the old one sat, check it moves freely, then reassemble and run a rinse cycle while you watch for leaks.

Questions about this part

Is this the whole valve or just the flap?

The part is listed as the upper spray arm flap valve. The housing it sits in has its own part number, so if your housing is cracked or its mounting points are broken, order that too. Send your model through the parts enquiry form if you're unsure.
