Kenmore Washer Overflowing — What’s Happening
A Kenmore washer overflowing means the machine is overfilling or not stopping the fill at the proper level. This is a symptom, not a single fault code. In most cases, the water inlet valve has failed and is mechanically stuck open, or the pressure switch system that monitors water level is not sensing correctly.
If the tub keeps filling even when the washer is unplugged, the inlet valve is leaking past its seat. If the machine fills too high before stopping, the pressure switch or the air hose connecting the tub to the switch has failed or become blocked.
Most Likely Causes
- Water inlet valve stuck open The solenoid or valve seat has failed, allowing water to continue entering the tub even when power is removed.
- Pressure hose disconnected, pinched, or clogged The air tube between the tub and pressure switch is off the nipple, kinked, cracked, or blocked, so the switch cannot detect rising water level.
- Pressure switch failure The switch does not open the fill circuit at the set level, even when hose pressure is correct.
- Air dome or tub port clogged Debris, suds residue, or buildup at the tub pressure port prevents air pressure from transferring to the switch.
- Low household water supply pressure Incoming water pressure below 20 psi can prevent some inlet valves from closing fully, causing seepage or overflow.
- Control energizing valve at wrong time The timer or main control board is sending power to the inlet valve when it should be off.
- Cycle selector mispositioned or not engaged On older mechanical models, a water-level or cycle knob that is not fully set can prevent the correct fill cutoff.
How to Diagnose and Fix
- Unplug the washer and turn off both hot and cold supply valves, then watch whether water still enters the tub. If it does, replace the water inlet valve.
- Locate the pressure hose running from the outer tub air dome to the pressure switch (usually a small-diameter clear or rubber tube). Inspect it for being disconnected from the nipple, pinched, cracked, or filled with debris.
- Check the tub air dome port at the outer tub for clogs from detergent residue, lint, or suds buildup. Clean the port and hose if restricted.
- Remove the pressure hose at the switch end and gently blow through it to confirm it is clear. Reconnect it firmly and verify it seats fully on both the tub nipple and switch nipple.
- Test the pressure switch by slowly blowing into the hose while listening for an audible click or using a meter to check continuity change. If the hose is clear and the switch does not respond, replace the pressure switch.
- Verify household water pressure at the supply valves. If pressure is abnormally weak or fluctuating, correct the supply issue before replacing parts.
- If the hose and switch are good, check that the control is only powering the inlet valve during the fill portion of the cycle. If the valve is energized at the wrong time, the control board or timer may be faulty.
- After repair, run a fill test on a small load setting and confirm the washer stops at the correct water level and does not continue filling.

When to Call a Pro
Call a technician if you are uncomfortable working with water supply plumbing, if you cannot locate or access the pressure switch and hose on your model, or if the washer continues to overflow after replacing the inlet valve and verifying the pressure system. A pro can also diagnose control-board faults that energize the valve at the wrong time and can safely test electrical circuits while the machine is powered.
