Tub fills beyond the selected level and may overflow onto the floor — the pressure switch diaphragm has failed and can no longer signal the control board to stop the inlet valve.
Machine starts but no water enters the tub, or filling stops immediately — a stuck or open-circuit switch sends a false 'full' signal to the control board.
Washer pauses or cancels the cycle unexpectedly because the pressure switch sends an erratic signal; often accompanied by an error code related to water level.
Garments come out still soapy or dirty because the tub filled with far too little water, preventing adequate agitation and rinsing during the cycle.
Control board receives a continuous 'tub full' signal from a shorted pressure switch and refuses to open the water inlet valve, so the cycle never begins.
In some failures the switch misreads the water level, causing the drain pump to activate at wrong times or leaving standing water in the tub at cycle end.
💡 Pro Tip: Diagnosing a Faulty Water Level Pressure Switch
Your part is likely the culprit if you notice any of the following:
⚠️ Washer tub overfills and water leaks onto the floor during the fill cycle
⚠️ Machine stops mid-cycle as if it never detected the correct water level
⚠️ Washer will not fill at all even though water supply valves are fully open
⚠️ Clothes come out under-rinsed because the tub filled with far too little water
🛠 Quick bench test: Disconnect the vacuum hose from the switch port and gently blow into it. You should hear an audible click from the switch as pressure changes. No click = failed diaphragm. Also inspect the hose itself for cracks, pinholes, or sediment blockage before condemning the switch — a leaking hose produces identical symptoms at zero cost to diagnose.
