    Default Samsung WA5451ANW/XAA02 will not stop filling with water

    Model Number: WA5451ANW/XAA
    Brand: Samsung
    Age: 6-10 years

    Samsung WA5451ANW/XAA02 top load will not stop filling with water. It will kick into wash mode, but just continues filling. I’ve tried several things to test the water pressure level sensor switch and the water intake valve. I actually went ahead and replaced the water intake valve and hose.

    1) water intake valve: unplugged washer from electrical outlet while filling, the water stopped.
    2) pressure level sensor switch:
    a. removed the hose end from the switch and blew into hose, there was no obstruction going into the drum.
    b. Removed hose from drum end, leaving it connected to the switch. Started fill cycle and after filling with enough water, blew into hose. The water stopped. This also appears to test the “hole in the hose” thought.
    3) unplugged unit overnight

    The washer just continues filling, even when the wash cycle begins. If the water intake valve and pressure level sensor switch appear to be working properly, then what next?

    The only thing that changed and the difference between filling and not filling was the hose not being connected to the tub. Will it stop filling on a low water setting? I would recheck the hose connections, sounds like an air leak.

    Thanks Rick, did the further testing - submerged hose, no holes. Reattached the hose to the drum and duct taped the heck out of the connection there, including the surrounding drum (about 2” worth). No luck. Next thought, electrical?

    Is the air in the hose tripping the pressure switch when it's suppose to?? If not, you're right back where you started.

    If I disconnect the hose from the drum and blow into it, basically applying the pressure to the water level pressure switch, the water will shut off. Why wouldn’t the air pressure from the tub through the hose to the switch not be enough to trip it? As described, I put duct tape on the connection where the hose connects to the drum (to two inches out width wise), so there shouldn’t be leakage. And the hose, which is brand new, does not have any holes. I had also checked the flow from the hose into the tub and there didn’t appear to be any blockage. I’m baffled.

    I once had a problem similar to yours that had me scratching my head. I could blow through the pressure switch hose into the tub no problem but couldn't get any air from the hose to trip the pressure switch. Turned out to be a piece of lint and mineral deposits caught on the tub right above the pressure switch hose closing it off working like a flapper valve. I could blow it away through the hose but it just covered the hose back up. It was a different style than yours.

    Huh, interesting. In a case like that, the inner drum would need to be removed correct? Not sure how difficult that is with a Samsung. I'll look for a DIY. Thank you!
