This genuine pressure switch, H0024000399A, tells Fisher & Paykel and Haier washing machines how much water is in the tub. It is listed for Fisher & Paykel WH1260P1 and WH1260F1 machines, the WH2424F1 and WH2424P1, and the WD7560P1 and WD8560F1 washer dryers. On the Haier side it covers the HWF12D1W1 and HWF75AW1, the HWF80BW1 and HWF85AW1, and the HWF85BW1 and HWF90BW1.

Washer overfilling, not filling or stuck on fill?

A thin air hose runs from the bottom of the tub to the pressure switch. As water rises, the air pressure in that hose climbs and the switch reports the level to the control board, which then shuts the inlet valve. If the switch fails, the machine may keep filling until water reaches the overflow, stop short of full, refuse to start the wash, or show a water level error. A split, kinked or blocked air hose gives the same symptoms, so check the hose and the small chamber at the tub end before replacing the switch.

Replacing the pressure switch

Pull the power plug from the wall first. Lift off the top panel to find the switch, usually mounted high on the side or back of the cabinet. Note the plug position, pull the air hose off, then unclip or unscrew the old switch. Fit the new one, gently blow through the air hose to clear it before refitting, and run a cycle to check the machine fills to the right level.

Questions about this part

How do I tell if it's the switch or the air hose?

Pull the air hose off the switch and check it for water, splits or kinks. If the hose is clear and sealed but the machine still misreads the water level, the switch is the likely fault.
