Fix Kenmore Dishwasher Won't Fill with Water
Most likely the water inlet valve has failed or scaled shut, but first confirm the supply is actually on. On the common 665-prefix (Whirlpool-built) Kenmore, a no-fill often stores an F8E1 code — no water detected within the expected fill time.
Identify who built your Kenmore first#
Kenmore does not build its own dishwashers, and the model-number prefix tells you who did: 665 is Whirlpool, 630 is Bosch, 587 is Frigidaire, and 795 is LG. That matters because the parts, diagnostic procedures, and part numbers all map to the actual manufacturer, not to the Kenmore badge on the door. The most common units in service are the 665-prefix models, which share Whirlpool's inlet valves, float switches, control boards, and F#E# codes — this guide centers on those and notes the others where they differ.
A no-fill shows a recognizable pattern: the cycle starts and you hear the control click and the drain pump briefly run, but no water enters. On 665 models the board eventually posts an F8E1 code, meaning no water was detected within the expected fill time. A buzzing from beneath the unit during that window is the inlet valve trying and failing to open.
Causes ranked by likelihood#
| Likely cause | What you see | Fix |
|---|---|---|
| Water inlet valve (W10872255) — most likely | Buzzing under the unit but no water enters | The solenoid energizes but mineral deposits keep the valve from opening; replace it, since the deposits cannot be cleaned out. |
| Closed supply / angle stop | No fill and no buzzing | Open the angle-stop valve under the sink and confirm the supply line is not kinked. |
| Stuck float switch | Tub stays empty; float sits high | Free the float and test the switch beneath it; replace if stuck. |
| Door latch not confirming (F5E1) | F5E1 stored; cycle will not start the fill | Test the door latch switch (W10862259); the board will not fill until the door reads closed. |
| Low water pressure | Slow or partial fill during peak-use hours | Dishwashers need about 20 PSI; check pressure at the supply and address household causes. |

Check it yourself, in order#
- Shut off the water at the angle-stop valve under the sink before you inspect the inlet valve or hoses.
- Find the model number inside the door frame and read the prefix to confirm the manufacturer (665 Whirlpool, 630 Bosch, 587 Frigidaire, 795 LG).
- Start a cycle and listen: a buzzing that never becomes water is a solenoid energizing against a stuck valve.
- Confirm the supply is fully open and the fill hose is free of kinks, then check for an F8E1 no-fill code on 665 models.
- Inspect the float in the tub floor; if it sticks high the control believes the tub is full and will not add water.
- Access the inlet valve with the correct driver — 665 platforms use T15 and T20 screws — and replace it if the screens are clear but no water passes.
Prevent the repeat#
Hard water is what scales an inlet valve shut, so a home with heavy mineral content will see this again unless the water is softened or the valve is serviced periodically. Keeping the float free of food debris and confirming the angle stop under the sink stays fully open are the two simplest ways to avoid a repeat no-fill call.

Repair or replace?#
A no-fill is nearly always a valve, a float, or a supply issue — cheap fixes relative to a new [dishwasher](/blog/repair-or-replace-dishwasher). Since the same W10872255 valve serves Whirlpool and KitchenAid units too, parts are easy to source on 665 models. A technician can confirm the valve versus the float in one visit.
